Three months of real heat, and storms the rest of the year

Summer here runs June through August, and afternoons average 80°F. That is not the brutal heat some places see, but it is three straight months where your air conditioner needs to work and work correctly. A unit that is undersized or wearing out will struggle to keep up on the hotter days in that stretch.

Lapeer County also sees its share of hail and wind. Ten years of records show 12 hail events, one with a stone over two inches across, and 65 damaging wind events in that same span. An outdoor condenser sits exposed to all of it, so the cabinet and the fins around it take the brunt of a bad storm. Any new central air conditioner installed today has to meet a federal minimum of 13.4 SEER2, so whatever goes in will start from that baseline.

Michigan requires HVAC contractors to hold a state license.

The Board of Mechanical Rules issues that license, and it covers the contractor rather than any single job. That means the state tested the person or business before putting them on record, and the license stays tied to them across every job they take on, not just this one.

For an air conditioner installation, that license is what stands behind the contractor's work. On top of that, most cities and counties require a permit from the local building office for this kind of installation, with an inspection once the work is done.

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, and the layout of your ductwork. A unit that's too big cools the room fast but shuts off before it pulls the humidity out, so the air feels clammy. A unit that's too small runs constantly and never quite catches up on the hottest afternoons. A contractor works this out with a load calculation on your actual house, not a chart based on square footage alone.
Should I replace the whole system or just the outdoor unit?
It depends on the condition and age of your indoor coil. If your coil and outdoor unit were installed together and matched for capacity, replacing just the outdoor unit can throw that match off and hurt both efficiency and cooling. Older systems also use refrigerants that newer outdoor units aren't built to run on, so the two may not be compatible at all. A contractor can check your indoor coil and tell you whether it makes sense to pair it with new equipment or replace both at once.
Do HVAC contractors in Lapeer 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 on your home.
