FAQ
Common questions
When should I replace my furnace?
Most gas furnaces last 15-20 years. If yours is 15+ years old, has rising repair costs, or your heating bills are climbing year-over-year, replace. We offer free energy-efficiency comparisons.
Are heat pumps worth it in Ontario?
Modern cold-climate heat pumps work down to -25°C and qualify for the federal Greener Homes Grant ($5,000) plus Ontario rebates. For most GTA homes, a heat pump + small backup gas furnace is the most efficient combo.
Do you install boilers?
Yes — combi-boilers (heat + domestic hot water in one unit) and standalone boilers for radiator, baseboard, and in-floor heat. TSSA-licensed installation with manufacturer warranty.
