Ottawa’s climate isn’t just cold or hot—it’s intense. From -30°C winters to humid summer heatwaves exceeding 40°C with the humidex, Ottawa homes require HVAC systems that do more than the basics. Consistent comfort demands intelligent system design, high-efficiency equipment, and expert local installation.
At AirZone HVAC Services, we specialize in comprehensive Ottawa heating and cooling solutions that rise to this challenge. Whether you’re planning a furnace replacement, switching to a cold-climate heat pump, or installing a ductless mini-split, our solutions are backed by engineering expertise and guided by rebate strategy.

Mastering Ottawa Winters with Reliable Heating Solutions
Gas Furnaces: Consistent Warmth in Sub-Zero Conditions
Gas furnaces remain a staple in Ottawa due to their reliable performance and access to natural gas. Two premium models we recommend:
- Rheem R96V: Up to 96% AFUE, two-stage operation, variable-speed ECM motor, PlusOne® Direct Spark Ignition, and blocked drain sensor.
- Lennox SLP99V: Up to 99% AFUE, modulating gas valve, variable-speed blower, iComfort® smart thermostat integration.
Cold Climate Heat Pumps: Modern, Efficient & Ottawa-Proven
Contrary to outdated assumptions, today’s cold-climate air-source heat pumps (ccASHPs) operate efficiently in -25°C to -30°C. AirZone specializes in dual-fuel configurations where the heat pump handles 80%+ of your heating needs, with a gas furnace providing backup during deep freezes.
Benefits include:
- Up to 400% efficiency
- Quiet performance
- Heating and cooling in one system
- Excellent dehumidification during summer
- Reduced emissions using Ontario’s clean electricity
Electric Heating Options
For homes without gas access, modern electric furnaces and alternatives are still valid options. We work with homeowners across Metcalfe, Manotick, and Cumberland to design safe, cost-effective electric systems.

Ottawa Heating & Cooling Frequently Asked Questions
Can a heat pump really handle Ottawa winters?
Yes. Modern cold-climate heat pumps are engineered to operate efficiently in temperatures as low as -25°C to -30°C. For added peace of mind, we often recommend a dual-fuel system that combines a heat pump with a gas furnace for automatic backup during deep freezes.
How much does it cost to replace a furnace in Ottawa?
Most high-efficiency furnace replacements in Ottawa range from $3,500 to $7,500. Premium models with advanced features or installations requiring duct modifications may cost more. We provide detailed, up-front quotes to help you make an informed decision.
What HVAC rebates are available in Ottawa for 2025?
Ottawa homeowners may qualify for up to $7,500 on cold-climate heat pumps (electric-heated homes), up to $2,000 (gas-heated homes), and $12,000 on geothermal systems. A $75 rebate is also available for smart thermostats. We handle the full rebate process from start to finish.
Do I need ductwork to install air conditioning?
Not at all. Ductless mini-splits and cold-climate heat pumps offer flexible cooling and heating solutions without requiring existing ductwork. They’re ideal for older Ottawa homes, additions, or zoned comfort needs.
How often should HVAC systems be maintained?
We recommend two tune-ups per year: one in the spring for cooling systems and one in the fall for heating systems. Regular maintenance helps improve efficiency, reduce energy costs, and extend the life of your equipment.
What’s the best system for an older home without ducts?
Ductless mini-split heat pumps are ideal. They allow for zoned heating and cooling without requiring ductwork, making them perfect for heritage homes in areas like The Glebe and Sandy Hill.
What are the benefits of variable-speed HVAC systems?
Variable-speed systems improve temperature consistency, lower noise levels, provide better humidity control, and use less energy overall compared to single-speed systems.
