Hamilton’s heating season runs roughly November through April, with a shorter but real cooling season from June through September. A properly sized cold-climate heat pump typically costs Hamilton homeownersΒ $150β$260 per monthΒ to heat a mid-size home in winter andΒ $50β$90 per monthΒ to cool it in summer, on Ontario’s 2026 tiered rate.
Ontario’s residential electricity rates for 2026 sit aroundΒ 12.0Β’/kWhΒ for the first tier andΒ 14.2Β’/kWhΒ above the monthly threshold on Tiered pricing, or up toΒ 20.3Β’/kWhΒ during on-peak hours on Time-of-Use. Which plan is cheapest depends on whether your household can shift heating and cooling load to off-peak hours β many Hamilton heat pump owners on programmable or smart thermostats do best on Time-of-Use or Ultra-Low Overnight by pre-heating or pre-cooling before peak windows.
| System Size | Est. Monthly Heating Cost (NovβApr) | Est. Monthly Cooling Cost (JunβSep) |
|---|---|---|
| 1.5 β 2 ton | $95 β $170 | $30 β $55 |
| 2.5 β 3 ton | $150 β $260 | $50 β $90 |
| 3.5 β 4 ton | $210 β $340 | $70 β $115 |
| 5 ton+ | $270 β $420 | $90 β $150 |
What Drives Your Heat Pump's Running Cost
βοΈ Outdoor Temperature
Cold-climate heat pumps use more electricity per degree of heat delivered as it gets colder β Hamilton’s -10Β°C to -15Β°C stretches are the most expensive nights to heat through.
β‘ Rate Plan Choice
Time-of-Use on-peak rates (roughly 20.3Β’/kWh) are far higher than off-peak (roughly 9.8Β’/kWh) β shifting heating cycles matters as much as the equipment.
π‘οΈ Setpoint & Setbacks
Every 1Β°C of setback on a heat pump saves less than on a furnace but still adds up β avoid deep overnight setbacks, since heat pumps recover slowly on very cold days.
π Insulation & Air Sealing
Two identically sized Hamilton homes can differ 20β30% in running cost purely based on attic insulation and air sealing quality.
π§ Backup Heat Use
All-electric systems that lean on resistance backup during Hamilton cold snaps see cost spikes; hybrid dual-fuel systems shift that load to gas instead.
π Maintenance & Filters
A dirty coil or clogged filter can raise running cost 10β15% β annual maintenance keeps efficiency close to rated performance.
π‘ Ways to Lower Your Hamilton Heat Pump Bill
- Match your rate plan to your habits: If you can pre-heat overnight, Ultra-Low Overnight's 3.9Β’/kWh rate beats Tiered pricing significantly.
- Use smart/programmable setbacks β but shallow ones: A 1β2Β°C setback works better with a heat pump than a deep overnight drop.
- Book annual maintenance: Coil cleaning and refrigerant checks keep your system running near its rated HSPF2/SEER2.

FAQ About Heat Pump Operating Costs in Hamilton
How much does it cost to run a heat pump in Hamilton per month?
A typical 3-ton cold-climate heat pump heating a Hamilton home costs roughly $150 to $260 per month during the NovemberβApril heating season on Ontario’s tiered electricity rate, and $50 to $90 per month for cooling in summer.
Does a heat pump cost more to run than a gas furnace in Hamilton?
It depends on current electricity vs. natural gas pricing and system efficiency. In shoulder-season months a heat pump is typically cheaper to run than gas; during the coldest weeks, an all-electric system leaning on backup heat can cost more per month than a gas furnace.
Which Ontario electricity plan is cheapest for heat pump owners?
It depends on your usage pattern. Time-of-Use rewards shifting load to off-peak hours; Tiered pricing suits homes that can’t easily shift usage; Ultra-Low Overnight suits homes that can pre-heat or pre-cool overnight.
