Three months of real heat, then the system sits
Lansing summers run June through August, with afternoons averaging 80°F. That is the window your air conditioner has to do its job, and it needs to do it without strain on the first hot day and the last.
Ingham County has seen its share of hail and wind over the past ten years, so an outdoor condenser here needs to hold up outside, not just cool the air. Any new system installed also has to meet the federal minimum of 13.4 SEER2, the efficiency standard that applies to central air conditioners built since 2023.

Michigan requires HVAC contractors to hold a state license.
The Board of Mechanical Rules issues that license, and it covers the contractor, not the individual job. That means the license follows the company across every job it does, rather than being issued fresh for this particular installation.
For an air conditioner installation, that license is what stands behind the person doing the work. Most cities and counties in Michigan also require a permit for this kind of job, along with an inspection once it's finished, so the local building office has its own record of the work beyond what the state license covers.

- What size air conditioner does my house need?
- The right size depends on your home's square footage, how much shade and window area it has, your ceiling height, and how well it's insulated. There's no single number that works for every house, even two homes the same size can need different tonnage. A contractor will do a load calculation on your specific house rather than guess from square footage alone. Going bigger than you need isn't a safety net either, an oversized unit cools the air fast but shuts off before it pulls the humidity out of the room.
- Should I replace the whole system or just the outdoor unit?
- In most cases the outdoor unit and the indoor coil need to be matched, so replacing just one often means the other runs at a mismatched capacity. If your indoor coil is old or was paired with the failed outdoor unit, a contractor may recommend replacing both at once. Summers here only run June through August, so a mismatched system usually shows itself first on the hottest afternoons, when it struggles to keep up. A contractor can check your coil's condition and tell you whether it will work with a new outdoor unit or not.
- Do HVAC contractors in Lansing 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, it's a fair question and a licensed contractor will have no trouble giving it to you.
