Heating & Cooling First
HVAC Service & Repair in West Chester
PJ MAC HVAC Service & Repair is a full-service HVAC contractor โ 24-hour AC and heating repair, installation and maintenance come first, backed by NADCA-standard air duct and dryer vent cleaning.



The homes around Westtown Park were built across a wide span of years, and the heating and cooling equipment inside them is just as varied โ central air retrofitted into an older house here, a modern heat pump in a newer build there. PJ MAC HVAC Service & Repair provides 24-hour AC and heating repair throughout Westtown Park, PA from our West Chester office, matching the work to the house in front of us. Reach a technician at (610) 424-6278.
Cooling Repair Shaped to Local Homes
In Chester County suburbs of mixed vintage, central cooling was often added long after the house went up, leaving tight equipment spaces, long line runs, and ductwork never designed for it. Those conditions wear a system down, surfacing as refrigerant leaks, failing compressors, bad capacitors, and coils frozen from restricted airflow. We diagnose the real fault and repair AC from every major brand โ Lennox, Carrier, Trane, and Goodman โ without forcing a single answer onto a Westtown Park home that doesn't fit it.
Furnaces, Boilers, and Heat Pumps Under One Roof Type or Another
Westtown Park heating equipment runs the full range: gas and oil furnaces, hot-water boilers in the older stock, and heat pumps in updated homes. PJ MAC repairs all of them. On any gas furnace we inspect the heat exchanger for cracks, since a damaged one can leak carbon monoxide, and we handle ignition faults, blower trouble, and boilers that knock or lose pressure โ so the heat suits how your particular home was built to be warmed.
Maintenance That Respects an Aging System
Homes of differing ages benefit most from steady upkeep, because small faults compound quietly in older equipment that has been patched over the years. Our HVAC tune-ups clean key components, check refrigerant charge and electrical connections, test safety controls, and flag worn parts before they leave you stranded on a hot or freezing day. For Westtown Park homeowners deciding whether to keep nursing an old unit along, we also offer free estimates on replacement and walk through the options without pressure, with new equipment carrying manufacturer warranties; our technicians are EPA 608 certified.
