Midland asks a lot of a heating and cooling system
Your furnace has to cover October through May here, eight months of the year, with winter nights averaging 18°F. That is a long stretch of cold for a system to hold up under, and it runs hard on the worst nights just to keep the house at temperature.
Summer is shorter, June through August, with afternoons averaging 81°F. Between the two seasons, a system here works 11 months out of the year. Michigan also sees its share of power go out, 34% of households last year lost it for at least a day, and Midland County has logged 15 winter storms and 50 damaging wind events over the past ten years. Whatever you install needs to hold up to both the season and what the season sometimes brings with it.

Michigan requires HVAC contractors to hold a state license.
The license is tied to the contractor, not to any one job, so it follows them from house to house rather than getting issued fresh for your installation. The Board of Mechanical Rules is the body that put it on record. It means the contractor was tested and has a state file, not that any single job gets a separate state sign-off.
What covers this particular installation is the permit. In most cities and counties in Michigan, putting in a new furnace or air conditioner needs a permit from the local building office, and the finished work gets an inspection before anyone considers it done. The license tells you the contractor was vetted. The permit and inspection are what checks the work actually in your house.

- When should I replace my HVAC system?
- Replace it when repairs start costing more than they're worth, or when the system is old enough that the next breakdown is a matter of when, not if. Most furnaces and air conditioners last 15 years or more, and past that age, parts wear out faster and efficiency drops. Winters here run cold, down to 18°F on average overnight from December through February, so a furnace that struggles in that stretch is worth replacing before it fails outright rather than after. If you're calling a repair tech more than once a year, start pricing a replacement instead of another fix.
- Should I replace my furnace and air conditioner at the same time?
- If they're close in age, yes, it usually makes sense to do both together. Furnaces and air conditioners installed at the same time tend to wear out around the same time, and pairing a new unit with an old one can mean the two don't run as efficiently together as a matched pair would. Homes here need heat for 8 months of the year and cooling for 3, so both systems get real use and neither one is a spare part. That said, if one system is only a few years old and working fine, a contractor can size a new furnace or air conditioner to pair with what's already there.
- What happens during an HVAC installation?
- A contractor removes the old equipment, sets the new unit in place, and connects it to the ductwork, gas or electric line, and thermostat. Before that, they size the system to the house, since a furnace or air conditioner that's too big or too small for the space won't heat or cool it evenly. Once it's connected, they test it, checking airflow, refrigerant charge on an air conditioner, and gas pressure or ignition on a furnace, then walk through the thermostat settings. Michigan requires HVAC contractors to hold a state license through the Board of Mechanical Rules, so it's worth confirming that before work starts.
