Three months of real heat, then it's off again
Troy sees cooling season from June through August, with summer afternoons averaging 83°F. That is a short, hard stretch. Your air conditioner does most of its work in those three months, then sits idle the rest of the year.
Miami County has also logged 69 damaging wind events and 18 hail storms over the past ten years, with hailstones up to 1.5 inches. Whatever unit goes in needs to hold up outside through that. If you are installing new, federal rules set a minimum efficiency of 13.4 SEER2.

In Ohio, HVAC licensing for homes is left to the counties.
Ohio does not test or license HVAC contractors at the state level. Whether one exists here depends on Miami County's own rules, since the state left that decision to the counties. Ohio does define what a home contractor is, and that definition includes carrying at least $250,000 in liability insurance, but that is a description, not a test anyone passed.
For an air conditioner installation, the protection in Miami County comes from the local building office rather than a license. In most cities and counties, an installation like this needs a permit and an inspection once the work is done, and that inspection is what checks the work here rather than a state license.

- What size air conditioner does my house need?
- The right size comes from a load calculation, not a chart based on square footage. A contractor looks at your insulation, your windows, how many rooms and floors you have, and which way your house faces before landing on a number. Putting in a unit that's too big cools the air fast but shuts off before it pulls the moisture out, so the house feels clammy. Too small and it runs constantly during those June through August afternoons and never quite catches up.
- Should I replace the whole system or just the outdoor unit?
- If your indoor coil and outdoor unit are different ages or different efficiency levels, replacing just the outdoor unit usually causes problems. The two are matched at the factory to work together, and pairing a new condenser with an old coil can mean poor cooling and a shorter life for the new part. A contractor can check your coil's condition and age against the new unit and tell you whether it's worth keeping.
- Do HVAC contractors in Troy need a state license to work on my home?
- Ohio doesn't run a state license for residential HVAC work. That's handled at the county level, so whether a contractor needs a license to work on your home in Troy depends on what Miami County requires. Ask any contractor you're considering for their license or registration number and confirm it before they start.
