Furnace Installation Cost, Timeline, and Permit Checklist in Durham Region
Replacing a furnace is a big decision that you usually make on a deadline. This guide explains what drives cost, how long an install really takes, what permits and inspections may be involved, and when a hybrid heat pump makes sense.
What affects the price
Most quotes combine the furnace, venting and gas connection, a properly sized ECM blower, a media filter cabinet, the thermostat, and any duct adjustments. Two-stage models usually deliver the best value. Modulating models are quiet and precise in larger or open layouts.
Costs vary with equipment efficiency, return-air upgrades, venting runs, and whether you add options like humidification or an HRV. We provide a written range after a short site review rather than guessing sight-unseen.
How long it takes
A straight furnace replacement with no duct changes typically fits in a single day, including removal, set, venting, gas, electrical, and startup. Add a second day if we are upsizing returns, adding a media filter cabinet, or integrating a smart thermostat and sensors.
Hybrid projects that add a heat pump are planned as a separate visit or a multi-day sequence so commissioning can be done carefully.
Permits and inspections
We handle required gas and electrical permits and coordinate any inspections with the local authority. If a gas line relocation or panel work is involved, we include that scope up front so there are no surprises.
Your final documents include model and serial numbers, filter size, thermostat settings, and warranty registration details.
When a hybrid plan saves more
In most Durham winters, a cold-climate heat pump can cover the majority of heating hours efficiently, while the furnace handles deep cold and fast recovery. The thermostat manages the handoff based on outdoor temperature.
If you are replacing a furnace today, we can rough-in hybrid-ready returns and controls so the future heat pump install is simple. Read more about furnaces and heat pumps on the service pages: Furnace Install & Repair and Heat Pumps.
What to expect on installation day
We protect floors, remove the old unit, set the new furnace on a leveled pad, seal and tape connections, and verify gas, venting, and electrical. Startup includes airflow and static pressure checks, temperature rise verification, and thermostat programming.
