Casper asks a lot of an AC in a short season

Your air conditioner only runs hard from July through August here, but Casper doesn't go easy on it. Summer afternoons average 81°F, and the unit outside has to sit through everything the sky does the rest of the year too. Natrona County has logged 44 hail events and 269 damaging wind events over the past ten years, with hailstones up to 2.5 inches recorded.

That kind of weather bends the fins on your outdoor coil and can crack the fan blade or dent the cabinet enough to throw the fan off balance. You notice it as a system that runs but doesn't cool like it should, or one that suddenly gets loud when it starts up.

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

  • A new one at the federal minimum, 13.4 SEER2$150 a year
  • An older air conditioner$170 a year

Estimates for a typical Natrona County home, compared with an older unit built to the previous federal minimum, from EIA household energy data, Wyoming 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.

Why is my AC not blowing cold air?
The most common reason is a dirty air filter choking off airflow across the coil. A clogged filter starves the system and can cause the coil to freeze up, which then blows warm or weak air. Low refrigerant from a leak is another common cause, and that needs a licensed contractor to find and fix. Check the filter first since that's the one thing you can rule out yourself.
Why is my AC leaking water?
Your AC makes water as it cools the air, and that water is supposed to drain outside through a condensate line. When that line clogs with dirt or algae, the water backs up and drips inside instead. A dirty filter can also cause this by freezing the coil, which then melts and overflows the drain pan. Clearing the line usually stops the leak, but a contractor should check for a cracked pan or a coil that's icing up.
Why won't my AC turn on?
Start with the thermostat. Make sure it's set to cool and the temperature is actually below the room temperature, and check the batteries if it has a screen that looks dim or blank. If the thermostat looks fine, check the breaker box, since a tripped breaker will keep the whole system from starting. If power is getting to the unit and it still won't run, the capacitor or the compressor itself may have failed, and that's a job for a licensed contractor.
