Fix warranty, in writing

“Aircon died Saturday night, kids couldn't sleep. WhatsApp'd CoolFast at 9pm, technician at the door by 10:20pm. Fixed a blocked drain line in 40 minutes for $120 flat. No weekend surcharge hidden in the quote.”

Priya S.
HDB Serangoon, 4-room

“Three companies quoted me $400 for a gas top-up and servicing. CoolFast found the leak first, sealed it, then topped up. Total $220 and they wrote the 14-day leak guarantee on the receipt.”

Marcus T.
Condo, Tiong Bahru

“My bedroom unit was cycling on and off every 5 minutes. The technician explained it was a faulty thermistor — $38 part — and swapped it in 20 minutes. I got a WhatsApp with the fault code and the old part before he left.”

About CoolFast

One Singapore-licensed team, eight technicians, no subcontracting.

We started CoolFast in 2019 after getting tired of same-day calls that turned into three-day waits. We are BCA licensed (L006-2019), BizSafe 3 certified, and carry $1M public liability insurance. Every technician on a CoolFast van is an employee — we do not subcontract. Based in Ubi, serving all of Singapore.

What Singapore aircon owners usually ask

Is 90 minutes realistic in Singapore traffic? +

96% of last quarter's same-day jobs arrived within 90 minutes of confirmation. If we miss that window, the $120 call-out fee is waived.

Are you licensed and insured? +

Yes — BCA licensed (L006-2019), BizSafe 3 certified, and $1M public liability insured. We show the paperwork on every first visit.

Do you work after-hours and weekends? +

Same-day covers 8am–10pm, 7 days a week including weekends. After-hours (10pm–8am) and public-holiday call-outs add a flat $40.

What if you can't fix it on the spot? +

The $120 diagnostic is flat. If a specialty part is needed we order it and hold the diagnostic fee — the return visit has no additional call-out charge.

Do you handle all aircon brands? +

Yes — Daikin, Mitsubishi, Panasonic, LG, York, Midea, and others. We don't upsell a brand swap unless the unit is over 12 years old.

Do you service HDB, condo and landed? +

All three, anywhere in Singapore. Some condos require a building pass — add 20 minutes if you don't have one cleared.

Technician at your door in 90 minutes — or the call-out fee is waived.

$120 flat. No hidden fees. 30-day fix warranty on every job.
