Common Aircon Problems
Aircon Issues We Fix Every Day Across Singapore
Six problems account for 90% of service calls in Singapore. We see them every single day — and we know exactly how to fix each one.
01
Not Cooling Properly
Warm air, weak airflow, rooms taking hours to reach temperature
02
Water Leaking From Unit
Drips onto the floor, stains the wall, or pools in the service balcony
03
Musty or Foul Smell
Mould and biofilm in the coil — a chemical wash fixes this fast
04
Blinking Error Lights
Error code flashes, unit won't start, or trips the circuit breaker
05
Skyrocketing Power Bills
Your unit is clogged and cycling — losing efficiency every month

Aircon Chemical Wash & Overhaul

Reviews
What Singapore Homeowners Say
4.8 average across 200+ Google reviews. Real feedback from Jurong, Bishan, Boon Lay and beyond.
"Called Coolbest on Saturday morning because our bedroom AC was leaking onto the floor. Uncle came within three hours, found the drainage was clogged, cleaned it out and explained exactly what had happened. Paid S$70, no upsell. Will definitely book again."
Rachel T.
Jurong West
"Got all three units chemical washed before moving out of our condo in Bishan. They brought the Certificate of Service and our landlord released the full deposit without any fuss. Photos before and after made the difference."
Marcus L.
Bishan
"Installed a new Mitsubishi Starmex system for our HDB in Boon Lay. Mr Chong himself came to do the site survey, sized it right, and the team installed in one day. No leaks, no noise, running perfect six months in."
Farah A.
Boon Lay
"Our retail shop in Clementi needed a quarterly maintenance contract after the old contractor kept missing visits. Coolbest locked in dates, sends a service log every time, and charged a third less than we were paying. Stable and boring — exactly what I wanted."
Benjamin K.
Clementi
"Aircon was blinking funny and blowing warm air. They diagnosed a failed capacitor, replaced it on the spot and charged S$110 total. Honest price, no mystery 'diagnostic fee' tacked on. I've already recommended them to two neighbours."
Priya S.
Choa Chu Kang
"The team was punctual, wore shoe covers, brought their own drop cloth for the floor, and even deodorized the units before leaving. Genuinely clean work. Paid S$100 for five units — hard to beat."

FAQ
Questions Singapore Homeowners Ask Us
If your question is not here, WhatsApp us — we answer within the hour during business hours.
How much does aircon servicing cost in Singapore?
General aircon servicing at Coolbest starts at S$50 for 1 unit and scales to S$115 for 6 units — a flat per-unit rate with no hidden charges. Chemical wash runs S$90–S$180 per unit depending on the system type. You get a written quote before any paid work begins.
How quickly can you come for an urgent aircon repair?
Same-day callout is available between 9am and 6pm for customers in Singapore's West Region (Jurong, Boon Lay, Clementi, Choa Chu Kang, Bukit Batok). Central Region bookings usually go out the next working day. WhatsApp +65 9182 5233 and you'll get a confirmed slot within the hour.
Do you offer a warranty on aircon servicing and repairs?
Every service and repair at Coolbest is covered by a 90-day workmanship warranty. If the same fault returns within 90 days of our visit, we come back and fix it at no charge. The warranty is written on your invoice — no small print, no exclusions for 'normal wear'.
Which aircon brands can you service and repair?
Our technicians are trained across every major brand sold in Singapore: Daikin (including VRV and Inverter Smile), Mitsubishi Electric (Starmex and Mr. Slim), Panasonic (Econavi), Toshiba, LG and Hitachi. We carry common replacement parts — PCBs, capacitors, fan motors — for each brand so most repairs finish in one visit.
Do you service aircons in Bishan, Marine Parade and Central Singapore?
Yes — we cover the whole island. Our base in Jurong West means same-day response across the West Region, while Central areas like Bishan, Toa Payoh, Queenstown and Marine Parade are typically next-day. Travel is included in the per-unit price; no island-wide surcharge.
What's the difference between a chemical wash and a chemical overhaul?
A chemical wash dismantles the indoor fan coil and soaks it in alkaline solution — the right fix for mould, smell and weak airflow. A chemical overhaul goes further: we also remove the outdoor condenser, clean the compressor and reassemble with new insulation. Overhaul is usually recommended every 3–5 years for units older than 7 years.
