Eleven months of work, most of it in the cold
Lapeer County gives your system almost no rest. Heat runs October through May, then the air conditioner takes over for June through August. That is eleven months a year with barely a pause between them.
Winter is the hard part. Nights average 18°F from December through February, cold enough that your furnace is cycling on and off most of the night to keep up. Each start puts strain on the igniter and the burner, and that wear is usually what ends a furnace's life. The county has also seen 17 winter storms and 65 damaging wind events over the past ten years, and storms like that bring outages. More than a third of Michigan households lost power for at least a day in 2024. Most furnaces need electricity to run the blower and controls even if they burn gas, so when the power drops, so does your heat.

Repair makes sense when one part has failed.
Replacement makes sense when the furnace's heat exchanger is cracked, the air conditioner's compressor has failed, or repairs keep coming.
Michigan requires HVAC contractors to hold a state license.
Michigan licenses HVAC contractors through the Board of Mechanical Rules. That means the state has tested the contractor and keeps a record of them. The license belongs to the contractor's business, not to any single job, so it covers this repair the same way it covers every other job they take on.
For a repair on a heating and cooling system, that license is what stands behind the work. Since Michigan's rule covers the contractor rather than each job, it is the license itself, and the board that issued it, that a homeowner in Lapeer County is relying on here.

- Why is my heat not working?
- Most times it comes down to power, gas, or airflow. Check the thermostat first and make sure it's set to heat and the batteries are good. Then check your breaker panel, because a tripped breaker will shut a furnace down completely. If the furnace has a standing pilot, look for the flame. If it uses an igniter, listen for the sound of it trying to start, a click or a hum followed by silence usually means the igniter or flame sensor needs attention from a contractor.
- Why is my system running but not cooling the house?
- The blower may be moving air, but that doesn't mean the air is cold. A dirty filter is the first thing to check, since a clogged filter chokes airflow across the coil and can cause it to freeze up. If the filter looks fine, check the outdoor unit for a coil packed with leaves or grass clippings, since it needs open airflow to release heat. If both look clear and the house still isn't cooling, the system likely needs a contractor to check refrigerant levels or look for a mechanical problem.
- What can I check before calling for HVAC repair?
- Start with the thermostat. Confirm it's set to the right mode, heat or cool, and that the temperature is actually calling for one or the other. Check the breaker panel for a tripped breaker, and check the filter, since a filter clogged with dust restricts airflow and can shut a system down. If the outdoor unit is involved, take a look and clear away any leaves, grass, or debris blocking it. If everything checks out and the system still isn't working, a licensed contractor can diagnose what's wrong.
