Heating & Cooling First
HVAC Service & Repair in Allentown
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.



A home in this part of Pennsylvania runs its air conditioning hard through humid summers, then leans on the furnace through long, cold winters โ two seasons that each test the equipment in their own way. PJ MAC HVAC Service & Repair offers 24-hour AC and heating repair throughout Cherryville, PA from our Allentown office, ready for whichever one is straining your system. Call (610) 672-3042.
Summer Demand on an Air Conditioner
When humidity builds across Cherryville, an air conditioner runs for hours at a stretch, and that sustained load is when weak parts surrender. We commonly find refrigerant leaks that leave the system unable to keep up, capacitors that won't start the compressor, and coils that freeze when airflow falls off on the hottest days. PJ MAC pinpoints the cause and repairs cooling equipment from all major brands โ Lennox, Carrier, Trane, Goodman โ so summer doesn't leave you sweating it out.
Heat That Holds Through a Long Winter
Cherryville winters keep heating systems running for months, and a furnace that limped through the end of last season often quits on the first deep freeze. We repair gas and oil furnaces, boilers, and heat pumps, and on gas equipment we inspect the heat exchanger for cracks that can release carbon monoxide. Catching ignition trouble, a worn blower, or a strained heat pump before the cold sets in keeps a small repair from becoming a no-heat night.
Tuning Up for the Season Ahead
Because Cherryville equipment swings between two punishing seasons, a tune-up before each one earns its keep. Our maintenance visits clean and test the system, verify refrigerant and electrical health, and flag parts unlikely to make it through another summer or winter. When a unit has run its course, we offer free estimates on right-sized replacement, with manufacturer warranties on new equipment, and our technicians are EPA 608 certified.
Heat Pumps in a Four-Season Climate
More homes here rely on heat pumps now, and they have to work in both directions across the year โ cooling all summer, then heating through the cold. That dual duty means they log more hours than a system that only runs half the year, and small efficiency losses show up sooner. We repair heat pumps for both modes, restoring proper refrigerant charge and defrost operation so the unit keeps pace whether it's August or January in your Cherryville home.
