Complete Furnace Services
Whether your furnace is 2 years old or 20, we diagnose, repair, and replace all makes and models — quickly and correctly.
Furnace Installation
Upgrading to a high-efficiency furnace is one of the best investments you can make for your home's comfort and energy bills. We size the system correctly for your home, handle all ductwork connections, and ensure a clean, code-compliant installation.
Furnace Repair
No heat, short cycling, strange noises, or rising gas bills? Our technicians carry the most common parts on the truck — most repairs are completed in a single visit. We service all major brands including Carrier, Lennox, Trane, Goodman, and more.
Furnace Tune-Up & Maintenance
An annual tune-up keeps your furnace running efficiently, extends its lifespan, and catches small issues before they turn into expensive breakdowns — especially important before Ontario's cold season hits.
Emergency Furnace Service
A furnace failure in January doesn't wait for business hours. We prioritize emergency heating calls and respond fast across our entire service area — because your family's comfort and safety come first.

Furnace FAQs
How long does a furnace installation take?
Most standard furnace replacements take 4–6 hours. We'll give you a clear time estimate when you book.
What brands do you install and service?
We work with all major brands — Carrier, Lennox, Goodman, Trane, York, Napoleon, and more. We'll recommend what fits your home and budget.
Should I repair or replace my furnace?
If your furnace is under 10 years old and the repair cost is under half the replacement cost, repair usually makes sense. We'll give you an honest recommendation either way.
Do you offer financing?
Not yet, but it's coming! We're working on making financing available so that upgrading your heating and cooling system is as stress-free as possible. In the meantime, please don't hesitate to reach out — we're happy to discuss your options and find a solution that works for your budget.
