Polson doesn't ask much of an air conditioner
Summer afternoons here average 76°F, and most homes don't run cooling on any real schedule through the year. That's an easy life for a condenser compared to hotter places, but it doesn't mean the unit is fine on its own.
Lake County sees real weather. Ten years of records show 57 damaging wind events and 12 hail events, one hailstone as large as 1.5 inches. Hail that size can dent a condenser's fins or bend the coil behind them, and wind carries branches and grit into the cabinet. A tune-up gets a look at the coil and fins while the damage is still cosmetic, before a bent fin turns into restricted airflow and a compressor working harder than it should.

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. Work under $2,500 does not need a licensed contractor at all. Above that line, the license is the record the state stands behind.
A maintenance visit on an air conditioner often falls under that $2,500 line, so the license may not be what applies here. What does apply, no matter the price, is federal rule. Anyone who opens the refrigerant side of your air conditioner, to check the charge or work on the coil, has to hold EPA Section 608 certification. That holds in every state and does not depend on the size of the job.

- What does AC maintenance include?
- A technician checks refrigerant charge, cleans the condenser coil, and tests the capacitor and contactor in the outdoor unit. They also check the evaporator coil, change or check the filter, and make sure the thermostat is calling for cooling correctly. Part of the visit is just running the system and watching how it responds, since a unit that starts fine but cools poorly points to a different problem than one that won't start at all.
- How often does an air conditioner need maintenance?
- Once a year is the standard for most systems, done in spring before the heat sets in. That holds even in a place like Polson, where summer afternoons average 76°F, because a coil or capacitor can wear down sitting through winter and spring just from age and weather, not just from hard use. An annual check catches that before the first hot day finds it instead.
- Is AC maintenance worth it?
- Yes, mainly because it catches the kind of failure that shows up as no cooling on the first hot day. A capacitor or contactor that's starting to go usually gives some warning during a check, like a reading that's drifted from spec, before it fails outright. Skipping maintenance doesn't damage the unit by itself, but it means small problems get found only when the system stops working.
