What questions should I ask an HVAC contractor

Ask about licensing, experience, and detailed project scope to ensure you're hiring a qualified contractor who will complete your HVAC work safely and properly.

Licensing and Insurance Questions
Start with the most important qualifications. Ask if they're TSSA licensed (required for gas work in Ontario), request their license number, and verify they carry WSIB coverage and liability insurance. A legitimate contractor will readily provide this information and won't hesitate when you ask to see proof of insurance.

Experience and References
Inquire about their experience with your specific type of project - furnace installation, heat pump systems, or ductwork modifications all require different expertise. Ask for recent references from similar jobs and whether they specialize in residential or commercial work. Contractors with 10+ years of experience typically handle unexpected issues more effectively than newer companies.

Project Details and Timeline
Get specifics about the work scope, including what equipment they'll install, whether permits are required, and realistic timelines. Ask about TSSA permit requirements for gas appliances and who handles the permit application process. Discuss what happens if they encounter unexpected issues like asbestos insulation or structural modifications needed for new equipment.

Pricing and Warranty Structure
Request detailed written quotes that break down equipment costs, labor, permits, and any additional fees. Compare not just total prices but warranty coverage - quality contractors typically offer 2-5 year warranties on installation and will explain manufacturer equipment warranties. Ask about payment schedules and avoid contractors demanding large upfront payments.

Emergency Service and Maintenance
Find out if they provide ongoing service and emergency repairs, especially important for heating systems in Ottawa winters. Ask about annual maintenance programs and response times for emergency calls. Contractors who service what they install typically provide better long-term value than install-only companies.
