In Mason, your system barely gets a break
Eleven months out of the year, your furnace or your air conditioner is working. Heat from October through April, cooling from June through September. That leaves one month where nothing runs hard.
Winter nights here average 25°F, so the burner is cycling on and off most of the night to hold the house steady. Summer afternoons average 84°F, and the compressor answers back the same way, kicking on again and again to keep up. All that cycling is what wears out an igniter or a capacitor before its time. You notice it as a furnace that takes a few tries to light, or an AC that runs but can't quite catch up with the heat outside.
Ohio has had its share of winter storms and damaging wind over the past ten years, and storms knock out power. In 2024, 18% of Ohio households lost power for a full day or more. Most furnaces and air conditioners come back on their own once power returns, but if a system was already struggling, an outage like that is often what pushes it the rest of the way to a breakdown.

A new furnace and air conditioner would cut about $160 a year off heating and cooling for a typical Warren County home.
Estimates for a typical Warren County home, compared with an older unit built to the previous federal minimum, from EIA household energy data, Ohio fuel prices and NOAA climate normals. Your home will differ.
Repair makes sense when one part has failed.
Replacement makes sense when the furnace's heat exchanger is cracked, the air conditioner's compressor has failed, or repairs keep coming.
In Ohio, HVAC licensing for homes is left to the counties.
Ohio has no state license for this kind of work. Licensing is left to the counties, so whether a contractor needs one depends on where the house sits rather than on any state test. What Ohio does require, in its definition of a home contractor, is at least $250,000 in liability insurance. That is not a license and nobody is tested to meet it. It is just the insurance floor a business has to clear to count as a contractor under state law.
For a repair on your heating and cooling system, that means the state itself is not the one standing behind the work here. Its part stops at that insurance definition. If your county licenses HVAC contractors, that local license is what backs the job instead.

- Why is my heat not working?
- Start with the thermostat. Check that it is set to heat and the temperature is set above the room temperature, then check the breaker or furnace switch. If the switch is on and nothing happens, the igniter or flame sensor may have failed, and that is a job for a contractor. Winter nights here average 25°F, so a furnace that is down for a day is worth treating as urgent.
- Why is my system running but not cooling the house?
- The most common cause is a dirty filter blocking airflow, so check that first. If the filter is clean, look at the outdoor unit and make sure it is not covered in leaves or debris, since that blocks the coil from releasing heat. A system that runs constantly and never cools could also be low on refrigerant, which means a leak somewhere, and that takes a contractor to find and fix.
- What can I check before calling for HVAC repair?
- Check the thermostat first, including the batteries if it has any and the mode it is set to. Then check the breaker panel for a tripped breaker and the filter for dirt or blockage. For a furnace, look for a flashing light on the unit itself, since many list a code you can read off before the contractor even arrives.
