Three months of heat, and hail in between
Your air conditioner in Custer County only gets three months to do its job, June through August, with afternoons averaging 84°F. That short, hard stretch means the compressor and fan motor go from sitting idle to running full days with little warm-up in between, and that kind of jump is what wears on a unit that just came out of a long rest.
Custer County has also logged 65 hail events and 94 damaging wind events over the past ten years, with hailstones as large as 2.75 inches. That kind of hail bends the thin aluminum fins on your outdoor coil, and bent fins block airflow across it. If your system is cooling less than it used to, or the outdoor unit looks dented or dinged up, that is often where it started.

A new air conditioner would save little on running costs in Custer County, so the repair decision comes down to the unit's condition.
Estimates for a typical Custer County home, compared with an older unit built to the previous federal minimum, from EIA household energy data, Montana fuel prices and NOAA climate normals. Your home will differ.
Repair makes sense when a part like a capacitor or contactor has failed.
Replacement makes sense when the compressor has failed or the system uses R-22 refrigerant, which is no longer made.
Montana requires HVAC contractors to hold a state license.
Montana licenses HVAC contractors through the Department of Labor and Industry. The license covers the contractor, not each job, so it stays with them from one house to the next. Work under $2,500 does not need a licensed contractor, so a smaller repair can legally be done by someone who is not licensed.
An air conditioner repair usually means opening the refrigerant side of the system. Any technician who does that needs EPA Section 608 certification, a federal requirement that applies in every state. That certification is separate from the Montana license and covers a different thing. It says the technician is trained to handle refrigerant without releasing it into the air. If the repair costs $2,500 or more, Montana's license requirement applies as well.

- Why is my AC not blowing cold air?
- The most common reason is a dirty air filter cutting off airflow across the coil. When the filter clogs, the coil can freeze up and blow warm air instead of cold. Low refrigerant from a leak is another common cause, and that repair can only be done by a certified contractor since it means opening the refrigerant side of the system. A thermostat set wrong or a failing capacitor can cause the same complaint, so a contractor will check all of these before deciding what's actually wrong.
- Why is my AC leaking water?
- Water around your air conditioner usually means the condensate drain line is clogged. Your AC pulls moisture out of the air as it cools, and that water is supposed to run out through the drain line to the outside. When the line clogs with algae or debris, the water backs up and drips inside instead. A frozen coil that's thawing can also leave water behind, so it's worth checking the filter first.
- Why won't my AC turn on?
- Start with the thermostat and the breaker before assuming the worst. Check that the thermostat is set to cool and below room temperature, and check the breaker panel for a tripped switch. If both look fine, the problem is likely electrical inside the unit itself, a bad capacitor or contactor being the usual suspects, and that calls for a contractor to test it.
