Five months of Concord summers add up fast
Your air conditioner works hardest from May through September, and on afternoons that hit 88°F it runs long stretches just to keep the house comfortable. That kind of steady demand puts real hours on the compressor and the fan motor, more than a system in a milder climate would ever see.
Cabarrus County has also logged 26 hail events and 60 damaging wind events over the past ten years, with hail up to 2.75 inches. Outdoor units sit exposed to all of that. A tune-up checks the coil fins and the condenser cabinet for damage that storms leave behind, along with the wear that a long, hot cooling season puts on the parts that keep the system running.

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 is held by the contractor, not issued job by job, so it is the business and the person running it that the state has tested and put on record, not this particular visit. The Board keeps that record for anyone who wants to check who they are letting into their home.
For a maintenance visit on an air conditioner, the license covers who is allowed to run the business doing the work. If the technician opens the refrigerant side of your system to check the charge, federal law requires EPA Section 608 certification to do that, the same as it would in any other state.

- What does AC maintenance include?
- A technician checks the refrigerant charge, cleans the condenser coil, and tests the capacitor and contactor in the outdoor unit. Inside, they check the evaporator coil and the condensate drain, since a clogged drain is one of the most common reasons an AC stops cooling. They also check the thermostat and airflow, and change or check the filter. Any work on the refrigerant lines has to be done by someone with EPA Section 608 certification, which is a federal requirement for every technician, everywhere.
- How often does an air conditioner need maintenance?
- Once a year, ideally before the season starts. Homes here run their AC from May through September, so having it checked in spring gives a technician time to catch a weak capacitor or a low refrigerant charge before the heat sets in. Skipping a year does not always cause a breakdown, but it means small problems go unnoticed longer.
- Is AC maintenance worth it?
- Yes, because most of what causes a summer breakdown is something a technician can catch ahead of time. A dirty coil, a failing capacitor, or a clogged condensate drain all show up during a maintenance visit, before they leave a house without cooling. That matters more here than in mild climates, since summer afternoons average 88°F and the system runs hard for five months straight.
