HVAC Service & Repair in Bala Cynwyd
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.



Pennsylvania asks a lot of a home's HVAC system โ humid summers that lean hard on the AC, then cold stretches that run the furnace for months. PJ MAC HVAC Service & Repair keeps Wynnefield Heights, PA comfortable through both with 24-hour AC and heating repair from our Bala Cynwyd office. Our family owned team brings 32+ years of seasonal experience; reach us at (610) 672-3049.
Summer Cooling Repairs
The first real heat of a Wynnefield Heights summer is when worn cooling systems give out โ they coast through mild spring weather, then fail the moment they're asked to run hard. A marginal capacitor, low refrigerant, or a tired compressor shows up exactly when you need cooling most. We repair every brand, Lennox, Carrier, Trane, and Goodman among them, and our EPA 608 certified technicians correct refrigerant issues so your system carries through the hottest weeks without quitting.
Heating Through the Cold Months
When the season turns, a furnace that sat idle all summer faces a long, demanding heating run. We repair gas and oil furnaces, boilers, and heat pumps, catching the problems that surface once the system is back under load. On every gas furnace we inspect the heat exchanger for cracks and confirm there's no carbon monoxide present โ a safety check that matters most in winter, when the heat runs daily and the house stays closed up.

Getting Ahead of the Season
The smartest time to deal with a marginal system is before the season tests it. A spring tune-up catches the weak cooling components that would otherwise fail in July; a fall check finds the heating issues that would surface on the first hard freeze. For Wynnefield Heights homeowners, that planning turns what could be an emergency into a scheduled, unhurried visit. And when a system has simply run out of seasons, we provide a free estimate on a replacement sized to handle Pennsylvania's full range of weather, with manufacturer warranties on the new equipment.
