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 mix of older and newer homes around Tatamy, PA means no two heating and cooling systems are quite alike, and PJ MAC HVAC Service & Repair is built for exactly that variety.

Reach our EPA 608 certified technicians at (610) 672-3055.
Comfort Solutions for Tatamy's Housing Mix
Some homes here were built before central air was standard and still rely on retrofit ductwork or boilers; others are newer builds with full HVAC systems. We work with whatever your house has, and for older homes without ductwork, ductless mini-splits often add cooling without tearing into walls. Every major brand is in our wheelhouse, including Lennox, Carrier, Trane, and Goodman.
Cooling Repair Across Every System Type
Whether your Tatamy home runs a central condenser or a mini-split head, we repair the same core faults: refrigerant leaks, failed compressors, weak capacitors, and frozen coils. We diagnose first so you are not paying for guesswork, then fix the actual problem and confirm the system holds before we leave.

Heating Repair for Furnaces, Boilers & Heat Pumps
Older houses often keep their boilers running for decades, while newer ones lean on furnaces or heat pumps. We repair all three, addressing ignition faults, circulator pumps, blower motors, and more. On any combustion appliance we inspect the heat exchanger and flag carbon monoxide risk if we find a crack.
Matching the Right System to the Right Home
Not every Tatamy home should be fixed the same way. An older house with a sound boiler may be worth keeping that system running for years, while a home limping along with an undersized retrofit might be better served by a ductless mini-split or a properly sized replacement. When repair no longer adds up, we provide a free estimate on equipment matched to your home, with manufacturer warranties on new equipment. As a family-owned company with 32 or more years in the trade, and with owner Doug a Master HVAC Technician, we size and recommend for the house in front of us, not a template.
Older homes deserve technicians who know how to work on aging systems without shortcuts. Our crew is EPA 608 certified for safe refrigerant handling, and PJ MAC carries PA License #PA157168. A 5.0-star rating from 176 Google reviews tells you how Tatamy-area neighbors feel about the result, whatever the age of their house.
