Five months of Hickory summer adds up fast
Your air conditioner runs May through September here. Summer afternoons average 87°F, and on those days the system cycles for hours at a stretch. That kind of run time wears on the parts carrying the load all season, like the refrigerant charge and the condenser coil.
Catawba County has also logged 66 damaging wind events and 32 hail events over the past ten years, some with hail up to 2 inches. A service visit is a chance to check the outdoor unit for damage from storms like those before the next one comes through.

A tune-up checks the refrigerant charge, cleans the coils, tests the capacitor and tightens the electrical connections.
North Carolina requires HVAC contractors to hold a state license.
The license comes from the State Board of Examiners of Plumbing, Heating and Fire Sprinkler Contractors, and it belongs to the contractor, not to any one job. That means the state tested this contractor before letting them take on work like yours, and keeps a record of who they are. It does not mean a fresh inspection happens every time someone comes to your house.
Maintenance on an air conditioner usually means opening up the refrigerant side of the system, checking pressures, maybe adding refrigerant. Any technician who does that, in North Carolina or anywhere else, has to hold EPA Section 608 certification. That is a federal rule, separate from the state license, and it covers the refrigerant work itself rather than the contractor as a business.

- What does AC maintenance include?
- A technician checks refrigerant charge, cleans the condenser coil outside, and tests the capacitor and contactor that start the compressor and fan. They also check the evaporator coil, clear the condensate drain so it isn't clogged, and confirm the thermostat is calling for cooling correctly. Anyone opening the refrigerant side of the system has to hold EPA Section 608 certification, so that part of the visit is never optional or skipped. The filter gets checked too, since a clogged one restricts airflow across the coil and makes the whole system work harder.
- How often does an air conditioner need maintenance?
- Once a year, ideally before the cooling season starts. Homes here run their air conditioner from May through September, so getting it checked in early spring means it's ready before the 87°F afternoons hit. A yearly check catches a weak capacitor or a dirty coil before it causes a breakdown in the middle of summer.
- Is AC maintenance worth it?
- Yes, because most of what causes a summer breakdown is something a technician can catch before it fails. A dirty condenser coil, a weak capacitor, or a low refrigerant charge all make the compressor work harder, and any of them can lead to it failing outright. This area has also seen 32 hail events and 66 damaging wind events over the past ten years, so a yearly check is also a chance to catch storm damage to the outdoor unit before it turns into a bigger repair.
