AC Repair in Radnor, PA
Radnor Township covers a wide range of housing, from substantial older homes to postwar development and newer infill, and the AC repair work reflects that spread. What the older properties share is that cooling was added to them rather than designed into them, and the air handler frequently ended up in the attic because it was the only place with room.
Attic air handlers drive a disproportionate share of the service calls we run in this township. PJ MAC covers Radnor from our Drexel Hill headquarters, 24 hours a day.
Condensate is the one that causes damage
An air conditioner pulls a substantial amount of water out of the air on a humid day, and all of it has to drain. When an attic unit's condensate line clogs — usually with biological growth in the drain pan and trap — the water goes somewhere else. In an attic installation, somewhere else is your ceiling.
Most attic units have a secondary pan and a float switch that should shut the system down before that happens. Those switches fail, get bypassed during a previous service call, or were never wired. If you have an attic air handler, whether that safety works is worth knowing before August rather than after.
Airflow through long attic duct
The other recurring Radnor issue is capacity that never reaches the room. Attic-mounted systems feed through duct that runs across the attic in the heat, and where that duct leaks or is poorly insulated the cooling is lost before it arrives. Homeowners experience it as a system that runs all day without satisfying and reasonably conclude the unit is undersized.
Sometimes it is. Frequently the equipment is adequate and the delivery is not. We measure airflow at the registers and static pressure at the handler to separate the two, because replacing correctly sized equipment does not fix a distribution problem.
What we service
All major brands, residential and commercial, with 24-hour emergency response. If a repair does not make economic sense we will say so and give you a free replacement estimate rather than putting parts into a system that is finished.
Radnor AC Repair — Questions We Get
I have an attic air handler. What should I be watching?
Condensate, mostly. A clogged drain line in an attic unit puts water through a ceiling. There should be a secondary pan and a float switch to prevent that, but those fail or get bypassed. Knowing whether yours works is worth checking before the humid season.
My system runs constantly and never quite cools the house.
That is often a delivery problem rather than a capacity problem, particularly with attic ductwork. Duct crossing a hot attic loses cooling before it reaches the register if it leaks or is under-insulated. We measure airflow and static pressure to tell whether the equipment or the distribution is the limit.
Should I just get a bigger unit?
Not before establishing why the current one is not keeping up. Oversizing a system that has a distribution problem makes comfort worse, not better — it short-cycles, removes less humidity, and still does not reach the rooms the duct cannot serve.
Do you handle commercial AC in Radnor?
Yes, residential and commercial both, with 24-hour service.
