Installation Done Right Means Installation Done Once

A typical HDB or condo aircon is meant to last 10–12 years. The install quality in the first day decides most of that lifespan — BTU sizing, piping route, insulation, vacuum depth, mounting angle. Rush any of those and you’ll be paying for premature compressor failure or leaking copper within 3 years.

We’ve been installing in Singapore since 2005. Every system we fit is sized, routed, insulated and commissioned to a checklist — then pressure-tested before we hand you the remote.

Systems We Install

  • Window-type units — older HDB flats, simple retrofits
  • Split-type systems (1:1) — one indoor unit paired to one outdoor condenser, most common bedroom install
  • Multi-split systems (1:2 through 1:5) — one outdoor condenser running multiple indoor units, standard for new condo and landed homes
  • Cassette and ceiling-mount — commercial and some larger landed properties
  • VRV / VRF commercial systems — quoted on-site survey

Brand Coverage

We install every major brand sold in Singapore and stock common parts for each:

  • Daikin — Inverter Smile, Perfera, and VRV commercial
  • Mitsubishi Electric — Starmex and Mr. Slim
  • Panasonic Econavi — X, XE, AeroSmart
  • Toshiba — Daiseikai inverter series
  • LG — Dual Inverter
  • Hitachi — Shirokuma RAS series

If you haven’t decided on a brand yet, we’ll give you a no-pressure comparison during the site survey — based on room size, existing wiring, NEA energy rating, and your budget.

What Our Installation Covers

Pre-install (on-site survey):

  • BTU sizing for each room (under-sized = poor cooling, over-sized = short-cycling and higher bills)
  • Route check for HDB-compliant trunking
  • Outdoor unit placement check (ventilation, noise, access for future servicing)
  • Electrical load check (some older HDB panels need an upgrade for multi-split systems)

Install day:

  • Copper piping cut, flared and bent to the exact route
  • Tropical-grade insulation wrapped around every metre of pipe (no budget insulation that sweats in humidity)
  • Trunking fitted to HDB guidelines — colour-matched to your wall where possible
  • Indoor unit mounted, spirit-level checked (drainage won’t flow if the mount is off-angle)
  • Outdoor unit secured on anti-vibration mounts

Commissioning:

  • Full vacuum pump down to manufacturer spec (typically 500 microns or lower)
  • Nitrogen pressure leak test (30-minute hold at operating pressure)
  • Refrigerant charged to exact spec for the pipe run length
  • 60-minute run test with cold-discharge temperature measurement
  • Remote programmed, owner’s manual walked through with you

Pricing (Labour — Unit Cost Separate)

  • Single split system (1:1): S$300–450 labour
  • Multi-split (1:2 or 1:3): S$600–900 labour
  • Multi-split (1:4 or 1:5): S$900–1,400 labour
  • Cassette / ceiling-mount: from S$1,200
  • Add-on: old unit removal and HDB-compliant disposal — S$60/unit

All labour is covered by our 90-day workmanship warranty. The unit itself carries the manufacturer’s warranty (typically 5 years on the compressor, 1 year on the parts).

HDB Compliance — Why It Matters

HDB has strict guidelines on trunking colour, external bracket placement, and drainage discharge points. An install that ignores these can result in a fine, a forced re-route at your expense, or issues at resale. We install to HDB spec by default — it’s the only way we know how.

"Called Coolbest on Saturday morning because our bedroom AC was leaking onto the floor. Uncle came within three hours, found the drainage was clogged, cleaned it out and explained exactly what had happened. Paid S$70, no upsell. Will definitely book again."

"Got all three units chemical washed before moving out of our condo in Bishan. They brought the Certificate of Service and our landlord released the full deposit without any fuss. Photos before and after made the difference."

"Installed a new Mitsubishi Starmex system for our HDB in Boon Lay. Mr Chong himself came to do the site survey, sized it right, and the team installed in one day. No leaks, no noise, running perfect six months in."

FAQ

Installation — FAQs

If your question is not here, WhatsApp us — we answer within the hour during business hours.

Which aircon brands can you service and repair?
Our technicians are trained across every major brand sold in Singapore: Daikin (including VRV and Inverter Smile), Mitsubishi Electric (Starmex and Mr. Slim), Panasonic (Econavi), Toshiba, LG and Hitachi. We carry common replacement parts — PCBs, capacitors, fan motors — for each brand so most repairs finish in one visit.
How often should I service my aircon in Singapore?
Quarterly (every 3 months) for HDB flats and condos under normal use. Monthly for households with pets, allergies or heavy 24/7 running. Commercial spaces should service monthly to quarterly depending on foot traffic. Singapore's humidity grows mould faster than most climates — quarterly is the bare minimum.
Do you provide a Certificate of Service for end-of-tenancy handover?
Yes. Our end-of-tenancy package includes a signed Certificate of Service, before/after photos, and an invoice in the format most Singapore landlords accept. Book us 3–5 days before your handover date so there's buffer if anything needs a follow-up wash.
How can I pay for aircon servicing?
We accept PayNow, bank transfer, cash and major credit cards (Visa, Mastercard, AMEX). Payment is due on completion of the job — no deposit required for routine servicing. Commercial contracts are invoiced monthly or quarterly.
