Five months of Thomasville heat, every year

Your air conditioner works from May through September here, with summer afternoons averaging 87°F. That is five straight months of the compressor cycling on through the hottest part of the day, day after day.

That kind of steady load wears on the compressor and the capacitor that helps start it. When the capacitor weakens, the outdoor unit hums but the fan does not turn, or the system shuts off on its own on the hottest afternoons. Davidson County has also seen 129 damaging wind events and 26 hail events over the past ten years, and hail up to 2 inches can bend the fins on the outdoor coil, cutting the airflow it needs to cool the house.

A new air conditioner would cut about $40 a year off cooling for a typical Davidson County home.

  • A new one at the federal minimum, 14.3 SEER2$290 a year
  • An older air conditioner$330 a year

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

North Carolina requires HVAC contractors to hold a state license.

The board tests contractors before they get that license, then keeps a record of who holds one. It is tied to the contractor, not to the job, so the same license covers this repair and every other one they take on.

Anyone working on your air conditioner's refrigerant side also needs to hold EPA Section 608 certification, which is federal and applies no matter what state you're in. That covers the refrigerant work specifically. For a repair like this, the state license is what stands behind the contractor showing up at your door.

Why is my AC not blowing cold air?
Most often the filter is clogged enough to choke off airflow across the coil, or the refrigerant charge is low from a leak somewhere in the line. A dirty filter is worth checking yourself since it takes two minutes. Low refrigerant isn't something to top off and forget, since it means there's a leak that needs finding and sealing, and that work has to be done by someone with EPA 608 certification. If the filter looks fine and air is still coming out warm, especially on a 87°F afternoon, a licensed contractor needs to look at the coil and the charge.
Why is my AC leaking water?
Water on the floor near your indoor unit usually means the condensate drain line is clogged. Algae and dust build up inside that line over a cooling season and eventually block it, so the water backs up and finds another way out. A frozen coil that's thawing can also leave a puddle, and that points to a different problem, either low airflow or low refrigerant. Either way this isn't something to leave alone, since standing water can damage the floor or the unit itself.
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 temperature, and if it runs on batteries, try fresh ones. If the thermostat looks right, check your breaker panel, since a tripped breaker will shut the whole system down. When neither of those is the issue, it's likely something electrical inside the unit itself, like a failed capacitor or contactor, and that needs a licensed contractor to test and replace.
