A new system in Mason works eleven months of the year
Winter nights here average 25°F, and a furnace runs from October through April to keep up, seven months of the year. Summer afternoons average 84°F, with cooling needed June through September. Only one month sits outside either season, so whatever goes in has to handle both sides of the year, not just one.
53.2% of homes here heat with gas, so a new furnace is doing real work on those cold nights. Power matters too. In 2024, 18% of Ohio households went at least 24 hours without power, and the area has logged 14 winter storms and 142 damaging wind events over the past ten years. Worth asking a contractor how a new system comes back on once the power does.

In Ohio, HVAC licensing for homes is left to the counties.
Warren County sets its own rule for who can do HVAC work on houses here, since Ohio leaves that decision to counties instead of running a state license itself. That means there is no state test or state record behind a contractor's name. Ohio does define what a home contractor is expected to carry, at least $250,000 in liability insurance, but that is a definition written into the law, not a license anyone earns.
For a system installation, the protection on this job comes from the local building office rather than any license. Replacing a furnace, air conditioner or heat pump needs a permit in most cities and counties, and the finished work gets inspected before it is signed off. That inspection is what checks the gas and electrical connections, the parts of the job that are dangerous if they are wrong.

- When should I replace my HVAC system?
- Replace it when repairs start happening every year or the unit is old enough that a breakdown could leave you without heat or cooling for days. Homes here need heat from October through April and cooling from June through September, so there is only about a month of the year when either system can sit idle without you noticing right away. If your furnace or air conditioner is struggling to keep up, or a contractor has told you the same part keeps failing, replacing it before it quits saves you from being caught on a 25°F night or an 84°F afternoon with no fix available fast.
- Should I replace my furnace and air conditioner at the same time?
- If they are close in age, yes, it usually makes sense to replace them together. A furnace and air conditioner installed at different times wear differently, but when one is old enough to fail, the other is often not far behind, and replacing both at once means one installation instead of two. It is not a rule though. A contractor can look at the age and condition of each unit and tell you whether pairing the work makes sense for your house.
- What happens during an HVAC installation?
- A contractor removes the old equipment, sets the new furnace and or air conditioner in place, and connects it to your ductwork, gas line or electrical circuit, and condensate drain as needed. They check the refrigerant charge on the air conditioner, test the furnace ignition and airflow, and run the system through a full cycle before they leave. They also check that your ductwork and thermostat are matched to the new equipment, since a mismatch there can keep the new system from performing the way it should.
