How Much Does It Cost to Run a Heat Pump (Ducted or Mini-Split) in Pennsylvania? (2026)
A heat pump moves heat rather than generating it, delivering 2 to 4 units of heat for every unit of electricity. A single-zone mini-split draws under 1 kW; a whole-house ducted unit can pull 4 kW in cold weather.
A typical heat pump (ducted or mini-split) (2,000 W) costs $0.44 per hour, or about $105.60 per month at 8 hours a day in Pennsylvania. Expensive to run
| Wattage | Per hour | Per day | Per month | Per year |
|---|---|---|---|---|
| Low (800 W) | $0.18 | $1.41 | $42.24 | $513.92 |
| Typical (2,000 W) | $0.44 | $3.52 | $105.60 | $1,285 |
| High (4,000 W) | $0.88 | $7.04 | $211.20 | $2,570 |
Formula: watts ÷ 1000 × hours × price per kWh. Typical use is 8 h/day ≈ 5,840 kWh per year.
One hour of a heat pump (ducted or mini-split) (2.0 kWh) is the same electricity as
- 11km in an electric car
- 20hours of TV
- 44hours of a laptop
- 222hours of an LED bulb
In Pennsylvania, with electricity at $0.22 per kWh (source: EIA Table 5.6.A, 2026-06), a typical heat pump (ducted or mini-split) costs $0.44 per hour and about $1,285 per year at 8 hours a day. That is about 22% more than the national average for the US ($86.40 per month), because electricity in Pennsylvania costs $0.22 per kWh against $0.18 nationally. Each $1.00 of electricity buys roughly 2.3 hours of use.
How to lower the cost of running a heat pump (ducted or mini-split)
- Set it and leave it. Heat pumps are most efficient holding a steady temperature rather than being cranked up and down.
- Clean filters monthly during heavy use.
- Keep the outdoor unit clear of snow, leaves, and shrubs.
In standby it draws about 5 W, which adds roughly 44 kWh ($9.64) per year if it is never unplugged.
Frequently asked questions
Is a heat pump cheaper to run than electric resistance heating?
Yes. Even in cold climates a modern heat pump uses a third to half the electricity of baseboards or a furnace with electric strips.
How much does a heat pump cost to run per day in winter?
A 2 kW unit running 8 hours uses 16 kWh. In mild weather it cycles far less.
Does a heat pump use more electricity in cooling mode?
Usually less, because the temperature difference it works against is smaller in summer than in deep winter.
