Three months of real heat, every year
Monroe County summers hit 82°F on an average afternoon, June through August. That's the stretch your air conditioner has to handle, and it needs to be sized right to keep up on the hottest days, not just the mild ones.
Any new central air conditioner installed here has to meet the federal minimum of 13.4 SEER2. Storms come through too, with hail and damaging wind on record in the area, so the outdoor unit needs to be installed where it's protected as well as sized right.

Michigan requires HVAC contractors to hold a state license.
The Board of Mechanical Rules issues that license, and it covers the contractor, not each job. That license is what stands behind whoever installs this air conditioner.
Most cities and counties also require a permit for an installation like this, along with an inspection from the local building office once the work is done. That permit and inspection are separate from the state license. They check that the finished work meets code, apart from whatever the license already covers.

- What size air conditioner does my house need?
- The right size depends on your square footage, your insulation, how many windows you have, and which way they face, so there is no single number that fits every house. A contractor works this out with a load calculation, not a tape measure alone. An oversized unit cools the air fast but shuts off before it pulls the moisture out, so the house feels damp even at the right temperature. An undersized one runs constantly through the summer trying to keep up with 82°F afternoons and never quite gets there.
- Should I replace the whole system or just the outdoor unit?
- In most cases the outdoor unit and the indoor coil need to be replaced together. They are matched to work at a specific capacity and efficiency, and pairing a new outdoor unit with an old coil usually means the system never runs at the rating either piece was built for. It can also void the manufacturer's warranty on the new equipment. The furnace or air handler itself is a separate question, and a contractor can tell you whether yours has enough life left to leave in place.
- Do HVAC contractors in Monroe 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. Ask to see it before work starts, since it's a straightforward way to confirm the person in your house is qualified to be there.
