Five months of hard running takes its toll
Your air conditioner works from May through September here, and on an afternoon at 86°F it doesn't get much of a break. The compressor runs long and often just to hold the house steady, and that kind of stretch wears on it faster than a mild summer would.
Mooresville has also seen 105 damaging wind events and 22 hail storms over the past ten years, with hail up to 2 inches. The outdoor unit sits outside through all of it, and hail can bend the thin fins on the coil while wind can carry debris right into the cabinet. You'll notice the effects as weaker cooling on the hottest afternoons, or the unit running longer than it used to just to keep up.

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 state board tests contractors before they hold that license, and it keeps a record of who passed. The license covers the contractor, not the job, so the same one applies to a repair like this and to any other HVAC work that contractor takes on.
Anyone who opens the refrigerant side of your air conditioner also needs EPA Section 608 certification. That rule comes from the federal government, not the state, and it applies everywhere in the country. The state license says the contractor was tested and is on record. The federal certification says whoever handles the refrigerant was trained to do it without venting it into the air or damaging the coil.

- Why is my AC not blowing cold air?
- The most common cause is low refrigerant from a leak, a dirty filter cutting off airflow, or ice built up on the coil. A dirty filter is worth checking first since you can see it yourself. If the coil is frozen or the lines are frosted, the system needs a licensed technician, since only someone with EPA Section 608 certification can legally open the refrigerant side.
- Why is my AC leaking water?
- Warm, humid air runs across the evaporator coil and the moisture that condenses out has to drain somewhere. If the drain line or drain pan is clogged or cracked, that water backs up and shows up inside your house instead. A clogged line is the usual reason, and it needs to be cleared before the leak stops.
- Why won't my AC turn on?
- Start with the thermostat batteries and the breaker panel, since both are common culprits and both are things you can check yourself. If those are fine, the problem is likely inside the unit, in the capacitor, the contactor, or the control board, and that calls for a licensed contractor to diagnose. In North Carolina, whoever comes out to look at it has to hold a state HVAC contractor license.
