Three months of heat, then storms all year
Monroe County only asks for cooling three months a year, June through August, but those afternoons average 82°F and the unit has to work through all of them at once. A system that sits idle most of the year does not get the gradual break-in a furnace does. It goes from off to running hard, and that jump is when a weak capacitor or a low refrigerant charge shows itself, usually as a unit that hums but the fan does not spin, or air that is not as cold as it should be.
The outdoor unit also has to survive what the weather does to it. Monroe County has seen 95 damaging wind events and 17 hail events over the past ten years, with hail up to 2 inches. Wind drives debris into the condenser fins and bends them, which blocks airflow the unit needs to cool the refrigerant. Hail that size can dent the cabinet or damage the fan blade directly. Either one shows up the same way, an AC that runs but struggles to keep the house cool.

A new air conditioner would save little on running costs in Monroe County, so the repair decision comes down to the unit's condition.
Estimates for a typical Monroe 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 state tested this contractor before handing out that license, and the Board of Mechanical Rules keeps a record of who holds one. That license belongs to the contractor, not to any single job, so it stands behind every repair they do, not just this one.
For the actual work on your air conditioner, there's a second layer that applies no matter what state you're in. Anyone who opens the refrigerant side of your system, which a repair like this usually requires, has to hold EPA Section 608 certification. That's a federal rule, separate from Michigan's license, and it exists because refrigerant work is its own kind of risk.

- Why is my AC not blowing cold air?
- Most of the time the filter is clogged and starving the system of airflow, so check that first since it's the easiest thing to fix yourself. If the filter is clean, the problem is often low refrigerant from a leak, a failing compressor, or ice built up on the coil from restricted airflow. A dirty outdoor unit covered in grass clippings or debris can also keep the system from shedding heat properly. A contractor can tell you which one it is with a gauge check.
- Why is my AC leaking water?
- The drain line is probably clogged. Your AC pulls moisture out of the air as it cools, and that water is supposed to run out through a condensate line, but algae and dirt build up inside that line over time and block it. When it backs up, the water finds another way out, usually through the unit itself or down through your ceiling if the unit sits in an attic. A frozen coil that then thaws and dumps water fast will look similar, so a contractor needs to check whether it's the drain or the coil before doing anything.
- Why won't my AC turn on?
- Start with the thermostat. Check that it's set to cool and the temperature is below the room temperature, and if it runs on batteries, try fresh ones. If the thermostat looks fine, check your breaker panel since a tripped breaker will cut power to the whole system. Summer storms here bring damaging wind fairly often, and a power flicker during one of those can trip a breaker without you noticing. If the breaker is fine and the system still won't start, the capacitor or the contactor is a common failure point and a contractor will need to test them.
