How to Find a Reliable HVAC Contractor in Toronto — 2026 Guide
Choosing the wrong HVAC contractor in Toronto is an expensive mistake. Here is exactly what to check before you hire anyone.
5 Must-Check Criteria for Any Toronto HVAC Contractor
- TSSA Certification — In Ontario, all gas work requires a TSSA Gas Technician licence. Ask for the tech’s TSSA ID before any work begins. Never hire anyone who cannot provide it.
- Google Reviews — Verified — Look for 100+ Google reviews, 4.7+ stars, and specific details in reviews.
- Written Quote Before Work Starts — Any reputable contractor gives a written quote. Beware of verbal “diagnostic fee then we will see” approaches.
- Liability Insurance — Ask for a certificate of insurance. $2M+ liability coverage is standard for GTA HVAC contractors.
- Local, Established Business — A contractor with a local address, established website, and multi-year presence.
Red Flags to Avoid
- No TSSA licence number available
- Pressure to decide today on a new system
- Unusually low quote (often means unlicensed labour or inferior equipment)
- Cash only, no receipts
