Why choose us?
Since 1988, our family business has been keeping Singapore buildings and homes comfortable. We believe air conditioning is about more than cool air — it’s about clean air, peace of mind, and honest service you can rely on for years to come.
A Family Business Since 1988
Sin Lee Aircon has always been a family business, built on trust and integrity. For more than 30 years, our promise has remained simple: no upselling, no unnecessary work — just honest solutions that add real value. We care for your space the way we care for our own.
End-to-End Expertise
From consultation through installation and maintenance, we provide complete, end-to-end service. Over the years, we’ve taken on many challenging projects — and built the know-how to get every detail right.
Certified, Skilled Professionals
Our team is professionally trained, BCA-registered, and BizSafe Level 3 certified. We’re also listed on the BCA register for trained installers for structural supports of aircon units — a mark of the safety and compliance we bring to every job.
Raising the Standard
Aircon servicing should mean more than cool air. We go further — delivering clean air, lasting comfort, and systems built to perform. And while we hold ourselves to higher benchmarks, our services remain honest, reliable, and fairly priced.

Melvin, Telok Kurau
We engaged Sin Lee Aircond to install airconditioners for 2 of our restaurants. Their service is professional - from planning/advisory, drawing, team meetings and corresponding w QPs, to ground work execution (workers were meticulous in installation).
Worth mentioning is their good after sales service as well! Highly recommend restaurateurs to engage their service.
