Full-Service Air Conditioning Repair in Upper Darby, PA

Every fault falls into one of four buckets: electrical, airflow, refrigerant, or controls. Naming the bucket first stops a technician from replacing parts in hope. Tell the office what the equipment is doing when you book, because a condenser that trips the breaker leads somewhere different from one that never cools the room.

Outside Monday to Saturday, 8 a.m. to 5 p.m., cooling calls go to our 24-hour line. The extra rate that applies then is quoted on the phone, never added afterward.

Central Air Conditioning Repair

Failed capacitors, pitted contactors, and tired condenser fans account for most AC repair work booked here between June and September. Those three are carried on the van, so a diagnosis in the morning does not become a return visit on Thursday.

Air Handler Repair and Replacement

Blowers, wheels, and control boards sit indoors in an attic or a closet nobody opens. Air handler repair starts with a current reading and a look at the wheel, because a grimy blower wheel shifts far less air than it should while sounding perfectly healthy.

Evaporator Coil Cleaning and Repair

A coil furred with dust cannot absorb heat, so the house stays warm while the equipment runs flat out. Evaporator coil repair is worth doing where the coil is sound, and the fins are blocked. Where it has corroded through, evaporator coil repair is no longer sensible, and we price a replacement instead.

AC Refrigerant Leak Detection and Repair

Refrigerant is not a consumable. If a system is low, the gas went somewhere, so AC refrigerant leak repair begins with finding the hole. AC refrigerant leak repair, done properly, ends with a pressure test rather than a top-up, and a booking for next summer.
