Centurion experiences extreme heat in summer and sharp cold during winter nights. A functioning air conditioner is not a luxury in this climate — it is a practical necessity for comfortable living and productive working. When an air conditioner stops cooling in January or fails to heat in June, you need a qualified local technician who can respond the same day, not someone navigating in from Johannesburg or Pretoria East.
Centurion Appliance Repairs provides professional air conditioner repairs and installation services in Centurion for residential and commercial clients across all suburbs. Our certified technicians carry the refrigerants, diagnostic equipment, and most commonly needed air conditioner components in their service vehicles. We repair split units, inverter systems, multi-split systems, cassette units, and ducted air conditioning systems across all major brands.
We also install new air conditioning systems — from single-room split units in homes in Eldoraigne and Wierda Park to multi-room commercial systems in office parks in Highveld and Sunderland Ridge.
Our office is in Die Hoewes, Centurion. Our 35 mobile technicians are positioned across Centurion daily. We are a genuine local operation, not an out-of-area company operating Centurion as a secondary territory.

An air conditioner that runs — the fan blows, the unit starts — but fails to produce cold air is the most common fault we attend across Centurion, particularly during the summer months. It is also the most frequently misunderstood, because the fault can originate from several different components and requires accurate diagnosis before any repair is recommended.
A low refrigerant charge is the most common cause. Unlike a car tyre that goes flat from a puncture in a single event, refrigerant loss from an air conditioner is typically gradual — caused by a small leak in the refrigerant circuit that depletes the charge over months or years. As the charge drops, the system’s ability to absorb heat from the room decreases progressively, until eventually the unit blows room-temperature air while appearing to run normally. Symptoms include reduced cooling performance that has worsened over time, ice forming on the indoor unit’s pipework, and a hissing sound near the pipes in some cases.
A refrigerant recharge without locating and repairing the leak is a temporary fix. The refrigerant will escape through the same leak point and the unit will be low again within months. Our technicians check for leaks before recommending a recharge, locate the source using electronic leak detection equipment, repair the leak, and then recharge to the correct specification. We carry R410A and R32 refrigerants — the two most common refrigerants in current split unit systems — in our service vehicles.
Dirty or fouled condenser coils on the outdoor unit are one of the most overlooked causes of poor cooling. The outdoor unit’s condenser coil rejects heat from the refrigerant circuit into the outside air. When the fins are coated in dust, pollen, cottonwood, and organic debris — which accumulates rapidly in Centurion’s dry, dusty conditions — heat cannot be rejected effectively. The condensing temperature rises, the compressor works against higher pressure, and the unit’s cooling capacity drops significantly. Condenser coil cleaning as part of a service visit can restore cooling performance that has been declining for years without any mechanical fault being present.
A failing or failed compressor is the most serious cause of an air conditioner not cooling. The compressor circulates the refrigerant through the system under pressure. When it fails — through electrical winding failure, mechanical seizure, or capacitor failure that prevents starting — the refrigerant cannot circulate and no cooling occurs. Compressor diagnosis requires pressure testing and electrical measurement. A compressor that is producing abnormally low pressures may be recoverable with a hard start kit in some cases. A compressor that has failed mechanically requires replacement.
A failed indoor unit fan motor means room air is not being drawn across the evaporator coil, so even when the refrigeration circuit is functioning correctly, very little cooled air is delivered to the room. This is typically identified by the indoor unit running but producing minimal airflow.
South African households often overlook their air conditioner’s heat pump function until a cold Centurion winter night reveals that the unit has stopped heating. A reverse-cycle air conditioner uses the same refrigerant circuit to provide both cooling and heating — switching between modes using a reversing valve. Faults specific to the heating mode include a failed reversing valve that is stuck in cooling mode, refrigerant shortage, or an outdoor unit that is not able to absorb sufficient heat from cold outside air.
On some systems, an outdoor unit that is heavily iced — which can occur when the unit is trying to heat in cold, humid conditions — prevents heat extraction. Modern units have an automatic defrost cycle that should address this. If the defrost cycle is not operating correctly, the unit progressively loses heating performance as ice builds up. A defrost system fault is diagnosed through the unit’s error code output and operational testing.
Water dripping from the indoor unit onto the wall or floor below is one of the most common complaints we receive from Centurion homeowners, particularly in summer when the unit is running continuously. The cause is almost always a blocked condensate drain line.
During cooling operation, the indoor unit’s evaporator coil cools warm, humid room air below its dew point. Moisture condenses on the coil and drips into a drain tray, from which it flows through a drain pipe to the outside. When this drain pipe becomes blocked — typically with algae, mould, or debris — water backs up in the tray until it overflows into the room.
Clearing the condensate drain line is a standard service task that our technicians perform during maintenance visits and as a repair call-out when active leaking is reported. It is a preventable fault — the drain line should be checked and cleared as part of annual servicing.
A secondary cause of indoor unit water leakage is ice forming on the evaporator coil. Ice indicates low refrigerant charge or severely restricted airflow through the indoor unit. When the unit is switched off or the compressor cycles off, the accumulated ice melts and drips from the indoor unit. If you notice ice on the pipes going into or out of the indoor unit, or the unit is producing very little airflow, this is the likely cause.
Water dripping from the outdoor unit is normal during cooling operation — this is condensate that has been pumped out through the drain line and is not a fault. However, significant amounts of water pooling under the outdoor unit, or water leaking from the refrigerant pipe connections, may indicate a condensate drain issue or in some cases a refrigerant leak point. If you are unsure whether what you are seeing is normal condensate or a fault, call us and describe what you are observing.
An air conditioner that appears to be functioning — blowing cold air from the vents — but not actually reducing the room temperature to the set point despite running for extended periods is a common complaint that is often misattributed to the unit being undersized.
Dirty air filters are the most common and most easily resolved cause. The indoor unit’s air filter captures dust and debris from room air. When it becomes blocked, airflow through the indoor unit drops significantly, reducing the volume of air that is cooled and delivered to the room. Most residential air conditioner filters should be cleaned every two to four weeks during periods of heavy use. Our technicians clean filters as part of every service visit and show clients how to do it themselves between visits.
A unit that was correctly sized for a room that has since been expanded — through removal of a partition wall, conversion of an adjacent space, or addition of significant heat-generating equipment — may genuinely be undersized for its current application. We assess room requirements honestly and advise on whether the existing unit is adequate or whether an upgrade is warranted.
Heat infiltration from poor building envelope — single-glazed windows, no ceiling insulation, an east or west-facing room without curtains or blinds — significantly increases the cooling load on the unit. We can advise on practical steps to reduce heat infiltration that will improve the unit’s ability to maintain the set temperature.
A grinding or scraping noise from the outdoor unit — particularly at start-up or under load — indicates fan blade damage, fan motor bearing wear, or in serious cases, debris trapped inside the outdoor unit case. Tree seeds, leaves, and small branches from Centurion’s abundant vegetation regularly enter outdoor units. The outdoor unit should be kept clear of plant growth, and the area around it should be kept clean.
A rattling noise from the outdoor unit when it starts or stops — particularly on inverter units that vary their speed — is often caused by a loose panel, a loose refrigerant line bracket, or a compressor that is vibrating more than normal due to mounting pad deterioration. Persistent rattling should be investigated rather than ignored.
A squealing noise from the indoor unit during operation indicates a fan motor that is beginning to fail. This is a progressive fault — addressing it at the early-noise stage is significantly less expensive than a complete motor replacement after seizure.
A clicking sound at regular intervals that is not associated with normal compressor cycling is often a relay or capacitor that is failing to hold a consistent electrical connection.
A unit that shows no response — no display lights, no fan, no compressor — requires systematic electrical diagnosis. Common causes in Centurion include a tripped circuit breaker (load shedding voltage spikes cause outdoor unit circuit breakers to trip more frequently than they should), a blown internal fuse, a failed control board, a failed outdoor unit contactor, or a remote control that is no longer communicating with the indoor unit.
Load shedding in Centurion has been a significant cause of air conditioner control board failures. The voltage spikes that occur when Eskom power is restored after an outage can damage the PCB of both the indoor and outdoor units. If your air conditioner stopped working after a power outage and will not restart, the control board has likely been affected. We diagnose and replace control boards for all major brands.
Modern air conditioners display error codes when faults are detected in the system. These codes guide diagnosis but must be interpreted in conjunction with on-site testing — the same error code can result from different faults on different units.
Samsung air conditioners display error codes on the indoor unit display including E1 or CH07 for indoor temperature sensor faults, E2 or CH08 for outdoor temperature sensor faults, E4 or CH04 for communication errors between indoor and outdoor units, and E5 or CH05 for inverter compressor protection trips.
LG air conditioners display codes including CH02 for outdoor temperature sensor faults, CH07 for indoor heat exchanger sensor faults, CH10 for DC fan motor faults, and CH38 for inverter IPM module faults on inverter models.
Daikin units use U4 codes for communication errors, A6 for outdoor fan motor faults, L4 for radiant heat sensor trips, and UF for phase current abnormality on inverter compressors.
Midea and AUX units — common in Centurion’s mid-range residential installations — use E1 through E9 codes for various sensor, communication, and protection faults.
If your unit is displaying a code not listed here, call us with the brand, model, and code displayed. We will advise on the most likely cause before the visit.
A musty smell from the indoor unit is caused by mould and bacterial growth on the evaporator coil, in the drain tray, and on the air filter. This is a hygiene issue as well as a performance issue — the unit is circulating mould spores throughout the room. A chemical wash of the indoor unit, combined with drain line cleaning and filter replacement, addresses this completely. We recommend chemical cleaning every 12 to 18 months for residential units and every 6 to 12 months for commercial units in Centurion.
A burning smell when the unit starts — which disappears after a few minutes — is often dust burning off the coils after a period of inactivity. This is normal after the unit has not been used for several months. If the burning smell is persistent or accompanied by visible smoke, switch the unit off immediately and contact us.
A sweet, ether-like smell near the outdoor unit or the refrigerant pipes may indicate a refrigerant leak. Refrigerant has a distinctive chemical odour. Contact us if you suspect a refrigerant leak.
Split-unit air conditioners (wall-mounted) The most common type in Centurion homes and offices. We repair and install split units from all major brands in back-to-back and extended pipe run configurations. Standard installations include all refrigerant pipework, drainage, electrical connection, and commissioning.
Inverter air conditioners Inverter technology uses a variable-speed compressor that adjusts output to match the cooling or heating load — more energy efficient and quieter than fixed-speed systems. Inverter faults have a specific diagnostic profile involving the inverter drive board, IPM module, and compressor current sensing. Our technicians are experienced with inverter technology across all major brands.
Multi-split systems One outdoor unit connected to multiple indoor units, each serving a different room or space. Multi-split systems are common in Centurion’s larger homes and commercial offices where individual room temperature control is needed without the complexity of a ducted system. We repair and install multi-split systems from brands including Samsung, LG, Daikin, Midea, and Gree.
Cassette units Ceiling-mounted cassette air conditioners for commercial environments — offices, retail spaces, restaurants, and conference rooms. They offer 360-degree airflow distribution from a central ceiling position. We repair and install cassette units for commercial clients throughout Centurion.
Ducted air conditioning systems Central air conditioning systems that condition all rooms through a network of ducts from a central air handler. Common in larger residential properties and commercial buildings. We service ducted systems for both residential and commercial clients across Centurion.
Floor-console units Floor-standing indoor units suitable for rooms where wall mounting is not feasible. We repair and install floor console units for residential and commercial applications.
Portable units Mobile air conditioners that require no permanent installation. We repair portable units for clients who cannot accommodate a permanent installation.
We repair and install all major air conditioner brands sold in South Africa, including:
Samsung | LG | Daikin | Midea | AUX | Gree | Carrier | Hitachi | Fujitsu | Panasonic | York | Bosch | Toshiba | Mitsubishi Electric | Alliance | Jet-Air | TCL | Hisense | Haier | Whirlpool
Samsung and LG are the most widely installed residential air conditioner brands in Centurion. We maintain a comprehensive parts inventory for both. Daikin is the dominant premium brand in commercial and high-end residential installations in Centurion — we carry Daikin-specific technical knowledge and source Daikin-approved parts through our supply network. Midea and AUX are common in mid-range installations and we are well-stocked for both.
If your brand is not listed, call us on 079 976 2941 — in most cases we can assist.
We install new air conditioning systems throughout Centurion for homeowners, landlords, property developers, and businesses. Our installation service covers:
Unit selection and sizing We assess your room dimensions, heat load, insulation quality, window orientation, and occupancy patterns to recommend the correct unit capacity. Under-sizing an air conditioner is the most common installation mistake — a unit that is too small for the space runs continuously without reaching the set temperature and wears out prematurely. Over-sizing wastes capital and produces humidity problems. We size correctly from the start.
Supply of units We supply leading air conditioner brands at competitive prices. You can also supply your own unit and we will install it. Where we supply the unit, installation is streamlined as we work with the unit from the start.
Standard back-to-back installation Indoor unit on one wall with the outdoor unit mounted directly behind it on the outside, with minimal pipe run. This is the most cost-effective installation configuration for most residential bedrooms and home offices.
Extended pipe run installations Where the outdoor unit cannot be located directly behind the indoor unit — common in apartments, multi-storey buildings, and commercial spaces — we manage the pipe run, trunking, and drainage over longer distances.
Commercial installations Multi-split systems, cassette units, and ducted systems for offices, retail spaces, restaurants, medical practices, and commercial facilities throughout Centurion. We manage the full installation from site survey through to commissioning.
Post-installation service All our installations are commissioned and tested before handover. We register the warranty with the manufacturer where applicable and brief the client on filter cleaning, correct usage, and recommended servicing intervals.
Regular servicing is the most effective way to maintain air conditioner performance, extend the unit’s lifespan, and prevent breakdowns. We recommend servicing residential units at least once a year and commercial units every six months. Our service visit includes:
Cleaning of the indoor unit’s air filter. Chemical cleaning of the indoor unit’s evaporator coil to remove mould, bacteria, and mineral deposits. Clearing of the condensate drain line. Cleaning of the outdoor unit’s condenser coil. Checking and tightening of electrical connections. Refrigerant pressure measurement and charge assessment. Fan motor current measurement and condition assessment. Full operational testing in cooling and heating modes.

Complete supply and install pricing depends on the brand, model, and BTU capacity of the chosen unit. A quality 9 000 BTU inverter split unit supplied and installed in Centurion typically costs R9 500 to R13 000 including the unit. A 12 000 BTU unit costs R11 000 to R15 000 supplied and installed. An 18 000 BTU unit for a larger room or open plan space typically costs R14 000 to R20 000 supplied and installed.
Contact us for a specific supply and install quotation for your requirements.
BTU sizing is critical. The most common mistake in air conditioner selection is buying a unit that is too small for the space. As a rough guide: a 9 000 BTU unit suits a room of approximately 15 to 20 square metres with standard insulation. A 12 000 BTU unit suits 20 to 30 square metres. An 18 000 BTU unit suits 30 to 45 square metres. An open-plan living area with high ceilings or large windows facing west will need more capacity than these figures suggest. We assess your specific space before recommending a capacity.
Inverter versus fixed-speed. Inverter air conditioners adjust their compressor speed to match the required cooling or heating load — they are quieter, more energy efficient, and heat or cool the room more consistently than fixed-speed units. The higher purchase price is typically recovered in electricity savings within two to three years of regular use. In Centurion’s electricity price environment, inverter technology is almost always the better choice for any unit that will be used regularly.
Load shedding compatibility. If you want to run your air conditioner during load shedding on a generator or UPS, the electrical specifications of the unit and your backup power source must be compatible. Most residential split units require a stable 220V 50Hz supply and are sensitive to voltage variations. We can advise on compatibility and surge protection requirements before installation.

My aircon is blowing air but not cooling the room — is it low on gas? Low refrigerant charge is the most common cause, but it is not the only cause. Dirty condenser coils, a restricted indoor filter, or a failing compressor can produce similar symptoms. We diagnose accurately before recommending a recharge — a recharge on a system with a blockage or compressor fault will not restore cooling and is a wasted cost. Call us and we will confirm the specific cause on-site.
Do you recharge aircon gas on-site in Centurion? Yes. We carry R410A and R32 refrigerants in our service vehicles and carry out gas recharges on-site as part of the same visit where the leak has been located and repaired. We do not recharge without first checking for a leak — a recharge on an unrepaired leaking system is a temporary fix at best.
My Samsung aircon stopped working after load shedding — what is wrong? Load shedding voltage spikes are a common cause of air conditioner control board damage in Centurion. If your unit has a blank display, shows a new error code that was not present before the outage, or simply does not respond to the remote, the indoor or outdoor PCB has likely been affected. We diagnose and replace control boards for Samsung, LG, Daikin, Midea, and all other brands. We strongly recommend installing a surge protector on your air conditioner’s circuit.
Can you install a new air conditioner at my home in Centurion? Yes. We install new split units, multi-split systems, cassette units, and ducted systems throughout Centurion. We can supply the unit or install a unit you have purchased. Contact us for a site assessment and quotation.
What size air conditioner do I need for my room? As a starting guide: 9 000 BTU for a standard bedroom of 15 to 20 square metres, 12 000 BTU for a larger bedroom or small open-plan space of 20 to 30 square metres, and 18 000 BTU for a larger lounge or open-plan area. However, ceiling height, insulation quality, window size and orientation, and the number of occupants all affect the correct sizing. We carry out a proper assessment before recommending a capacity.
How often should I service my air conditioner? Residential units should be serviced at least once a year. Commercial units that run frequently benefit from servicing every six months. The most important maintenance action between professional services is cleaning the indoor unit’s air filter every two to four weeks during periods of heavy use.
Is it worth repairing an older air conditioner? It depends on the age of the unit, the nature of the fault, and the cost of repair relative to a new unit. A 5 or 7-year-old unit requiring a gas recharge or fan motor replacement is absolutely worth repairing. A 12 or 15-year-old unit requiring compressor replacement may be approaching the end of its useful life, and the repair cost versus a new inverter unit — which will use significantly less electricity — warrants comparison. Our technicians give you an honest assessment.
Do you repair and install commercial air conditioners in Centurion? Yes. We repair and install commercial split units, multi-split systems, cassette units, and ducted systems for offices, retail spaces, restaurants, medical practices, and commercial facilities throughout Centurion. Commercial AC repairs are treated as priority callouts where operational continuity is at stake.
