Livingston barely needs air conditioning at all

Summer afternoons here average 73°F. That is mild enough that homes need cooling 0 months a year, which means an air conditioner here can sit unused far more than it runs.

The bigger risk to your outdoor unit is the sky, not the heat. Park County has logged 15 hail events and 120 damaging wind events over the past ten years, with hailstones up to 1.75 inches. Hail that size can bend the fins on the outdoor coil, and high wind can rock the unit on its pad or drive debris into it. A system that sits idle most of the year can take that kind of damage and not show it until the day you finally switch it on.

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

  • An older air conditioner$30 a year
  • A new one at the federal minimum, 13.4 SEER2$30 a year

Estimates for a typical Park 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 repair itself, so it is the person or company you hire who is on record with the Department of Labor and Industry, tested and tracked by the state. If the repair on your air conditioner comes to less than $2,500, Montana does not require the person doing it to hold that license at all.

An air conditioner repair almost always means opening the refrigerant side of the system, and that part is federal, not state. Anyone who touches the refrigerant lines has to hold EPA Section 608 certification no matter where the job falls on the state's threshold.

Why is my AC not blowing cold air?
Most often the filter is clogged and starving the system of airflow, or the refrigerant charge is low from a leak. A dirty filter makes the coil freeze up, and once that happens you get warm air or barely any air at all until it thaws. Low refrigerant means less heat is being pulled out of the air passing through, and that side of the system can only be opened by a technician with EPA 608 certification. Check the filter first since that part is yours to handle.
Why is my AC leaking water?
Water around your unit usually 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 run out through the drain line. When the line clogs with algae or debris, the water backs up and finds another way out, often right into your house. A frozen coil that then thaws fast can also dump more water than the pan can handle.
Why won't my AC turn on?
Start with the thermostat and the breaker before assuming the worst. A dead thermostat battery, a breaker that tripped, or a switch near the indoor unit that got bumped off will all keep the system from starting. Given how many damaging wind events this area has seen, it is also worth checking the outdoor disconnect and looking the unit over for storm damage. If power is fine at the thermostat and breaker and it still will not start, the issue is inside the system and needs a contractor to diagnose.
