Three months of hard running, then months of sitting still

Your air conditioner in Broomfield only has to earn its keep from June through August. On afternoons averaging 86°F, it runs hard for those three months, then sits idle the rest of the year. That kind of stop-and-start life, all effort packed into one short stretch, is what a tune-up is built to check on. A technician can catch a weak capacitor or a low refrigerant charge before the first hot week finds it for you.

Broomfield has also seen 17 hail events and 60 damaging wind events over the past ten years, with hail up to 1.5 inches. The outdoor unit sits outside through all of that. A maintenance visit is a chance to look over the coil and cabinet for dents or bent fins from wind-blown debris, the kind of damage that can restrict airflow long before it causes a breakdown.

17 hail events: in ten years, and hail bends the fins on outdoor coils
60 wind events: in ten years, and wind drives debris into outdoor units

Book your AC tune-up in May, before homes here start needing cooling in June.

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

What does AC maintenance include?: A technician checks refrigerant pressure, cleans the condenser coil, and tests the capacitor and contactor that start the compressor. They also check the fan motor, inspect the electrical connections for wear, and change or clean the filter if it's dirty. Low refrigerant or a dirty coil both make the system work harder to cool the same house, so catching those early is most of the point of the visit.
How often does an air conditioner need maintenance?: Once a year is enough for most homes. Spring, before the heat starts, is the best time so any problem gets caught before you need the system. Homes here only run the AC from June through August, so a spring check gives a contractor time to order a part if something needs replacing before the first hot afternoon.
Is AC maintenance worth it?: Yes, because most of what causes a summer breakdown is something a technician can catch before it fails. A weak capacitor, a dirty coil, or a low refrigerant charge all show up during a check, and any one of them can leave you without cooling on an afternoon that hits 86 degrees. Summers here are short, just three months, so there isn't much room to lose a week of it waiting on a repair.
