Five months of hard running in Lancaster County heat

Your air conditioner works from May through September here, and on a lot of those afternoons it's pushing against 89°F outside. That's five straight months where the system barely gets a break, cycling on and off all day to keep the house down.

All that runtime wears on parts a yearly tune-up is built to catch. A technician checks the refrigerant charge, cleans the coil, and tests the capacitor before any of it turns into a system that won't start on the hottest day of the year. Lancaster County has also seen its share of hail and wind over the past ten years, so a maintenance visit is also a chance to check the outdoor unit for storm damage before it turns into a bigger repair.

5 months: May through September, your air conditioner is on duty
89°F: the average summer afternoon it cools against
46 hail events: in ten years, and hail bends the fins on outdoor coils
133 wind events: in ten years, and wind drives debris into outdoor units

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

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 charge, cleans the condenser coil, and tests the capacitor and contactor in the outdoor unit. Indoors, they check the evaporator coil and the drain line, since a clogged drain line backs up and can trip the float switch. They also check the filter, though that's something you can check yourself between visits. Airflow and temperature readings at the vents tell them whether the system is cooling the way it should.
How often does an air conditioner need maintenance?: Once a year, in spring before the heat sets in. Lancaster homes run the AC from May through September, so getting it checked beforehand means it's not straining on the first 89°F afternoon. A yearly check also catches a weak capacitor or a low refrigerant charge before it leaves you without cooling mid-summer.
Is AC maintenance worth it?: Yes, because most breakdowns start as a small problem that maintenance catches early. A failing capacitor or a dirty coil gets found in spring instead of failing outright once the heat is on. With five months of cooling ahead each year here, and afternoons regularly hitting 89°F, a system that's already been checked over is one you can count on when you need it most.
