Key facts
- General liability is the base policy, and most builders and property managers ask for a certificate before you start.
- A standard liability policy often excludes pollution, so refrigerant, mould and similar claims need a separate look.
- Auto policies generally do not cover the tools and equipment in your van.
- Work done months ago can still lead to a claim. Completed operations coverage matters.
- Your gas and heating certifications affect what insurers will offer.
Risks HVAC contractors face
- Fire and heat. A poorly installed furnace, flue or heater can start a fire, sometimes long after the job is done.
- Water damage. Leaking condensate lines, frozen pipes and failed connections can damage a customer's home.
- Carbon monoxide and gas. Claims can follow an install or repair on a gas appliance.
- Refrigerants and contamination. Releases, mould and poor air quality can lead to pollution-related claims.
- Theft. Tools, meters, recovery machines and stock are attractive targets, especially in vans.
- Vehicle accidents. Technicians drive all day between customers.
- Seasonal peaks. Winter and summer rushes mean more jobs, more subcontractors and more risk.
- Property damage on the job. Ladders, ducts and equipment can damage floors, walls and roofs.
Coverages to consider
- Commercial general liability. Pays for injury and property damage claims and legal defence. Many contractors choose $2 million because customers ask for it.
- Products and completed operations. Covers claims that arise after the work is finished.
- Contractor's pollution liability. Covers cleanup and claims from covered pollution events that a standard liability policy may exclude.
- Tools and equipment. Covers tools, gauges, vacuum pumps and diagnostic equipment at job sites, in vehicles and in storage.
- Installation floater. Covers furnaces, air conditioners, ducts and materials before you hand the job over.
- Commercial auto. Covers work vans and trucks for business use. See our commercial auto for trades page.
- Commercial property. Covers your shop, warehouse, stock and office contents.
- Business interruption. Replaces lost income if a covered loss stops your business.
- Equipment breakdown. Covers shop machinery and testing equipment that fails suddenly.
- Professional liability. Covers claims about design, sizing or system recommendations that cost a customer money.
- Cyber liability. Covers costs after a breach of customer or payment data.
- Umbrella liability. Adds higher limits over your liability and auto policies. See our umbrella page.
Certificates and subcontractors
General contractors and property managers usually require a certificate of insurance. They may also ask for additional insured status, a waiver of subrogation and a minimum liability limit. Set these up before you bid so a certificate request does not slow you down. If you hire subcontractors, collect their certificates and check the limits. If a sub has no insurance, you may end up carrying the risk.
Licences and training
Insurers often ask whether your technicians hold the certifications required for their work, such as gas technician certification regulated by the Technical Standards and Safety Authority (TSSA). We can point out what an insurer will want to see, which helps you avoid delays.
Seasonal considerations
Heating and cooling businesses often see uneven revenue through the year. Tell your insurer about seasonal payroll, temporary crews and extra vehicles. Store stock safely, and ask us how policies treat equipment left on job sites overnight.
What insurers ask HVAC contractors
- Split between residential, commercial and new construction work
- Whether you install gas appliances, and whether you work on commercial rooftop units

- How you store stock and secure tools
Example scenarios
Questions Ontario clients ask
- How much does HVAC contractor insurance cost in Ontario?
- It depends on revenue, payroll, the mix of residential and commercial work, claims history and the limits you choose. We compare 20+ insurers and specialty markets to get real numbers for your business.
- Do I need pollution liability as an HVAC contractor?
- Often yes, or at least you should review it. Standard liability policies commonly exclude pollution, so refrigerant, mould and similar claims may need separate coverage.
- Does my van insurance cover my tools?
- Generally no. Tools and equipment need their own coverage.
- Do I need insurance if I work alone?
- Yes. Customers, property managers and builders often require liability coverage, and one claim can cost far more than a year of premiums.
- Can I use my personal vehicle for HVAC work?
- Only if the insurer knows about it and rates it for business use. Otherwise a claim may be questioned.
- What about apprentices and helpers?
- Tell us how many people work with you, whether they are employees or subcontractors and what they do. It changes the price and the wording.
- Can you get me a certificate the same week I ask?
- Once the policy is in place and the wording is set up, we can usually turn certificates around quickly.
