Why is my aircon working but not dehumidifying and the room feels cool but damp?

An aircon that cools but does not dehumidify properly may be oversized for the room, set to fan mode instead of cooling mode, low on refrigerant or have a dirty evaporator coil. In Durban's humid climate, poor dehumidification makes a room feel clammy even when the temperature is lower. Some units also have a dry or dehumidify mode that works better during humid periods.

Q: What is the difference between an inverter and a non-inverter air conditioner and which is cheaper to repair?

Non-inverter air conditioners run on a simple on-off cycle, with the compressor switching fully on and off to maintain temperature. This uses more electricity and creates more mechanical stress over time. Inverter air conditioners use a variable-speed compressor that adjusts output continuously, reducing electricity use and improving temperature stability. From a repair point of view, non-inverter units are usually cheaper to repair because they have simpler control systems and fewer complex electronic parts. Inverter units often have more advanced boards and inverter drive components that cost more to replace, although their compressors can last longer because they operate more smoothly.

Q: How do I calculate the correct aircon size for my room in Durban?

Choosing the correct aircon size is important for both comfort and efficiency. As a general guide for Durban conditions, rooms up to 15 square metres usually need 9000 BTU or 2.6 kW, 15 to 20 square metres need 12000 BTU or 3.5 kW, 20 to 30 square metres need 18000 BTU or 5.3 kW, 30 to 40 square metres need 24000 BTU or 7.0 kW, 40 to 60 square metres need 30000 BTU or 8.8 kW, and 60 to 80 square metres need 36000 BTU or 10.5 kW. In Durban, it is wise to add around 10 percent for heat and humidity. Room orientation, glass area, heat-generating equipment and poor insulation can also increase the required capacity.

Q: What is the difference between R22, R410A and R32 refrigerant and does it matter for my aircon?

Yes, the refrigerant type matters. R22 is an older refrigerant used mainly in air conditioners made before about 2010 and is becoming harder and more expensive to source because it is being phased out. R410A is common in units made roughly between 2010 and 2020 and is widely available. R32 is used in many newer air conditioners, is more energy efficient and has a lower environmental impact than R410A. The refrigerant type affects service cost, parts availability and whether it is worthwhile repairing an older unit.

Q: Why does my aircon cool well on mild days but struggle on hot Durban days?

This usually points to a system that is underperforming but not completely failed. Common causes include slightly low refrigerant, dirty condenser coils, an undersized unit or a compressor that is losing efficiency. On mild days the aircon may still cope, but on very hot Durban days the extra cooling load makes the problem much more noticeable.

Q: Can I run my air conditioner during load shedding with a generator or inverter?

Yes, but only if the backup power system is correctly sized and produces stable power. A generator must handle the high start-up current of the compressor and should have good voltage regulation. Standard home inverters are usually not powerful enough for most aircon compressors, although larger inverter systems may run smaller split units. Inverter air conditioners often have lower start-up current than non-inverter units and may be more compatible with larger backup systems.

Q: How do I clean my aircon filter myself between professional services?

Switch the aircon off at both the unit and wall isolator. Open the front panel, remove the filter panels, take them outside, tap off loose dust, then wash them with lukewarm water and mild detergent. Rinse well and let them dry completely in the shade before refitting. In Durban, filters should generally be cleaned every 4 to 6 weeks during heavy use, and more often if you have pets or live near dust. This helps airflow and efficiency, but it does not replace a full professional service.

Q: 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, which means they can both cool in summer and heat in winter using the same refrigerant system. In cooling mode they move heat from indoors to outdoors. In heating mode they reverse the process and move heat from outdoor air into the room. This is very efficient, especially in Durban's mild winters where outdoor temperatures usually remain suitable for heat pump operation.

Q: Can salt air from the Durban coast damage my outdoor aircon unit?

Yes. Salt air can significantly damage outdoor aircon units in coastal Durban areas. It accelerates corrosion of condenser fins, copper tubes, electrical terminals, fan motor components and even control boards if the outdoor unit is not well protected. Protective measures include regular servicing, anti-corrosion coatings, careful placement and choosing coastal-specification units when replacing older systems.

Q: Why does my aircon trip the electricity only when it is very hot outside?

This usually means the unit develops a high-pressure or high-current fault only under maximum heat load. Common causes include dirty condenser coils, a compressor that is losing efficiency, low refrigerant causing compressor overheating or wiring and breaker problems. On mild days the unit may cope, but on very hot Durban days the extra stress triggers the trip.

How We Repair Your Air Conditioner — The Appliance Repairs Durban Process

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:

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

Frequently Asked Questions — Air Conditioning Repairs 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

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:

Switch the aircon off at the unit and at the wall isolator switch
Open the front panel of the indoor unit — this usually snaps open or lifts off. Consult your manual if you are unsure
Remove the filter panels — they typically slide or lift out
Take the filters outside and tap them gently to dislodge loose dust
Wash with lukewarm water and a small amount of mild detergent — do not use hot water or harsh chemicals
Rinse thoroughly and allow to dry completely in the shade — never in direct sunlight as this can warp plastic filter frames
Refit the dry filters, close the panel and switch the aircon back on

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

Contact us on +27 79 976 2941 for a supply and installation quote. Our certified technicians install all major aircon brands across all Durban areas to the correct South African electrical and refrigeration standards.

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
