Professional Aircon Not Cooling Service in Stellenbosch

Same Symptom, Very Different Repairs

"Not cooling" is the most common aircon call we get in Stellenbosch, and it is also the one most often misdiagnosed. Low refrigerant, a clogged filter, a failed run capacitor, a dirty condenser coil, a faulty thermostat or sensor, and a failing compressor all produce exactly the same complaint — warm air from a unit that sounds like it is working. Our Stellenbosch aircon team measures before it quotes.

How We Find the Actual Fault

The technician checks the temperature split across the indoor coil, reads the suction and discharge pressures, tests the capacitor and contactor, and inspects the coils and filters. Fault finding costs R580 and takes about half an hour. It tells us whether you are looking at a clean, a capacitor, a regas, or a compressor replacement that is often not worth doing on an older unit. If the repair comes to more than R1,000 we waive the call-out, so you only pay for the work.

The Cheap Checks Worth Doing First

Before you call anyone: pull the indoor filters and look at them — a filter thick with dust chokes the airflow and is the single most common cause. Check that the outdoor unit is not boxed in by a wall, plants or a new fence, and that nothing has been built over it. Make sure the remote is on cool and not fan-only. If all of that is clear, the fault is inside the system and needs a technician.

We provide fast, professional Air Conditioning & HVAC in Stellenbosch services, helping you fix aircon not cooling issues. Stellenbosch properties span Cape Dutch heritage homes, modern wine-estate residences and Technopark commercial spaces, so installation work benefits from contractors comfortable across a wide build mix.

How to Tell What's Wrong With Your Aircon in Stellenbosch

The signs you notice at home can help determine how serious the issue is and how quickly a air-conditioning professional should attend.

What you may notice

  • Weak airflow from the indoor unit
  • Filters visibly grey with dust
  • Musty smell when it starts up

This usually indicates:
Blocked filters and a dirty evaporator coil choking the airflow

Recommended action:
Book a service and coil clean — usually restores full cooling

What you may notice

  • Indoor fan runs but the outdoor unit never starts
  • Humming or clicking from the outdoor unit
  • Outdoor fan blade will spin if nudged

This usually indicates:
Failed run capacitor or contactor — a common and inexpensive repair

Urgency: Medium

Recommended action:
Get the capacitor tested before assuming the compressor has failed

What you may notice

  • Trips the breaker when the outdoor unit tries to start
  • Loud grinding or screeching from outside
  • Unit is more than ten years old

This usually indicates:
Compressor failure — often not economical to repair on an older unit

Get an honest repair-versus-replace assessment before spending

Frequently Asked Questions

Why is my aircon running but not cooling?

The most common causes are blocked filters or a dirty evaporator coil choking the airflow, low refrigerant from a leak, a failed run capacitor stopping the outdoor compressor, a fouled condenser coil, or a faulty thermostat or sensor. They all present identically, which is why a proper diagnosis comes before any quote.

What can I check myself before calling?

Three things worth doing first: pull the indoor filters and see whether they are thick with dust, check that the outdoor unit is not boxed in by plants, a wall or new building work, and make sure the remote is set to cool rather than fan-only. If all three are fine, the fault is inside the system.

How long does a diagnosis take?

About half an hour, and it costs R580. The technician checks the temperature split across the indoor coil, reads the suction and discharge pressures, tests the capacitor and contactor, and inspects the coils and filters. That is enough to tell you whether you are facing a clean, a capacitor, a regas or a compressor. If the repair comes to more than R1,000 we waive the call-out fee.

Is it worth repairing an old aircon that stopped cooling?

It depends on the fault and the age. A capacitor or a coil clean is always worth doing. A compressor replacement on a unit over ten years old, especially one running the old R22 refrigerant, usually is not — the repair often costs a large share of a new inverter unit that will use considerably less electricity. We will tell you plainly which situation you are in.

Can you come out the same day?

In most cases yes, across Paarl, Stellenbosch, Somerset West and the surrounding towns. Demand spikes during the first hot week of summer, when everybody discovers their aircon at the same time — booking a service in early spring avoids that queue entirely.
