Buying an HVAC Business

At a Glance

How HVAC Businesses Make Money

When a seller tells you the business is 'residential,' that's not an answer — it's a starting point. HVAC revenue typically splits across service and maintenance, replacement installs, and (sometimes) new construction or remodel work, and each line behaves very differently in margin, durability, and how a strategic acquirer would value it. Pure service-and-replacement shops generally command higher multiples than mixed shops carrying meaningful new construction.

What You're Actually Buying

What you're really buying in a small HVAC deal is rarely 'a business' in the systematized sense. At sub-$5M revenue, most shops haven't built durable recruiting or lead-gen infrastructure — what transfers is a phone number that rings, a Google footprint, trucks, and the technicians willing to stay. Confirm what's included on paper, but more importantly, confirm what's actually under the buyer's control after close.

What to Look At Before You Buy

These are the questions that separate a buyer from a future owner-operator who paid too much. HVAC's economics look clean on a P&L summary, but the operational truth lives one layer down — in how leads are generated, how technicians are classified, and whether the license walks out the door at close.

1. 01

   Who actually holds the contractor license — and can it transfer in 12 months?

   In many states, the HVAC license is tied to a named qualifying individual, often the seller. Recent SBA rule changes make it very hard to finance deals where the seller's personal license is required and transfer takes longer than a year. Confirm whether an employee qualifier exists, or whether you'll need to obtain the license yourself before close.

2. 02

   How is the revenue split between service, replacement, and new construction?

   'Residential' is not an answer. Service typically loses money but feeds installs at ~50% gross margin, while new construction is lumpier and lower-quality revenue. A pure service-and-replacement mix supports a higher multiple; meaningful new construction exposure should compress what you pay.

3. 03

   Are technicians W-2 or 1099 — and if 1099, why are margins so high?

   Trades shops running on 1099 labor often show inflated cash flow because they're avoiding employment taxes, benefits, and workers' comp. They also face customer-leakage risk: if a 1099 tech leaves, the customer often follows. This is fixable in the deal — convert to W-2, recast the financials, take an indemnity — but only if you price it in.

4. 04

   What does a real lead actually cost — and where do they come from?

   Google Local Service Ads that delivered HVAC leads at $15–$25 a few years ago are now running $45–$70. Get a clear breakdown of inbound call volume, GMB performance, review count, and any reactivation potential in the customer database. The marketing footprint is often the real moat.

5. 05

   Is revenue per technician healthy — or is the shop overstaffed?

   A reasonable benchmark for truck-based service work is roughly $400K–$500K in revenue per technician per year. A $1.2M shop with nine techs is a different story than a $1.2M shop with five. Below-benchmark productivity usually means dispatch, lead flow, or pricing problems you'll inherit.

What a Fair Price Looks Like

HVAC multiples have expanded as private equity and search funds have crowded in, but the price an individual buyer should pay still depends heavily on size, mix, and operational maturity. A useful sanity check from operators: at the small end, paying close to 1× revenue is generally too much — closer to 0.5× revenue is where the math usually works for an individual buyer without a strategic angle.
