Geothermal Heat Pump Cost in Ontario — The Full Picture
Geothermal is the most expensive heat pump to install and the cheapest to run — the ground loop is a one-time cost that pays back over decades. It also carries the single largest HRS rebate.

The number that actually matters: net of rebate
HRS rebate: up to $12,000 for non-gas homes · $3,000 flat for gas homes
Typical net cost after the maximum rebate: $13,000 – $33,000
Ground-source systems carry the largest HRS rebate — it meaningfully changes geothermal math for non-gas homes.
Rebate requires an HRS Participating Contractor and applies until November 30, 2026 (funding window as reported; terms can change earlier).
What drives the price
Loop type
Horizontal loops (large yard, trenching) are cheaper; vertical loops (drilling) cost more but fit small lots. This is the biggest single price driver.
Ground conditions
Rock drilling costs more than soil. A site assessment settles this — do not accept a quote without one.
Home heat load
System tonnage follows your heat-loss calculation; bigger and leakier homes need bigger (pricier) systems.
Ductwork condition
Existing ducts in good shape keep costs down; duct modifications add to the bill.

Common questions
Why is geothermal so much more expensive than air-source?
The ground loop. You are paying once for a heat source that then runs at the highest efficiency of any system for 25+ years. The equipment itself is comparable to a high-end air-source unit.
Is geothermal worth it in Ontario?
For homes with high heating bills (oil, propane, electric), a large rebate, and a long ownership horizon — often yes. For gas-heated homes with cheap gas, the payback is much longer. Run both scenarios before deciding.
Does geothermal qualify for Ontario rebates?
Yes — the largest single HRS rebate, and the amount depends on your current heating fuel. The system must be installed by an HRS Participating Contractor.
