What is the average cost to replace furnace and AC together

Replacing both your furnace and air conditioning together in Ottawa typically costs between $7,000 and $11,500, with most homeowners paying around $8,500 to $9,500 for quality mid to high-efficiency equipment.

Why Replace Both Together?

Bundling furnace and AC replacement makes financial sense for several reasons. You'll save on labor costs since the technician is already there working on your HVAC system, and you can often negotiate better equipment pricing when purchasing both units. Most importantly, you'll have a matched system where the indoor coil, outdoor unit, and furnace are all designed to work together efficiently.

Ottawa Market Breakdown:

For a mid-efficiency setup (80-92% furnace with standard AC), expect $7,000 to $9,000. A high-efficiency combination (96%+ furnace with variable-speed AC) typically runs $9,000 to $11,500. These prices include professional installation, permits, and basic ductwork modifications. However, if your home needs significant electrical upgrades, ductwork replacement, or gas line modifications, costs can increase by $1,500 to $3,000.

TSSA Requirements and Timing:

Both furnace and AC installation require permits in Ontario - TSSA permits for the gas furnace and electrical permits for the AC unit. Only licensed G2 or G3 technicians can legally install gas furnaces. The best time for replacement in Ottawa is during shoulder seasons (spring or fall) when HVAC contractors are less busy and you're not dependent on your existing system for comfort.

Safety and Next Steps:

If your current furnace is over 15 years old or showing signs of wear (yellow flame, rust, frequent repairs), don't wait for a breakdown during Ottawa's harsh winters. Carbon monoxide risks increase with aging furnaces, making timely replacement a safety priority. For an accurate quote based on your home's specific needs and to discuss financing options, request a free consultation from a licensed HVAC contractor who can assess your current ductwork and electrical setup.
