Three months of hard running, all at once

Your air conditioner in Kalamazoo County gets three months to do its job, June through August, and it does it on afternoons that average 81°F. There is no easing into the season. The unit sits idle, then runs hard for a stretch and shuts down again.

That kind of start and stop is what a tune-up checks for. A technician looks at the capacitor and the contactor, the parts that take the load every time the unit kicks on, along with the refrigerant charge and the coil. Catching a weak part in spring means it fails on the bench, not on the one hot afternoon you need the house cool.

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.

The Board of Mechanical Rules issues that license, and it tests the contractor, not each job. So the license on file covers the business doing your maintenance, not this particular visit.

For an AC tune-up, the part of the work that carries its own federal rule is anything touching the refrigerant side, the coil and the lines running to it. Any technician who opens that side of the system, to check charge or recover refrigerant, has to hold EPA Section 608 certification, in Kalamazoo County or anywhere else in the country.

What does AC maintenance include?
A technician checks refrigerant pressure, cleans the outdoor coil, and tests the capacitor and contactor that get the compressor running. They will also check the filter, look at the condensate drain for clogs, and test the thermostat's cooling call. Here in Kalamazoo, cooling season only runs June through August, so this visit is best done in spring, before those 81°F afternoons start asking more of the system.
How often does an air conditioner need maintenance?
Once a year, done in spring before the cooling season starts. In Kalamazoo that means getting it done before June, since the heat here really only runs June through August and the system should be checked out before those 81°F afternoons arrive.
Is AC maintenance worth it?
Yes. A dirty coil or a weak capacitor makes the compressor work harder, and that is what leads to a system quitting on a hot afternoon instead of cooling the house. Catching a worn part in spring, before the three months of real heat, means it gets replaced on a schedule instead of during a breakdown. A contractor can price the visit for your system.
