“Most companies sell you a box. We start with the house.”
— The way we workFurnace installation & repair
High-efficiency gas furnaces sized by load calculation. Repair-first: if your unit has safe, economical life left, we fix it and say so.
Air conditioning
Central AC and ductless systems built for GTA humidity. Full diagnostics before anyone mentions replacement; most installs done in a day.
Heat pumps
Year-round heating and cooling in one system. Cold-climate models rated for Ontario winters, with rebate guidance included.
Boilers & hydronic heat
Boiler installs, repairs, and radiant floor retrofits. Quiet, even heat with no blown dust — a different kind of comfortable.
Hot water tanks & tankless
Endless hot water with a tankless upgrade, or a straightforward high-efficiency tank swap — sized to your household.
Indoor air quality
Humidifiers, air purifiers, and HRV/ERV ventilation. The temperature is only half the story; the air should feel good too.
Iron Shield maintenance plans
Seasonal tune-ups with free labour on covered repairs and transparent pricing. Small problems stay small.
Commercial HVAC
Rooftop units, make-up air, and service contracts for offices, retail, and restaurants — scheduled around your hours.

Asked often.
Do you repair systems, or only replace them?
We repair first. If your furnace or air conditioner still has safe, economical life left, we'll fix it and tell you so. Replacement only enters the conversation when the repair math stops making sense — and we'll show you that math.
How fast can you get a technician to me?
