Heating & Cooling First
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.



Comfort in a Whitemarsh Green home is about more than a number on the thermostat โ it's the air you actually breathe while the system runs. PJ MAC HVAC Service & Repair handles 24-hour AC and heating repair for Whitemarsh Green from our Bala Cynwyd office, and we pay attention to the things that quietly degrade comfort: weak airflow, lingering humidity, and dust that never seems to settle. If your equipment is running but the rooms still feel heavy, reach us at (610) 672-3049.
When Airflow and Humidity Point to a Repair
A struggling blower, a clogged coil, or a unit that's badly oversized will leave a Whitemarsh Green home damp in summer and stuffy in winter. We diagnose the mechanical cause rather than treating the symptom โ checking the blower motor, the evaporator coil, refrigerant charge, and the static pressure that decides whether conditioned air reaches every room. Better airflow usually means a more comfortable, healthier-feeling house.
Cooling Repair Across Every Brand
When the AC blows warm or freezes its lines, we trace it to the real fault โ a failed capacitor, a refrigerant leak, a seized compressor, or a frozen evaporator coil. Our technicians are EPA 608 certified for refrigerant handling and service Lennox, Carrier, Trane, Goodman, and the rest. A correct repair restores both temperature and the dehumidification a sticky Whitemarsh Green afternoon demands.
Furnace, Boiler, and Heat Pump Heating Repair
On the heating side we repair gas and oil furnaces, boilers, and heat pumps. Because a cracked heat exchanger can release carbon monoxide, we treat any odd furnace smell, soot, or short cycling as a safety check first and a comfort issue second. Restoring clean, even heat keeps a Whitemarsh Green home both warm and safe through the Montgomery County winter.
Maintenance That Keeps the Air Clean
A tune-up is the cheapest comfort upgrade most homes can make. A seasonal visit typically includes:
- โReplacing or upgrading filters to cut down on circulating dust
- โCleaning the indoor coil and clearing the condensate drain
- โChecking refrigerant charge and electrical connections
- โVerifying blower performance and overall airflow
- โConfirming the thermostat reads and cycles correctly
We can also talk through air duct cleaning when renovation dust or persistent allergens are part of the picture.
