Aircon Repairs in Cape Town WC — Cool Again Fast
Not cooling, leaking, making noise, or dead after load shedding? Certified technicians diagnose and fix every type of aircon fault, with a 6-month workmanship warranty and a flat R400 call-out fee.
A Cape Town summer without a working aircon, or a winter night with a heat pump that has stopped heating, is more than an inconvenience. Arnotec Appliance Repairs diagnoses and repairs every type of aircon fault across the city, with certified technicians, genuine OEM parts, and a 6-month workmanship warranty on every job. Below is a full breakdown of the faults we see most often, so you know what to expect before a technician even arrives.
Aircon Problems We Diagnose and Repair
Aircon faults rarely appear without warning. Recognising the early signs below helps you describe the problem accurately when you call, and helps our technician arrive prepared with the right parts.
Aircon Not Cooling or Heating
The unit runs but the air coming out is not cold or hot enough. Usually a refrigerant leak, a dirty condenser coil, a failing compressor, or a faulty reversing valve on heat pump models.
Aircon Not Turning On At All
No response from the remote or wall control. Often a tripped breaker, a blown fuse, a failed capacitor, or in many Cape Town cases, load shedding surge damage to the PCB.
Water Leaking From the Indoor Unit
Water dripping onto walls, floors, or furniture below the indoor unit. Almost always a blocked condensate drain, though a cracked drain pan or a frozen evaporator coil can also cause this.
Ice Forming on the Indoor or Outdoor Unit
A layer of ice on the coil or pipework indicates restricted airflow, low refrigerant, or a dirty filter forcing the system to overwork and freeze up.
Weak or Restricted Airflow
Air barely moving from the vents even when the unit sounds like it is running. Usually a blocked filter, a failing fan motor, or a duct obstruction on ducted systems.
Unusual Noises
Rattling, grinding, clicking, or buzzing sounds from either the indoor or outdoor unit. Loose panels, a failing fan motor bearing, or a struggling compressor are the most common causes.
Bad Smells When the Unit Runs
A musty smell points to mould or bacteria build-up inside the coil or drain pan. A burning smell is more serious and usually means an electrical fault, requiring the unit to be switched off immediately.
Aircon Switching On and Off Repeatedly
Known as short-cycling. Usually caused by a dirty filter, low refrigerant, an oversized unit for the room, or a thermostat sensor fault.
Remote Control or Display Not Responding
The unit itself may be fine, but the remote or digital display fails to communicate. Often a flat battery, a signal receiver fault, or a control board issue.
Refrigerant Leaks
A slow, invisible leak in the pipework or coil that gradually reduces cooling performance. Left unaddressed, it causes the compressor to run harder and eventually fail.
PCB and Control Board Failures
The electronic brain of the aircon unit. A very common fault in Cape Town following load shedding power surges, presenting as erratic behaviour, fault codes, or a completely dead unit.
Compressor Failure
The most expensive fault to repair. The compressor is the heart of the refrigeration cycle, and failure usually results from years of strain, low refrigerant, or electrical damage.
Fan Motor Problems
Both indoor and outdoor units rely on fan motors to move air across the coils. A failing motor causes poor performance, unusual noise, or the unit overheating and shutting down.
Condensate Drain Blockage
Algae, dust, and debris build up inside the drain line over time, causing water to back up and overflow into the room instead of draining outside.
Thermostat and Sensor Faults
A faulty temperature sensor reports incorrect readings to the control board, causing the unit to run at the wrong temperature or cycle unpredictably.
Outdoor Unit Corrosion
Coastal salt air and general weathering corrode the outdoor condenser fins over time, reducing heat exchange efficiency and increasing energy consumption.
High Electricity Bills Without Explanation
A unit working harder than it should, often due to a dirty coil, low refrigerant, or an ageing compressor, quietly increases running costs before the appliance actually fails.
Gas or Refrigerant Overcharge
Sometimes introduced during a poor-quality installation or a previous incorrect top-up, an overcharged system causes high pressure faults and reduced efficiency.
Our Aircon Repair Process
We service and repair all major split-system, ducted, and heat pump aircon brands across Cape Town. Our technicians carry parts and refrigerant for the most common fault types, covering refrigerant top-up and leak detection, PCB and control board replacement, fan motor replacement on both indoor and outdoor units, capacitor replacement, condensate drain clearing and descaling, coil cleaning and disinfection, sensor and thermistor replacement, and reversing valve repairs on heat pump models. This sits under our broader Aircon Services offering across the city.
Aircon Repairs for Cape Town’s Climate and Conditions
Load shedding remains the single biggest cause of aircon PCB failures across Cape Town. Electronic split systems are vulnerable to voltage spikes on power restoration, particularly outdoor unit control boards. If your aircon stopped working or started behaving erratically following a load shedding event, a PCB fault is the most likely cause and is repairable in most cases.
Coastal suburbs experience elevated salt air and humidity that accelerates corrosion on outdoor condenser fins and electrical connections. This causes efficiency losses and intermittent faults over time. We carry out a corrosion check as part of every outdoor unit inspection in coastal areas.
What to Expect When You Call
We respond immediately during business hours, Monday to Saturday, 08:00 to 17:30. Our technician inspects both the indoor and outdoor units, diagnoses the fault, and provides a clear quote before starting. Most aircon repairs are completed in one visit. The call-out fee is a flat R400. We test the unit through a full cooling and heating cycle before leaving and issue the 6-month workmanship warranty on completion.

Aircon Repair Questions
What are the most common aircon problems in Cape Town?
The most frequent faults are units not cooling or heating properly, water leaking from the indoor unit due to a blocked condensate drain, PCB failures from load shedding power surges, weak airflow from a blocked filter or failing fan motor, and unusual noises from a struggling compressor or loose component.
My aircon stopped working after load shedding — is it repairable?
In most cases, yes. PCB failures from power surges are the most common aircon fault we see across the city. We diagnose the affected component and advise on repairability before any work begins.
Why is my aircon leaking water inside?
Water dripping from the indoor unit is almost always a blocked condensate drain. Algae and dust build up inside the drain line over time. A frozen evaporator coil or a cracked drain pan are less common but possible causes.
My aircon smells musty when it runs — what does that mean?
A musty smell indicates mould or bacterial growth inside the coil or drain pan, usually from prolonged moisture exposure. A coil clean and disinfection resolves this in most cases.
What is the call-out fee for aircon repairs?
Our flat call-out fee is R400. This covers the technician’s visit and a full fault diagnosis. A clear, itemised repair quote is provided before any work begins.
What warranty do I get on an aircon repair?
Every repair carries a 6-month workmanship warranty plus OEM parts warranties where applicable. If the same fault returns within that period, we come back at no additional labour charge.
