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
Pros
- Powerful heating in extreme cold
- Lower operating costs with natural gas
- Familiar technology
Cons
- 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
Pros
- Heating & cooling in one system
- High energy efficiency
- Lower carbon footprint
- Eligible for rebates
Cons
- 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
- Heat pumps maintain 100% efficiency down to about -8°C
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?
Understanding the complete financial picture is crucial. Let's break down the costs and savings.
Upfront Installation Costs
Available Rebates (Save Up To)
- Canada Greener Homes Grant: $6,500
- Enbridge Home Efficiency Rebate+: $600
- Total Potential Savings: $7,100
Long-Term Energy Savings
Most London homeowners see 20-40% reduction in overall HVAC energy costs with heat pumps, especially when replacing:
- Electric baseboard heating (60-70% savings)
- Oil heating systems (40-50% savings)
- Older AC + furnace combos (20-30% savings)
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?
Your home's characteristics significantly impact which HVAC solution works best.
Ideal Candidates for Heat Pumps:
- Well-insulated homes built after 1990
- All-electric homes currently using baseboards
- Homes with existing ductwork that's in good condition
- Open concept layouts that work well with ductless systems
- Home additions needing separate temperature control
Better Suited for Traditional Systems:
- Poorly insulated older homes (pre-1980s)
- Homes with extensive existing gas infrastructure
- Properties with limited outdoor space for the condenser unit
- Homes with complex multi-zone requirements
Our Verdict: Most homes in London and Southwestern Ontario are good candidates for heat pumps, especially with the hybrid system option. The best approach is to have a professional assessment of your specific home.
What Are Your Environmental Goals?
If reducing your carbon footprint is important to you, heat pumps offer significant advantages.
Environmental Impact Comparison
High-Efficiency Gas Furnace: ~2,900 kg CO2/year*
Cold-Climate Heat Pump: ~680 kg CO2/year*
*Based on average London home, Ontario electricity grid
That's a 75% reduction in carbon emissions! As Ontario's electricity grid continues to get cleaner (more nuclear, hydro, wind, and solar), heat pumps become even more environmentally friendly.
Our Verdict: If environmental impact matters to you, heat pumps are clearly the superior choice. Even hybrid systems that use your existing furnace as backup during extreme cold still reduce your annual emissions by 50-60%.
What About Maintenance and Reliability?
Understanding the long-term care requirements helps set proper expectations.
Heat Pump Maintenance Needs:
- Bi-annual professional service (spring and fall)
- Regular filter changes (every 1-3 months)
- Outdoor unit cleaning (keep clear of debris and snow)
- Annual coil cleaning and system inspection
Typical Lifespan in London's Climate:
- Heat Pumps: 12-15 years with proper maintenance
- High-Efficiency Furnaces: 15-20 years with proper maintenance
- Standard AC Units: 10-15 years with proper maintenance
Our Verdict: Heat pumps require slightly more maintenance than furnaces but less than maintaining separate heating and cooling systems. The key is regular professional maintenance, which we offer through our affordable maintenance plans starting at $149/year.
Should You Consider a Hybrid System?
You don't necessarily have to choose between a heat pump and furnace. A hybrid system might be your perfect solution.
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. This gives you the best of both worlds:
- Energy-efficient heating for 90% of London's winter
- Powerful backup heating for the coldest days
- Significant cost savings compared to full heat pump installation
- Reduced carbon emissions
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. They're also more affordable since you're not replacing your entire heating system.
Making Your Decision: 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:

Recommendation: CONSULTATION NEEDED - Address insulation first, then consider HVAC options
Heat Pump FAQs for London Homeowners
Answers to common questions we hear from local homeowners
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, most systems include backup heating elements.
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, your out-of-pocket cost can be significantly reduced.
Heat pumps can save money for London homeowners, especially if you're replacing electric heating. 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.
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, and testing system performance. Hawana HVAC offers maintenance plans starting at $149/year to keep your system running efficiently.
With proper maintenance, heat pumps in London Ontario typically last 12-15 years. Regular 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.
