Serving Singapore Homes Since 2005

Our Story

Mr Chong founded Coolbest Aircon in 2005 in a Jurong West flat, with one tool kit and a clear rule — quote fairly, do the work right, stand behind it. That first customer became the second, the second became a block-full, and eighteen years later we're one of the most-reviewed aircon teams in Singapore's West Region.

Today, we operate from our HQ at Block 540 #03-1108 Jurong West Avenue 1, dispatching technicians daily across Jurong West, Jurong East, Clementi, Bukit Batok, Choa Chu Kang, Bukit Panjang, Bukit Timah, and the rest of the island. Same-day response in the West, next-day across the board.

What Makes Us Different

Aircon servicing has no shortage of operators — what makes the job work is transparency. We publish our per-unit prices upfront (S$50 for one, S$55 for two, scaling predictably). If diagnosis uncovers something more, we quote it before touching anything. You'll never get a surprise invoice from us.

Every job is covered by a 90-day workmanship warranty. If what we fixed recurs within 90 days, we come back and fix it at no charge. The warranty covers the work we performed — we don't slip in fine print that narrows it to nothing.

Our Team

Every technician on the Coolbest team is trained directly by Mr Chong and brand-certified on the major manufacturers — Daikin, Mitsubishi Electric, Mitsubishi Heavy Industries, Toshiba, LG, Panasonic, Midea, Sharp, and York. That matters because when your Daikin unit flashes E7 or your Mitsubishi shows P8, we know the fault tree by memory rather than guessing.
