How much do contractors charge for furnace replacement electric in Ottawa?

Electric furnace replacement in Ottawa typically costs $3,500-$8,000 including installation, with most homeowners paying around $5,000-$6,500 for a quality mid-range system. The wide range depends on your home's size, existing ductwork condition, electrical requirements, and furnace efficiency rating.

Basic electric furnace replacement (assuming existing ductwork and adequate electrical service) runs $3,500-$5,000 for a standard efficiency unit suitable for homes up to 1,500 square feet. This includes a basic electric furnace, installation labor, permits, and connection to existing ductwork and electrical. Mid-range systems with better warranties and efficiency ratings cost $5,000-$6,500, while high-efficiency units with advanced features can reach $7,000-$8,000.

Additional costs often arise when electrical upgrades are needed. Many older Ottawa homes require electrical panel upgrades to handle modern electric furnaces, adding $1,500-$3,000 to the project. If your existing ductwork needs modification or replacement, expect another $2,000-$5,000. Homes switching from oil or gas to electric may need significant electrical work, potentially doubling the total cost.

Ottawa's climate considerations make furnace sizing critical. Electric furnaces work well in our climate but require proper sizing for efficiency. A 15kW unit typically handles 800-1,200 square feet, while larger homes need 20-25kW systems. Contractors should perform a heat load calculation considering Ottawa's winter temperatures, which regularly hit -25°C.

Installation requires permits through the City of Ottawa and ESA (Electrical Safety Authority) approval for electrical connections. TSSA certification isn't required for electric furnaces (unlike gas units), but the contractor must be licensed and pull proper permits. Installation typically takes 4-8 hours for straightforward replacements.

Professional installation is essential due to electrical requirements and ductwork connections. DIY installation isn't recommended and may void warranties. Ensure your contractor is licensed, carries WSIB coverage, and provides proper permits. Get quotes from multiple contractors and verify their credentials through the ESA contractor lookup.

Best timing for replacement is late summer or early fall before Ottawa's heating season begins. Spring installations often cost less due to lower demand, but don't wait if your current furnace is failing. Most quality electric furnaces carry 10-15 year warranties on parts with 1-2 years on labor.
