4.8 out of 5 based on 200+ reviews from HDB, condo, and landed homeowners
"Just collected our keys at Yishun Beacon and needed aircon installed for all 3 bedrooms. Coolbest handled the whole System 3 setup in a day — piping, trunking, electrical, everything. BCA compliant and neat work. Very impressed."
Rachel T.
"Our aircon in Chong Pang was leaking badly and smelling musty. The Coolbest technician came same day, did a chemical overhaul, and the unit runs like new. No more mould smell. Fair price too."
Kelvin N.
"Been using Coolbest for quarterly servicing of our 4-room HDB near Northpoint City. Always punctual, always transparent pricing. The technician even pointed out our drainage was getting slow and flushed it before it became a leak."
Priya M.
"Managing a small office near Yishun Industrial Park A. Coolbest maintains our ceiling cassette units on a regular contract. Reliable, responsive on WhatsApp, and they always show up on time. Highly recommend for commercial maintenance."
Daniel C.
"My aircon was blowing warm air after months of running non-stop in this Yishun heat. Technician found the gas was low, did a top-up and a chemical wash. Room is freezing cold again. Honest guy — could have charged me for more but didn't."

FREQUENTLY ASKED QUESTIONS
How much does aircon servicing cost in Yishun?
General aircon servicing in Yishun starts from S$50 for 1 unit, S$55 for 2 units, S$70 for 3 units, S$85 for 4 units, S$100 for 5 units, and S$115 for 6 units. This includes fan coil cleaning, filter washing, and drainage flushing. All prices are upfront with no hidden charges — same rates whether you live in Yishun Central, Chong Pang, or Nee Soon.
How often should Yishun residents get an aircon chemical wash?
Given Yishun's high humidity and proximity to ongoing construction projects like the North-South Corridor, we recommend a chemical wash every 4 to 6 months. The extra dust and moisture in the North Region accelerates mould and grime buildup in your coils and drainage. Homes near Yishun Avenue 2 or the NSC works may benefit from more frequent servicing.
Do you install aircon systems for new BTO flats in Yishun?
Yes, we handle BCA-certified aircon installations for all Yishun BTOs including Yishun Beacon, Chencharu Grove, and Yishun Glade. We manage everything — piping, trunking, electrical wiring, HDB permit applications, and the post-installation SP Services Form CS/5H. All installations comply with HDB's 110kg weight limit per wall panel and the 20-amp DP isolator requirement.
Can I get same-day aircon service in Yishun?
Yes, we offer same-day service across Yishun and the North Region 7 days a week. Our technicians access Yishun quickly via the SLE and TPE expressways. Whether you are near Northpoint City, Khatib MRT, or the HDB blocks along Yishun Ring Road, we can usually arrange a same-day appointment.
Why does my aircon in Yishun smell mouldy even after servicing?
Yishun's tropical humidity (often above 80%) creates ideal conditions for mould to grow deep inside your aircon's blower fan and evaporator coils. A standard servicing only cleans the surface. If the musty smell persists, you likely need a chemical wash (from S$80) or a full chemical overhaul (from S$120) that soaks and cleans every internal component. We also apply anti-bacterial treatment to slow regrowth.
What warranty do you offer on aircon services in Yishun?
All our services come with a 90-day workmanship warranty. If the same issue returns within 90 days, we come back and fix it at no additional cost. This covers general servicing, chemical wash, chemical overhaul, gas top-up, and repair work for all customers across Yishun and the North Region.
