KEEPING YISHUN COOL SINCE 2005
From a one-man operation to one of Singapore's most trusted aircon servicing teams — now proudly serving Yishun and the entire North Region with honest work at fair prices.
MR CHONG — 18+ YEARS OF HONEST AIRCON SERVICE
Mr Chong founded Coolbest Aircon in 2005 with a simple belief: aircon servicing in Singapore shouldn't come with hidden fees and unclear pricing. After years of working in the HVAC industry and seeing homeowners get overcharged for basic services, he decided to do things differently.
Over the years, Coolbest Aircon has built a strong presence in the North Region. Our technicians regularly serve Yishun residents — from the established HDB blocks around Chong Pang and Nee Soon to the newer BTO estates like Yishun Beacon and Chencharu Grove. We understand the unique needs of this area: the high humidity that accelerates mould growth, the dust from ongoing North-South Corridor construction, and the growing demand from young families moving into new flats.
Today, Coolbest Aircon has grown into a trusted name across Singapore, servicing over 10,000 units and maintaining a 4.8-star Google rating. But the core values remain the same: transparent pricing, reliable workmanship, and treating every customer's home with respect.
OUR CORE VALUES
These aren't just words on a wall — they guide every job we do, every quote we give, and every technician we train.
TRANSPARENT PRICING
We quote upfront based on number of units. No hidden charges, no surprise fees after the job is done.
QUALITY WORKMANSHIP
Every service backed by our 90-day warranty. If the same problem returns, we fix it free of charge.
PUNCTUAL & RELIABLE
We show up on time, every time. Same-day service available 7 days a week across Yishun and the North Region.
CUSTOMER FIRST
We treat every home with respect — shoe covers, clean-up after service, and honest advice on what you actually need.
SERVING YISHUN & THE NORTH REGION
Our technicians cover all of Yishun and the surrounding North Region daily — from Yishun Central and Northpoint City to Sembawang, Khatib, Springleaf, and Woodlands. With easy access via the SLE and TPE expressways, we reach Yishun residents quickly for same-day service.
We stock genuine spare parts for all major brands — Daikin, Mitsubishi, Toshiba, LG, Panasonic, Midea, and more — so most repairs can be completed on the first visit without waiting for parts to arrive.
