Who we insure

The coverage a two-van residential shop needs looks nothing like what a commercial mechanical contractor carries into a GC's job trailer. Start with the work you actually do.

Residential HVACService calls, change-outs, maintenance plans and the after-hours calls that come with them. Commercial HVAC & mechanicalRooftop units, controls, tenant build-outs and the subcontract agreements that come with insurance requirements attached. Commercial refrigerationWalk-in coolers, reach-ins and ice machines for the restaurants and grocers that call you at 2 a.m. Independent HVAC technicians1099 techs and one-truck operators who need their own liability before a bigger shop will let them on a job.

What HVAC insurance actually covers

An HVAC company typically needs general liability, workers' comp, commercial auto and tools coverage first, then adds an installation floater, pollution liability, bonds and an umbrella as the work grows. The right mix depends on whether you're in homes or on commercial roofs, whether you install or mostly service, and how many people you put in vans.

Here's the kind of trouble those policies exist for:

• A furnace you installed starts a problem months later. Completed operations coverage, part of most general liability policies, is meant for damage that shows up after you've finished the job.
• A condensate line backs up. An attic air handler's drain pan overflows and stains two bedroom ceilings before anyone notices.
• A torch starts something. Brazing a line set inside a wall cavity scorches the framing behind it.
• A tech gets hurt. A ladder slips on a wet roof edge, or a summer attic sends someone to urgent care with heat exhaustion.
• The van gets hit, or broken into. A rear-end crash on the way to a no-cool call, or a smashed window and a missing set of digital gauges.
• New equipment walks off. A condenser delivered to a new-build site Friday is gone Monday morning.

Whether a policy pays any one of these depends on its wording, its exclusions and the facts of the claim. That's why we read the forms, not just the price. Get a quote for your HVAC business →

Your license may decide your minimums

Some states tie an HVAC contractor license directly to insurance: you file proof of general liability, a bond or workers' comp coverage with the licensing board before you can work. Other states leave HVAC licensing to cities and counties, and each one sets its own rules.

That means two shops of the same size can need different paperwork just because they work on different sides of a state line. Our HVAC license requirements by state guide covers the patterns, and each of our 28 state pages explains what that state's license asks you to carry.

Residential and commercial work need different paperwork

Homeowners rarely ask to see your insurance. Property managers and general contractors almost always do, and they want it in a specific shape.

On a residential change-out, your exposures are mostly inside someone's home: the attic, the basement, the flue, the gas line, the family living there. The questions that matter are about completed operations, carbon monoxide wording in your liability policy and whether your techs are trusted in customers' houses.

On commercial work, the paperwork arrives before the job does. A subcontract may require:

• additional insured status for the GC and the owner, often for completed operations too
• a waiver of subrogation on your general liability, auto and workers' comp
• primary and non-contributory wording
• $2 million or more in total limits, which usually means an umbrella
• a performance or payment bond on public and larger private jobs

If you do both kinds of work, your policies have to satisfy the stricter set. Our commercial HVAC page and certificate guide explain each request in plain terms.

Your exposure changes with the season

HVAC work runs on two peaks. Cooling season loads your schedule with no-cool calls, attic work in triple-digit heat and new-system installs. Heating season brings furnace starts, cracked heat exchangers and the no-heat call at 11 p.m. that someone has to take.

Both peaks change your insurance picture. You add techs and vans right before each one, which is when an outdated auto schedule or a low payroll estimate catches up with you at audit. Heating season puts combustion appliances and venting at the center of your liability exposure. Cooling season puts more people on roofs and in attics, which is where many workers' comp claims start.

A good time to review coverage is a month before each peak, not in the middle of it. Get a quote for your HVAC business →

What drives the price of HVAC insurance

What you pay depends on your payroll by class code, your annual revenue, your mix of installation and service work, residential versus commercial jobs, the vans you run, your claims history and the limits you pick. Install-heavy shops usually carry more completed-operations exposure than service-only shops, and commercial work tends to come with higher limits and more paperwork.
