15 Best Aircon Companies in Central Singapore
This is our aircon ranking narrowed down to companies with a registered address in Central Singapore. Handy if you want a firm that's nearby for repeat servicing.
The scoring is the same as our island-wide guide: BCA ME01 grade, years since incorporation, other BCA workheads held and how complete the public record is.
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 15 firms and all of them are shown. Google reviews are shown as not checked until we've checked them for every firm here. Full method

Before you hire
Ask about servicing contracts if you've got several units, they're usually cheaper per visit. And ask what happens if a unit needs a gas top-up, some firms include it and some don't.
Questions people ask
Will they come to my area?
Most aircon firms work island-wide. We grouped these by registered address only.
How often should I service my aircon?
It depends on how much you use it. Ask the contractor what they'd recommend for your usage, and get it written into any contract.
