Common Aircond Problems in Kuala Lumpur
If any of these match your situation, our senior technicians can diagnose and fix it — often on your first visit.
AC runs but the room stays warm
Your unit runs for hours but never really cools the room. This is usually low refrigerant gas or a coil blocked with dust and bacteria — both fixed with a chemical wash.
Water dripping from the indoor unit
Water staining your wall or dripping onto furniture. A blocked drainage pipe is the most common cause — a straightforward fix when handled by an experienced technician.
Musty or foul smell on startup
A stale or musty odour every time the AC turns on means mold and bacteria have built up inside the unit. A chemical wash removes 99.9% of bacteria and eliminates the smell.
Electricity bill keeps climbing
A dirty or gas-depleted unit works much harder to reach your set temperature, pushing your TNB bill higher. Regular servicing keeps it running at peak efficiency.
Worried about getting a trainee
A previous company sent an inexperienced apprentice who caused more damage. We have a strict no-trainee policy — every job is handled by a senior technician with 10-20+ years of experience.
Our Fix
Senior technicians. Transparent pricing. 30-day warranty.
We've solved all five of these problems for 10,000+ customers across Kuala Lumpur and Klang Valley since 2003.

What Our Customers Say
Trusted by 10,000+ Customers

“Booked a chemical wash and Ahmad came on time, explained everything he was doing. My aircond is ice-cold again — like new. Will definitely rebook for my bedroom unit.”
“Been using PJ Kool for 3 years now. They're the only service that includes free gas top-up. Saved me hundreds compared to my old contractor.”
“Our restaurant in Damansara Uptown uses PJ Kool for monthly maintenance. Units stay clean, no more customer complaints about the smell. Professional and reliable team.”
“I called on a Saturday because my AC was leaking badly. Mr. Heng came the same day and fixed the drainage blockage. Honest pricing, no hard sell on unnecessary repairs.”
“What I appreciate most is they only send experienced technicians. Had a bad experience before with another company sending a trainee who caused more damage. PJ Kool is different.”
“Called for a diagnostic on my office ceiling cassette unit. Turned out it just needed a chemical wash, not a compressor replacement as another company quoted. Saved RM 2,000+.”

Aircond chemical wash in Kuala Lumpur starts from RM 160 per wall-mounted unit, inclusive of free gas top-up (up to 10 kg) and a 30-day workmanship warranty. Our pricing is the same across all coverage areas — no distance surcharges for KL customers.
Our office is in Fraser Business Park, Kuala Lumpur (55200). While our name references PJ because that's our largest customer base, we're actually a KL-headquartered company. Our technicians serve both KL and the wider Klang Valley daily.
Our chemical wash includes full indoor unit dismantling, chemical cleaning of evaporator coils, blower fan cleaning, drainage flushing, reassembly, and a FREE gas top-up (up to 10 kg of R22, R32, or R410A refrigerant). We also test the unit's cooling performance before leaving.
Standard cleaning covers filter washing, cover wiping, and basic blower cleaning without dismantling the unit. Chemical wash involves fully dismantling the indoor unit, deep-cleaning the evaporator coils with specialised chemicals, flushing the drainage system, and includes a free gas top-up. Chemical wash is recommended for units that haven't been serviced in 6+ months or are blowing warm air.
In Malaysia's tropical climate, we recommend standard cleaning every 3-4 months and a chemical wash every 6-12 months for residential units. Commercial units — especially in F&B outlets — should be chemically washed every 3-6 months due to higher usage and grease exposure.
