If you're deciding between a heat pump and a gas furnace for your Coquitlam home, you're asking the right question at the right time. The answer used to be straightforward — gas furnaces were cheaper to buy, cheaper to run in BC, and performed better in cold weather. In 2026, that picture has changed significantly.
Modern cold-climate heat pumps now operate efficiently down to -15°C to -25°C — well below anything Coquitlam sees during a typical winter. BC Hydro electricity rates remain among the lowest in North America. And CleanBC rebates of up to $4,000–$5,000 for heat pump installations have materially shifted the upfront cost equation.
That said, a heat pump is not always the right answer. Older homes with undersized electrical panels, properties with poor duct layouts, or homeowners with a nearly-new gas furnace face different math than a Burke Mountain new build starting from scratch. The decision depends on your specific home, budget, and goals.
This guide lays out the full comparison — side by side, honestly — and walks through two real Coquitlam scenarios so you can see how the decision plays out in practice. We'll also cover the dual-fuel option that most homeowners don't hear about until it's too late to include in their planning.

Why Coquitlam's Climate Matters in This Decision
The heat pump vs. furnace debate looks very different in Coquitlam than it does in Prince George or Calgary. Geography and climate are decisive factors.
Mild, wet winters
According to Environment Canada climate normals for Coquitlam, the average January low is approximately -1.5°C and the average daily mean is +2.4°C. The city sees fewer than 10 days per year below -5°C. This is critically important: heat pumps reach peak efficiency in the 0°C to +10°C range — which is precisely where Coquitlam spends the bulk of its heating season. A heat pump here is doing the job it was engineered for, in the conditions it excels in.
Warm, humid summers
Coquitlam averages highs of 26–28°C in July and August, with humidity levels that make air conditioning increasingly necessary — not optional. A heat pump provides both heating and cooling in one system. A gas furnace provides heat only — meaning you'd need to add air conditioning separately if you want summer comfort, typically at an additional cost of $3,500–$5,500 for a central AC unit.
Low electricity rates
BC Hydro's Step 1 residential rate sits around $0.1039/kWh as of 2026 — one of the lowest in Canada. Because a heat pump's efficiency is measured as a multiplier of electricity (a COP of 3.5 means you get 3.5 units of heat per unit of electricity), low rates amplify that advantage. In provinces with high electricity rates, the math is more complex. In BC, it consistently favours the heat pump for operating cost.
The bottom line on climate
Coquitlam's climate is textbook heat pump territory. The winters are cold enough to need heating but mild enough that a heat pump operates at high efficiency for 95%+ of heating hours. The summers are warm enough that cooling is a real need — and a heat pump delivers it at no additional equipment cost. This is why BC Hydro's CleanBC program has aggressively incentivized heat pump adoption in Metro Vancouver specifically.

Why Heat Pumps Work Especially Well in Metro Vancouver
The case for heat pumps in Coquitlam is stronger than in most Canadian cities. Here's the technical and financial reasoning — not marketing.
Cold-climate technology has caught up with BC winters
The old objection — "heat pumps don't work when it's really cold" — applied to older systems with R-22 refrigerant and single-speed compressors. Today's cold-climate models (Mitsubishi Hyper-Heat, Daikin Fit, Bosch IDS, and Carrier Infinity) use variable-speed inverter compressors and modern refrigerants (R-410A, R-32) that maintain full rated capacity to -15°C and continue operating to -25°C at reduced capacity. Coquitlam's design temperature — the worst-case planning temperature for HVAC — is approximately -8°C. Cold-climate heat pumps exceed this threshold comfortably. We've installed over 200 heat pumps across Coquitlam since 2015, and cold-weather performance complaints are essentially nonexistent with properly selected equipment.
The efficiency advantage is enormous at Metro Vancouver temperatures
A heat pump's COP (Coefficient of Performance) isn't fixed — it rises as outdoor temperature increases. At +5°C (a typical Coquitlam heating day), a modern cold-climate heat pump runs at 3.5–4.5 COP, meaning it delivers 350–450% efficiency. At -5°C it may drop to 2.5–3.0 COP — still far better than a 96% AFUE gas furnace. Because Coquitlam spends the overwhelming majority of its heating season between 0°C and +10°C, you're capturing the heat pump's maximum efficiency advantage for most of the year.
A heat pump replaces two systems — heating and cooling
This is the single most undervalued factor in the comparison. A gas furnace heats only. If you want air conditioning — increasingly necessary in Coquitlam summers — you need a separate AC system, typically $3,500–$5,500 installed. A heat pump provides both in one system, one installation, one annual service. If you're replacing a furnace and you don't have AC, the true comparison isn't "heat pump vs. furnace" — it's "heat pump vs. furnace + air conditioner." That changes the upfront cost math substantially.
BC Hydro rates are a structural advantage
BC Hydro's electricity is 98% generated from renewable hydroelectric sources, with Step 1 residential rates around $0.1039/kWh — significantly below the national average and far below most US states. Natural gas rates in BC, meanwhile, include a carbon tax that increases annually under federal policy. The operating cost gap between heat pump and gas furnace in Coquitlam is wider than it will be in 2028, 2030, or 2032 — because gas costs will keep rising relative to electricity. Heat pump economics improve over time; gas furnace economics don't.
When a Gas Furnace Still Makes More Sense
The heat pump case is compelling in Coquitlam — but it's not universal. There are specific situations where a gas furnace remains the more practical choice, and we'll give them to you honestly.
Homes with undersized electrical panels
A ducted heat pump typically requires a 240V, 30–60A circuit on top of your home's existing load. Many Coquitlam homes built before 1990 — particularly in Maillardville, Austin Heights, and the Burquitlam corridor — have 100-amp panels that were already at capacity before the EV charger, induction range, or hot tub were added. A panel upgrade runs $2,000–$4,500 in Coquitlam, which must be factored into the total heat pump cost. For some homes, the economics tip back toward a furnace — at least until a panel upgrade is planned anyway.
Homes with a good gas furnace under 10 years old
If you have a Carrier, Lennox, or York 96% AFUE furnace that's 6–8 years old and in good working condition, replacing it with a heat pump is hard to justify on cost alone. A better approach may be adding a ductless mini-split for air conditioning and partial-load heating — essentially a hybrid system you build incrementally. When the furnace reaches end of life (typically around 18–22 years), you can evaluate a full heat pump replacement with the benefit of a future rebate structure and continued technology improvement.
Homes with inadequate or poorly designed ductwork
Ducted heat pumps require proper airflow to perform efficiently. If your home has undersized ducts, low-clearance flex duct runs, or a layout that can't distribute conditioned air effectively, a ducted system will underperform — and the fix (duct redesign and replacement) adds significant cost. In these cases, a ductless multi-zone mini-split is often the right heat pump solution, not a ducted unit. But if ductless isn't feasible for layout reasons, a high-efficiency furnace may be the pragmatic choice for heating, with mini-split heads added zone by zone for cooling.
Tight budgets where upfront cost is the binding constraint
A high-efficiency gas furnace installed in Coquitlam runs $3,500–$6,000 with no rebate requirements and no panel upgrade. If budget is the primary constraint and long-term operating cost is secondary, a furnace may simply be the accessible choice today. This is not a wrong answer — it's a practical one. The key is to choose a high-efficiency unit (96% AFUE or better) to minimize future operating cost, and to plan for heat pump integration when budget allows via the dual-fuel approach described below.
In all cases where a furnace makes sense, our furnace installation service includes a full load calculation and equipment sizing assessment — not just a straight swap to the same-size unit. An undersized or oversized furnace short-cycles and fails prematurely; proper sizing is a foundational quality check.
The Third Option: Dual-Fuel (Heat Pump + Gas Furnace)
Most homeowners frame this as a binary choice. The most cost-effective solution for many Coquitlam homes is actually a hybrid of both.
How a dual-fuel system works
A dual-fuel (or hybrid) heat pump system pairs an air-source heat pump with your existing gas furnace. The thermostat controls both systems intelligently:
Above –5°C to –10°C — Heat pump only
Covers 90–95% of Coquitlam's annual heating hours at 300–400% efficiency
Below –5°C to –10°C (the "balance point") — Gas furnace only or combined
Furnace handles the rare deep-cold periods when gas is more efficient per dollar
Summer — Heat pump in cooling mode
Full air conditioning from the same system at no additional equipment cost
The $5,000 BC rebate for dual-fuel systems
BC Hydro's CleanBC Better Homes program currently offers rebates of up to $5,000 for qualifying dual-fuel heat pump installations — slightly higher than the standard heat pump rebate because the system still retains the gas furnace backup, making it a lower barrier entry point for homeowners who are hesitant about going all-electric.
For a Coquitlam home with a functioning 5–10 year old furnace, a dual-fuel upgrade can be particularly compelling: you add the heat pump to handle the bulk of the heating load (and all cooling), keep the furnace as backup for the rare cold snap, and recover $5,000 in rebates that bring the net cost of the heat pump addition close to what a central AC-only system would cost. You end up with a significantly more efficient heating system, full air conditioning, and a maintained gas furnace backup — for a similar total cost to adding AC alone.

Two Real Coquitlam Scenarios
Abstract comparisons are useful — but seeing the decision play out in homes similar to yours is more useful. Here are two scenarios we encounter regularly.
Burke Mountain new build — heat pump is the clear choice
2,400 sq ft detached home, 200A service, no existing HVAC system
Burke Mountain in northeast Coquitlam has seen a significant wave of new construction over the past decade. These homes typically come with 200-amp electrical service, modern duct layouts, and no existing heating system — meaning the homeowner gets to choose from scratch with no sunk costs to consider.
For this scenario, the heat pump recommendation is straightforward. With 200A service, there's no panel upgrade needed. Starting from scratch means there's no existing furnace to factor in as a sunk cost. A properly sized ducted heat pump (say, a Mitsubishi Zuba-Central or Daikin Fit system) provides heating, cooling, and often dehumidification in one install. After a $4,000 CleanBC rebate, the net installed cost is roughly $7,000 – $10,000 — versus $4,500 – $6,500 for a high-efficiency furnace plus another $3,500 – $5,000 for central air conditioning.
The heat pump covers both needs at a comparable or lower total cost, with 30–50% lower annual operating costs from day one.
Heat Pump — Net Cost
$9,000 installed – $4,000 rebate = ~$5,000–$8,000 net
Heating + cooling included
Furnace + AC — Total Cost
$5,500 furnace + $4,500 AC = ~$10,000 total
No rebate. Higher annual operating cost.
1980s Maillardville rancher — more nuanced decision
1,600 sq ft rancher, 100A panel, 20-year-old Lennox furnace failing
Maillardville is one of Coquitlam's most established neighbourhoods — and many of its ranchers and bungalows were built in the 1970s and 80s with 100-amp panels, older duct layouts, and gas furnaces that are now 18–25 years old. This is the more complex scenario, and the right answer depends on several factors we assess at the home.
If the 100A panel is already near capacity, the homeowner faces a decision: plan a $2,000–$3,500 panel upgrade as part of the project, or go with a high-efficiency gas furnace replacement now and plan the panel upgrade independently for EV charging or future use. If a panel upgrade is on the horizon for other reasons (EV charger, kitchen reno), bundling it with a heat pump installation often makes financial sense.
The existing ductwork in an 80s rancher is typically serviceable but may need sealing and insulation upgrades to perform well with a heat pump. We assess this during the free quote visit — duct leakage testing is part of how we size equipment properly.
The dual-fuel approach can be ideal here: replace the failing furnace with a new 96% AFUE unit (~$4,500 installed), add a ductless mini-split heat pump in the main living area for heating and cooling (~$3,000–$4,500 after rebate), and plan a full ducted heat pump replacement when the new furnace eventually reaches end of life. This phased approach spreads the investment and provides immediate air conditioning without requiring a panel upgrade today.
Our recommendation for this scenario
Get a free assessment to test ductwork condition and measure panel capacity. If panel upgrade is feasible, a full heat pump replacement with CleanBC rebate often pencils out. If not, phased dual-fuel approach: new furnace now + mini-split + panel upgrade when budget allows.
The Honest Conclusion: It Depends — But the Bias Should Be Toward Heat Pumps in Coquitlam
Not a one-size-fits-all answer — but the direction has shifted.
Five years ago, the honest answer for most Coquitlam homeowners was: "it's close, and your specific situation determines the right call." Today, the balance has tipped toward heat pumps — driven by cold-climate technology improvements, BC Hydro rates remaining low, carbon tax increases on gas, and CleanBC rebates that have materially closed the upfront cost gap.
A heat pump is not the right answer if your panel can't support it without a costly upgrade, if you have a nearly-new high-efficiency furnace, or if your ductwork is genuinely incompatible. In those cases, a furnace replacement makes more practical sense — potentially with a phased path to heat pump integration later.
What we consistently find after 17 years of Coquitlam installations: the homeowners who make the best decision are the ones who get a proper assessment — not just a quote — before committing. An honest evaluation of your panel capacity, ductwork condition, existing equipment age, and heating load takes about 45 minutes. It costs you nothing. And it means the decision you make is based on your home's actual situation, not general advice from a blog post.
Lean toward a heat pump if:
- →Your furnace is 12+ years old or failing
- →You need air conditioning (or want it)
- →Your panel has capacity (or you're planning an upgrade)
- →You're building new or doing a major renovation
- →Long-term operating cost matters to you
- →You want to qualify for CleanBC rebates
Lean toward a furnace if:
- →Panel upgrade is cost-prohibitive right now
- →Your existing furnace is under 10 years old
- →Ductwork isn't compatible with heat pump airflow
- →Budget is the primary constraint today
- →You want a phased approach over time
- →Dual-fuel (add mini-split later) is the plan
Frequently Asked Questions
Does a heat pump work in Coquitlam winters?
Yes. Modern cold-climate heat pumps (Mitsubishi Hyper-Heat, Daikin Fit, Bosch IDS) maintain full heating capacity down to -15°C and partial capacity to -25°C. Coquitlam's average January low is around -2°C, with temperatures below -10°C rare and brief. For the vast majority of heating hours in Metro Vancouver, a properly sized cold-climate heat pump requires no backup. We've installed over 200 heat pumps in Coquitlam since 2015 — cold-weather performance is rarely an issue.
What is the dual-fuel heat pump system and is it eligible for BC rebates?
A dual-fuel (hybrid) system pairs a heat pump with an existing gas furnace. The heat pump handles all heating above roughly -10°C (which is 95%+ of Coquitlam's heating hours), and the furnace kicks in only during the coldest stretches. This combination is currently eligible for up to $5,000 through BC Hydro's CleanBC Better Homes program, depending on equipment and income. HVAC Coquitlam is a registered CleanBC contractor and manages the full rebate submission.
Is it cheaper to run a heat pump or gas furnace in BC?
In BC, heat pumps are substantially cheaper to operate. A heat pump delivers 2.5–4 units of heat for every unit of electricity used (300–400% efficiency vs. a gas furnace's 80–96%). With BC Hydro's residential rates currently around $0.12–$0.14/kWh — among the lowest in North America — and natural gas rates rising, most Coquitlam homeowners see 30–50% savings on heating costs after switching. The exact payback depends on your current equipment and usage.
Can I install a heat pump without adding ductwork?
Yes. If your home lacks ductwork or the existing ducts are undersized, a ductless mini-split heat pump (single-zone or multi-zone) is an ideal solution. It requires only a small hole through the wall for the refrigerant line. HVAC Coquitlam installs both ducted and ductless systems — we'll assess your home's layout and recommend the right configuration during a free quote visit.
How long does a heat pump last compared to a furnace?
A well-maintained heat pump in BC's mild climate typically lasts 15–20 years. Gas furnaces average 18–22 years. The gap is smaller than many homeowners expect, and heat pumps now come with 10-year parts and compressor warranties from major brands. Annual servicing — cleaning coils, checking refrigerant, testing defrost cycles — extends life significantly. HVAC Coquitlam offers annual heat pump maintenance starting at $149.
Should I get a heat pump if I already have a gas furnace that works fine?
It depends on your furnace's age and your goals. If your furnace is under 10 years old, adding a heat pump for air conditioning and shoulder-season heating (spring/fall) often makes more sense than replacing the furnace. This is essentially the dual-fuel approach. If your furnace is 12–15+ years old, a full heat pump replacement — potentially ductless if ductwork is poor — is worth evaluating. We'll run the numbers for your specific situation at no charge.
