Eight months of heat, most of it from gas
Cleveland asks a furnace to run October through May. That is eight months of the year, with winter nights averaging 23°F. A furnace here spends most of its life working, not sitting idle.
Most homes in the area heat with gas, and any new gas furnace has to meet a federal minimum of 80.0 percent AFUE. Storms are part of the picture too. The region has logged 17 winter storms and 221 damaging wind events over the past ten years, and in 2024, 18 percent of Ohio households lost power for 24 hours or more. A furnace installed here needs to hold up to a long season and the chance the power goes out in the middle of it.

A high-efficiency gas furnace would save about $150 a year to run in Cuyahoga County compared with a gas furnace.

In Ohio, HVAC licensing for homes is left to the counties.
In Cuyahoga County, whether your installer needs a license is a question for the county and the city, not the state. Ohio's own definition of a home contractor requires at least $250,000 in liability insurance, but that is a definition of the term, not a credential anyone had to earn.
What stands behind this job, in most cities and counties, is the permit process. A furnace installation like this needs a permit from the local building office, and the completed work gets inspected before it is signed off. That inspection is what catches a bad gas connection, which is the dangerous part of this job. Most homes in Cuyahoga County heat with gas, so that check is not a formality here.

- What size furnace does my house need?
- There's no fixed number. It comes from a load calculation, not the square footage of your house alone. A contractor measures your insulation, your windows, your ceiling height, and how much heat your attic and walls are losing, then sizes the furnace to that specific house. Too big and it short cycles, heating fast then shutting off before the house evens out. Too small and it runs constantly without catching up. With winter lows here averaging 23°F, getting the size right matters more than it would somewhere milder.
- How do I know it's time to replace my furnace?
- Age is one sign, but how it's running matters more than the number of years on it. Watch for uneven heat between rooms, a burner flame that looks yellow instead of blue, or a furnace cycling on and off more than it used to. If a contractor has already repaired it more than once in a year, or the repair bill is climbing close to what a new furnace would run, replacing it stops the cycle. Homes here need heat from October through May, eight months of the year, so a furnace that's struggling has a lot of months left to fail in.
- Is a high-efficiency furnace worth it?
- It depends on how long you plan to stay in the house and what you're paying to heat it now. A high-efficiency furnace burns less gas to make the same heat than a standard one, which by law has to reach at least 80.0 percent AFUE if it was built on or after November 19, 2015. Since 80.2% of homes here heat with gas and the season runs eight months, that difference in gas use shows up on more bills here than it would in a place with a shorter winter. A contractor can price out both options against what your current furnace costs to run.
