In Durban’s heat and humidity, a broken air conditioner is not a minor inconvenience — it is unbearable. Whether your unit stopped cooling overnight, is leaking water down your wall, making a noise that keeps you awake or simply will not switch on, you need it fixed today, not in three days when the next available booking opens up.
Appliance Repairs Durban has been repairing, servicing and regassing air conditioning units across all Durban areas for 22 years. Our certified technicians operate in fully-equipped mobile units that carry the most common aircon parts and refrigerant gas for all major brands. That means when we arrive at your home or business in Umhlanga, Westville, Chatsworth, Pinetown, Morningside, Hillcrest, Bluff or anywhere across the Durban metro, the repair or service begins immediately. No assessment visit followed by days waiting for parts. In most cases, your air conditioner is repaired or regassed in a single visit on the same day you call.
Durban’s coastal climate creates air conditioning challenges that are more aggressive than in inland cities. Salt air corrodes outdoor condenser unit fins, coils and electrical connections faster than in drier environments. High humidity causes evaporator coils to accumulate biological growth such as mould, bacteria and algae that reduces cooling efficiency, creates bad smells and can become a health concern. Durban’s high ambient temperatures cause compressors to work at the upper end of their operating range for more months of the year than almost anywhere else in South Africa, accelerating wear and shortening component lifespan. Our technicians have been diagnosing and repairing these specific Durban aircon fault patterns for 22 years.
Every air conditioning repair we complete comes with a full written quote before any work begins, genuine OEM parts and a 6-month workmanship guarantee. Our call-out fee is R350, waived if you proceed with the repair or service. No hidden charges. No surprise bill at the end. Just fast, honest and professional air conditioning repairs from the team Durban has trusted since 2003.

Our certified technicians diagnose and repair all air conditioning faults across Durban, including split units, cassette units, ducted systems and portable air conditioners for both residential and commercial properties. Whether your aircon stopped cooling, is leaking, smells bad or has completely stopped working, we have diagnosed and fixed it thousands of times across Durban over 22 years.
This is the most common air conditioning complaint in Durban. An aircon that is running but not cooling, or blowing warm air instead of cold, is most commonly caused by low refrigerant gas due to a leak, dirty or blocked evaporator or condenser coils restricting heat exchange, a failing compressor, a faulty reversing valve stuck in heating mode or a clogged air filter severely restricting airflow.
In Durban’s high ambient temperatures, even a partially degraded cooling system becomes noticeably ineffective. What works adequately in a cooler climate will not keep a Durban home comfortable. Our technicians carry refrigerant gas in their mobile units and can diagnose and resolve most cooling faults on the same day across Durban.
This is a very common Durban-specific complaint. When electricity is restored after a load shedding outage, the power surge can damage the aircon control board, trip the unit’s internal protection circuit or damage the compressor. An aircon that was cooling correctly before a load shedding outage and is not cooling afterwards has almost certainly suffered surge-related damage or has tripped an internal protection circuit.
Our technicians are specifically experienced in diagnosing post-load-shedding aircon faults across Durban.
Water dripping or flowing from the indoor unit of a split air conditioner is one of the most alarming aircon faults, particularly when it is dripping onto furniture, flooring or electrical equipment below. The most common causes are a blocked condensate drain pipe, a dirty evaporator coil causing excessive condensation, a cracked or disconnected drain pan or an incorrectly installed or sagging drain pipe.
Blocked condensate drains are extremely common in Durban’s humid climate where biological growth rapidly blocks drain lines. Most condensate drain blockages are cleared on the same day visit across Durban.
Ice forming on the indoor unit evaporator coil or on the outdoor unit pipes indicates one of two main faults: low refrigerant causing the evaporator coil temperature to drop below freezing, or severely restricted airflow across the evaporator due to a dirty filter or blocked coil causing the coil to freeze solid.
An iced-up aircon must be switched off immediately to allow the ice to melt before a technician can properly access and diagnose the underlying cause. Do not attempt to chip or remove ice manually, as this damages the delicate evaporator fins.
Air conditioners produce some normal operational noise, but a noise that is new, louder than before or different in character indicates a developing fault. Loud rattling typically indicates a loose panel, fan blade or foreign object inside the unit. Grinding or squealing indicates a failing fan motor bearing. Clicking at start-up that does not resolve indicates a compressor or control board fault. Banging or knocking indicates a loose or broken fan blade. Hissing indicates a refrigerant leak. Bubbling or gurgling indicates refrigerant flow irregularity, often associated with low refrigerant.
Each noise type points to a specific fault, and our technicians are experienced in accurate noise-based aircon diagnosis across Durban.
An air conditioner that will not power on at all usually has an electrical fault such as a blown fuse, a failed control board, a tripped internal protection circuit, a faulty remote control or receiver board, a damaged power supply or a compressor protection trip that has not reset.
Before calling us, check that the power supply is working, check the aircon circuit breaker at your DB board and try resetting the unit by switching it off at the isolator switch for 30 seconds and switching it back on. If these steps do not resolve the problem, contact us.
A musty, stale or unpleasant smell from an air conditioner is one of the most common Durban aircon complaints. It is almost always caused by biological growth on the evaporator coil and in the drain pan. Durban’s combination of high humidity, warm temperatures and the moisture that naturally accumulates on evaporator coils creates ideal conditions for mould, bacteria and algae growth.
The smell is not just unpleasant. Some of the organisms responsible can be respiratory irritants, especially for asthma and allergy sufferers. A thorough professional aircon service including coil cleaning and drain treatment resolves this problem in the vast majority of cases.
Durban winters are mild, but mornings and evenings can still be uncomfortably cool, particularly in inland suburbs like Hillcrest, Kloof and Westville. A reverse-cycle split air conditioner that is not providing heat in winter may have a faulty reversing valve stuck in cooling mode, low refrigerant affecting heat pump efficiency, a faulty outdoor fan motor or a control board fault preventing the switch to heating mode.
Our technicians repair aircon heating faults across all Durban areas.
An air conditioner that repeatedly trips your electrical board has a serious electrical fault requiring immediate attention. Common causes include a failing compressor drawing excessive current, a short circuit in the wiring or control board, a failed capacitor or a compressor protection fault.
Switch the unit off at the isolator switch and call us. Do not keep resetting the DB board as this can cause progressive damage to the compressor.
If your aircon remote control has stopped working, the fault is most commonly the remote itself, such as dead batteries, a cracked circuit board from being dropped or simple end of life. However, if new batteries do not solve the issue, the fault may be with the indoor unit receiver board.
Our technicians carry replacement remote controls and receiver boards for the most common aircon brands.
If your indoor unit appears to be running but the outdoor unit is not, the air conditioner cannot cool. Common causes include a failed outdoor fan motor, a tripped high-pressure protection switch caused by dirty condenser coils, a faulty capacitor, a failed compressor or a control board fault preventing the outdoor unit from receiving a start signal.
An aircon that operates with a running indoor unit but non-running outdoor unit is a common post-load-shedding fault in Durban.
An air conditioner that runs continuously without reaching the set temperature is working harder than it should and consuming far more electricity than necessary. Common causes include low refrigerant, a dirty filter or coil restricting airflow, an undersized unit for the room, a very hot Durban day exceeding the unit’s rated capacity or a failing compressor losing efficiency.
If your electricity bill has increased significantly and your aircon seems to be running all day without properly cooling the room, it needs attention.
In addition to repairs, our certified technicians provide a full range of air conditioning services across all Durban areas.
A full professional aircon service includes filter cleaning or replacement, evaporator coil cleaning, condenser coil cleaning, drain pipe clearing and treatment, fan blade cleaning, electrical connection inspection, refrigerant level check and a full operational test.
We recommend annual servicing for all Durban air conditioners, and more frequent servicing for units in coastal suburbs exposed to salt air. A properly serviced aircon cools more efficiently, uses less electricity, smells better and lasts significantly longer than an unserviced unit.
Service from R550
If your air conditioner is blowing warm or lukewarm air despite the compressor running, the most likely cause is low refrigerant gas. Our technicians carry refrigerant gas in their mobile units and regas all aircon makes and models across Durban on the same day you call.
Low refrigerant does not just reduce cooling performance. It causes the compressor to run hot and can lead to permanent compressor damage if left too long. A regas without locating and repairing the leak that caused the low refrigerant will only result in the gas escaping again. Our technicians check for leaks before regassing.

We are one of the few air conditioning repair companies in Durban to publish honest pricing openly. Here is what aircon repairs and services typically cost across Durban.
This covers your technician travelling to your Durban home or business, diagnosing the fault and providing a full written quote. The call-out fee is waived if you proceed with the repair or service.
This usually includes:
Full filter, coil and drain service for split units
Commercial cassette or ducted system service quoted on inspection
These commonly include:
Drain pipe clearing and treatment
Filter replacement
Remote control or receiver board replacement
Capacitor replacement
Indoor fan motor replacement
Electrical fault diagnosis and repair
These commonly include:
Compressor replacement
Control board replacement
Reversing valve replacement
Refrigerant leak repair and regas
Outdoor fan motor replacement
Complete electrical harness repair
This depends on the refrigerant type and quantity required, such as R22, R410A or R32. Leak repair is quoted separately if a leak is identified.
Parts are quoted separately at cost price and require your written approval before we order or fit anything.
If your aircon is less than 7 years old, repair is almost always the right decision, even for major faults. A well-maintained split air conditioner should give 10 to 15 years of reliable service.
If your aircon is between 7 and 12 years old, apply the Rule of 50. If the repair costs more than 50 percent of what a comparable new unit and installation would cost, replacing is likely the smarter long-term financial decision.
If your aircon is over 12 years old and uses R22 refrigerant, replacement is usually the better option. R22 is being phased out globally and is becoming increasingly expensive and difficult to source in South Africa. An older R22 unit requiring a regas or compressor replacement is almost always better replaced with a modern R410A or R32 unit that is more energy efficient, uses readily available refrigerant and will provide many more years of reliable service.
Our technicians will always give you an honest repair-versus-replace assessment at the time of their visit.

Durban’s coastal humidity, salt air, high ambient temperatures and load shedding create air conditioning challenges that are unlike any other city in South Africa. We have been diagnosing and repairing these specific Durban aircon fault patterns for 22 years, which means our technicians recognise faults faster, diagnose more accurately and repair more effectively.
Most aircon repair companies in Durban have to schedule a separate visit for regassing after an initial diagnosis. Our mobile units carry refrigerant gas for common refrigerant types including R22, R410A and R32. If your aircon needs a regas, it happens on the same visit in most cases.
Many companies offer either repair or servicing, not both. We provide the full range: diagnosis, repair, service, clean, regas and installation. Whatever your aircon needs, we handle it.
Our multiple mobile units operating across Durban simultaneously mean we can respond to aircon call-outs on the same day in many cases across Durban North, South, Central and West.
Every aircon repair we complete comes with a 6-month workmanship guarantee in writing. Many aircon repair companies offer shorter coverage or none at all. We offer 6 months because we are confident in our technicians, our parts and our diagnosis.
You will always receive a full written quote before any aircon repair or service begins. Labour, parts and refrigerant gas are itemised separately. You approve every cent before we start. No hidden fees. No inflated bills. No surprises.
Call or WhatsApp us on +27 79 976 2941. Tell us your aircon brand and type, the fault you are experiencing and your suburb in Durban. We respond within minutes and confirm same-day availability immediately.
A certified aircon technician in a fully-equipped mobile unit carrying refrigerant gas, cleaning equipment and common aircon parts is dispatched to your home or business, often on the same day you contact us.
Our technician inspects the indoor and outdoor units, tests the compressor, fan motors, refrigerant pressure, electrical connections and drain system. They diagnose the exact fault, explain it clearly and provide a full written quote before any work begins.
Once you approve the quote, we get to work immediately. Refrigerant gas, cleaning chemicals and the most common replacement parts are already on board. Most aircon repairs, services and regasses are completed in a single visit.
When the work is complete, your technician tests the unit for correct cooling performance, airflow, drainage and noise levels. Your 6-month workmanship guarantee is issued in writing. Payment is then processed by cash, EFT or card.
Our call-out fee is R350, waived if you proceed with the repair or service. Minor aircon repairs usually cost between R550 and R900 and cover faults such as drain clearing, capacitor replacement, remote control replacement and fan motor replacement. Major aircon repairs usually cost between R900 and R3,500 and cover faults such as compressor replacement, control board replacement and refrigerant leak repair. Aircon servicing costs between R550 and R900 for standard split units. Regassing costs between R650 and R1,200 depending on refrigerant type and quantity. You will always receive a full written quote before any work begins.
An aircon that is not cooling in Durban is most commonly caused by low refrigerant gas due to a leak, dirty or blocked coils restricting heat exchange, a failing compressor or a clogged filter severely restricting airflow. In Durban’s high ambient temperatures, even a partially degraded cooling system becomes ineffective much faster than in cooler climates.
We recommend annual professional servicing for all Durban air conditioners. For units in coastal suburbs exposed to salt air such as Umhlanga, La Lucia, Bluff and Amanzimtoti, servicing every 6 months is ideal. For commercial properties with aircons running daily, quarterly filter cleaning and annual full service is recommended.
Bad smells are almost always caused by mould, bacteria and algae growth on the evaporator coil and in the drain pan due to Durban’s humidity. A professional coil clean and drain treatment resolves this in most cases.
This is usually caused by a blocked condensate drain pipe, a dirty evaporator coil, a cracked drain pan or poor drain pipe installation. It is one of the most common Durban aircon faults.
Yes. Load shedding can damage control boards, capacitors and compressor windings through voltage surges when power is restored. It also increases wear through repeated start-stop cycles.
Servicing is preventative maintenance that keeps the unit clean, efficient and less likely to fail. Repair addresses a specific existing fault such as a failed component, refrigerant leak or electrical issue.
Try a full reset by switching the unit off at the isolator for 30 seconds and switching it back on. If that does not work, the surge may have damaged the control board, capacitor or compressor.
Yes. We regas R22, R410A and R32 units, including split units, cassette units, ducted systems and portable air conditioners. We also check for leaks before regassing.
Signs include warm air, slow cooling, ice forming on the unit or pipes, rising electricity usage, hissing sounds and reduced cooling performance on hot Durban days.
This is usually caused by low refrigerant or restricted airflow due to a dirty filter or blocked coil. The unit should be switched off immediately and allowed to thaw.
Yes. We repair and service commercial air conditioning systems for offices, restaurants, hotels, retail outlets and industrial facilities across Durban.
If your air conditioner is not cooling, leaking water, making unusual noises, smelling bad or has stopped working completely, do not wait for the heat and humidity to get worse.

When your aircon stops cooling in Durban’s heat you need to know exactly what is going to happen and how fast. Here is our complete process from the moment you contact us to the moment your aircon is blowing cold air again.
Step 1 — Contact Us by WhatsApp or Phone
Call or WhatsApp us on +27 79 976 2941. Tell us:
• Your suburb in Durban
• Your aircon brand, type and model if you have it — split unit, cassette, ducted or portable
• The fault or symptoms you are experiencing — not cooling, leaking water, bad smell, icing up, not switching on, making noise
• Whether the fault started after a load shedding outage — this is important information that helps our technician prepare the correct parts before arriving
That is all we need. We respond within minutes. We will confirm same-day availability for your area and give you an honest initial assessment of what the fault is likely to involve before anyone leaves our depot. For commercial properties where a non-functioning aircon is affecting business operations we prioritise your callout accordingly.
What happens at this step:
• We respond within minutes

• Honest initial assessment of the likely fault communicated upfront
• Commercial aircon callouts prioritised
• No deposit and no commitment required
Step 2 — A Certified Aircon Technician Arrives at Your Door
A certified aircon technician in a fully-equipped mobile unit is dispatched to your home or business — in most cases on the same day you contact us. Our mobile units carry refrigerant gas for all common refrigerant types — R22, R410A and R32 — as well as professional coil cleaning chemicals, drain clearing equipment and the most common replacement parts for all major aircon brands. Your technician arrives ready to repair, service or regas — not just ready to look.
This is one of the most significant operational differences between us and most other aircon repair companies in Durban. Most companies send a technician to assess the fault, return to collect parts or gas and then schedule a second visit for the actual repair. Our technicians carry everything they need on board — which means your aircon is repaired in a single visit in the vast majority of cases.
What happens at this step:
• Certified aircon technician dispatched same day in most cases
• Mobile unit carries R22, R410A and R32 refrigerant gas
• Professional cleaning chemicals and drain equipment on board
• Common replacement parts for all major brands carried
• You are informed of who is coming before they arrive
Step 3 — Full Aircon Diagnosis and Written Quote
When our technician arrives they will conduct a thorough inspection of both the indoor and outdoor units. The diagnostic process includes:
Indoor unit inspection:
• Filter condition — dirty, blocked or damaged
• Evaporator coil condition — clean, iced up or contaminated with biological growth
• Drain pan condition — clean, cracked or overflowing
• Condensate drain pipe — clear or blocked
• Fan motor operation — running smoothly or showing signs of bearing wear
• Electrical connections — secure and corrosion-free
• Control board — functioning correctly with no fault codes
Outdoor unit inspection:
• Condenser coil condition — clean or blocked with dirt, debris or salt residue
• Outdoor fan motor operation — running at correct speed
• Compressor — starting correctly, running smoothly, correct operating pressures
• Refrigerant pressure — measured with gauges to confirm correct charge or identify low refrigerant
• Electrical connections — secure, corrosion-free and correctly rated
• Capacitor — correct capacitance, no swelling or leakage
• Reversing valve — operating correctly for heat pump models
After the full inspection your technician will explain exactly what is wrong in plain language — no technical jargon — and provide a full written quote itemising labour, parts and refrigerant gas separately. No work begins until you have read the quote and given your written approval. If you are not happy with the quote you pay only the R350 call-out fee and the technician leaves — no pressure and no obligation.
What happens at this step:
• Full inspection of indoor and outdoor units
• Refrigerant pressure measured with gauges
• All key components tested — compressor, fans, coils, drain, electrical
• Fault explained clearly in plain language
• Full written quote — labour, parts and refrigerant itemised separately
• Honest repair vs replace recommendation if relevant
• No work starts without your written approval
• No obligation to proceed — R350 call-out fee only if you decline
Step 4 — Repair, Service or Regas Completed Using Genuine Parts
Once you approve the quote we get to work immediately. Because our mobile units carry refrigerant gas, cleaning equipment and the most common replacement parts for all major aircon brands — the majority of aircon repairs, services and regasses in Durban are completed in a single visit.

Our Promise on Every Aircon Repair in Durban
Durban’s heat makes a functioning air conditioner essential — not optional. We have been repairing air conditioners across Durban for 22 years because we understand that urgency completely. We carry the gas, the parts and the equipment to fix your aircon in a single visit. We diagnose accurately, quote honestly and repair correctly — with a 6-month guarantee that means something. That is our promise on every aircon repair, service and regas across every suburb in Durban.
1. What is the difference between an inverter and a non-inverter air conditioner and which is cheaper to repair?
Understanding the difference between these two types helps you understand both your electricity costs and your likely repair costs:
Non-inverter air conditioners operate on a simple on-off basis — the compressor runs at full power until the set temperature is reached, switches off completely, then switches back on at full power when the temperature rises again. This constant starting and stopping draws high current at each start-up, consumes more electricity and places more mechanical stress on the compressor over time.
Inverter air conditioners have a variable speed compressor that adjusts its output continuously to maintain the set temperature — running at low speed when the room is nearly cool and only running at high speed when maximum cooling is needed. This results in significantly lower electricity consumption — typically 30 to 50 percent less than a comparable non-inverter unit — smoother temperature control and less mechanical stress on the compressor.
From a repair perspective: • Non-inverter units are generally less expensive to repair — simpler control systems, fewer complex electronic components and widely available parts • Inverter units have more sophisticated control boards and inverter drive boards that are more expensive to replace when they fail • However inverter compressors typically last longer than non-inverter compressors due to the reduced mechanical stress of variable speed operation
Both types are fully repairable by our certified technicians across all Durban areas. WhatsApp us on +27 79 976 2941.
2. How do I calculate the correct aircon size for my room in Durban?
Choosing the correct aircon size — measured in BTU or kW — is critical for both comfort and efficiency. An undersized unit will run constantly without adequately cooling the room. An oversized unit will cool the room too quickly without adequately dehumidifying it — leaving the room feeling cool but clammy. In Durban’s humid climate adequate dehumidification is as important as cooling.
General sizing guide for Durban conditions — add approximately 10 percent to standard calculations to account for Durban’s high ambient temperatures and humidity:
• Up to 15 square metres — 9,000 BTU / 2.6 kW • 15 to 20 square metres — 12,000 BTU / 3.5 kW • 20 to 30 square metres — 18,000 BTU / 5.3 kW • 30 to 40 square metres — 24,000 BTU / 7.0 kW • 40 to 60 square metres — 30,000 BTU / 8.8 kW • 60 to 80 square metres — 36,000 BTU / 10.5 kW
Factors that increase the required capacity in Durban: • South or west-facing rooms with afternoon sun exposure • Rooms with large glass areas or sliding doors • Rooms above ground floor where heat rises • Commercial kitchens or spaces with heat-generating equipment • Poorly insulated ceilings in older Durban homes
Contact us on +27 79 976 2941 for a room assessment and sizing recommendation before purchasing a new aircon unit.
3. What is the difference between R22, R410A and R32 refrigerant and does it matter for my aircon?
The type of refrigerant your aircon uses is important for several reasons:
R22 — also known as Freon — is an older refrigerant that was widely used in air conditioners manufactured before approximately 2010. R22 is being phased out globally due to its ozone-depleting properties and is becoming increasingly expensive and difficult to source in South Africa. If your aircon uses R22 and requires a regas the cost is significantly higher than R410A or R32. An older R22 unit requiring major work is often better replaced with a modern unit.
R410A is the most common refrigerant in air conditioners manufactured between approximately 2010 and 2020. It does not deplete the ozone layer and is widely available in South Africa. Most split air conditioners currently in service in Durban homes use R410A.
R32 is the newest refrigerant used in most modern air conditioners manufactured from approximately 2018 onwards. It has a lower global warming potential than R410A, is more energy efficient and requires a smaller quantity to achieve the same cooling effect. R32 is the direction the industry is moving and is now widely available.
Our mobile units carry all three refrigerant types — R22, R410A and R32 — so we can regas any unit on the same day visit regardless of its age or refrigerant type. To find out which refrigerant your aircon uses check the label on the outdoor unit or the back panel of the indoor unit. WhatsApp us on +27 79 976 2941 if you are unsure.
4. Why does my aircon cool well on mild days but struggle on hot Durban days?
An aircon that cools adequately on mild days but struggles when Durban temperatures peak is showing the classic signs of a unit that is marginally underperforming — often due to one or more of the following:
• Low refrigerant — a unit with slightly low refrigerant may cool adequately under moderate demand but cannot meet the increased cooling load on very hot Durban days. The hotter the day the more the refrigerant deficiency becomes apparent. • Dirty condenser coils — a condenser coil that is partially blocked by dust and salt residue — very common in Durban’s coastal environment — dissipates heat less efficiently. On a mild day this partial blockage may not significantly affect performance. On a 35 degree Durban day the same blockage causes the unit to struggle significantly. • Undersized unit — a unit that is slightly undersized for the room may cope adequately when the ambient temperature is moderate but cannot meet the cooling load when Durban hits peak summer temperatures • Failing compressor — a compressor that is losing efficiency may still function at partial capacity on moderate days but cannot deliver sufficient cooling on very hot days
WhatsApp us on +27 79 976 2941 for a refrigerant level check and service — in many cases resolving one of these issues transforms an aircon that struggles on hot days into one that handles Durban’s worst summer heat comfortably.
5. Can I run my air conditioner during load shedding with a generator or inverter?
Yes — but with important considerations:
Running an aircon on a generator: • The generator must have sufficient capacity to handle the aircon start-up current — which is typically 2 to 3 times the running current. A 9,000 BTU split unit requires a minimum 2.5 kVA generator. An 18,000 BTU unit requires a minimum 4.5 kVA generator. Undersized generators cause voltage fluctuations that damage aircon control boards and compressors. • The generator must produce clean stable power — cheap generators with poor voltage regulation are a leading cause of aircon control board damage • Allow the generator to stabilise for 30 seconds before switching the aircon on
Running an aircon on a home inverter or UPS: • Standard home inverters are generally not powerful enough to run an aircon compressor — the start-up current spike typically exceeds the inverter’s capacity • Some modern high-capacity inverter systems — 5 kVA and above — can run smaller split units. Check your inverter’s specifications against your aircon’s start-up current requirements • Inverter aircon units — not to be confused with inverter power systems — have lower start-up current requirements than non-inverter units and are more likely to be compatible with home inverter power systems

6. How do I clean my aircon filter myself between professional services?
Regular filter cleaning between professional services is one of the most effective things you can do to maintain your aircon’s performance and prevent faults in Durban’s dusty and humid environment. Here is the correct process:
How often: • In Durban’s humid environment we recommend cleaning filters every 4 to 6 weeks during heavy use periods — more frequently if you have pets or live near a dusty road • A filter that is visibly grey or brown when removed is significantly overdue for cleaning
Important — filter cleaning maintains airflow and efficiency but does not clean the evaporator coil, drain pipe or fan blades. A full professional service is still required annually to address these components.
7. Why is my aircon working but not dehumidifying — the room feels cool but damp?
An aircon that cools the air but leaves the room feeling damp and clammy is not dehumidifying effectively. In Durban’s high humidity this is a significant comfort issue. Causes include:
• Oversized unit — an aircon that is too large for the room cools it so quickly that the unit does not run long enough to adequately remove moisture from the air. This is a common consequence of oversizing — the room reaches the set temperature quickly but the air remains humid • Unit set to fan only mode — check that the unit is set to cooling mode and not fan only mode which circulates air without cooling or dehumidifying • Low refrigerant — an aircon with low refrigerant cannot adequately cool the evaporator coil to the temperature required to condense moisture out of the air • Dirty evaporator coil — a coil coated with biological growth — common in Durban’s humid climate — is less effective at condensing moisture from the air • Running on dry or dehumidify mode — some aircons have a specific dry or dehumidify mode that prioritises moisture removal over temperature reduction. This is particularly useful in Durban during humid overcast periods when the temperature is acceptable but humidity is high
WhatsApp us on +27 79 976 2941 if your aircon is not adequately dehumidifying your Durban home or business.
8. What is a split aircon heat pump and how does it work in Durban winters?
Most modern split air conditioners are reverse cycle heat pumps — meaning they can both cool in summer and heat in winter using the same refrigerant system. In cooling mode the unit absorbs heat from inside your home and expels it outside. In heating mode the process is reversed — the unit absorbs heat energy from the outdoor air and transfers it inside to warm the room.
Heat pump heating is significantly more efficient than electric resistance heating — a heat pump produces approximately 3 to 4 units of heat energy for every 1 unit of electrical energy consumed, compared to a 1:1 ratio for a conventional electric heater.
In Durban’s mild winters heat pump heating works very effectively — outdoor temperatures rarely drop low enough to significantly reduce heat pump efficiency. In the rare event of a cold Durban morning where temperatures approach single digits the heat pump may be less efficient than usual but will still provide useful heating.
If your split aircon is not heating in winter the most common causes are a faulty reversing valve, low refrigerant or a control board fault preventing the switch to heating mode. WhatsApp us on +27 79 976 2941 for a same-day diagnosis across Durban.
9. Can salt air from the Durban coast damage my outdoor aircon unit?
Yes — significantly. Salt air is one of the most aggressive environmental factors affecting air conditioning systems in Durban’s coastal suburbs. The specific damage caused by salt air includes:
• Condenser fin corrosion — the aluminium fins on outdoor condenser coils corrode rapidly in salt air, reducing heat dissipation efficiency and eventually causing the fins to disintegrate • Copper tube corrosion — the copper refrigerant tubes connecting the indoor and outdoor units are susceptible to pinhole corrosion from salt air exposure causing refrigerant leaks • Electrical connection corrosion — salt air accelerates corrosion of electrical terminals, connectors and contactors in outdoor units causing electrical faults • Fan motor corrosion — outdoor fan motor housings corrode and bearing seals deteriorate faster in salt air environments • Control board corrosion — in exposed or poorly sealed outdoor units salt air can reach control board components causing corrosion-related electrical faults
Protective measures for coastal Durban aircon units: • Apply anti-corrosion coil coating — a specialist coating applied to the condenser fins that significantly slows salt air corrosion. Ask our technician about this during your next service visit • Annual professional service is particularly important for coastal units — salt residue accumulates on coils and fins and must be cleaned before it causes permanent damage • Position the outdoor unit away from direct sea breeze where the building structure allows • Request marine-grade or coastal-specification units when replacing — several manufacturers offer units with enhanced corrosion protection for coastal installations
10. Why does my aircon trip the electricity only when it is very hot outside?
An aircon that operates normally on mild days but trips the DB board on very hot Durban days is experiencing a high-pressure or high-current fault that only manifests when the unit is under maximum load:
• Dirty condenser coils — on a hot Durban day a condenser coil that is partially blocked by salt residue and dust cannot dissipate heat quickly enough. The refrigerant pressure builds excessively and the high-pressure protection switch trips the unit. On a mild day the same partial blockage does not cause sufficient pressure build-up to trip the protection. • Failing compressor — a compressor that is losing efficiency draws progressively more current as it struggles to maintain pressure. On a mild day it manages. On a 35 degree Durban day it draws excessive current and trips the board. • Low refrigerant causing compressor overheating — a compressor running with low refrigerant overheats — particularly on very hot days when it is already working at maximum capacity. The thermal protection trips to prevent permanent compressor damage. • Undersized wiring or circuit breaker — if the circuit breaker for your aircon is not correctly rated for the unit’s maximum draw it will trip under full load on the hottest days
WhatsApp us on +27 79 976 2941 for a same-day diagnostic visit — this fault type is almost always resolvable without major component replacement if caught early.
11. How long should an air conditioner last in Durban?
The expected lifespan of an air conditioner in Durban depends heavily on maintenance, coastal exposure and load shedding impact:
With regular annual servicing and surge protection: • Non-coastal suburbs — Hillcrest, Westville, Chatsworth, Pinetown — 12 to 15 years • Coastal suburbs — Umhlanga, La Lucia, Bluff, Amanzimtoti — 8 to 12 years due to accelerated salt air corrosion
Without regular servicing and no surge protection: • Non-coastal suburbs — 7 to 10 years • Coastal suburbs — 5 to 8 years
The compressor is the component with the greatest influence on overall lifespan — a well-maintained compressor in a non-coastal Durban suburb can last 15 years or more. A poorly maintained compressor in a coastal suburb exposed to salt air and load shedding may fail in 5 to 7 years.
The most cost-effective approach to maximising aircon lifespan in Durban — annual professional service, dedicated surge protector and switching the unit off at the isolator during load shedding outages.
12. What is the best aircon brand for Durban conditions?
Based on 22 years of repairing air conditioners across Durban these are our observations on the brands that perform best in Durban’s specific conditions:
Brands with consistently strong performance in Durban: • Daikin — widely regarded as the most reliable and durable brand in Durban’s conditions. Parts availability is excellent and the build quality of both indoor and outdoor units is above average. Particularly strong performance in coastal suburbs. • Carrier — strong commercial and residential track record in Durban. Robust outdoor unit construction holds up well against Durban’s coastal conditions. • Mitsubishi Electric — premium build quality with excellent reliability in coastal conditions. Higher purchase price but strong long-term value. • LG — good reliability and very strong parts availability in South Africa. Competitive pricing with above-average performance in Durban conditions.
Brands that perform adequately but require more frequent servicing in Durban: • Midea, Gree, Hisense, TCL — reasonable performance and good value pricing but outdoor unit construction is less robust against Durban’s salt air than the premium brands. More frequent servicing is recommended for coastal installations.
This is not a definitive ranking — individual units of any brand can perform excellently or poorly depending on installation quality, maintenance history and usage patterns. Contact us on +27 79 976 2941 for a recommendation based on your specific Durban suburb and requirements.
13. Can I install an aircon myself in Durban?
Technically possible but strongly not recommended for several important reasons:
• Refrigerant handling requires certification — in South Africa handling refrigerants including R410A and R32 requires certification. Incorrect refrigerant charging — both overcharging and undercharging — permanently damages the compressor within a relatively short operating period • Electrical connection — aircon installation requires a dedicated electrical circuit with correct wiring, isolator switch and circuit breaker. Incorrect electrical installation is a fire risk and will void your insurance • Pipe flaring and brazing — refrigerant pipe connections require correct flaring and brazing techniques. Poor connections cause refrigerant leaks that damage the compressor and require a full system evacuation and recharge • System evacuation — before charging with refrigerant the system must be fully evacuated with a vacuum pump to remove air and moisture. Moisture in the refrigerant system causes acid formation that destroys the compressor from the inside • Warranty — most aircon manufacturers void the product warranty if the unit is not installed by a certified technician

14. Why does my aircon make a gurgling or bubbling sound?
A gurgling or bubbling sound from an air conditioner typically indicates one of two causes:
Refrigerant flow noise — a gurgling or bubbling sound from the indoor unit during normal operation can be the sound of refrigerant flowing through the expansion valve — particularly noticeable when the unit starts or stops. This is normal in many aircon models and not an indication of a fault. If the sound is new or has become louder than before it warrants investigation.
Low refrigerant — when refrigerant levels are low the refrigerant flow becomes irregular — partially liquid and partially gas where it should be entirely liquid. This irregular flow creates a gurgling or bubbling sound particularly in the refrigerant lines between the indoor and outdoor units. If the gurgling sound is accompanied by reduced cooling performance the unit likely has a refrigerant leak and requires a regas after the leak is repaired.
WhatsApp us on +27 79 976 2941 if your aircon is making a gurgling sound that is new or is accompanied by reduced cooling performance. Our technicians can diagnose the exact cause and advise whether a repair is required.
15. How does Durban humidity affect aircon efficiency and what can I do about it?
Durban’s high relative humidity — averaging 70 to 80 percent for much of the year — significantly affects how air conditioning systems perform and what they need to do to create a comfortable indoor environment:
How humidity affects aircon efficiency: • The aircon must remove both heat and moisture from the air — in Durban’s humid climate the moisture removal load is significantly higher than in drier cities, causing the unit to work harder for the same comfort result • High humidity causes more rapid biological growth on evaporator coils — reducing heat exchange efficiency and causing bad smells faster than in drier climates • Condensation management is more critical — drain pipes block faster in Durban’s humid climate as biological growth accumulates more rapidly
What you can do: • Service your aircon more frequently than the standard annual recommendation — every 6 months for Durban coastal properties and annually at minimum for inland Durban suburbs • Run the aircon on dry or dehumidify mode during overcast humid periods — this removes moisture without excessive cooling • Ensure your home or office is adequately sealed when running the aircon — open windows and doors defeat the dehumidification process and force the unit to work continuously • Maintain the condensate drain — a blocked drain in Durban’s humidity causes water damage quickly. Our technicians treat drains with biological inhibitor during every service visit to slow regrowth between services
