Two months of heat, then long stretches of not running at all

Your air conditioner only earns its keep in July and August here, with afternoons around 82°F. That short, hard push is a different strain than running steady all summer. The unit sits idle most of the year, then gets asked to work through the hottest stretch without any warm-up.

Sidney's storms add to that. Ten years of records show 53 hail events and 91 damaging wind events in Richland County. Hail up to 2 inches can bend the thin aluminum fins on the outdoor coil, and wind that strong can rock the unit on its pad or throw debris into the fan. If your air conditioner is blowing warm or the outdoor fan sounds off balance, a bent coil or a fan knocked out of true is worth checking first.

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

  • A new one at the federal minimum, 13.4 SEER2$220 a year
  • An older air conditioner$230 a year

Estimates for a typical Richland 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 state tested this contractor before handing out the license, and the license belongs to them, not to any single repair. Montana keeps that record through the Department of Labor and Industry. Work under $2,500 falls outside that requirement, so a small repair bill can fall to a contractor who never had to hold the license at all.

An air conditioner repair usually means opening the refrigerant side of the system, and federal law requires EPA Section 608 certification for that, no matter which state the work happens in. If the job here runs under the $2,500 line, that federal certification is the credential actually in play, not the state license.

Why is my AC not blowing cold air?
Usually it means the system is low on refrigerant, the coil is frozen, or the compressor has failed. A dirty filter or a blocked outdoor unit can also cut off the airflow it needs to cool properly. If air is coming out but it is not cold, that points to the refrigerant circuit, and only a technician with EPA 608 certification can legally open that side of the system to check it.
Why is my AC leaking water?
Most often the condensate drain line is clogged and water is backing up instead of draining outside. A frozen evaporator coil will also cause a leak once it thaws, dripping more water than the drain pan can handle. Either way, the fix starts with finding where the water is actually coming from before anything else is touched.
Why won't my AC turn on?
Start with the thermostat and the breaker, since a dead battery or a tripped breaker will stop the system cold before anything else is wrong. If those check out, the problem is likely inside the unit, in the capacitor or the contactor that gives the compressor its start. With only 2 months of real cooling weather here, a system that sits idle the rest of the year can have a part fail quietly and not show it until the first hot day.
