Three months of heavy work, then hail season

Your air conditioner in Aurora earns its keep in a short window. June through August, with afternoons averaging 86°F, the compressor runs hard and often because there is no easing into it. Three months is all the time it gets to do a full year's worth of cooling.

Arapahoe County has also logged 175 hail events and 97 damaging wind events over the past ten years, with hail up to 3 inches. That kind of storm can dent the fins on your outdoor unit or bend the cabinet enough to affect airflow, even when the system still turns on and runs. A tune-up checks the coil and cabinet for that kind of damage, along with the refrigerant charge and electrical connections, before the next hot afternoon asks the unit to work through it.

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

What does AC maintenance include?
A contractor checks refrigerant pressure, cleans the condenser coil, and tests the capacitor and contactor. They also check the condensate drain for clogs and look at the electrical connections for wear. Outside, Aurora's hail and wind can dent the condenser cabinet or bend fins, so a visual check of the outdoor unit matters here too.
How often does an air conditioner need maintenance?
Once a year, before it has to run hard. Aurora only needs cooling from June through August, so spring is the time to have it checked, before those 86°F afternoons show up. A yearly check catches a weak capacitor or a dirty coil before the hottest part of summer.
Is AC maintenance worth it?
Yes. A dirty coil or a weak capacitor makes the system work harder and can lead to a breakdown right when you need cooling most. With only three months of real cooling weather in Aurora, a spring check means the system is ready for those months instead of failing partway through them.
