Three months of hard work, then a long rest
Your air conditioner in Midland only gets June through August to do its job, but summer afternoons averaging 81°F mean it works hard for that stretch. A unit that sits idle most of the year can develop problems in the off season, weak wiring, a low refrigerant charge, dirt on the coil, none of which show up until the first hot day asks the system to run.
Midland has also logged 11 hail events and 50 damaging wind events over the past ten years, with hail up to 2 inches recorded. Hail that size can bend the fins on the outdoor coil, and wind can loosen panels or knock debris into the unit. A tune-up is when a contractor checks the coil, the fins, and the cabinet for that kind of damage before it turns into a bigger repair mid-summer.

A tune-up checks the refrigerant charge, cleans the coils, tests the capacitor and tightens the electrical connections.
Michigan requires HVAC contractors to hold a state license.
Michigan's Board of Mechanical Rules issues that license, and it covers the contractor, not the individual job. So the license you're checking for belongs to the company or person doing the work, not to this particular visit.
For a maintenance call on your air conditioner, that license is what stands behind the technician in your driveway. If the work involves opening the refrigerant side of the system, checking charge or pressures, the technician also needs EPA Section 608 certification, which federal law requires everywhere in the country. The state license accounts for the contractor. The federal certification accounts for anyone handling the refrigerant itself.

- What does AC maintenance include?
- A technician checks refrigerant levels, cleans the outdoor coil, tests the capacitor, and inspects electrical connections for wear. They also check the thermostat calls for cool correctly and that the system cycles on and off the way it should. Outside, they clear leaves and debris away from the unit so it can pull in air. A clean coil and correct refrigerant charge are what let the system actually cool the house instead of just running.
- How often does an air conditioner need maintenance?
- Once a year is enough for most systems. Spring, before the cooling months start, is the best time, since Midland only asks the AC to run June through August. Getting it checked before those three months means any worn part gets caught before it fails on a hot afternoon.
- Is AC maintenance worth it?
- Yes, because most breakdowns trace back to something a technician could have caught earlier, like a weak capacitor or a coil so dirty the system struggles to cool. With summer afternoons here averaging 81°F, a system that's losing efficiency will run longer and work harder to keep up. A yearly check catches that kind of wear while it's still a small fix.
