Three months of real heat, then it shuts down
Cooling season in Midland County runs June through August. Summer afternoons average 81°F, warm enough that a new system needs to size and run right from the first hot week, then sit idle most of the year.
That idle stretch matters too. Hail and wind show up in the storm record here, eleven hail events and fifty damaging wind events over the past ten years, so an outdoor unit spends its off months exposed to weather before it ever gets asked to cool anything. Any new central air conditioner installed today has to meet the federal minimum of 13.4 SEER2, so efficiency isn't something to shop around for. It's the floor.

Michigan requires HVAC contractors to hold a state license.
The Board of Mechanical Rules tests and licenses HVAC contractors in Michigan, and the license belongs to the contractor, not to any one job. Before that license is issued, the state has checked the contractor's qualifications, and the license covers the person or business doing the work, not this particular installation.
For this air conditioner installation, the license covers who is allowed to do the work. In most cities and counties, the job itself also needs a permit from the local building office, with an inspection once it's done. That inspection is what confirms the unit was installed to code, separate from anything the state license already covers.

- 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 looks at your insulation, your windows, your ceiling height, and how much shade your house gets before recommending a tonnage. 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. Undersized, and it runs nonstop on the hottest afternoons and still can't keep 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 ratings, replacing only one often causes problems. The two are matched at the factory to work together, and pairing an old coil with a new condenser can mean the system never reaches the efficiency it's rated for. Age matters too. If the indoor coil is old and worn, most contractors will tell you to do both now rather than risk it failing soon after. A contractor can check your coil's condition and tell you whether it's worth keeping.
- Do HVAC contractors in Midland 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 the license number before work starts, and confirm it if you're not sure.
