A new furnace is one of the biggest comfort investments you'll make in your home, and the quality of the installation matters as much as the brand on the cabinet. We size every system with a proper heat-loss calculation rather than guessing from the old unit, then install it with custom-fabricated plenums and transitions so air moves quietly and efficiently.
We install 96–98% AFUE condensing furnaces, two-stage and modulating models, and variable-speed blowers that make a noticeable difference to comfort and noise. Every installation includes permits, TSSA-compliant gas piping, new venting, condensate drainage, a programmable or smart thermostat, and full cleanup — the photo on this page is a real basement install by our team.

Frequently asked questions
How long does a furnace installation take?
Most straight swaps are completed in one day. Installations that require new venting routes or major duct changes can take two days.
Are there rebates for a new furnace?
Rebates change often. Enbridge and federal programs mostly target heat pumps and insulation, but some high-efficiency equipment qualifies. See our Financing & Rebates page or ask during your estimate.
