What to know about installing a Rheem gas furnace in a Vancouver home, including sizing, venting, and what installation day looks like.

Quick answer
Rheem is a name a lot of Vancouver homeowners already recognize from water heaters, and the company also makes a residential gas furnace lineup that CANRO installs and services. The installation process is the same regardless of brand: an accurate heat-load calculation for the specific house, sizing matched to the ductwork, correct venting for the model, gas connection with pressure testing, and a full commissioning cycle before the job is signed off.

Most homeowners know Rheem primarily as a water heater brand — it's one of the most common names on gas storage tanks and tankless units across Metro Vancouver — but the company also produces a residential furnace lineup that's sold through independent contractors like CANRO the same way the water heaters are. For a homeowner who already has a Rheem water heater and is now replacing the furnace, there's no functional advantage to matching brands between the two appliances; they operate independently and don't share components or controls. It's simply a name some homeowners are already comfortable with.
A furnace replacement often happens in a mechanical room that also houses the water heater, and in older Vancouver homes those two appliances sometimes share a common vent or sit close enough together that venting and combustion air supply for both need to be considered together, not just planned for the furnace in isolation. If the furnace is switching from natural draft to a high-efficiency sidewall-vented model, that can change the combustion air and venting picture for the water heater sharing the same space, particularly on an older shared chimney.
CANRO's assessment looks at the whole mechanical room, not just the furnace being replaced, and flags anything that needs to change about the water heater's venting as a result of the furnace swap, rather than leaving that to be discovered later.
CANRO calculates furnace sizing based on an actual heat-load assessment of the home — window area, insulation, ceiling height, and layout — rather than matching the old furnace's rated output. For homeowners who are also due for water heater maintenance or have questions about that unit, it's often practical to handle both in one visit, since the technician is already in the mechanical room and can look at both systems while there.
A residential furnace installation in Vancouver generally falls in the $4,500 to 9,500+ ballpark, depending on equipment tier, venting requirements, and whether any related work on shared mechanical room systems is needed. That's a ballpark, not a quote — CANRO confirms exact pricing after seeing the specific mechanical room in person.
Book the assessment with a bit of flexibility on timing if you can — a technician who can spend a few extra minutes reviewing the whole mechanical room rather than rushing straight to the furnace tends to catch these shared-space venting details before they become a problem on installation day rather than after.
Safety note
Connecting and commissioning a gas furnace is licensed gas fitter work under Technical Safety BC; CANRO holds gas licence LGA0043870. If you ever smell gas in your home, leave immediately and call FortisBC at 1-800-663-9911.
No — CANRO is an independent licensed contractor. We install and service Rheem furnaces along with several other major brands, without any factory-authorized claim.
No — they're separate appliances with independent controls and don't share parts or operation, so there's no functional benefit to matching brands between the two.
It can, particularly if they share a chimney or mechanical room and the furnace is switching to a different venting type. CANRO's assessment checks this specifically so nothing is missed.
Often yes — if you have questions or maintenance needs for the water heater, it's usually practical to address both while the technician is already on site for the furnace.
A standard installation is usually a one-day job; work involving venting changes for a shared mechanical room can extend that depending on scope.
Clearing stored items away from the furnace and water heater, and making sure there's a clear path to the room, helps the crew get started right away instead of spending part of the visit moving boxes.
