In Singapore your aircon runs most days of the year, so who services it matters more than in most places. Plenty of aircon outfits are small, so for this guide we only looked at companies holding BCA's air-conditioning, refrigeration and ventilation workhead, ME01.

They're ranked on ME01 grade, years since incorporation, how many other BCA workheads they hold and how much of their record we could check. The top of the list leans towards larger engineering firms. If you only need a home unit serviced, scroll down a bit too, smaller firms can be quicker to book.

How this list was ranked

Each firm gets 0 to 5 points on four things, multiplied by a weight: BCA ME01 (Air-Conditioning, Refrigeration & Ventilation) grade ×4, years since incorporation ×2, other BCA workheads ×2, and how complete its public record is ×1. The total is scaled to 10. We checked 61 firms and show the top 20. Google reviews are shown as not checked until we've checked them for every firm here. Full method

Before you hire

Ask what a general service actually includes, it varies alot between companies. Ask whether chemical cleaning or overhaul is quoted separately and what parts are covered under warranty. For new installs, get the brand, model and piping length on the quotation.

Questions people ask

What is BCA ME01?

The workhead for air-conditioning, refrigeration and ventilation works. Grades run from L1 to L6.

Why use ME01 as the entry rule?

It shows the company is registered with BCA as an aircon contractor. It doesn't tell you on its own how good the servicing is, which is why we're adding reviews once they're checked for every firm.
