Why HVAC Is One of the Best Businesses to Buy Right Now
Not every industry is worth your time as an acquisition target. HVAC is. Here's why serious buyers keep coming back to it.
Non-Discretionary Demand
When AC dies in July, nobody waits. Consistent revenue regardless of economic conditions.
SBA financeable
Stable cash flow and tangible assets make HVAC a lender favorite. As little as 10% down.
Recurring Revenue
Maintenance contracts create predictable monthly cash flow baked into the business model.
Recession-Resistant
People cancel subscriptions before they go without heat or air. HVAC is essential.
Retiring Owners
Thousands of baby boomer owners hitting the market with no succession plan. Opportunity is real.
No License Required To Own
You hire the technicians. The owner's job is building systems and growing revenue.
What Makes a Good HVAC Business to Buy
Not every HVAC business is worth buying. Here's what separates a great acquisition from a headache.
LOOK FOR THESE
Strong Recurring Revenue - Maintenance contracts with high renewal rates
Stable Technician Team - Techs and dispatcher who plan to stay
Stable Technician Team - Techs and dispatcher who plan to stay
Clean 3-Year Financials - Tax returns that match the P&Ls.
Strong Online Reviews - 150+ Google Reviews with High Rating
WALK AWAY FROM THESE
Revenue Concentration - One Client = 40%+ of Revenue
Owner is the business - No management layer, all relationships personal
Aging, Neglected Fleet - Trusts due for replacement in year one
Declining Revenue - Two or More Years of Downward Trend
Seller Pressure - Seller wants to close fast.
How to Value an HVAC Business
HVAC businesses are typically valued as a multiple of EBITDA (earnings before interest, taxes, depreciation, and amortization) or seller's discretionary earnings (SDE), depending on the size of the business.
For smaller businesses — those under $1M in revenue — SDE multiples are most common. You'll typically see deals in the 2x to 3.5x SDE range, though businesses with strong recurring revenue, a stable team, and clean financials can command higher multiples.
For larger businesses — $1M to $5M in revenue — buyers and sellers shift toward EBITDA multiples, which typically range from 3x to 5x for well-run operations with recurring service contract revenue and professional management.
DRIVES VALUATION UP
- High % of recurring contract revenue
- Stable team, low technician turnover
- Strong Brand in defined territory
- Clean, organized financials
DRIVE VALUATION DOWN
- Revenue from one or two clients
- Owner is the primary technician
- Aging fleet needing replacement
- Declining revenue trend
The SBA sweet spot. Most HVAC acquisitions in the $500K–$2.5M range are financed with an SBA 7(a) loan. With 10% down, the remaining 90% is financed over 10 years. Run the debt service coverage ratio (DSCR) before you commit — you want to see the business generate at least 1.25x the annual loan payment in free cash flow.
How to Finance an HVAC Acquisition
Financing is the step that stops most buyers — not because it's impossible, but because they don't understand their options. Here's a quick breakdown.
SBA 7(a) Loan — the most common path. SBA loans require as little as 10% down, offer repayment terms up to 10 years, and the rates are competitive. Lenders care about the business's cash flow and your ability to manage — not your HVAC certifications. You'll need clean personal financials, a credit score of 680 or above, and some management experience.
Seller financing — the underused tool. Ask the seller to carry a note for 10–20% of the purchase price. This signals that they believe in the business's continued performance, reduces your out-of-pocket at close, and can bridge the gap between SBA financing and the full purchase price. Many sellers, especially those retiring without a succession plan, will consider it.
Equity partner. If you don't have the 10% down payment or want to reduce your personal risk, bringing in an equity partner is worth considering. You give up a portion of ownership in exchange for capital. The right partner can also bring operational experience or lender relationships.
