How Much Does It Cost to Run Air Conditioning in Manitoba?
Hourly, monthly and yearly cooling costs at Manitoba's electricity price, by system size and SEER rating, in Canadian dollars.

Quick answer
At Winnipeg's residential electricity price of 10.53ยข/kWh before tax (April 1, 2025), a typical 3-ton central air conditioner (SEER 14) costs about C$0.27 per hour, C$65 for a month at 8 hours a day, and roughly C$190 a year over a cooling season of about 700 hours. That price is 60% below the U.S. average and ranks #9 of 10 among Canadian provinces.

Electricity prices in Manitoba
| City | Bill at 1,000 kWh | Avg. price | Each kWh from 1,000 to 2,000 |
|---|---|---|---|
| Winnipeg | C$105.33/month | 10.53ยข/kWh | 9.59ยข/kWh |
Power in Manitoba is supplied by Manitoba Hydro. Manitoba Hydro generates almost all of its power from hydro dams, which keeps rates among the lowest in North America. Winnipeg's summers are warm enough that central AC gets real use.
Air conditioning is added on top of a home's normal use, so the price of those extra kilowatt-hours matters most. In Winnipeg, each kWh between 1,000 and 2,000 a month costs 9.59ยข, less than the average, because fixed charges are already covered. At that price, a 3-ton AC's season would cost about C$173 rather than C$190.
Cost to run AC in Manitoba by system size
Central systems and ductless mini-splits are both sized in tons (1 ton = 12,000 Btu). A single-room mini-split is usually 0.75โ1 ton; a whole house, 2โ5 tons. Costs for SEER 14 at 10.53ยข/kWh:
| System size | Per hour | Per month (8 hrs/day) | Per year |
|---|---|---|---|
| 1.5 ton (18,000 Btu) | C$0.14 | C$33 | C$95 |
| 2 ton (24,000 Btu) | C$0.18 | C$43 | C$126 |
| 2.5 ton (30,000 Btu) | C$0.23 | C$54 | C$158 |
| 3 ton (36,000 Btu) | C$0.27 | C$65 | C$190 |
| 3.5 ton (42,000 Btu) | C$0.32 | C$76 | C$221 |
| 4 ton (48,000 Btu) | C$0.36 | C$87 | C$253 |
| 5 ton (60,000 Btu) | C$0.45 | C$108 | C$316 |
What a more efficient AC saves in Manitoba
Annual cost of a 3-ton system at 700 cooling hours a year. Minimum efficiency for new central air conditioners is set by Natural Resources Canada; older units are often SEER 10 or lower.
| SEER rating | Annual cost | Savings vs. SEER 10 | 15-year savings |
|---|---|---|---|
| SEER 10 | C$265 | โ | โ |
| SEER 13 | C$204 | C$61 | C$919 |
| SEER 14 | C$190 | C$76 | C$1,138 |
| SEER 16 | C$166 | C$100 | C$1,493 |
| SEER 18 | C$147 | C$118 | C$1,770 |
| SEER 20 | C$133 | C$133 | C$1,991 |
Replacing an old AC? Price a heat pump too.
With a cooling season of about 700 hours, a premium air conditioner saves only C$42 a year over a standard one, so the extra cost takes a long time to pay back (see our 16 vs 18 SEER analysis). A cold-climate heat pump cools just as well in summer and also heats in winter, when it runs many more hours, so its efficiency pays back far faster.

Frequently asked questions
How much does it cost to run AC per hour in Manitoba?
About C$0.27 for a typical 3-ton central air conditioner rated SEER 14, at Winnipeg's average residential price of 10.53ยข/kWh before tax (April 1, 2025). A 1.5-ton unit, typical for one or two rooms, costs about C$0.14 an hour.
How much does central air cost per month in Manitoba?
Running 8 hours a day for 30 days, a 3-ton SEER 14 system uses about 617 kWh, or about C$65 before tax at 10.53ยข/kWh. Over a typical cooling season of about 700 full-load hours, it comes to roughly C$190 a year.
Is a high-efficiency air conditioner worth it in Manitoba?
For cooling alone, the savings are modest. Replacing a SEER 10 unit with a SEER 16 saves about C$100 a year, and going from SEER 14 to SEER 18 saves about C$42 a year. If you're replacing the system anyway, a heat pump that also heats in winter usually saves far more than a higher-SEER air conditioner.
How we calculated this
Power draw (kW) = tons ร 12,000 Btu/h รท SEER รท 1,000. Cost = kW ร hours ร price. Price: Hydro-Quรฉbec, Comparison of Electricity Prices in Major North American Cities (rates in effect April 1, 2025), the monthly bill for 1,000 kWh in Winnipeg divided by 1,000, before GST/HST and provincial taxes. U.S. dollar figures use US$0.703 per C$ (October 1, 2026). Cooling hours are our estimate for Manitoba's climate. Check your own bill: divide the total before tax by the kWh used to get your rate.
