How Much Do HVAC Business Owners Make?

How HVAC income is actually quoted

HVAC companies are priced and discussed in seller’s discretionary earnings — net profit with the owner’s compensation, personal expenses, interest, depreciation, and one-time items added back. Single-location residential shops typically transact somewhere in the 2.5x–4x SDE range, with larger commercial-weighted companies valued on EBITDA and clearing more. The detail is in our HVAC business valuation page.

What matters for the income question is that SDE is not take-home pay for most buyers. If the seller was also the lead installer, the on-call diagnostic tech, and the person quoting every replacement, then a chunk of that SDE is compensation for three jobs. Replacing them costs $80,000–$160,000 depending on how much of the field work you personally intend to do. Model that as a permanent cost from day one, then service the acquisition debt out of what remains. See SDE vs EBITDA for why the two frames give such different answers.

Earnings by crew size

The bands below assume residential service and replacement work, a stabilized customer base, and a market-rate wage already deducted for any role the owner is not personally filling.

• Owner-operator, one truck. Revenue of $250,000–$450,000 and owner earnings of $70,000–$130,000. Low entry cost and no management overhead, but the owner is the capacity: a broken wrist stops revenue, and the business rarely sells for more than trucks, tools, and the customer list.
• Small shop, 2–3 trucks. Revenue of $600,000–$1.4M and SDE of $110,000–$250,000. The hardest size to run. Large enough to require dispatch, a real accounting system, and someone answering phones during peak, not yet large enough to pay for a manager. Most owners here still turn wrenches on the heaviest weeks.
• Established shop, 4–6 trucks. Revenue of $1.5M–$3M and SDE of $200,000–$450,000. This is the core of the acquisition market and the first size where a service manager genuinely pays for themselves. Enough technicians to absorb an absence without cancelling calls, which is what makes the earnings durable.
• Multi-crew company, 10+ trucks. Revenue of $3.5M–$10M and SDE of $400,000–$1M or more. Overhead spreads efficiently and the maintenance book becomes a real asset, but recruiting is a permanent function and one bad install season can consume a year of margin in warranty callbacks.

The cost structure

As a share of gross revenue, a stabilized residential HVAC shop generally runs roughly:

• Field labor, burden, and benefits: 25–33%. The defining line. Technician wages have risen faster than ticket prices in most markets, and the burden — payroll taxes, workers’ compensation at trade rates, health cover — adds meaningfully on top of the base wage. Confirm the seller’s numbers include burden, because many owner-prepared P&Ls do not.
• Equipment and materials: 28–38%. Higher on replacement-weighted work, lower on service-weighted. Distributor pricing depends on volume and relationship, so verify the shop’s actual buying terms rather than assuming list.
• Vehicles, fuel, and tools: 5–9%. Includes the replacement schedule. Check the fleet’s age — a set of trucks all past 200,000 miles is a capital-expenditure catch-up you inherit at close.
• Office, dispatch, and admin payroll: 7–12%. Add this back out if the seller’s spouse has been running the office unpaid, which is extremely common in this category and materially overstates the reported profit.
• Marketing and lead generation: 4–10%. Wide range for a real reason. A shop with a mature agreement book and a review presence spends near the bottom; one dependent on paid search and lead-aggregator fees spends near the top and earns less per call.
• Insurance, licensing, warranty, and callbacks: 3–6%. Callback cost is the honest quality measure. Ask for the callback rate as a percentage of installs and treat a vague answer as a finding.

Why the maintenance book is the whole game

Maintenance agreements rarely look impressive in isolation — the direct margin on a tune-up is thin. Their value is structural. They fill spring and fall when the phone stops ringing, they put a technician in front of aging equipment twice a year, and those visits are where replacement sales originate. A shop with 150 agreements per truck has predictable revenue and a pipeline; a shop with 20 has a phone number and a marketing bill.

When you are evaluating an acquisition, count agreements and check the renewal rate rather than accepting a headline number. Ask how many are paid monthly versus annually, how many renewed last cycle, and whether the list is in software you can actually export. An agreement book that exists only in the departing owner’s head is not an asset you are buying.

Worked example: a six-truck residential shop

The shop runs six trucks — four service, two install — and reports $2,400,000 of revenue, which is $400,000 per truck and squarely healthy. Mix is roughly 55% replacement, 35% service, 10% maintenance agreements, with about 720 active agreements on the book.

Costs: field labor with burden $720,000 (30%), equipment and materials $792,000 (33%), vehicles and fuel $156,000, office and admin payroll $216,000, marketing $144,000, insurance, licensing and warranty $108,000, rent and general overhead $96,000. Total $2,232,000, leaving about $168,000 of net profit. Add back the owner’s $95,000 salary, $22,000 of vehicle and discretionary items, and $19,000 of depreciation, and SDE is roughly $304,000.

Now the buyer-specific adjustment. The seller personally quotes every replacement job, which is the highest-value sales function in the business. If you will not do that yourself, budget a comfort adviser or sales manager at roughly $85,000 all-in, and realistic owner earnings land nearer $219,000 before debt service. On an SBA acquisition loan at a 3.2x SDE price of about $970,000, annual debt service in the neighborhood of $130,000–$145,000 leaves the working owner roughly $75,000–$90,000 in year one — a fair outcome, but a very different number from the $304,000 on the listing.

The upside lever is the agreement book, not the price sheet. Moving from 720 agreements to 1,100 across two seasons adds modest direct revenue but meaningfully lifts shoulder-season utilization and replacement pipeline — and because value tracks SDE, every durable dollar added there is worth roughly three at exit.

Before you rely on any of this

These are orientation ranges, not a forecast. Before you bid, get three years of tax returns and reconcile them to the P&L, pull revenue and job counts month by month to see the seasonal shape rather than an annual average, confirm technician license status and who holds the qualifying license for the company, count and age the agreement book out of the field-service software, and get your own insurance quote rather than assuming the seller’s premium transfers.
