From a single-split replacement to a four-fan-coil multi-split for a 5-room HDB BTO, Coolbest handles the full installation: load sizing, brand recommendation, BCA-compliant external brackets, copper trunking, condensate routing, vacuum and pressure test, and first-run verification.
What goes into a proper aircon installation
A bad aircon install causes problems for years. A vacuum step skipped today shows up as a failed compressor in three years. A copper joint flared incorrectly leaks refrigerant slowly until the system gives up.
A proper installation has six non-negotiable steps:
- Load sizing — matching BTU to room size and direction of sun
- BCA-compliant bracket mounting — external brackets that meet Singapore building rules
- Copper trunking — concealed where possible, protected against UV
- Condensate routing — sloped 1° downward to a drain or condensate pump
- Vacuum + pressure test — pulling moisture out before refrigerant is charged
- First-run verification — measuring supply temperature with a probe
We don’t skip any of these. The vacuum step alone takes 30+ minutes per system; some “budget” installers skip it to fit more jobs in a day.
HDB-specific considerations
For HDB installations, the external bracket needs to comply with BCA Singapore guidelines. The bracket size, the wall anchors, and the corrosion treatment matter — Singapore’s coastal humidity will eat a non-galvanised bracket in 2–3 years.
We also handle the town council notification on your behalf. The notification is straightforward but easy to forget; without it, the installation can be challenged later by the town council.
Brand recommendations for Singapore homes
For most Singapore HDB and condo bedrooms, our shortlist is:
- Daikin iSmile — quietest at low fan speed, great for bedrooms
- Mitsubishi Starmex — best long-term reliability for the price
- Panasonic X-Deluxe — strongest dehumidification (good for west-facing rooms)
- Toshiba Hi-Wall — best value entry point
- LG DualCool — newest inverter tech, fast cooling
We carry no brand quotas. The recommendation depends on your room, your usage hours, and your warranty preference.

In The Field
What Singapore Homeowners Say
Real reviews from Jurong West, Clementi, Bukit Batok, and beyond.
"Needed a multi-split installed for a new BTO handover. Team handled the HDB approvals and brackets, vacuumed the pipes properly, and tidied up. Fair price, zero drama."
"Replaced four old fan coils with new Mitsubishi Starmex over two days. Clean job, copper trunking is invisible, and the cold air is night and day better."
