Heating & Cooling First
HVAC Service & Repair in Philadelphia
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.



Philadelphia's housing stock doesn't look like the suburbs', and its HVAC problems don't either. Block after block of rowhomes — many of them a century old or more — means narrow basements, tight utility closets, party walls, flat roofs, and mechanical systems shoehorned into spaces never designed for them. Repairing heating and cooling equipment in Philadelphia is a specialty of its own, and it's one PJ MAC HVAC works in every day from our office at 130 Naudain St #202.
What Rowhome Construction Demands of a Technician
In a typical Philadelphia rowhome, the furnace or boiler lives in a compact basement with minimal clearance, the ductwork — when there is any — threads through chases and joist bays, and the AC condenser may sit in a small rear yard or up on the roof. Working in those conditions takes patience, the right tools, and experience with older buildings. Our technicians bring 32+ years of company experience to those tight mechanical spaces, led by owner Doug, a Master HVAC Technician.
Heating Repair for Older Philadelphia Systems
Plenty of the city's homes still heat with boilers and radiators, while others run gas furnaces of varying vintage or heat pumps added in later renovations. PJ MAC repairs all of it — gas and oil furnaces, boilers, and heat pumps — and pays particular attention to aging furnaces, where a cracked heat exchanger can introduce carbon monoxide into a home. In densely built rowhome blocks, that safety check matters even more.
Cooling a House That Was Built Before AC
Many Philadelphia homes were standing long before central air existed, and some have no ductwork at all. Where ducted central air is in place, we repair it — compressors, capacitors, refrigerant leaks, frozen coils. Where it isn't, ductless mini-splits are often the natural fit for rowhome layouts, and we service and install those too. Free installation estimates make it easy to compare paths.
