The question we hear more than any other right now in Surrey: "Should I replace my furnace with a heat pump?" It's a great question — and the honest answer is: it depends on your home, your budget, and your priorities. This guide will help you decide.
What's the Difference Between a Heat Pump and a Furnace?
A gas furnace generates heat by burning natural gas. It's simple, well-understood technology that's been heating Canadian homes for decades. A single-purpose appliance — it only heats.
A heat pump moves heat rather than generating it. In winter, it extracts heat energy from outdoor air (even in cold weather) and transfers it indoors. In summer, it reverses the process, acting as an air conditioner. One appliance does everything — heating AND cooling.
Head-to-Head Comparison: Heat Pump vs. Furnace for Surrey
| Factor | Gas Furnace | Heat Pump |
|---|---|---|
| Upfront Cost (Surrey) | $3,500–$8,000 | $5,000–$14,000 (before rebates) |
| After Rebates | Some FortisBC rebates | $3,000–$8,000 net |
| Heating Efficiency | 80–96% AFUE | 200–400% (COP 2–4) |
| Cooling Capability | ❌ Separate AC needed | ✅ Built-in |
| Operating Cost (Surrey) | $1,200–$2,200/year | $700–$1,400/year |
| Performance at -10°C | ✅ Full output | ⚠️ Reduced (cold-climate models: fine) |
| Carbon Footprint | Higher (burns gas) | Lower (runs on electricity) |
| Lifespan | 18–25 years | 15–20 years |
| Rebates Available | Up to $1,000 (FortisBC) | Up to $6,000+ (BC Hydro + Federal) |
Heat Pumps in BC's Climate: Does It Work?
This is the most common concern Surrey homeowners have — and it's a valid one. Older heat pump technology struggled below about -5°C, making it a poor fit for colder Canadian climates. But modern cold-climate heat pumps (like Mitsubishi's Hyper Heat or Daikin's Quaternity) operate efficiently down to -25°C or colder.
Surrey's climate is actually ideal for heat pumps. Our winters are mild by Canadian standards, with temperatures rarely dropping below -10°C for extended periods. Cold-climate heat pumps handle Surrey winters easily, and you can always add a gas backup for the rare deep-freeze event.
Who Should Get a Heat Pump?
- Homeowners replacing both a furnace AND an AC unit at the same time
- Anyone wanting to reduce their gas bill and carbon footprint
- Homes with newer electrical service (200-amp recommended)
- Homeowners who want to maximise rebate money back from government programs
- Anyone planning to stay in the home 7+ years (to realize energy savings payback)
Who Should Stick With a Gas Furnace?
- Homes with older electrical service (100-amp) where upgrade cost is significant
- Homeowners planning to sell within 2–3 years (won't see full payback)
- Situations where the existing furnace is relatively new (under 10 years old)
- Properties in areas with very high electricity rates relative to gas
The Dual-Fuel Option: Best of Both Worlds
Can't decide? Consider a dual-fuel system — a heat pump paired with a gas backup furnace. The heat pump handles the bulk of your heating at maximum efficiency, while the gas furnace activates automatically during the coldest days when the heat pump is less efficient. This system gives you the best operating economics year-round.
What About the Rebates? (This Changes Everything)
Current rebate programs make heat pumps significantly more attractive financially:
- BC Hydro CleanBC Rebate: $2,000–$4,000 for qualifying heat pumps
- FortisBC Rebate (for homes switching from gas): Up to $2,000
- Federal Greener Homes Grant: Up to $5,000
- Total possible: $6,000–$9,000+ in rebates
We handle all rebate applications on your behalf — you don't need to navigate the government forms.
Our Honest Recommendation for Surrey Homeowners
If you have an aging furnace (15+ years) and no central AC, a cold-climate heat pump is almost certainly the right call in Surrey right now. The rebates are at historic highs, the technology is mature, and Surrey's mild winters make it an ideal location.
If you have a newer, efficient gas furnace (under 10 years), the financial case for switching is weaker — focus on maintenance and plan for a heat pump when that furnace reaches end-of-life.
