Heating & Cooling First
HVAC Service & Repair in Paoli
PJ MAC HVAC Service & Repair is a full-service HVAC contractor — 24-hour AC and heating repair, installation and maintenance come first, backed by NADCA-standard air duct and dryer vent cleaning.
Wayne sits across Radnor and Tredyffrin Townships on the Main Line, and its housing runs from substantial older stone and shingle homes to postwar development and newer infill. Almost none of it was built with central air, and much of it has been through more than one heating system, so the HVAC we work on here is layered — equipment from different decades fitted into structures that were designed around none of it.
PJ MAC covers Wayne from our Paoli office on South Valley Road. We answer the phone 24 hours a day, we work on every major brand, and estimates on installation work are free.

Retrofit systems and their limits
Because cooling in Wayne is almost always a retrofit, the duct is usually the constraint rather than the equipment. Systems were fitted through closets, knee walls and attic space, with longer runs and more bends than a purpose-built installation would have. That leaves little margin, and it means a comfort complaint here is more often a distribution problem than a capacity problem.
It matters because the two have very different costs. We measure airflow at the registers and static pressure at the air handler before recommending equipment, since a larger system does not overcome a restriction.
Attic air handlers
A lot of Wayne homes have the air handler in the attic, which introduces a specific risk: condensate. When the drain line on an attic unit clogs, water goes into the ceiling below. Most installations have a secondary pan and float switch to prevent that, but those fail or get bypassed. If you have attic equipment, it is worth confirming that safety works before the humid season rather than after.
Straight answers
We are not a single-manufacturer dealer, so what we recommend is not shaped by a dealer agreement. Where a repair makes sense we repair it; where a system is genuinely finished we say so and the replacement estimate is free.

Frequently Asked Questions
Do you cover Wayne 24 hours a day?
Yes. We answer calls 24 hours a day, seven days a week, and dispatch from our Paoli office on South Valley Road, which is a short run into Wayne.
A room in my house has never been comfortable. What is that?
In Wayne housing that is usually distribution rather than capacity. Cooling here is nearly always a retrofit, so duct was fitted through closets, knee walls and attic space with long runs and many bends. We measure airflow and static pressure before recommending equipment, because a larger system does not overcome a restriction.
I have an attic air handler. What should I watch for?
Condensate. A clogged drain on an attic unit puts water through the ceiling below. There should be a secondary pan and float switch to prevent it, but those fail or get bypassed during earlier service. Confirming yours works is worth doing before the humid season.
Do you install ductless mini-splits?
Yes. They are frequently the right answer for additions, converted spaces and rooms where running conventional duct would mean losing closet space on every floor.
Which brands do you work on?
All the major ones — Lennox, Carrier, Trane, Goodman and others. We are not tied to a single manufacturer.
