It takes about a minute.
Three months of real heat, and storms in between
Adrian only asks for cooling from June through August, but those afternoons average 81°F, and a new system still has to keep the house comfortable through all of it. Size it right for those three months and it will do the job without running longer than it needs to.
Lenawee County has seen 60 damaging wind events and 11 hail storms over the past ten years, with hail up to 3 inches. An outdoor unit sits exposed to that, so the install matters as much as the equipment. Any new central air conditioner also has to meet the federal minimum of 13.4 SEER2, so that efficiency comes standard with a proper installation.

Michigan requires HVAC contractors to hold a state license.
Michigan's license covers the contractor, not each job. It tells you the state has that contractor on record, not that this particular installation was checked as it happened.
That check, for this job, comes from your local building office. In most cities and counties, installing a new air conditioner needs a permit, and an inspector looks at the work when it is finished.

- What size air conditioner does my house need?
- The right size depends on your home's square footage, ceiling height, insulation, window placement, and how much shade it gets, so there is no number that applies to every house. A contractor works this out with a load calculation, not a rule of thumb based on square footage alone. Getting this wrong in either direction causes problems. Too big and the unit cools the air fast but shuts off before it pulls the humidity out, so the house feels clammy. Too small and it runs constantly on the hot afternoons here without ever catching up.
- Should I replace the whole system or just the outdoor unit?
- In most cases the outdoor unit and the indoor coil should be replaced together. They are matched to work at a specific efficiency and capacity, and pairing a new outdoor unit with an old indoor coil usually means losing the efficiency you're paying for, sometimes voiding the warranty too. The furnace or air handler itself can often stay if it's still in good shape, since that's a separate piece of the system. A contractor can look at the age and condition of what you have and tell you which parts still make sense to keep.
- Do HVAC contractors in Adrian 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, and confirm it's current if you want to check.
