What Insurance Types Are Needed For an HVAC Business?
Covers property damage and bodily injury from your HVAC work, including damage from installations, refrigerant leaks or equipment left in walkways. This is your most important coverage due to high claim frequency. | $1 million to $2 million per occurrence or $2 million to $3 million aggregate. | A tech's drill hit a hidden water line during an AC installation, flooding three floors. Water damage ($87,000), lost rental income ($23,000) and legal fees ($15,000) totaled $125,000—general liability covered everything. | |
Required by law in most states once you hire employees. Pays medical bills and lost wages for injuries like ladder falls, heat exhaustion, refrigerant exposure and back strains. | Your state sets the minimum amount. | An installer fell 12 feet from a ladder while mounting a condenser unit, breaking both legs plus his wrist. Between surgery, therapy and eight months of lost wages, the bill hit $176,000—workers' comp covered it all. | |
Covers your service vans and trucks since personal auto policies exclude business use and hauling equipment. Protects against vehicle damage, equipment theft and accidents your techs cause on the road. | $1 million combined single limit with comprehensive and collision. | A service van ran a stop sign rushing to an emergency call, causing a three-vehicle pileup. Medical bills, vehicle damage, destroyed equipment and a damaged storefront totaled $172,000—commercial auto paid all but a $1,000 deductible. | |
Protects you when clients claim your work wasn't done right, whether from sizing errors, bad installations or repairs that failed. Most commercial contracts require this. | $1 million minimum per claim. | A contractor installed an undersized AC in a medical office that couldn't hold temperature, spoiling $95,000 in medications. Fighting the lawsuit cost $47,000, the settlement was $110,000—professional liability covered the full $157,000. | |
Covers your specialized gear like recovery machines, vacuum pumps, manifold gauges and leak detectors when stolen, damaged or broken. This keeps you working when theft or damage strikes. | $15,000 to $30,000 based on your inventory. | Thieves smashed a van window and stole $18,500 in equipment overnight. The crew couldn't work for three days, losing $4,200 in jobs—tools insurance paid for everything within a week. | |
Pollution Liability Insurance | Covers EPA fines and cleanup costs from refrigerant leaks or accidental releases. Many commercial clients require this before you start work. | $500,000 to $1 million. | A tech accidentally released 180 pounds of R-22 during a chiller retrofit, triggering building evacuation. EPA fines ($42,000), cleanup ($33,000), lost business income ($28,000) and medical monitoring ($14,000) totaled $117,000—pollution liability covered all but a $2,500 deductible. |
HVAC Business Insurance Requirements
HVAC contractors face insurance requirements from state licensing boards, federal environmental regulations and commercial contracts. Requirements vary by state and contract type, with consequences for non-compliance including license revocation, EPA fines and contract termination.
(Get Covered)
Workers' Compensation Insurance | Required by law in most states once you hire employees. Penalties include fines up to $10,000 per employee, criminal charges, business license suspension and personal liability for all injury costs. HVAC work creates high injury risk from ladder falls, refrigerant exposure, heat exhaustion in confined spaces and lifting heavy equipment. | State minimums are based on payroll and industry classification. HVAC contractors typically pay $2 to $8 per $100 of payroll, varying by state and claims history. |
General Liability Insurance | Required by many states for HVAC contractor licensing. Texas requires $300,000 to $600,000 depending on license class, Washington requires $250,000 minimum, and Colorado requires $100,000 minimum. Commercial clients, property managers, general contractors and municipalities require proof of coverage before awarding contracts or issuing permits. | State licensing requirements range from $100,000 to $600,000. Commercial contracts typically require $1 million per occurrence and $2 million aggregate. High-value clients including hospitals, data centers and government facilities often require $3 million to $5 million in coverage. |
Contractor License Bonds | Required by most states for HVAC contractor licensing, with amounts set by state statute. Contractor license bonds guarantee you'll follow building codes, complete contracted work, pay suppliers and comply with regulations. Operating without required bonds results in license revocation, inability to pull permits and fines up to $5,000. | Bond amounts vary by state: Alabama ($20,000), Alaska ($25,000), Arizona ($9,000-$15,000 based on revenue), Arkansas ($10,000), California ($25,000), Idaho ($2,000), Maryland ($20,000), Minnesota ($25,000) and Washington ($15,000 for specialty contractors). Some states require separate refrigerant handling bonds. |
EPA Section 608 Certification | Required by federal law under the Clean Air Act for all HVAC technicians who maintain, service, repair or dispose of equipment containing refrigerants. EPA Section 608 certification is mandatory to legally work with refrigerants. Violations result in EPA fines, loss of certification and federal court appearances. | Technicians must pass EPA-approved exams for Type I (small appliances), Type II (high-pressure systems), Type III (low-pressure systems) or Universal (all types) certification. Certification never expires but must stay on file at your business location for three years after you stop operating as a technician. |
Commercial Auto Insurance | Required by law in 49 states for business-owned vehicles. Personal auto policies exclude commercial use, equipment transport and business-related accidents. HVAC contractors using vehicles for service calls, equipment delivery or transporting refrigerants must carry commercial policies. | State minimums vary from 25/50/10 to 30/60/25 split liability limits. Most commercial contracts and licensing boards require $1 million combined single limit to cover vehicle damage, equipment cargo and liability exposure. |
Pollution Liability Insurance | Required by commercial contracts involving refrigerant work on government projects or properties near waterways due to EPA regulations carrying fines up to $37,500 per day for improper refrigerant releases. Many general contractors, property management companies and municipalities mandate pollution liability coverage before allowing HVAC work. | Standard requirements range from $500,000 to $1 million per occurrence with $1 million to $2 million aggregate. Large commercial projects, government contracts and work near protected areas may require $2 million to $5 million to cover EPA fines, cleanup costs and environmental remediation. |
Commercial Property Insurance | Required by landlords for HVAC businesses leasing commercial warehouse or shop space and by lenders for financed properties. Lease agreements typically mandate commercial property coverage as a condition of occupancy to protect the landlord's investment. | Coverage amounts must equal replacement cost of building contents and business property, typically $100,000 to $500,000 depending on equipment inventory, refrigerant supplies and stored HVAC units. Landlords often require coverage matching one year's rent or estimated property value, whichever is higher. |
How To Ensure HVAC Business Insurance Requirements Are Met
HVAC contractors must prove insurance coverage to state licensing boards, commercial clients and property owners after purchasing policies. Follow these steps to obtain documentation, maintain compliance and avoid license suspension or contract delays.
(Get Covered)
- 1Request Certificates of Insurance and file required bonds
Request a Certificate of Insurance from each insurer immediately after purchasing coverage since most providers deliver COIs within hours via email or download. File your contractor license bond with your state licensing board by submitting the original bond document and paying the filing fee ($50 to $150 depending on state), as your HVAC license won't be issued or renewed without the filed bond on record.
- 2Verify coverage meets licensing and contract requirements
Review each COI to confirm policy limits satisfy your state's licensing requirements and client contract specifications. Check that general liability shows the required amount (Texas requires $300,000 to $600,000, Washington requires $250,000), workers' compensation meets state minimums, your contractor bond matches the mandated amount ($25,000 in California, $2,000 in Idaho) and your EPA Section 608 certification stays on file at your business.
- 3Add additional insured when contracts require it
Contact your insurer to add the property owner, general contractor or facility manager as an additional insured on your general liability policy when commercial contracts require it. This endorsement costs $25 to $100 per additional insured and processes within 24 to 48 hours because many general contractors won't allow you on job sites without this documentation.
- 4Submit proof to required parties before starting work
Provide certificates of insurance to commercial clients at least 48 hours before starting HVAC installation or service work, to your state licensing board when applying for or renewing your contractor license, and to landlords before signing leases. Keep your EPA Section 608 certification accessible since clients may request verification that technicians are federally certified to handle refrigerants, and municipalities may require proof of insurance before issuing permits.
- 5Update coverage and send renewals proactively
Set reminders 30 to 60 days before policy renewals to obtain updated COIs and avoid coverage gaps that could suspend your contractor license or halt projects. Send new certificates to active commercial clients, general contractors and your state licensing board annually, and update workers' compensation when hiring technicians, add vehicles to commercial auto coverage when expanding your fleet, and increase liability limits when contracts require higher amounts.
