Aircon Servicing & Repair in Alor Setar

A musty smell means mould or bacteria on the evaporator coil or in the drain pan — fixed with a chemical wash. A burning smell can be dust on a heater element or a failing motor and is worth an inspection. A vinegar-like or chemical smell can indicate a refrigerant leak; turn the unit off and call a technician.

Pricing depends on the service depth: a basic clean-and-check per unit is the cheapest, a chemical wash costs roughly double, and a full overhaul double again. Multi-unit discounts are standard.

Once a year is the minimum for a system used seasonally; every 3-4 months if you run it daily in a hot climate. Regular servicing keeps coils and filters clean, which protects the compressor — the most expensive part to replace — and keeps energy use down.

A standard clean-and-check takes 30-45 minutes per indoor unit. A chemical wash takes about an hour per unit, and a full chemical overhaul (where the unit is dismantled) takes 1.5-2 hours per unit. Multi-unit visits are faster per unit.

You can safely wash or replace filters monthly, keep the outdoor unit clear of leaves and debris, and wipe the indoor casing. Anything involving the refrigerant circuit, electrical components, or coil chemicals should be left to a certified technician — refrigerant handling is legally restricted in most countries.

Most charge a call-out or diagnostic fee that covers travel and the first inspection; many waive or credit it against the repair if you go ahead. Confirm the fee, whether it is credited, and any surcharge for evenings, weekends, or urgent same-day visits before the technician is dispatched.

Normal service is RM50-RM90 per unit (bundles cheaper per unit), chemical wash RM130-RM200 per unit, and chemical overhaul RM250-RM400 per unit. Gas top-up, when genuinely needed, adds RM50-RM150 for R32/R410A depending on amount.

Every 3 months for daily-use bedrooms and living rooms; haze season (usually mid-year) clogs filters faster, so check filters monthly during haze episodes. A chemical wash every 12-18 months keeps cooling strong in Malaysian humidity.
