FAQ
Why is my air conditioner not cooling?
There are several possible causes, including dirty filters, low refrigerant, a faulty compressor, a damaged capacitor, or electrical issues. Our technicians will inspect the unit and identify the exact cause before recommending a repair.
Why is my air conditioner leaking water?
Water leakage is commonly caused by a clogged drainage pipe, frozen evaporator coil, damaged drain pan, or improper installation. Our team can diagnose and fix the issue quickly.
Why is my air conditioner making loud noises?
Unusual noises may be caused by loose components, worn bearings, a faulty fan motor, or compressor problems. It’s best to have the unit inspected before the issue becomes more serious.
Why does my air conditioner have a bad smell?
Bad odours are often caused by mould, bacteria, clogged drainage, or accumulated dirt inside the unit. Depending on the condition, cleaning or repair may be required.
How often should I service my air conditioner?
For residential units, we recommend servicing every 3–4 months. If you use your air conditioner daily, servicing every 2–3 months helps maintain cooling performance and prevent breakdowns.
What is the difference between normal servicing and chemical overhaul?
Normal servicing removes dust and light dirt from the unit. A chemical overhaul involves dismantling the indoor unit and thoroughly cleaning the internal components with chemical solution to remove stubborn dirt, mould, and bacteria, restoring cooling efficiency.
Do you provide emergency repair services?
Yes. We provide prompt troubleshooting and repair services. Same-day appointments may be available depending on our schedule.
