It takes about a minute.
Three months of real heat, then it stops
Jackson County only asks for cooling from June through August. Summer afternoons average 80°F, warm enough that a new system needs to keep up, but for three months, not year round.
Any new central air conditioner installed here has to meet the federal minimum of 13.4 SEER2. That is the floor a contractor is required to install to, whether you are replacing a unit or putting one in for the first time.

Michigan requires HVAC contractors to hold a state license.
Michigan licenses HVAC contractors through the Board of Mechanical Rules. The license belongs to the contractor, not to any single job, so it covers this air conditioner installation the same way it covers every other job that contractor takes on.
For this job, that license is what stands behind the person doing the work. It is not the only check. In most cities and counties, an installation like this needs a permit from the local building office, along with an inspection once the work is done. That inspection is separate from the state license. It is the local check that the finished installation meets code.

- What size air conditioner does my house need?
- There's no set size for a house this or that big. The right size comes from a load calculation, where a contractor looks at your square footage, insulation, window count and direction, and ceiling height to find out how much heat your house actually gains on a summer afternoon. Going too big is as much a problem as too small, since an oversized unit cools the air fast but shuts off before it pulls the moisture out, leaving the house cold and clammy. A contractor can run this calculation for your specific house.
- Should I replace the whole system or just the outdoor unit?
- In most cases you want to replace the outdoor unit and the indoor coil together. The coil and the condenser are matched to work at a specific efficiency. Pairing a new condenser with an old coil usually means you lose the efficiency gain you're paying for, and it can shorten the life of the new unit. Refrigerant type is another reason, since older systems used R-22 and new equipment isn't built to use it. A contractor can look at the age and condition of what you have and tell you what makes sense to keep.
- Do HVAC contractors in Jackson 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. Asking to see it before work starts is a fair question to any contractor.
