Selling to Private Equity: What Happens to Your HVAC Company's Insurance Program

The insurance file is one of the first things a private equity buyer opens, and for most HVAC owners it's the least prepared part of the sale. Private equity HVAC insurance doesn't transfer clean at close: the buyer diligences your loss history and workers comp mod, and you buy tail coverage on your claims-made lines. This guide walks the insurance side of the deal, from the letter of intent to the months after close.

What happens to your private equity HVAC insurance in a sale?

In a private equity HVAC insurance transaction, the deal structure decides what happens to your policies. A stock sale keeps the legal entity intact, so most coverage stays in force if the carrier consents to the change in control. An asset sale works differently: your policies stay behind, and the buyer runs the operation under its own program. Either way, the insurance work spreads across the timeline, and every stage has an owner.

Anti-assignment and change-in-control clauses sit in almost every commercial policy, so even a stock sale needs carrier notice and sign-off. The table below maps who does what, from the letter of intent (LOI) through the months after the deal closes.

What does the buyer's insurance due diligence review?

A private equity buyer's insurance due diligence pulls your last five years of loss runs (the carrier's claims record) and your workers compensation experience modification rate (EMR). It also reviews open claims and their reserves, plus proof that your certificates of insurance (COI) and any wrap-up programs stayed compliant. Marsh describes its own insurance diligence as a review of the target's recent claims experience and an estimate of the recurring and one-off insurance costs the buyer will carry, feeding those figures into the deal's financial model. That number matters to your price, because insurance cost is an operating expense inside earnings before interest, taxes, depreciation, and amortization (EBITDA), so a program that's underpriced, or carrying claims nobody reserved for, overstates the earnings a buyer pays a multiple on.

Open claims matter more than most owners expect. A workers comp claim carrying an inflated reserve pushes your EMR up at each rating, and in a stock deal that mod can combine with the buyer's other companies after close. Acquirers model this carefully, because a higher combined mod raises workers comp premium across the whole platform.

Here's how that plays out in a real review: a $14 million HVAC company looked clean on the surface, but its broker had never flagged two open workers comp claims sitting with reserves high enough to push the experience mod past 1.10 at the next rating. The buyer used it to hold back part of the price until the reserves closed. An owner who reads the mod worksheet a year early can dispute stale reserves before an acquirer ever sees them.

What is reps and warranties insurance in the deal?

Representations and warranties (R&W) insurance covers the buyer when the seller's promises in the purchase agreement turn out to be wrong after closing. Say you represented that every workers comp claim was disclosed, and then a big one surfaces post-close. The R&W policy pays the buyer instead of clawing that money back from you. In a PE roll-up, the insurance program gets standardized fast, and R&W is now routine because it lets the seller keep more proceeds at close.

Pricing runs about 2.5% to 3% of the coverage limit, down from roughly 5% in early 2022, per CBIZ. The retention is the piece the buyer absorbs first. On these deals it lands near 0.5% to 1% of enterprise value, and carriers now write policies on transactions as small as $25 million, which pulls a lot of mid-size HVAC sales into range.

Do I need tail coverage on my claims-made policies?

Yes, on any claims-made line you carry. Errors and omissions (E&O), employment practices liability (EPLI), directors and officers (D&O), and cyber all stop covering new reports the moment the policy cancels at close. Tail coverage, formally an extended reporting period (ERP), holds that reporting window open for claims tied to work you did before the sale. Buyers routinely require it, because a design error or a wrongful-termination suit can surface years after the deal.

An ERP on claims-made lines usually costs 100% to 300% of the expiring annual premium, and it typically runs five to six years to match the deal's survival periods. The buyer often shares that cost, and you negotiate the split in the purchase agreement. Your general liability and commercial auto sit on an occurrence basis, so they already cover past work without a tail. The line owners forget most often is errors and omissions coverage on design-build work.

A broker preps this by binding the tail ahead of cancellation and lining up the R&W placement while the deal's still in diligence. Coverwatch handles that timing for HVAC clients, so the tail is in force the day the entity changes hands and the buyer has one less holdback to argue for.

How a clean loss history lifts your sale price

A clean loss history lifts your HVAC company's sale price. Insurance cost sits inside EBITDA, and buyers pay a multiple of it, so a mod below 1.0 and five clean years of loss runs cut the program cost the buyer inherits and raise the earnings they're buying. On a business valued at, say, 8 times EBITDA, every $50,000 of premium you shave is worth roughly $400,000 at sale.

Private equity add-on acquisitions of HVAC companies surged through 2025, per S&P Global Market Intelligence, as platforms roll up independent shops. Buyers underwrite the same numbers your carrier does, so the file that earns you good renewal terms also reads well in diligence.

After close, your program stops being its own policy and the entity moves onto the platform's master program. A company that ran on guaranteed-cost coverage often shifts to a large-deductible or captive structure, where the group self-funds routine losses. That's the buyer's model, and clean loss runs make your operation cheap to fold in.

The insurance side of selling your HVAC business rewards the owner who starts a year early, and the HVAC company insurance program rewards the same discipline at renewal, 90 days out. Clean up the mod, close stale claims, and know your loss runs before a buyer asks. Coverwatch preps HVAC programs for diligence and places the tail and R&W coverage as part of its flat-fee contractor insurance practice, and the HVAC contractor insurance guide covers the lines underneath it.
