Three months of real work, then storms to survive the rest of the year
In Eaton County, your air conditioner only has to earn its keep from June through August. Summer afternoons average 80°F, which is not extreme heat, but it means the unit you install needs to be sized right for a short, steady season rather than a long, brutal one.
The bigger test is what sits outside the rest of the year. This area has seen 8 hail events and 11 damaging wind events over the past ten years, with hail up to 1.25 inches. That is what an outdoor condenser has to hold up against between cooling seasons. Any new central air conditioner installed here has to meet a federal minimum of 13.4 SEER2, so efficiency is already built into the equipment. What matters most on top of that is a unit and installation that can take a hailstorm without losing a season of cooling.

Michigan requires HVAC contractors to hold a state license.
That license comes from the Board of Mechanical Rules, and it covers the contractor, not the job. The state tested this contractor and keeps a record of them before they ever touch your system, but the license itself does not follow them out to your house and check the work.
That is where the permit comes in. In most cities and counties, putting in a new air conditioner needs a permit from the local building office, and the work gets inspected once it is done. The license tells you the contractor was tested. The permit and inspection are what checks this particular install, in this particular house.

- What size air conditioner does my house need?
- The right size depends on your home, not just its square footage. A contractor works this out with a load calculation that looks at your insulation, windows, ceiling height, and how much sun your walls and roof take on during the cooling months here, June through August. An oversized unit cools the air fast but shuts off before it pulls the humidity out, so the house feels clammy even at the right temperature. A contractor can walk through your home and give you the size that actually fits it.
- Should I replace the whole system or just the outdoor unit?
- In most cases you replace both the outdoor unit and the indoor coil together. The two are matched to work at a specific efficiency and capacity, and pairing a new outdoor unit with an old indoor coil usually means the system never runs the way it was designed to, and can shorten its life. If your indoor coil is still fairly new and in good shape, a contractor can tell you whether it will pair correctly with the outdoor unit you're considering. That's a judgment call best made after they've looked at what you have.
- Do HVAC contractors in Charlotte need a state license to work on my home?
- Yes. Michigan requires HVAC contractors to hold a state license, issued by the Board of Mechanical Rules. A licensed contractor has passed testing on the trade and carries the insurance the license requires, which matters if something goes wrong during the work. Ask to see the license number and confirm it's active before any work starts on your home.
