Heat pump cost in Ottawa: installed price, extra lines and the net after rebates

Ducted, ductless or a ground loop

Ducted. The outdoor unit feeds a coil on the furnace or an air handler. It costs least where the ducts are sound and the old air conditioner is due. Natural Resources Canada notes that heat pumps move more air than furnaces, so some duct runs need work; HomeStars puts that at $1,000–$5,000.

Ductless. Wall or floor heads on refrigerant lines, with no ducts at all. The price climbs with each head, so one room is cheap and a whole house can pass a ducted system. Details on the ductless mini-split page.

Ground source. A loop buried in the yard or drilled down. HomeStars says groundwork drives the cost; the install takes one to two weeks, against one to three days for air source.

Size in tons moves the price twice

HomeStars gives a rough starting point of 2 to 3 tons for a 1,500 sq ft home and 4 to 5 tons for 3,000 sq ft, with each extra ton adding about $500–$1,000 to equipment. Bigger or draughty houses can add $2,000–$5,000.

Size also sets the rebate. Home Renovation Savings pays per ton, worked out from the unit’s minimum heating capacity at 8.3°C. So the same tonnage figure raises the price and the cheque.

Natural Resources Canada recommends a room-by-room load calculation such as CSA F280 by a professional, and warns that an oversized unit cycles on and off in mild weather. Ask for it before you compare totals. Cold-weather output and backup sizing are on the cold-climate heat pump page.

Lines that sit beside the unit price

• Backup heat. In colder regions, HomeStars puts a dual-fuel setup or electric backup at $1,500–$4,000. Keeping the gas furnace as backup is the hybrid route.
• Electrical. An add-on unit rarely needs a new service, per Natural Resources Canada; an all-electric system normally needs 200 amps. The Ottawa guide puts a panel upgrade at $200–$2,000. ESA says almost all electrical work needs a notification of work, filed by whoever does it.
• Removal. Old furnace or air conditioner out: $500–$1,500 on the Canada guide, about $300 on the Ottawa guide, often outside the install price.
• Thermostat and labour. A smart thermostat runs $100–$300 on the Ottawa guide; HomeStars lists labour at $75–$150 an hour.
• Tax. HST in Ontario is 13%. Check whether each total includes it.

From quote to net: two worked examples

Take the retailer’s Ottawa average of $8,500 for a 2-ton ducted unit, before tax, and assume the model qualifies for both programs.

Gas-heated Enbridge home. Home Renovation Savings pays $500 a ton: $1,000. If the work runs through the Better Homes Ottawa loan, the City adds $700 a ton: $1,400. Net before tax: about $6,100.

Home heated by electric baseboards or oil. Home Renovation Savings pays $1,250 a ton: $2,500. With the City’s $1,400, the net falls to about $4,600.

The City incentive comes only through the loan, which starts at $10,000 and needs an EnerGuide assessment. The unit must be on NRCan’s cold-climate list, keep 80% or more of its capacity in the cold and run at 55 dB or less in cooling season. Both programs need approval before the install. The rebates page covers which programs combine and in what order to apply.

After the install: upkeep and service life

HomeStars puts routine servicing at $100–$300 a year; one Ottawa firm’s guide gives $150–$300. Natural Resources Canada gives air source units a 15–20 year service life and says most come with one year on parts and labour plus five to ten years on compressor parts only, varying by maker. Ask which terms apply to your model.

What the written quote should show

• Model numbers for the outdoor and indoor units, tonnage and the heating capacity at 8.3°C.
• The load calculation behind the size.
• Backup heat, duct changes, electrical work and the ESA notification as separate lines.
• Removal of old equipment, the thermostat, HST and the total.
• Who files the rebate pre-approval, and the start date after approval.

In Ontario, a renovation contract over $50 needs a written agreement. The bill can exceed an estimate in it by 10% at most unless you sign a change, and the province recommends a deposit of 10% or less. The City of Ottawa exempts heat pump installs from a building permit, except on designated heritage properties and in a Heritage District Overlay.

Who handles your request

Ottawa Heating Desk passes your request to one independent local heating and cooling company. That company calls you back, sizes the house, prices the system and the extra lines, and does the install. In the form, give the heating fuel, house size, ducts or none, and the rooms to cover.
