When Ottawa's winter temperatures plunge to minus 30 and stay there for days, your heating system is not a comfort amenity — it is a survival necessity. Whether you need a new high-efficiency furnace installed in your Barrhaven home, an aging boiler serviced in your Centretown townhouse, a heat pump system added to your Kanata split-level, or emergency heating repair at 2 AM during a January cold snap, finding a qualified heating contractor in Ottawa can mean the difference between a warm, efficient home and a frozen pipe nightmare. Ottawa homeowners spend an average of $2,000 to $3,500 per ye...
Ottawa homes use a variety of heating systems. Understanding your options helps you make informed decisions when upgrading or replacing your current system.
Forced-air natural gas furnaces are the most common heating system in Ottawa, found in approximately 70 percent of residential homes. Modern high-efficiency condensing furnaces achieve 96 to 98 percent AFUE (Annual Fuel Utilization Efficiency), meaning virtually all the gas burned is converted to he...
Heat pumps are the fastest-growing heating technology in Ottawa thanks to dramatic improvements in cold-climate performance and generous government rebates. Modern cold-climate air-source heat pumps (ccASHP) can provide efficient heating down to minus 25 to minus 30 degrees Celsius, making them viab...
Hydronic boiler systems provide heat through hot water circulated to radiators, baseboard convectors, or in-floor radiant tubing. Boilers are common in older Ottawa homes, particularly in neighbourhoods like the Glebe, Old Ottawa South, Centretown, and Sandy Hill. Modern condensing boilers achieve 9...
Heating system costs depend on the type of system, the size of your home, the complexity of the installation, and whether ductwork modifications are needed.
A mid-efficiency (80 percent AFUE) gas furnace installed in Ottawa costs $3,500 to $5,000 — though these are being phased out in favour of high-efficiency models. A high-efficiency condensing gas furnace (96 to 98 percent AFUE) costs $5,000 to $8,500 installed, with premium brands like Lennox, Carri...
A cold-climate air-source heat pump (central ducted) costs $8,000 to $15,000 installed in Ottawa before rebates. A ductless mini-split heat pump system costs $4,000 to $7,000 for a single-zone and $10,000 to $20,000 for a multi-zone (3 to 4 indoor units). A ground-source geothermal system costs $25,...
An annual furnace tune-up costs $100 to $200 in Ottawa. Emergency furnace repair typically costs $200 to $600 for common issues (ignitor replacement, blower motor repair, thermocouple replacement). Major repairs like heat exchanger replacement can cost $1,500 to $3,500, at which point replacement of...
Several rebate programs make heating system upgrades more affordable for Ottawa homeowners.
The Canada Greener Homes Grant offers up to $7,100 for cold-climate air-source heat pump installation, up to $5,000 for ground-source heat pump systems, and up to $4,000 for high-efficiency furnace or boiler upgrades. The program requires a pre-retrofit and post-retrofit EnerGuide home energy evalua...
To maximize rebates, schedule the pre-retrofit energy audit before making any commitments — wait times for auditors can be 3 to 4 weeks in Ottawa. Choose equipment that is on the program's approved list (your heating contractor should confirm this). Ensure your installer is certified by the equipmen...
Heating system installation is regulated work that requires specific licenses, training, and experience.
In Ontario, gas furnace installation requires a G2 or G1 gas fitter license issued by the Technical Standards and Safety Authority (TSSA). Oil heating systems require an OBT (Oil Burner Technician) license. Heat pump installation should be performed by contractors certified by the equipment manufact...
Obtain at least three quotes from different heating contractors. Each quote should include a Manual J heat loss calculation for your home (not just a rule-of-thumb equipment sizing), the specific equipment make and model, a breakdown of labour and materials, any required ductwork modifications, elec...
Regular maintenance extends the life of your heating system, maintains efficiency, and prevents breakdowns during the coldest days of the year.
Schedule a professional furnace tune-up in September or October before the heating season begins. Replace the furnace filter (standard pleated filters every 3 months, high-efficiency filters every 6 to 12 months). Test your thermostat by setting it 5 degrees above current room temperature and verify...
Ottawa winter power outages can last hours or even days. Have a plan for heating your home if power fails — a wood-burning fireplace, a generator that can power your furnace blower, or an alternative heating source. Know the location of your furnace's emergency shutoff switch and your main gas valve...
A high-efficiency condensing gas furnace costs $5,000 to $8,500 installed in Ottawa. Premium modulating furnaces cost $7,000 to $10,000. After Canada Greener Homes Grant rebates (up to $4,000), the net cost can be significantly lower.
A quality gas furnace lasts 15 to 25 years in Ottawa with annual maintenance. Heat exchangers on high-efficiency models typically come with 10 to 20-year manufacturer warranties. Boilers can last 20 to 30 years. Heat pumps typically last 15 to 20 years.
Yes. Modern cold-climate heat pumps work effectively down to minus 25 to minus 30 degrees Celsius. They can reduce heating costs by 20 to 40 percent compared to gas furnaces and 50 to 60 percent compared to electric heating. With the $7,100 federal rebate, the payback period is typically 5 to 8 years.
Furnace sizing depends on your home's heat loss, not just square footage. A proper Manual J calculation considers insulation, windows, air tightness, and Ottawa's design temperature (minus 27 degrees Celsius). A typical Ottawa 2,000-square-foot home needs 60,000 to 100,000 BTU depending on age and insulation levels.
Annual professional maintenance is recommended, ideally in September or October before the heating season. Furnace filters should be checked monthly and replaced every 1 to 3 months depending on the type.
