Selling your HVAC business? Contracts are the whole game.
Air conditioning and refrigeration businesses span the widest multiple range in the trades — because the gap between install shops and contracted mechanical services is that large.
Australian air conditioning and refrigeration businesses typically sell for 2.5 to 4.0 times normalised EBITDA — the widest and highest trade band — because the category spans everything from residential split-system installers to contracted commercial mechanical services. Programmed maintenance on commercial plant is the most prized revenue in the entire trades sector, and businesses built on it can clear 5 times.
To 5.5× at the premium end: programmed maintenance contracts, commercial mechanical services, refrigerant handling depth beyond the owner.
Indicative market observation, not a valuation of your business. Where your business sits in — or beyond — the band is exactly what a valuation establishes.
What buyers pay a premium for
- ·Programmed preventative maintenance contracts on commercial plant — the gold standard of trades revenue
- ·Refrigeration books serving supermarkets, food service and cold chain, where downtime is intolerable and relationships sticky
- ·Refrigerant handling licences spread across technicians rather than concentrated in the owner
- ·Mechanical services capability (design, install, maintain) that positions the business up the value chain from box swaps
- ·Escalation clauses and multi-year terms in the contract base
What quietly kills HVAC deals
Residential install dependence is the main one: split-system volume is seasonal, marketing-driven and margin-thin, and buyers price it like retail rather than services. Warranty tails on installed plant scare buyers when service records are thin. And as everywhere in the trades, the licence stack — refrigerant handling, electrical work, plumbing interconnects — must survive the owner leaving, or the deal restructures around them staying.
Who is buying HVAC businesses
This is the segment where consolidation is most advanced globally, and Australian buyers know it: facility-services groups, mechanical services companies filling geographic gaps, and PE-backed trades platforms for whom HVAC is usually the anchor trade because of its contract density. Strategic buyers will pay for a contract book they can service with existing overheads, which is why contract-heavy targets attract competing interest that install shops never see.
When to start
Contract books take years to build, which is exactly why they are worth so much. If your revenue is install-weighted, every maintenance agreement you attach to the install base between now and sale converts one-off history into saleable future. Start that conversion, and the licence succession, two to three years out — and get the baseline valued now so the progress is measurable.
Common questions.
Why do HVAC businesses sell for more than plumbing or electrical?+
Contract density. Commercial plant legally and practically requires programmed maintenance, so the industry structurally generates recurring revenue in a way reactive trades do not. Buyers pay for predictability, and HVAC has the most of it.
My business is mostly residential installs. What is realistic?+
The bottom of the band, priced on demonstrated earnings rather than potential — unless you have started attaching service plans to the install base, in which case the trajectory itself becomes part of the story. An honest valuation will show you what the mix shift is worth before you sell versus after.
Does cold-chain refrigeration attract different buyers?+
Yes — food-retail and logistics-adjacent buyers who care about response-time coverage and technician depth more than headline margin. Refrigeration books are often more valuable than their EBITDA suggests because of who needs them.
