Mavis Eco Cool is a Kuala Lumpur-based aircond service company that has been quietly servicing landed homes, condos, shoplots and offices across the Klang Valley for over a decade. We do not run a high-volume call-centre — every WhatsApp message lands in the hands of someone who actually owns a screwdriver. That is the difference Malaysian customers notice.

Common Aircond Problems We Fix
Most KL and Selangor customers reach us because their aircond is doing one of these six things. We diagnose, quote, and fix in one visit.
Aircond not cold
Three common causes: dirty coil blocking airflow (chemical wash fix), low refrigerant gas (leak check + refill), or failed compressor (diagnose first, then repair).
Aircond leaking water
Almost always a clogged drain pan or sagging drain pipe gradient. Chemical wash flushes the line; we re-pitch the drain in the same visit.
Aircond noisy
Bearing wear, loose blower, fan-blade dust load, or a failing outdoor compressor. We isolate the source on the first call.
Weak airflow
Filter and coil dirt is the #1 cause in KL flats. A full chemical wash recovers 90%+ of design airflow within 90 minutes.
Bad smell from aircond
Mould inside the blower wheel and drain. Chemical wash with anti-bacterial treatment removes the source; not a cologne-spray fix.
High electricity bill
Dirty coil makes the compressor run longer. Routine chemical wash typically recovers 15-25% of inverter efficiency for KL households.
