Richmond Hill’s Oak Ridges Moraine properties are one of the few parts of the GTA where geothermal ground-source heat pumps are genuinely common, and a lot of HVAC companies simply don’t have technicians trained on them. If that’s your system, the standard “how to choose a contractor” checklist needs one more question added.
Ask If They Actually Service Geothermal Systems
If your property runs geothermal, ask directly whether the company has technicians specifically experienced with ground-source systems — not just general HVAC licensing. A company unfamiliar with geothermal may misdiagnose a loop-side issue as something else entirely, or simply be unable to service it.
Ask About TSSA Licensing
In Ontario, anyone working on gas-fired appliances — including most furnaces — is legally required to hold certification through the Technical Standards and Safety Authority (TSSA). Ask directly whether the technician coming to your home is TSSA-certified.
Understand How They Price Repairs
Some companies quote an hourly rate that can balloon once they’re on-site. Others, like us, quote a flat rate for the job before any work starts, so you know the cost upfront regardless of system type.
Check Their Actual Response Time
“24/7 emergency service” means different things to different companies. Some route your call to an answering service that takes a message; others have a live dispatcher who can tell you, on the spot, when a technician will actually arrive.
Ask What Brands and System Types They Service
A company that only knows standard furnace brands may struggle with a geothermal heat pump system entirely. Look for technicians explicitly experienced with both.
Red Flags to Watch For
- Reluctance to confirm geothermal experience if that’s your system.
- No licence number provided when asked.
- No firm price before work begins.
- Pressure to replace an entire system before a proper diagnosis has been done.
- No local presence in Richmond Hill — a company with no actual local trucks can’t reliably hit a fast response time.
Choosing the right company up front saves you money and, in an emergency, saves you time. If you’re comparing options in Richmond Hill, ask us these same questions — we service standard furnaces and geothermal systems alike, and we’re happy to answer before you book.
