How much does an aircon chemical wash cost in Klang?

Prices vary by unit type and horsepower. As a rough guide, a basic service for a wall-mounted split unit is often around RM50 to RM100 per unit, and a chemical wash is commonly RM120 to RM250 per unit. Ceiling cassette and larger units cost more. Gas top-ups and repairs are usually extra, so confirm the quote first.

How often should I service my aircon?

A general service every 3 to 6 months suits most homes. Heavy use, pets, cooking fumes or a dusty roadside location call for the shorter interval. A chemical wash is usually needed once a year, or sooner if you notice smells, weak cooling or water leaks.

What should I expect during a chemical wash?

Expect about 45 minutes to 1.5 hours per unit. The technician covers the unit, applies cleaner to the coil, rinses it, cleans the drain and filters, then reassembles and tests it. The area should be left tidy, and the unit should cool better and smell fresher afterwards.

How can I tell if the service was done properly?

Check for clean dust-free filters, water draining freely from the outlet pipe, no leftover foam or dirty water on the floor, stronger airflow, and a cooler air temperature within a few minutes. A good contractor will explain any issues found, rather than pushing unneeded parts.

Aircon servicing and chemical wash in Klang

A routine service cleans the filters, indoor coil, drain tray and blower with water and low-pressure spray, then checks gas pressure and airflow. A chemical wash goes further. The technician covers the wall unit, applies a coil cleaner, and rinses out the grime. For split units, the outdoor condenser is often washed too. It suits systems that smell musty, drip water, or cool poorly even though the gas level is fine.

In Klang's humid climate, mould builds up quickly on the indoor coil and drain line. So the difference between a rushed job and a proper one shows up fast.

When comparing the 27 businesses listed here, look for:
