Air handling units, chilled water systems, ducting for a whole office floor. Commercial air-conditioning and mechanical ventilation (ACMV) is a different scale from home aircon, and the contractor needs to be cleared for it.

This guide only includes firms holding BCA's ME01 workhead at grade L3 or above. They're ranked on that grade, years since incorporation, other BCA workheads and how complete their 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 29 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 for similar projects in the same building type, a clinic has different ventilation needs from an office. Ask who does the maintenance after handover and on what terms. And get the system design checked by your M&E consultant if you have one.

Questions people ask

Why the L3 cut-off?

Commercial ACMV contracts are usually larger, and higher ME01 grades mean BCA has cleared a firm for bigger work.

Can these firms service home units?

Some do. For a flat, our main aircon guide is a better place to start.
