What does a heat pump cost in Dundas after rebates?
In Dundas, as across Ontario, a ducted cold-climate heat pump costs $12,000–$19,000 installed in a typical 2,000 to 2,500 sq ft home. In a home heated by electricity, oil, propane or wood, Home Renovation Savings pays $1,250 per ton, up to $7,500, which leaves $8,250–$15,250 for a ducted system. In an Enbridge gas home it pays $500 per ton, up to $2,000, and a heat pump that keeps the furnace as backup comes to $4,500–$8,500 after the rebate.
The federal National Heat Pump Rebate adds $2,000, or up to $10,000 at or below an income limit that is $146,217 after tax for a household of four in Ontario. It covers installs from November 1, 2026 and opens in early 2027. Income-eligible homes heated by electricity or oil can get a heat pump free through the Energy Affordability Program.

Who supplies electricity and gas in Dundas?
Alectra’s licence covers the former Town of Dundas as it stood at the end of 1980, apart from 2000 Valley Inn Road. Hydro One’s licence calls that “part of the former Town of Dundas”, so in parts of Dundas, go by your bill. Dundas’s ward also takes in rural settlements such as Greensville and Rockton, where it pays to confirm gas service with Enbridge too.
Your heating fuel decides your Home Renovation Savings rate: a home heated by electricity, oil, propane or wood gets $1,250 per ton, 2.5 times the $500 per ton a gas-heated home gets.
Alectra’s programs page lists no heat pump rebate of its own. Heat pump rebates for its customers come from Home Renovation Savings, and income-eligible households can get upgrades free through Save on Energy’s Energy Affordability Program.

How cold does Dundas get, for sizing a heat pump?
The National Building Code of Canada 2020 gives Hamilton, the nearest listed location, a January design temperature of −17°C. That is the 2.5% value: the temperature falls below it for no more than about 18 hours in a typical January. The 1% value is −19°C, and the area has 3,460 heating degree-days a year. A load calculation uses the design temperature to size the heat pump and decide how much backup heat to keep.
The building code lists Hamilton, not Dundas, so installers use the City’s figure in the valley too.
What Dundas’s homes are like
At the 2021 census, postal code L9H had 12,509 occupied homes. 79% were owner-occupied and 67% were single-detached houses.
| Built | Share of homes |
|---|---|
| 1960 or earlier | 34% |
| 1961 to 1980 | 33% |
| 1981 to 2000 | 23% |
| 2001 to 2021 | 10% |
Dundas is older than the suburbs around it: 34% of homes were built in 1960 or earlier and 33% between 1961 and 1980. 79% are owner-occupied, against 66% across Hamilton. In an older house without ducts, ductless heads avoid new ductwork, which in Hamilton needs a building permit.

Does a heritage district affect a heat pump in Dundas?
It can. Melville-Park West came into force on June 27, 2026 under By-law 26-090. It covers 331 properties, generally bounded by Sydenham Street, Park Street West, Brock Street South, and Victoria and Melville streets. Cross-Melville, 57 properties, sits beside it east of Sydenham Street.
In a Heritage Conservation District, the City lists vents and A/C units among the exterior changes that need a heritage permit. It doesn’t mention heat pumps. The district’s FAQ says changes that can’t be seen from the street often need no permit, but that this depends on the district’s plan, so ask culturalheritageplanning@hamilton.ca before you choose a spot.

Where can the outdoor unit go in Dundas?
Section 6.6.10 of Dundas’s former By-law 3581-86 repeats the City’s rule: a side or rear yard, 0.6 m from the lot line, or a front yard if it is 3.0 m from the street line, 0.6 m from the side lot line and screened. A few lots have their own exception: at 12 Newcombe Road, a central air conditioning unit may sit as close as 0.4 m. The City’s interactive zoning map shows which by-law covers your lot.

Do Hamilton’s permit and noise rules apply in Dundas?
Yes. Dundas joined the City of Hamilton in 2001, so start with the Hamilton guide for permits, the noise by-law and the closed Better Homes Hamilton loan. A heritage permit, if you need one, comes on top of those.

Common questions
Is there a heat pump rebate in Dundas?
Yes, from the province: Home Renovation Savings pays $1,250 per ton of heat pump capacity, up to $7,500, in a home heated by electricity, oil, propane or wood, and $500 per ton, up to $2,000, in a home heated by Enbridge gas. The federal National Heat Pump Rebate adds $2,000, or up to $10,000 below an income limit, for installs from November 1, 2026; it opens in early 2027. We found no City of Hamilton rebate open. Every Ontario program.
Do I need a heritage permit for a heat pump in Dundas?
Possibly, if your home is in a Heritage Conservation District. The City lists A/C units among exterior changes that need a heritage permit and doesn’t mention heat pumps, so ask culturalheritageplanning@hamilton.ca before you commit.
Is a heat pump cheaper to run than gas in Dundas?
Not compared with gas. At Ontario prices from November 1, 2026, 1,000 kWh of heat costs about $31 from an Enbridge gas furnace, $48–$66 from a cold-climate heat pump, $140–$159 from electric baseboards and $277–$288 from an oil furnace. The electricity prices are the Ontario Energy Board's province-wide rates, and only the delivery charges differ between distributors, so the figures are a close guide in Dundas. A heat pump clearly lowers the bill in a home on baseboards, oil or propane. In a gas home, the case rests on replacing the air conditioner, the rebate and burning less gas, not on a smaller bill. Heat pump vs furnace works through a full year.
How do I find a heat pump installer for the rebate in Dundas?
Fill in the Home Renovation Savings heat pump form: the program emails a list of participating contractors. Hire from that list. The contractor files the application before any work starts, and an install done before approval gets no rebate. How Home Renovation Savings works.
How much does heat pump installation cost in Dundas?
Dundas pricing follows Ontario's provincial range: $12,000–$19,000 for a ducted air-source heat pump and $4,000–$8,500 for a single-zone ductless system. The Ontario row of the cost guide shows how those figures are built.
