How Much Does It Cost to Run a Air Compressor in Ontario? (2026)
A workshop compressor draws 1,000 to 2,500 watts while filling the tank, then sits idle until pressure drops. Intermittent use makes it cheap; leaks that keep it cycling are the hidden cost.
A typical air compressor (1,500 W) costs C$0.22 per hour, or about C$1.69 per month at 0.25 hours a day in Ontario. Cheap to run
| Wattage | Per hour | Per day | Per month | Per year |
|---|---|---|---|---|
| Low (1,000 W) | C$0.15 | C$0.037 | C$1.12 | C$13.69 |
| Typical (1,500 W) | C$0.22 | C$0.056 | C$1.69 | C$20.53 |
| High (2,500 W) | C$0.38 | C$0.094 | C$2.81 | C$34.22 |
Formula: watts ÷ 1000 × hours × price per kWh. Typical use is 0.25 h/day ≈ 137 kWh per year.
One hour of an air compressor (1.5 kWh) is the same electricity as
- 8.3km in an electric car
- 15hours of TV
- 33hours of a laptop
- 167hours of an LED bulb
In Ontario, with electricity at C$0.15 per kWh (source: Hydro-Québec 2025 comparison, 2025-04), a typical air compressor costs C$0.22 per hour and about C$20.53 per year at 0.25 hours a day. That is about 7% more than the national average for Canada (C$1.58 per month), because electricity in Ontario costs C$0.15 per kWh against C$0.14 nationally. Each C$1.00 of electricity buys roughly 4.4 hours of use.
How to lower the cost of running a air compressor
- Fix air leaks. A hissing fitting can run the compressor for hours a day.
- Drain the tank regularly so it holds its rated volume.
- Switch it off when leaving the workshop.
