Why are furnace replacement quotes so different across Coquitlam contractors?

Furnace replacement quotes in Coquitlam routinely span $5,500 to $11,000, and a $3,000 to $4,000 gap between two quotes for what sounds like the same job is completely normal. The reasons are almost always legitimate, but knowing what drives them helps you compare fairly.

What Actually Separates the Numbers

Equipment accounts for the biggest share. A builder-grade 80,000 BTU single-stage furnace costs the contractor far less than a variable-speed, two-stage or modulating unit with an ECM blower motor. Both might be described as "high-efficiency," but their comfort, noise level and long-term operating costs differ considerably. Ask each contractor for the exact model number so you can compare like with like.

Sizing method matters too. A contractor who does a proper heat loss calculation (Manual J or equivalent) may quote a different capacity than one who just matches the old unit. Coquitlam's eastern location means it runs a few degrees colder than Richmond or Delta on a hard winter night, so undersizing is a real risk. A correctly sized furnace costs more upfront but avoids short-cycling, comfort complaints and premature wear.

Scope differences are the other common culprit. One quote may include removal and disposal of the old furnace, a new flue liner or PVC exhaust run, a carbon monoxide alarm upgrade, and the Technical Safety BC gas and electrical permits; another may list those as extras. In Coquitlam, both the gas permit and the electrical permit for the new circuit come from Technical Safety BC, and a contractor who pulls them properly will build that cost into the price. If a quote is suspiciously low, ask directly whether permits are included.

Venting deserves its own look. Many Coquitlam homes have an older chimney shared between the furnace and the gas water heater. When a new high-efficiency furnace switches to PVC exhaust and no longer uses the chimney, the water heater may need its own liner or a power-venter added, which can add $500 to $1,500 to the job. Not every contractor flags this upfront.

Labour rates, warranty terms and after-hours emergency coverage also vary. A contractor offering a two-year labour warranty and 24-hour service is pricing that into the quote; one offering 90 days is not.

Before you hire anyone for gas work, confirm the contractor holds a current Technical Safety BC gas contractor licence. Ask for the licence number and look it up on the Technical Safety BC website. Also ask about WorkSafeBC coverage and whether they carry liability insurance. Refrigerant work is not involved in a straight furnace swap, but the gas and permit credentials are non-negotiable.

A fair quote for a Coquitlam furnace replacement should include a heat loss calculation, the specific model and capacity, all permits, venting assessment, removal of the old unit, and a clear warranty on both parts and labour. If a quote skips any of those, ask why before you sign.

Furnace failures tend to cluster on the first cold nights of October and November, when every contractor in the Lower Mainland is suddenly busy. If your furnace is aging, getting quotes now rather than waiting for a breakdown gives you time to compare properly. With two or three Coquitlam quotes on the table, the line items will tell you which one is complete; one request through Vancouver HVAC Pro gets them started.
