Is a Heat Pump Right for Your London, ON Home?
6 Essential Questions to Ask Before Making Your HVAC Decision
As a London homeowner, you've probably heard the buzz about heat pumps. With Ontario's push toward cleaner energy and available rebates up to $7,100, many homeowners are wondering if it's time to make the switch from traditional furnaces and air conditioners.
But is a heat pump truly the right choice for your specific home and needs? As your local HVAC experts serving London and Southwestern Ontario for years, we've helped hundreds of homeowners make this important decision. In this comprehensive guide, we'll walk you through the 6 key questions you need to ask before investing in a heat pump.
Heat Pump vs Furnace: Understanding the Basics
Before we dive into the decision-making questions, let's clarify what makes heat pumps different from traditional heating systems.
🔥 Traditional Furnace
How it works: Burns fuel (natural gas, propane, or oil) to generate heat
Best for: Extreme cold climates, homes with existing gas lines
- Powerful heating in extreme cold
- Lower operating costs with natural gas
- Familiar technology
- Only provides heating
- Carbon emissions
- Separate AC system needed
🌡️ Heat Pump
How it works: Transfers heat between indoors and outdoors using refrigerant
Best for: Moderate climates, all-electric homes, year-round comfort
- Heating & cooling in one system
- High energy efficiency (300-400%)
- Lower carbon footprint
- Eligible for rebates up to $7,100
- Less effective in extreme cold
- Higher upfront cost
- May need backup heat source
6 Questions to Determine if a Heat Pump is Right for You
Now let's explore the key questions that will help you make an informed decision about heat pumps for your London area home.
How Well Do Heat Pumps Work in London Ontario Winters?
This is the #1 concern we hear from London homeowners. The good news: modern cold-climate heat pumps are engineered specifically for Canadian winters.
London Climate Facts: Average winter low: -10°C. Cold-climate heat pumps work efficiently down to -25°C to -30°C. Only about 5-10 days per year drop below -15°C in London.
Our Verdict: For most London winters, a properly sized cold-climate heat pump will keep your home comfortable. For those few extremely cold days, most systems include electric resistance backup heating, or you can keep your existing furnace as a backup (creating a hybrid system).
What's the Real Cost - Including Rebates and Long-Term Savings?
Upfront Costs: Ducted System: $10,000-$15,000, Ductless Mini-Split: $4,500+/zone, Hybrid System: $8,000-$12,000
Rebates (Save Up To): Canada Greener Homes Grant: $6,500, Enbridge Rebate+: $600, Total: $7,100
Our Verdict: With current rebates, the payback period for heat pumps in London is now 5-8 years for most homeowners, making it a smart financial investment.
What Type of Home Do You Have?
Ideal Candidates: Well-insulated homes built after 1990, all-electric homes using baseboards, homes with existing ductwork, open concept layouts, home additions.
Better Suited for Traditional: Poorly insulated older homes (pre-1980s), homes with extensive existing gas infrastructure.
Our Verdict: Most homes in London and Southwestern Ontario are good candidates for heat pumps, especially with the hybrid system option.
What Are Your Environmental Goals?
Environmental Impact Comparison: High-efficiency gas furnace: ~2,900 kg CO2/year. Cold-climate heat pump: ~680 kg CO2/year. That's a 75% reduction in carbon emissions!
Our Verdict: If environmental impact matters to you, heat pumps are clearly the superior choice. Even hybrid systems reduce emissions by 50-60%.
What About Maintenance and Reliability?
Heat Pump Maintenance: Bi-annual professional service, regular filter changes, outdoor unit cleaning.
Typical Lifespan: Heat Pumps: 12-15 years, Furnaces: 15-20 years, AC Units: 10-15 years.
Our Verdict: Heat pumps require slightly more maintenance than furnaces but less than maintaining separate heating and cooling systems. Maintenance plans start at $149/year.
Should You Consider a Hybrid System?
How Hybrid Systems Work: The heat pump handles heating during moderate temperatures (above -5°C to -8°C), while your existing furnace kicks in during extreme cold.
Our Verdict: Hybrid systems are an excellent option for London homeowners who want to transition to heat pump technology while maintaining the reliability of their existing furnace.
Heat Pump Scenarios for London Homes
Based on our experience serving hundreds of homeowners across London and Southwestern Ontario, here are some common scenarios and our recommendations:

Heat Pump FAQ – London Ontario
Yes, modern cold-climate heat pumps work efficiently in London's winters. They can operate effectively at temperatures as low as -25°C to -30°C, making them suitable for our climate where average winter lows are around -10°C. For the few extremely cold days (only 5-10 per year below -15°C), most systems include backup heating elements or can work with your existing furnace in a hybrid configuration. Call us for a free assessment.
Heat pump installation costs in London typically range from $7,500 to $15,000+ depending on system type, home size, and existing ductwork. Ductless mini-splits start around $4,500 per zone, while whole-home ducted systems average $10,000-$15,000. With Ontario rebates up to $7,100 (Canada Greener Homes Grant $6,500 + Enbridge $600), your out-of-pocket cost can be as low as $2,900-$7,900. We provide free personalized quotes.
Heat pumps can save money for London homeowners, especially if you're replacing electric baseboard heating (60-70% savings) or oil heating (40-50% savings). For homes with natural gas, savings depend on electricity vs gas rates. However, heat pumps provide both heating and cooling in one system, eliminating separate AC costs. Most homeowners see 20-40% reduction in overall HVAC energy costs with payback periods of 5-8 years.
Heat pumps require biannual maintenance - once in spring before cooling season and once in fall before heating season. This includes cleaning coils, checking refrigerant levels, inspecting electrical components, lubricating moving parts, and testing system performance. Regular filter changes every 1-3 months are also essential. Hawana HVAC offers maintenance plans starting at $149/year to keep your system running efficiently and extend its lifespan.
With proper maintenance, heat pumps in London Ontario typically last 12-15 years. Regular professional maintenance, proper installation, and protecting the outdoor unit from extreme weather can extend this lifespan. Most quality brands come with 10-year warranties on compressors and parts. Compare to furnaces (15-20 years) and AC units (10-15 years). Annual maintenance is key to maximizing lifespan.
A hybrid system (also called dual-fuel) combines a cold-climate heat pump with your existing gas furnace. The heat pump handles heating during moderate temperatures (above -5°C to -8°C), while your furnace kicks in during extreme cold. This gives you energy-efficient heating for 90% of London's winter plus reliable backup for the coldest days. Hybrid systems are more affordable than full heat pump installations and reduce carbon emissions by 50-60%.
Most homes in London are good candidates for heat pumps. Ideal candidates include well-insulated homes built after 1990, all-electric homes currently using baseboards, homes with existing ductwork in good condition, and home additions needing separate temperature control. Older homes with poor insulation may need upgrades first. A professional assessment can determine your home's suitability and recommend the best approach.
Ontario homeowners can access the Canada Greener Homes Grant (up to $6,500 for cold-climate heat pumps) and the Enbridge Home Efficiency Rebate+ (up to $600). Combined savings can reach $7,100. Additional municipal incentives may also be available. Hawana handles all rebate paperwork for installations we complete, ensuring you get every dollar you qualify for. Call us for a free rebate eligibility check.
Not necessarily. Modern cold-climate heat pumps can be your sole heating source in London's climate, as they work efficiently down to -25°C to -30°C. However, many homeowners choose hybrid systems (heat pump + furnace backup) for peace of mind during extreme cold or if they already have a newer furnace. For all-electric homes, heat pumps alone are usually sufficient. We can help you decide based on your specific situation.
Heat pumps significantly reduce your carbon footprint. A high-efficiency gas furnace produces about 2,900 kg of CO2 annually for an average London home, while a cold-climate heat pump produces only about 680 kg CO2 annually—a 75% reduction. Hybrid systems still reduce emissions by 50-60%. As Ontario's electricity grid continues to get cleaner (more nuclear, hydro, wind, and solar), heat pumps become even more environmentally friendly.
