Why Is My Aircon Not Cold?
An air conditioner that runs but doesn't cool is the most common complaint we hear in KL's heat — and in most cases it's fixable the same day. The unit blowing warm air doesn't mean it's dead: nine times out of ten the cause is dirt, low refrigerant gas, or a single failed component.
The wrong move is to keep running it. A struggling unit works harder, burns more electricity, and can turn a small fault into a compressor-level repair. The right move is a proper diagnosis — our technicians check the whole cooling circuit and give you a fixed quote before any work begins.
Common Causes of an Aircon Not Cooling
- Dirty filter or clogged evaporator coil — airflow is blocked, so the room never cools. Fixed with a chemical clean.
- Low refrigerant gas — the unit blows air at room temperature. Needs a leak check and gas top-up.
- Refrigerant leak — gas keeps dropping after every top-up. The leak must be found and sealed first.
- Dirty outdoor condenser — heat can't escape, so cooling capacity collapses on hot afternoons.
- Failing capacitor or fan motor — the compressor or fan can't run at full power.
- Wrong-sized unit — an undersized aircon can't cool the room no matter how clean it is.
- Thermostat or sensor fault — the unit thinks the room is already cold and idles.

“service is good, everything is properly explained and before top up gas, they check with us first. they helped to fix the leak from installation time apparently. so all good 👍. price was a little unexpected due to the gas, Premium Chemical cleaning = RM150 for 1 unit of 1.5HP aircon + RM 100 for gas top up (70 PSI) but for a total of RM250 include fixing the gas leak I'd say its worth the price.”

“This is my 4th time doing aircond service with the company. Communication is smooth and professional. The price is fixed and there is no hidden price or hard sell. I did trouble shooting and aircond service at RM150. This includes their fees coming to your condo. Other company make this as their additional fees.”

FAQ
Aircon Not Cold — Your Questions Answered
My aircon is blowing air but it's not cold — what's wrong?
Most often it's a dirty coil restricting airflow or low refrigerant gas. Both are same-visit fixes: a chemical clean from RM125 or a gas top-up from RM150. Our technician diagnoses the exact cause first, from RM88.
How fast can you come if my aircon is not cooling?
Same-day slots are available across KL & Selangor on most days. WhatsApp 018-400 6624 in the morning and we can usually be there the same afternoon.
Should I just top up gas if the aircon is not cold?
Not blindly. If gas is low, it leaked from somewhere — topping up without checking means the problem returns in weeks. We check for leaks first and quote you honestly.
How much does it cost to fix an aircon that is not cooling?
Diagnosis is from RM88. Most fixes land between RM125 (chemical clean) and RM400 (leak repair with top-up). You approve a fixed quote before any work starts.
