HVAC Business Valuation

HVAC businesses are typically priced on one of two earnings figures depending on size: Seller's Discretionary Earnings (SDE) below roughly $1M, and EBITDA above. Applied to hvac specifically, the base multiple ranges are 3x–4.5x SDE and 5.5x–8.5x EBITDA. Where inside that range your business trades is decided by a handful of specific, buyer-visible factors.

Since roughly 2018, private-equity-backed platforms have been building regional HVAC roll-ups aggressively. Wrench Group, Apex Service Partners, Sila Services, Ned Stevens, and Redwood Services are among the platforms most active in the sub-$5M-revenue Main Street segment. Multiples for well-run HVAC businesses with a maintenance-contract book have moved meaningfully higher — 6–8x EBITDA is common for anything above $1M in EBITDA with recurring revenue over 40%.

HVAC valuation drivers

Industry sets the base range. These specific business-level factors move you up or down inside it.

Maintenance agreement penetration

Percent of customer base on a recurring maintenance contract. Buyers pay premium multiples above ~40%.

Average revenue per truck / tech

Annualized productivity. $600K–$800K/year per fully utilized service truck is the benchmark for a top-quartile operator.

Service call conversion rate

Percent of diagnostic calls that convert to a repair or replacement. Above 60% is strong.

Average ticket size

Blended average of service, repair, and install revenue per completed job. Rising ticket is a leading indicator of team quality.

Deal structure

How hvac deals close

Most sub-$3M-revenue HVAC deals close as SBA-financed asset purchases with 10–15% seller notes. Above $1M EBITDA, structures shift toward PE-platform acquisitions with rollover equity for owners staying involved, and 12–24-month transition consulting agreements.

Common questions

HVAC valuation FAQ

How is my HVAC business valued?

Below roughly $1M in Seller's Discretionary Earnings (SDE), most HVAC businesses are priced on an SDE multiple — typically 3.0–4.5x, moving to the higher end for operators with 40%+ maintenance-contract revenue and low owner dependence. Above $1M in EBITDA, buyers switch to EBITDA-based pricing at roughly 5.5–8.5x for well-prepared businesses.

How long does it take to sell an HVAC business?

From engaging a broker to a signed purchase agreement, plan on 6–9 months for a Main Street HVAC deal (sub-$5M revenue). SBA-financed deals add 60–90 days to the close because of lender underwriting. Institutional deals with PE-backed acquirers typically move faster once an LOI is signed.

What drives higher multiples for HVAC businesses?

Four factors move multiples materially: (1) maintenance-agreement penetration above 40%, (2) a general manager or service manager who runs day-to-day operations, (3) three years of accrual-basis financials with clear add-backs, and (4) commercial-service revenue mix (typically higher-margin than residential).

Should I sell to a private equity platform or a self-funded searcher?

PE platforms typically pay higher headline multiples but expect the owner to roll equity and stay involved 12–24 months. Self-funded searchers pay 20–30% less on the top-line multiple but structure clean, SBA-financed exits where the seller can walk away in 90 days. The right answer depends more on your post-close life plan than on the raw dollar amount.
