Start with the quote—not a generic price range.
A complete installed heat-pump price can include the outdoor unit, indoor coil or air handler, furnace integration, refrigerant piping, condensate work, controls, duct transitions, electrical work, permits, commissioning and HST. A low headline price may omit work that another quote includes.
For that reason, this guide does not turn square footage into a made-up installed price. Enter the actual pre-tax quote you received and the calculator will show the Ontario HST, the conditional incentive math that can be verified today, any repayable financing you choose to model, and the remaining cash requirement.
Anonymous heat-pump budget calculator.
This is a budgeting tool, not an approval. HRS calculations use the current published per-ton schedule and caps, based on the program-rated heating capacity you enter. Better Homes Ottawa is shown separately because its loan is repayable financing and its heat-pump incentive has its own rules.
Budget estimate only. HRS and Better Homes Ottawa make the eligibility decision. The calculator shows conditional incentives in net project cost but does not assume when the incentive is paid. “Cash before incentive timing” subtracts financing only; actual cash flow depends on the program and contractor payment sequence.
What usually changes the installed price?
Two homes receiving the same outdoor model can still have different project costs. The installation scope matters more than a generic brand tier.
| Cost area | What can change it |
|---|---|
| Indoor equipment | Matched air handler, coil, furnace compatibility, electric backup heat and filtration. |
| Distribution | Duct transitions, airflow corrections, new ductless heads, line-set routing and condensate drainage. |
| Electrical | Breaker capacity, disconnect, wiring, service capacity, load management and any panel or service work. |
| Controls | Thermostat or communicating controls, dual-fuel logic, sensors and commissioning. |
| Site work | Snow stand or wall brackets, pad, access, crane or roof work, trenching and finished-space protection. |
| Permits & closeout | Electrical notification or inspection where required, commissioning records and program documentation. |
How current Ontario rebates change the net cost.
Home Renovation Savings currently calculates eligible cold-climate air-source heat-pump incentives from the system’s minimum rated heating capacity at 8.3°C (47°F). Enbridge natural-gas homes use $500 per ton up to $2,000; qualifying electricity, oil, propane and wood homes use $1,250 per ton up to $7,500. Rental systems use a separate $500-per-ton schedule up to $2,000.
Those are program formulas, not guaranteed discounts. The exact matched system must qualify, the homeowner and property must qualify, and the participating contractor must complete the required pre-installation approval. HRS also limits stacking with other Enbridge, Save on Energy and Government of Ontario incentives; funding from other sources cannot push combined support above the cost to supply and install the measure.
Rebates and financing are not the same thing.
A rebate reduces project cost if you qualify. A loan changes when you pay. Better Homes Ottawa currently offers a 20-year loan at 4.33% fixed interest, with a 4% administrative charge, a $10,000 minimum and a maximum of $125,000 or 10% of the home’s assessed value, whichever is less. The loan is tied to the property.
For eligible loan participants, Better Homes Ottawa currently publishes a $700-per-ton incentive for qualifying cold-climate air-source heat pumps. Keep that incentive separate from the loan principal when you compare options: the financing still has to be repaid.
Compare net cost only after the scope matches.
Two quotes are not comparable if one includes electrical work, controls and commissioning while the other leaves them as allowances or exclusions. Use the quote comparison tool before deciding that one contractor is cheaper.
For Ottawa-area projects, AirZone can provide an installation assessment after you have used the anonymous tools. Outside AirZone’s service area, use the same worksheet with any qualified contractor.
