Rexburg doesn't ask much of your air conditioner, and that's the problem
Summer afternoons here average 79°F, which is mild as far as cooling loads go. Your AC isn't running flat out for months on end, so a unit can sit idle a lot of the year and still be expected to start right up on the first warm day.
The bigger risk sits outside. Madison County has logged 60 damaging wind events and 5 hail storms over the past ten years, with hail up to 1.75 inches. Wind drives debris into the outdoor unit's coil and fan, and hail that size can bend or dent the fins that let the coil shed heat. When those fins get crushed down, the system struggles to cool even though nothing inside the house has changed.

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

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.
Idaho requires HVAC contractors to hold a state license.
The license is held by the contractor, not issued job by job, and it's on file with the HVAC Board. That means the state has tested this contractor and keeps a record of them, separate from any single repair they take on.
For a repair like this, the part that actually reaches into your air conditioner is the refrigerant line, and touching that requires its own credential on top of the state license. Any technician who opens the refrigerant side of the system must hold EPA Section 608 certification, no matter what state they work in. In Idaho, a contractor on this job is expected to carry both.

- Why is my AC not blowing cold air?
- The most common cause is low refrigerant from a leak somewhere in the line set or coil. A dirty air filter can also do it, since blocked airflow across the coil lets it ice up and stop cooling. If the outdoor unit isn't running at all while the indoor fan blows, the compressor or a capacitor may have failed. Only a technician with EPA Section 608 certification can legally check refrigerant levels, since that means opening the sealed system.
- Why is my AC leaking water?
- Most often the condensate drain line is clogged, and water is backing up instead of draining outside. It can also mean the drain pan has rusted through, or the coil has iced over and is now melting faster than the drain can handle. A dirty filter is a common cause of that icing, since it restricts the airflow the coil needs to stay above freezing. If the leak keeps happening after the line is cleared, have a contractor check the coil and pan directly.
- Why won't my AC turn on?
- Start with the thermostat. Check that it's set to cool and the temperature is below the room's current reading, and swap the batteries if the display is blank. If the thermostat looks fine, check the breaker box. A tripped breaker will shut the whole unit down. If power and settings check out and it still won't run, the issue is likely inside the unit and needs a licensed HVAC contractor to diagnose.
