Quick answer
A Tempstar gas furnace installation in Coquitlam involves matching a correctly sized unit to the home, fitting or adjusting the ductwork, venting the furnace to code, and completing a gas permit and commissioning check before the job is finished. CANRO installs Tempstar gas furnaces as part of its residential work throughout Coquitlam.

Most Tempstar installation calls CANRO gets in Coquitlam are replacements for a furnace that's failed or is nearing the end of its service life, often in an older home in Central Coquitlam, Chineside, or Cape Horn where the original heating system has been running for two decades or more. When a homeowner has had a Tempstar unit for years without major issues, replacing it with the same brand is a reasonable, low-risk choice, though we size and install the new unit independently rather than assuming the old furnace was sized correctly to begin with.
We install Tempstar the same way we install any furnace line: the outcome depends on correct sizing, ductwork, and venting far more than on the brand itself.
In an older Coquitlam home, existing ductwork was often sized for the previous furnace's airflow output, which may not match a newer, more efficient unit exactly. A technician checks trunk and branch sizing and the return air path before recommending whether the existing ducts can be reused as-is, need minor transition work, or need more significant modification.
Skipping this check is one of the more common causes of a new furnace that never quite performs the way it should: uneven room-to-room temperatures, more noise than expected, or a blower that seems to run longer than it should to satisfy the thermostat.
| Step | Why it matters |
|---|---|
| Vent sizing and route | Must match the furnace's exhaust requirements and slope correctly to drain condensation |
| Termination clearance | Kept clear of windows, doors, and fresh-air intakes per code |
| Combustion air supply | Confirmed adequate, especially in a sealed mechanical closet or crawlspace |
| Gas line pressure test | Verifies no leaks before the furnace is fired for the first time |
| Full-cycle commissioning | Ignition, flame, and airflow are checked through a complete heating cycle before sign-off |
Gas furnace installation requires a gas permit and a Technical Safety BC licensed gas fitter; CANRO holds gas licence LGA0043870. Coquitlam permits and inspections go through the city, and CANRO handles the application and inspection scheduling as part of the installation. A documented, permitted installation matters if the home is sold later, since an unpermitted furnace swap is a common flag in a pre-sale inspection.
Furnace installation and replacement in Coquitlam runs in a ballpark of $4,500 to $9,500 or more, always a ballpark rather than a quote until CANRO has seen the home. A straightforward swap that reuses ductwork and venting sits toward the lower end; work involving venting changes or significant duct rework sits higher. Most standard installations are completed within a single day.
Safety note
Furnace installation involving gas piping and venting must be carried out by a Technical Safety BC licensed gas fitter. If you smell gas at any point, leave the home immediately and call FortisBC's emergency line at 1-800-663-9911 from a safe location.
It's a reasonable choice if the old unit served well, though CANRO sizes and installs the new furnace independently rather than assuming the previous system was sized correctly.
Often it can be reused, but a technician checks trunk sizing and the return air path first to confirm it supports the new unit's airflow requirements.
It falls in a ballpark of $4,500 to $9,500 or more, depending on the scope of work. This is a ballpark, not a quote, confirmed after a home assessment.
Yes, a gas permit is required and the work must be done by a licensed gas fitter. CANRO manages the permit application and inspection.
A standard swap typically takes about a day. Work involving new venting or duct changes can take longer.
It can be, provided the sizing, ductwork, and venting are properly assessed rather than simply matching the old system.
Yes, the work area is left tidy and the old furnace is removed, so you're not left with debris or an old unit to deal with afterward.
Yes, most installations don't require you to leave the home, though the mechanical space itself will be off-limits to household traffic while work is underway.
