Four months of hard running, then months of sitting still

Your air conditioner only gets four months of work here, June through September, but it earns its keep. Summer afternoons average 84°F, and on those days the compressor runs long stretches to keep up. That kind of steady load wears on the parts that keep refrigerant moving and the coil clean.

Douglas County also sees its share of hail and wind. Ten years of storm records show 131 hail events and 138 damaging wind events, with hail up to 3.75 inches. That kind of weather can bend the fins on the outdoor coil or knock the unit out of level, and none of it announces itself until the system is straining on a hot afternoon. A tune-up before the season gets going is when a contractor finds a bent coil, a low refrigerant charge, or a fan motor working harder than it should, while it is still a small fix.

A tune-up checks the refrigerant charge, cleans the coils, tests the capacitor and tightens the electrical connections.

Nebraska requires contractors to register with the state.

The registration puts the business on file with the Department of Labor. Nobody tests the contractor's work to get on that list, and the state does not track how the contractor performs once they are on it. It is a record that the business exists, not a mark of skill.

For air conditioner maintenance, the thing that actually covers the refrigerant side of the job is federal, not state. Any technician who opens the sealed system to check or handle refrigerant has to hold EPA Section 608 certification, and that rule applies in Nebraska the same as it does everywhere else in the country.

What does AC maintenance include?
A technician checks refrigerant pressure, cleans the condenser coil outside, and checks the capacitor and contactor in the electrical parts. They also check the evaporator coil, clear the condensate drain line, and make sure the thermostat is calling for cooling correctly. Anyone opening the refrigerant side to check the charge has to hold EPA 608 certification, so this isn't a job for cleaning supplies and a Saturday afternoon. A clean coil and a clear drain line are what keep the system from working harder than it needs to.
How often does an air conditioner need maintenance?
Once a year, before the season it works hardest. Here that means getting it looked at before June, since the system runs from June through September and summer afternoons average 84°F. A yearly check catches a weak capacitor or a dirty coil before it fails on a hot afternoon instead of during it.
Is AC maintenance worth it?
Yes, mainly because it catches small problems while they're still small. A dirty coil or a capacitor going bad won't stop the system right away, but it makes it work harder, and that's how a minor issue turns into a breakdown during the summer. It also matters here because Omaha has had 131 hail events and 138 damaging wind events over the past ten years, and a maintenance visit is when a technician would notice a dented cabinet or bent fins from a storm before they cause a bigger problem. A contractor can price a maintenance visit for your specific system.
