"Mr. Heng's team came within 2 hours and did a thorough chemical wash on all 3 of my units. The free gas top-up saved me at least RM150 compared to other companies. My rooms are freezing cold again!"

"I was worried about hidden charges after a bad experience with another company. PJ Kool quoted RM160 on WhatsApp and that's exactly what I paid. No surprises. The technician was experienced and professional."

"Our restaurant in Damansara Uptown uses them for monthly maintenance. They always work around our business hours and our airconds have been running perfectly since we started the contract."

"My aircond was leaking water for weeks. The technician diagnosed the blocked drainage in 10 minutes and fixed it on the spot. RM50 diagnostic fee was waived since I proceeded with the repair. Very fair."

Common Questions

Aircond Service FAQ!

Is the gas top-up really free with chemical wash?
Yes, every chemical wash booking includes a FREE gas top-up of up to 10kg of refrigerant gas (R22, R32, or R410A). Most competitors charge RM50-RM150 separately for this service. We include it because proper gas levels are essential for your aircond to cool effectively after a deep clean.
Will you send a trainee to my home?
Never. We have a strict no-trainees policy. Every job is handled by senior technicians with 10-20+ years of hands-on experience. Mr. Heng (founder), Ahmad, and Raju are our core team — all seasoned professionals who have serviced thousands of units.
What is the difference between standard cleaning and chemical wash?
Standard cleaning (RM85) covers filter washing, cover cleaning, and blower wipedown — it's a surface-level maintenance clean. A chemical wash (from RM160) involves full dismantling of the indoor unit, deep alkaline chemical cleaning of the evaporator coil and blower, drainage flush, and includes a FREE gas top-up. Chemical wash is recommended every 6-12 months for optimal performance.
Do I have to pay the RM50 diagnostic fee even if I proceed with repair?
No — the RM50 diagnostic fee is waived if you proceed with the recommended repair. The fee only applies if you choose not to go ahead with the repair after our technician has diagnosed the problem.
Which areas do you cover?
We cover the entire Petaling District including Petaling Jaya, SS2, Damansara Jaya, Damansara Utama, Kota Damansara, Bandar Utama, Taman SEA, Section 14, Section 17, Subang Jaya, Kelana Jaya, and Puchong. No extra transport charges for these areas.
What warranty do you provide?
Every chemical wash and repair comes with a 30-day workmanship warranty and a 1-month warranty on gas leaks. If your aircond has any issues related to our work within the warranty period, we'll come back and fix it at no additional cost.
