Selling an HVAC business
HVAC companies are valued on the durability of the service base, not on last summer's replacement revenue. Buyers look hardest at maintenance agreement count and renewal behavior, the mix between service and installation, technician retention, and whether the owner still runs sales, dispatch and pricing personally.
Written and reviewed by Antoine Campbell. Last reviewed .
What drives value in HVAC
A maintenance base is the closest thing to recurring revenue in the trades. It also feeds the replacement pipeline, because the technician in the basement in January is the one who sells the new system in April.
- Maintenance agreements: how many, at what price, and what percentage renew
- Service and repair revenue as a share of total, versus new installation
- Gross margin by job type, and whether pricing is disciplined or negotiated per call
- Technician count, tenure, licensing, and whether apprentices are being developed
- Commercial contract work versus residential one-off calls
Cash conversion and seasonality
Residential work usually collects at completion; commercial and new construction can stretch out and may involve retainage. Both matter because HVAC has a pronounced seasonal shape: shoulder months consume the cash the peak months produced.
A buyer will look at the low month, not the average month, when sizing working capital. Show a full twelve months, not a trailing summer.
Owner dependence in this trade
License holding is the one that stops transactions. Requirements vary by state and locality; verify with your state licensing board whether the qualifying individual can be replaced and what that process takes.
- The owner personally quoting replacements and setting prices
- Dispatch decisions and technician scheduling running through the owner
- Key commercial accounts held on a personal relationship
- The owner holding the master license the company operates under
Diligence items specific to HVAC
- Maintenance agreement list with start dates, pricing and renewal history
- Warranty and callback log, including labor warranty exposure
- Refrigerant handling and EPA Section 608 technician certifications
- Fleet list with mileage and condition
- Distributor rebate and co-op arrangements, and whether they transfer
- Workers compensation experience modifier and claims history
Transition
Technicians decide whether an HVAC acquisition works. Their pay structure, take-home consistency and who they report to matter more to them than who owns the company. Retention planning starts before closing, not after.
What Maurant needs to evaluate this
- Three years of tax returns and year-to-date financials
- Revenue split: maintenance, service, replacement, new construction, commercial
- Maintenance agreement schedule
- Technician roster with tenure and licensing
- Fleet and equipment list
- Whether the operating property is owned or leased
When Maurant is not the right buyer
- New-construction-only shops with no service base
- Companies where the owner personally holds the only qualifying license and no path exists to replace it
- Operations with unresolved warranty or callback liability
Questions owners ask
- Does my maintenance base really matter that much?
- Yes. It is the most transferable part of an HVAC company and it drives the replacement pipeline.
- Do you buy the building too?
- Where the shop and yard are owned, usually yes, financed on a separate leg that closes at the same time.
- What happens to my technicians?
- They are the reason for the acquisition. Retention terms can be written into the agreement.
