For houses with the land, the load and the horizon. We would rather talk you out of one than sell you a system that takes thirty years to make sense.
Three things have to be true at once, and it is the combination that is rare rather than any one of them.
The fourth factor is what you are replacing. Against electric baseboard or oil, ground source is transformative. Against a modern condensing gas furnace in a region with cheap gas, the operating saving alone will not carry it.
No federal credit applies to a house. The Clean Technology ITC is explicitly restricted to commercial and industrial property.
Ontario's Home Renovation Savings Program is open and pays up to $12,000 towards a ground source system — the largest single amount in the programme. It publishes no end date and the IESO has budgeted it into 2027. A 30 November 2026 closing date circulates in the trade; we have not found it published by the programme or the IESO, so we do not repeat it.
Eligibility runs through registered participating contractors and registration has been paused, so we confirm the position project by project rather than promising a rebate. The federal Greener Homes Affordability Program, which is the current federal residential route, is running in five provinces and has no Ontario agreement. We would rather tell you that now.
For most Ontario houses, a cold-climate air-source heat pump delivers the large majority of the benefit for roughly a third of the capital, with no drilling, no restoration, and a far shorter disruption. That is not a lesser recommendation. It is usually the correct one.
Where ground source genuinely wins — an acreage property, an oil-heated home, a large house with a long horizon, or a site where an outdoor unit is unacceptable — we will tell you that too, and show the comparison rather than assert it.
Drilling or trenching, loop and header, a plant location indoors, connection to existing or new distribution, and restoration of the ground afterwards. On a vertical field the drilling is a matter of days; restoration and landscaping usually take longer than people expect and should be in the quote, not discovered later.
Financing is available on qualifying projects.
Temporarily, yes — particularly a horizontal field, which is effectively a large excavation. Restoration is part of the work and should be itemised in the quote. A vertical field disturbs far less area.
Yes. The Home Renovation Savings Program pays up to $12,000 towards a ground source heat pump, the largest single amount in the programme, through a registered participating contractor. No end date is published for it. Registration for new contractors has been paused, so we confirm the position project by project.
Better efficiency, especially in deep cold, no outdoor unit, and a much longer life on the ground loop. Against roughly three times the capital cost. For most Ontario houses air-source is the better investment, and we will say so.
