Who We Are
About Supply Cool
28 years of trusted aircon and electrical service across Singapore.
In Business Since 1996
Supply Cool Air Condition & Electrical Engineering was founded in 1996 with one goal: to provide Singapore homeowners and businesses with honest, reliable aircon and electrical service — at a fair price.
Over the past 28 years, we've completed thousands of jobs across the island — from simple aircon servicing in HDB flats to full multi-split system installations in landed homes and commercial offices. Our team has grown, but the approach hasn't changed: turn up on time, do the job right, and don't overcharge.
We're a small, professional team — not a franchise. When you call us, you speak to someone who knows the work firsthand. We'll tell you honestly if a unit is worth repairing or if a replacement makes more sense. We won't recommend work that isn't needed.
Our technicians are fully trained and licensed for all electrical works, and experienced with all major aircon brands including Daikin, Mitsubishi, Panasonic, LG, Samsung, and more. We carry common spare parts to minimise return visits.

Customer Reviews
100+ five-star reviews from verified customers across Singapore
"Called them on a Saturday afternoon when my aircon stopped working completely. Technician arrived within 2 hours, diagnosed a faulty PCB, and had it fixed the same evening. Reasonable price and no hard-selling. Will definitely call again."
"Got three wall units installed in my new flat. Clean workmanship, no mess left behind. They also checked my electrical points at no extra charge. Very professional — would recommend to anyone in the area."
"Very professional team. They did a chemical wash on two units that hadn't been serviced in years — both are running like new. Honest pricing, arrived on time, and answered all my questions patiently."
"My aircon was leaking water badly on a weekday morning. Called them and they arrived within a few hours. Fixed the blockage and checked the whole unit. Fair pricing, very professional. Highly recommend."
"Used them for a full 4-unit aircon installation in my new condo. Neat trunking, punctual, and they left the place clean. Also did my kitchen tap and two ceiling lights on the same visit. One-stop shop!"
"Honest and efficient. They told me upfront that my compressor could still be repaired rather than pushing me to replace the whole unit. Saved me a lot of money. That kind of honesty is rare."
"Third time using Supply Cool and they never disappoint. Regular servicing keeps my aircon running well all year. Reliable, affordable, and always on time."
"Called about a flickering light that kept tripping my circuit breaker. They diagnosed a faulty fitting within 10 minutes and replaced it on the spot. Quick, clear, and no overcharging."
"Gas top-up done professionally. They tested the unit before and after, showed me the pressure readings, and explained what they were doing throughout. Transparent and trustworthy."
