Three months of real heat, and storms in between
Flint doesn't ask a new air conditioner to run all year. Cooling season here runs June through August, with summer afternoons averaging 81°F. That's three months when the unit needs to work, and work well, then sit through the rest of the year.
The bigger test is what's around it. Genesee County saw 17 hail events and 71 damaging wind events over the past ten years, with hail up to 2.75 inches. An outdoor condenser sits outside through all of that, so the cabinet and coil fins matter as much as the cooling power inside. Any new system installed today also has to meet the federal efficiency minimum of 13.4 SEER2, the baseline for central air built since 2023.

Michigan requires HVAC contractors to hold a state license.
That license is issued and tracked by the Board of Mechanical Rules. It belongs to the contractor, not to any single job, so it stands behind every installation they do, including this one.
For this job, the license is what should be on file before anyone touches the equipment. In most cities and counties, the local building office also issues a permit for an air conditioner installation and sends someone out to inspect the finished work once it is done.

- What size air conditioner does my house need?
- It depends on your square footage, your ceiling height, how much shade your house gets, and how well it holds cooled air, so there's no single number that fits every home. A contractor works this out with a load calculation, not a tape measure and a guess. Getting this right matters more here than the sticker suggests, since a unit that's too big will cool the air fast but shut off before it pulls the humidity out of your house, leaving rooms feeling clammy even at 81 degrees. Too small, and it will run nonstop on the hottest afternoons and still fall behind. Ask whichever contractor quotes the job to show you the load calculation, not just a number they picked from experience.
- Should I replace the whole system or just the outdoor unit?
- If your indoor coil and outdoor unit weren't installed together, replacing just the outdoor unit can cause problems even when the parts seem compatible on paper. The two are matched for refrigerant charge and airflow, and pairing an old coil with a new condenser often means the system never runs at the efficiency the new unit is rated for. Age matters too. If your indoor coil is old enough that the outdoor unit is failing, the coil is usually not far behind it. A contractor can check the age and condition of your coil and tell you honestly whether it's worth pairing with new equipment or replacing at the same time.
- Do HVAC contractors in Flint 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 you can confirm it's current through the state. This matters for insurance and for any warranty on the work, since unlicensed work can void both.
