Three months of heat, a year of weather
Your air conditioner in Warren works June through August, with summer afternoons averaging 81°F. That is the short window it has to do its job, and it leans on parts like the capacitor and contactor to start up reliably each time.
The rest of the year, the outdoor unit still sits outside taking whatever comes. Macomb County has seen 99 damaging wind events and 26 hail events over the past ten years, with hailstones as large as 1.75 inches. Wind can bend the fins on the coil or drive debris into the cabinet. Hail that size can dent the housing or damage the coil underneath it. You notice it in June, when the airflow is weaker than it should be or the house is not cooling the way it used to.

A new air conditioner would save little on running costs in Macomb County, so the repair decision comes down to the unit's condition.
Estimates for a typical Macomb 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 a part like a capacitor or contactor has failed.
Replacement makes sense when the compressor has failed or the system uses R-22 refrigerant, which is no longer made.
Michigan requires HVAC contractors to hold a state license.
The Board of Mechanical Rules issues that license. It covers the contractor, not each individual job, so the same license applies whether the work is a repair or a full installation.
This job means opening the refrigerant side of the air conditioner to check the charge or fix a leak. Federal law requires EPA Section 608 certification for that part of the work, in every state, and Michigan's license does not stand in for it. A repair like this rests on both. The state license belongs to the contractor. The federal certification belongs to whoever actually handles the refrigerant.

- Why is my AC not blowing cold air?
- Most of the time the filter is clogged and starving the system of airflow, or the refrigerant charge is low from a leak somewhere in the line set. A dirty filter makes the evaporator coil freeze over, and once that happens the air coming out turns warm even though the system is running. Low refrigerant will not top itself off. It leaked out somewhere, and a contractor needs to find that spot and seal it before adding more. If your air only feels weak and lukewarm rather than fully warm, check the filter first since that is the one thing you can look at yourself.
- Why is my AC leaking water?
- Water on the floor near your indoor unit usually means the condensate drain line is clogged. As your AC pulls moisture out of the air, that water is supposed to run out through the drain, and algae or debris builds up inside that line over time and blocks it. When that happens, the water backs up and spills out of the pan instead. A frozen evaporator coil that then thaws can cause the same thing, so if your air was also blowing weak or warm before you noticed the water, that is likely the starting point.
- Why won't my AC turn on?
- Start with the thermostat and the breaker before assuming the worst. Check that the thermostat is set to cool and a few degrees below the room temperature, and that its batteries aren't dead if it uses them. Next check the breaker panel, since a tripped breaker will keep the outdoor unit from getting power at all. If both of those look fine, the capacitor that starts the compressor may have failed, which is common after a summer of heavy use and is something a contractor can test and replace.
