Heating with a mini-split in Cleveland, OH
The short answer
In Cleveland, a median ENERGY STAR cold-climate mini-split heating a 24,000 BTU/h design load should cost about $1,172 a year: $367 more than natural gas (90% efficient), and 61% less than electric resistance. The 99% design temperature is 10°F, so capacity at 5°F rarely decides anything here.
The winter you are actually buying for
This is Cleveland's average year of hourly temperatures from 2015 through 2024 (87,630 readings at Cleveland-Hopkins International Ap, 100% of all hours). The dashed line is the 99% design temperature: only 1% of hours are colder.
What it costs, by fuel
Mini-split modeled as a median certified cold-climate unit sized to cover the load at 10°F. Seasonal efficiency in Cleveland's weather: COP 2.59. In 77 hours a year the load exceeds capacity and the estimate adds electric backup.
Three house sizes
| Design load | Heat pump | Gas | Oil | Propane | Resistance | Seasonal COP | Systems that cover it |
|---|---|---|---|---|---|---|---|
| 12,000 BTU/h | $586 | $403 | $772 | $860 | $1,517 | 2.59 | 10,966 of 14,941 |
| 24,000 BTU/h | $1,172 | $805 | $1,544 | $1,721 | $3,034 | 2.59 | 5,441 of 14,941 |
| 36,000 BTU/h | $1,759 | $1,208 | $2,316 | $2,581 | $4,551 | 2.59 | 2,740 of 14,941 |
The last column counts ENERGY STAR cold-climate systems whose published 5°F and 47°F capacities, joined by a straight line, still reach the design load at Cleveland's 10°F. How sizing works.
Not a quote. Real bills depend on insulation, thermostat habits, installation and your own Manual J. Use this to decide whether a heat pump is worth pricing, then get two local quotes.
Questions people ask
Will a mini-split work in Cleveland in winter?
Yes, if it is a cold-climate model. Cleveland's 99% design temperature from 2015–2024 hourly data is 10°F, and the lowest hour recorded was -13°F. The median ENERGY STAR cold-climate unit keeps 88% of its 47°F heating capacity at 5°F. Hours per year at or below 5°F in Cleveland: 32.
Is a heat pump cheaper than natural gas in Cleveland?
At a 24,000 BTU/h design load, we estimate $1,172 a year with a median cold-climate mini-split versus $805 for natural gas at 90% efficiency, using 18.41¢/kWh electricity and 2024 Ohio fuel prices. That is $367 more than natural gas.
How big a mini-split do I need in Cleveland?
Size to your home's heat loss at 10°F, not to square feet. For a 24,000 BTU/h load, a unit shaped like the median certified system needs about 26,750 BTU/h of 47°F capacity. 5,441 of the 14,941 certified systems cover that load at 10°F.
