Missoula summers don't ask much of your AC
Summer afternoons here average 74°F, mild enough that your air conditioner spends a lot of its time barely working. That sounds easy on the machine, and in some ways it is.
But a hailstorm doesn't care how mild the season was. Missoula County has seen 21 hail events and 69 damaging wind events over the past ten years, with hail up to 2.5 inches. That kind of storm can bend the fins on your outdoor unit or knock it out of alignment even when the compressor inside is fine. A tune-up checks the cabinet and coil for that kind of damage before it turns into a bigger repair.

Montana requires HVAC contractors to hold a state license.
Montana licenses HVAC contractors through the Department of Labor and Industry. That license belongs to the contractor, not to any single job, so it carries from one service call to the next. Montana also sets an exception for small jobs. Work under $2,500 does not need a licensed contractor at all.
Whether that exception applies to your air conditioner's maintenance depends on the cost of the job. What does apply regardless of price is federal law. Anyone who opens the refrigerant side of your air conditioner has to hold EPA Section 608 certification. That rule holds in every state, and it covers the part of this job most likely to go wrong.

- What does AC maintenance include?
- A technician cleans the condenser coil, checks the refrigerant charge, and tests the capacitor and contactor in the outdoor unit. Indoors, they check the evaporator coil and the condensate drain, since a clogged drain is one of the most common reasons an AC stops cooling. They also check that the thermostat is calling for cooling correctly and look at the ductwork for obvious leaks or disconnects. Anyone opening the refrigerant side of the system has to hold EPA Section 608 certification, so that part of the job always goes to a certified technician.
- How often does an air conditioner need maintenance?
- Once a year is the standard, usually done before the unit sees regular use. Missoula summer afternoons average around 74°F, mild compared to places with longer, hotter cooling seasons, so the system here is not working as hard as it would elsewhere. Even so, a yearly check catches a weak capacitor or a low refrigerant charge before either one causes a breakdown.
- Is AC maintenance worth it?
- Yes, because most AC failures come from small problems that get worse when nobody looks at them. A weak capacitor, a dirty coil, or a low refrigerant charge all make the system work harder and cool less, and each one is easy to catch during a routine check. Missoula has recorded 21 hail events and 69 damaging wind events over the past ten years, including hail up to 2.5 inches, so an outdoor unit can take a hit even in a place with mild summers. A contractor can look at the specific system and price the job from there.
