Eleven months of work for your furnace and AC
Adrian gets about one month of rest a year. From October through May the furnace carries the house, and on winter nights that average 20°F it runs long and often to hold the temperature. That kind of use wears on the igniter and the burner first, and when one of those fails the house goes cold instead of warm.
June through August, the air conditioner takes over, working against afternoons averaging 81°F. Most homes here heat with gas, so the furnace and AC are separate systems, each with its own parts that can wear out and fail on their own schedule. Lenawee County has also seen its share of winter storms and damaging wind over the years, and a system that loses power sometimes needs a check before it runs right again.

A new furnace and air conditioner would cut about $160 a year off heating and cooling for a typical Lenawee County home.
Estimates for a typical Lenawee County home, compared with an older unit built to the previous federal minimum, from EIA household energy data, Michigan fuel prices and NOAA climate normals. Your home will differ.
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.
The Board of Mechanical Rules is the state office that tests and records HVAC contractors before they can take on this kind of work. The license belongs to the contractor, not to any one job, so it stays tied to their name across every house they work in, not just yours.
For a heating and cooling repair, that license is what stands behind the work. Since Michigan licenses the contractor doing this job, that license is the thing accountable for it.

- Why is my heat not working?
- Start with the thermostat. Check that it's set to heat, the temperature is set above the room temperature, and the batteries aren't dead. If that's fine, check your breaker panel and the switch on the furnace itself, sometimes it looks like a light switch near the unit and gets bumped off. Gas furnaces will also shut down if the pilot or igniter fails, or if the flame sensor doesn't detect a flame, and that needs a contractor to look at. With winter nights here averaging 20°F, a furnace that won't start is worth calling in the same day.
- Why is my system running but not cooling the house?
- The most common cause is a dirty air filter blocking airflow over the indoor coil. Check it first, and replace it if it's gray or clogged. If the filter is clean and the system still runs without cooling, the outdoor unit's coil may be blocked with leaves or debris, or the system may be low on refrigerant, and that second problem needs a licensed contractor since it involves sealed refrigerant lines. Don't keep running the system for long stretches if it isn't cooling, it can freeze the indoor coil.
- What can I check before calling for HVAC repair?
- Check the thermostat settings and batteries first, that solves more no-heat and no-cool calls than anything else. Next check the air filter, a clogged one restricts airflow to both the furnace and the air conditioner. Check the breaker panel for a tripped breaker and any power switch near the furnace or outdoor unit. If the system runs on gas, make sure the gas valve behind it is open. If none of that explains it, a licensed contractor can diagnose the rest, and Michigan requires HVAC contractors to hold a state license through the Board of Mechanical Rules.
