One month of real heat, and hail that comes through hard

Red Lodge only asks its air conditioners to work in July, when afternoons average 76°F. That is not the kind of heat that runs a system into the ground the way a longer, hotter season would. When something fails here, it is more likely to be a storm than the sun.

Carbon County has logged 34 hail events over the past ten years, with stones up to 1.75 inches across. That is large enough to dent or crack the thin aluminum fins on a condenser coil, and bend the fan blade above it. Add 47 damaging wind events over the same stretch, strong enough to rock the outdoor unit on its pad or throw branches and grit into the coil, and you have a system that takes its hits from the weather, not from long months of running. If your air conditioner is blowing warm air or the outdoor fan sounds like it is straining, a bent fin or a knocked fan blade is worth ruling out before anything else.

A new air conditioner would save little on running costs in Carbon County, so the repair decision comes down to the unit's condition.

  • A new one at the federal minimum, 13.4 SEER2$100 a year
  • An older air conditioner$110 a year

Estimates for a typical Carbon 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.

The license is issued to the contractor, not to the job, so it does not expire once this repair is done. It covers the person or business doing the work, and Montana's Department of Labor and Industry keeps that record. Work under $2,500 falls outside this requirement, so a smaller repair job may not need a licensed contractor at all.

An air conditioner repair usually involves opening the refrigerant side of the system, and that work falls under a separate federal rule. Any technician handling refrigerant, in Montana or anywhere else, has to hold EPA Section 608 certification. That certification is not something the state tracks. It comes from the federal government and applies regardless of the job's cost or size.

Why is my AC not blowing cold air?
The most common cause is a dirty air filter choking off airflow, so check that first since it's the easiest to fix yourself. If the filter is clean, the coil inside could be frozen over from restricted airflow or low refrigerant, and it needs to thaw before a contractor can find the actual cause. Low refrigerant means a leak somewhere in the system, and only a technician with EPA 608 certification can legally open that side of the unit to check it. If the air coming out is warm rather than just weak, the compressor itself may have failed, and that's a repair a licensed contractor needs to diagnose.
Why is my AC leaking water?
Water around your unit almost always means the condensate drain line is clogged or the drain pan has rusted through. As the system runs, it pulls moisture out of the air, and that water is supposed to travel out through the drain line. When the line backs up with algae or debris, the water has nowhere to go but out the side of the unit, or down through your ceiling if the unit sits in an attic. A frozen coil that's thawing can also dump more water than the pan can handle, so if your AC was blowing warm air before you noticed the leak, that's likely the cause.
Why won't my AC turn on?
Start with the thermostat and the breaker, since a dead battery or a tripped breaker is the simplest explanation and the easiest to rule out. If both check out, the capacitor that gets the compressor and fan motor started may have failed, which is a common reason a unit hums or clicks but never actually starts. This area has seen its share of hail and damaging wind, so it's also worth having a contractor check the outdoor unit for storm damage. Any repair that involves opening the refrigerant lines has to be done by a technician holding EPA 608 certification, and a contractor will price the job once they see what the unit needs.
