Insureon median for HVAC businesses, updated August 2026
Insureon’s figures are medians for HVAC installation companies that apply for quotes through it, most with fewer than five employees, revenue of about $50,000 to more than $200,000 and five years or less in business. Its general liability figure assumes $1 million per occurrence, $2 million aggregate and a $500 deductible. Commercial auto is the largest line in its table, and a business owner’s policy bundles liability with property for firms that qualify. A contractor doing mostly residential maintenance agreements generally prices differently from one installing commercial rooftop units, and gas heating, refrigeration and claims history all move the figure. Florin, an independent broker that compares options from several insurers, can price your mix against these figures.
What moves your price
- Share of gas heating, commercial rooftop or refrigeration work
- Residential maintenance and replacements versus new construction
- Payroll and technician count
- Number of vans and drivers
- Carbon monoxide, fire or water claims in your loss runs
- Your state, limits and deductibles
Risks
The risks insurers price for
Carbon monoxide from a heating install
A furnace installed with a disconnected flue or a cracked heat exchanger missed on a service call can fill a home with carbon monoxide. The CDC reports more than 400 Americans die each year from unintentional, non-fire carbon monoxide poisoning, and such a claim can reach your liability policy years after the job.
Condensate and unit leaks
Insureon’s examples include an air conditioner that leaks and damages a client’s floors. A clogged condensate line in an attic air handler can stain the ceiling below.
Damage while moving equipment
Insureon lists damage to a home while moving a unit among typical HVAC claims, a risk on every replacement where heavy units are carried through finished rooms.
Advice and air quality claims
Insureon also lists claims over installation mistakes, energy efficiency recommendations and poor indoor air quality, which allege bad advice rather than physical damage.
Burns, strains and rooftop work
BLS says HVAC technicians have one of the highest rates of injuries and illnesses of all occupations, naming burns from electrical parts or chemicals and strains from heavy equipment, across about 440,900 jobs in 2025.
Coverage
Coverage to consider
General liability with completed operations
Pays for injury and property damage you cause to others, including carbon monoxide, fire and water claims that appear after a system is running, subject to its terms and any pollution exclusion.
How general liability works →Workers’ compensation
Covers technicians hurt by burns, shocks, falls from roofs and ladders or lifting condensers and furnaces. California requires it of every C-20 licensee, even with no employees.
How workers’ compensation works →Commercial auto
Covers service vans and trucks that carry crews, ladders and refrigerant cylinders. Insureon reports a median of about $286 a month for HVAC businesses.
How commercial auto works →Tools and equipment
Covers gauges, recovery machines, vacuum pumps and diagnostic tools. Insureon notes general liability does not cover your own tools and items worth more than $2,500 may need to be scheduled; it reports about $41 a month.
Installation floater
Covers condensers, furnaces and air handlers in your van or on site until the customer accepts the job.
Contractors pollution liability
Worth asking about for refrigerant releases, mold from condensate leaks and duct cleaning, which standard pollution exclusions may leave uncovered.
Cyber
HVAC firms that store customer card data for service agreements face data breach costs. Insureon reports a median of about $129 a month for HVAC businesses.
How cyber insurance works →Professional liability
Responds to claims over installation mistakes, energy efficiency recommendations and poor indoor air quality, which Insureon lists among HVAC claims.
How professional liability works →Rules
Requirements and filings
Federal refrigerant rules apply to every technician, and many states add license insurance minimums. These examples were checked October 2026; confirm your own state’s rules with its licensing board.
| Requirement | Applies to | What it means |
|---|---|---|
| Section 608 technician certification | Technicians who maintain, service, repair or dispose of equipment that could release refrigerant | Type I, II, III or Universal certification; credentials do not expire and supervised apprentices are exempt (EPA Section 608). |
| Venting prohibition | Anyone servicing, repairing or disposing of refrigerant equipment | Intentionally venting ozone-depleting refrigerants or their substitutes is prohibited (EPA Section 608). |
| Technology Transitions restrictions | New systems using higher-GWP refrigerants | EPA issued a final rule on May 26, 2026 reconsidering parts of these restrictions; check current rules by sector before quoting a replacement (EPA). |
| Class A contractor liability | Texas air conditioning and refrigeration contractors, any size unit | $300,000 per occurrence and $600,000 aggregate general liability (TDLR). |
| Class B contractor liability | Texas Class B, cooling to 25 tons and heating to 1.5 million BTU an hour | $100,000 per occurrence and $200,000 aggregate general liability (TDLR). |
| Public liability and property damage | Florida certified or registered air conditioning contractors | $100,000 public liability and $25,000 property damage (Florida Administrative Code rule 61G4-15.003). |
| Workers’ comp for C-20 contractors | California C-20 HVAC licensees | Required regardless of whether you have employees; a lapse suspends the license (CSLB). |
| Workers’ comp election | Texas private employers | Private employers can choose whether to carry workers’ comp (Texas Department of Insurance). |

How to lower the cost
- Test combustion and check for carbon monoxide on every gas appliance you install or service, and record the readings on the ticket.
- Install float switches or secondary drain pans on attic and closet air handlers.
- Keep copies of each technician’s Section 608 certificate and your recovery equipment records.
- Use fall protection and roof hatches for rooftop units, and train crews on ladder setup.
- Collect certificates of insurance from duct, electrical and crane subcontractors before they start.
- Bundle liability and property in a business owner’s policy if you qualify.
Before you start
What underwriters ask for
- License class and number, and the states you work in
- Split between residential service, replacements, new construction and commercial work
- Whether you do gas furnaces and boilers, commercial refrigeration, duct cleaning, sheet metal or crane lifts
- Payroll by role and subcontractor costs
- Certificates of insurance from your subs
- Vehicle and driver list with motor vehicle records
- Technicians’ Section 608 certifications
- Five years of loss runs, with details of any carbon monoxide, fire or water claims
Common questions
HVAC contractor insurance: questions
Does my HVAC business need EPA certification, or just my technicians?
EPA Section 608 certification is held by individual technicians who service equipment that could release refrigerant. Supervised apprentices are exempt, and the credentials do not expire.
Does general liability cover a carbon monoxide claim from a furnace I installed?
Bodily injury from your completed work is generally covered under the products and completed operations part of a general liability policy, subject to its terms and any pollution exclusion. Ask how your policy treats carbon monoxide before you buy it.
Do I need workers’ comp as a solo HVAC contractor in California?
Yes. The California license board requires C-20 HVAC contractors to carry workers’ comp even with no employees, and a lapse suspends the license.
How much liability insurance does a Texas HVAC contractor need?
TDLR requires $300,000 per occurrence and $600,000 aggregate for a Class A license, and $100,000 per occurrence and $200,000 aggregate for Class B. Commercial customers often ask for more; Insureon’s typical HVAC policy carries $1 million per occurrence.
Are refrigerant leaks covered?
Water damage from a leaking unit is usually a general liability claim, but a release of refrigerant itself may fall under a pollution exclusion. Contractors pollution liability is the policy built for that gap.
Are my gauges and recovery machine covered if they are stolen?
Not by general liability. A tools and equipment policy covers them, and Insureon reports a median of about $41 a month for HVAC businesses.
How much does an HVAC contractor bond cost?
The bond amount depends on your state or city, but you pay only a premium for it. Insureon reports a median of about $9 a month, or $112 a year, for surety bonds bought by HVAC businesses.
