Aircond Problems PJ Homeowners Face Every Day
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 down. 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 technician sent an inexperienced apprentice who caused more damage or failed to fix the problem. 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 PJ and KL since 2003.

What Our Customers Say

FAQ
Common Questions About Aircond Servicing in PJ
Quick answers to the questions we hear most from homeowners and businesses in Petaling Jaya and Klang Valley.
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.
Never. PJ Kool Aircond Service has a strict policy against sending trainees. Every job is handled by our senior technicians with 10-20+ years of experience. This is one of our core differentiators — you will never have an inexperienced person working on your aircond.
Yes. Every chemical wash and repair booking includes a FREE gas top-up of up to 10 kg (R22, R32, or R410A). Most competitors charge RM 80-150 separately for this. We include it because topping up gas after a chemical wash ensures optimal cooling performance.
