Farmington doesn't ask much of an air conditioner

Summer afternoons here average 73°F. Most days don't call for cooling at all, and the compressor gets long stretches of rest.

The bigger risk to a system that runs this little is weather, not wear. Franklin County has seen 34 damaging wind events and 9 hail storms in the past ten years, with hail up to 1.75 inches. Wind can rattle the outdoor unit's cabinet and fins, and hail that size can dent them. A tune-up checks that the unit still sits level and sealed, and that nothing outside has been bent out of shape since it last ran.

What does AC maintenance include?
A technician checks refrigerant charge, cleans the condenser coil, tests the capacitor and contactor, and checks that the system cycles on and shuts off the way it should. They also check the filter and look at the drain line so condensation has somewhere to go. With summer afternoons here averaging 73°F, the system in a lot of Farmington homes doesn't run under real load very often, so this checkup is also when a technician catches corrosion or wiring issues before they'd ever show up as a breakdown.
How often does an air conditioner need maintenance?
Once a year is the standard, done before the weather turns warm. Farmington homes need active cooling essentially 0 months a year, so the unit sits idle most of the time, which makes that yearly check more about catching problems from sitting unused, corrosion, pests, loose wiring, than wear from heavy use. It's also worth having a technician look at the outdoor unit after any bad storm. This area has seen 34 damaging wind events and 9 hail storms over the past ten years, including one with hail up to 1.75 inches, and that kind of hail can dent or bend the fins on a condenser coil.
Is AC maintenance worth it?
Yes, even for a system that barely runs. A unit that sits idle most of the year is exactly the kind that can fail quietly, a stuck contactor, a nest built somewhere it shouldn't be, corrosion on connections that never get exercised. Given how often this area sees hail and high wind, a yearly check is also a chance to catch storm damage to the outdoor unit before it turns into a bigger repair.
