Three months of heat, and a storm record to plan around
Brunswick summers average 81°F in June through August. That is the short window your air conditioner has to handle, and it runs hard through those three months even if it sits idle the rest of the year.
Medina County has logged 64 damaging wind events and 13 hail events over the past ten years, with hailstones as large as 2.25 inches. An outdoor unit sits outside through all of that. Any new central air conditioner installed today also has to meet the federal minimum of 13.4 SEER2, the efficiency floor for new equipment, not a measure of how it should be sized for your house.

In Ohio, HVAC licensing for homes is left to the counties.
Whether a contractor needs a license here depends on where the house sits, since Ohio leaves that decision to counties instead of setting one rule for the whole state. Ohio does define a home contractor as someone carrying at least $250,000 in liability insurance, but that is a definition written into state law, not a license the state tests for or issues.
For this job, the check that applies is the permit and inspection most local building offices require when an air conditioner is installed. That means the work gets reviewed once it's done, whether or not the county where the house sits licenses contractors.

- What size air conditioner does my house need?
- The right size comes from a load calculation, not a rule of thumb based on square footage. A contractor measures your windows, insulation, ceiling height, and how much shade your house gets before landing on a number. An oversized unit cools the air fast but shuts off before it pulls the humidity down, so the house feels damp even at the right temperature. An undersized one runs nonstop on the hot afternoons here and still falls behind.
- Should I replace the whole system or just the outdoor unit?
- If your indoor coil and outdoor unit are matched and the coil is still in good shape, replacing just the outdoor unit can work. But the two parts are built to run together, and pairing a new condenser with an old coil often means the system never hits its rated efficiency. Age matters too. If the indoor coil is old enough that it could fail soon, most contractors will tell you to do both now rather than come back for a second job. A contractor can check your coil's condition and tell you which way makes sense for your equipment.
- Do HVAC contractors in Brunswick need a state license to work on my home?
- Ohio does not license HVAC contractors at the state level for residential work, so it comes down to the county. Brunswick sits in Medina County, so check with Medina County directly on what they require before you hire anyone.
