Mississauga homeowners replace furnaces for two reasons: the old one failed (often on the coldest day of the year), or they are planning ahead and want to avoid that scenario. Either way, the installation process is the same - and choosing the right contractor makes the difference between a smooth same-day experience and a costly, permit-deficient installation that can affect your home insurance.

The Furnace Installation Process with EcoFrost
Free in-home estimate
A certified EcoFrost technician visits your home, performs a Manual J heat load calculation, inspects your existing ductwork and venting, and provides a written quote for 2 to 3 options at different price points. No pressure, no obligation.
Permit application
EcoFrost applies for the required City of Mississauga mechanical permit. This is included in your quote. Permit turnaround is typically 1 to 3 business days for standard replacements.
Equipment delivery and installation
Our installation team arrives with your new furnace and all required materials. The old furnace is safely disconnected, removed, and responsibly disposed of. The new furnace is installed per manufacturer specs and Ontario Building Code, including proper venting and gas connections.
City inspection and certification
A City of Mississauga inspector verifies the installation. EcoFrost coordinates this appointment. You receive a stamped permit and TSSA compliance certificate - important documentation for home insurance and future resale.
Warranty registration and homeowner walkthrough
We register your manufacturer warranty, walk you through the system controls and filter schedule, and answer all questions. You receive a complete installation package including specs, warranty cards, and permit.
