Cost by nominal size
| Nominal size | Typical application | Broad installed range |
|---|---|---|
| 1.5–2 ton | Smaller / efficient homes | $7,000–$13,000 |
| 2.5–3 ton | Common mid-size applications | $9,000–$17,000 |
| 3.5–4 ton | Larger loads | $11,000–$20,000+ |
| 5 ton | High-load applications | $13,000–$24,000+ |
Nominal tonnage versus heating capacity
A “3-ton” heat pump is commonly discussed as roughly 36,000 Btu/h nominal cooling capacity, but available heating capacity changes with outdoor conditions and model design.
Do not buy tonnage from a rule of thumb
Ask the contractor what heating load they calculated, what capacity the proposed model delivers at design temperature and what backup heat strategy is assumed.
Frequently asked questions
How accurate are online heat pump cost estimates?
They are useful for budgeting but cannot account for a home’s measured heating load, duct condition, electrical service, installation access, equipment pairing and contractor pricing. Treat them as planning ranges, then compare written local quotes.
Should I choose a heat pump by square footage?
No. Square footage can help create a rough planning estimate, but equipment capacity should be selected from a recognized heating and cooling load calculation such as CSA F280.
Do rebates reduce the contractor quote upfront?
It depends on the programme. Some incentives are point-of-sale or contractor-administered, while others require applications or documentation. Confirm current programme rules before signing a contract.
