Dillon summers don't ask much of your AC
Summer afternoons here average 71°F. Most days, your air conditioner isn't working hard to keep up with that.
What it does have to deal with is the storms. Beaverhead County saw 83 damaging wind events and 10 hail events over the last ten years, with hail up to 1.75 inches. That kind of weather can bend fins on the outdoor unit, knock debris into the coil, or loosen connections without you knowing it happened. A tune-up is the time that gets checked, before the first hot day tells you something's wrong.

Montana requires HVAC contractors to hold a state license.
The state license is tied to the contractor, not the job site, so the same license covers work anywhere in Montana. Work under $2,500 does not need a licensed contractor, which covers most maintenance visits on a single air conditioner.
A maintenance visit does not always call for a license, but if the technician opens the refrigerant side of the system to check the charge or look for a leak, federal law requires EPA Section 608 certification, no matter the size of the job or the state it happens in.

- What does AC maintenance include?
- A contractor checks refrigerant charge, cleans the condenser coil, and tests the electrical connections and capacitor. They also check the thermostat calibration and make sure the condensate drain isn't clogged. Anything that involves opening the refrigerant lines has to be done by someone with EPA 608 certification, which every qualified contractor carries.
- How often does an air conditioner need maintenance?
- Most manufacturers recommend a checkup once a year, done before the unit sees regular use. Dillon summers stay mild, with afternoons averaging 71°F, so many homes here run their AC rarely if at all. If yours sits unused most years, it still benefits from a yearly look since dust and debris settle in the coil and cabinet whether the unit runs or not.
- Is AC maintenance worth it?
- Yes, mainly because it catches small problems before they strand you on the one hot week you actually need cooling. A dirty coil or low refrigerant charge makes the compressor work harder, which shortens its life. In a place like Dillon where the unit sits idle most of the year, a checkup also confirms it will actually start and run when you finally need it.
