Heating & Cooling First
HVAC Service & Repair in Bethlehem
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.



Efficient equipment and clean, balanced air are what make a Ferndale, PA home feel right, and PJ MAC HVAC Service & Repair delivers both. From our Bethlehem office we run 24-hour AC and heating repair with an eye on how the system breathes, not just whether it runs. Our family-owned, EPA 608 certified team picks up at (610) 672-3055.
Cooling Repair That Restores Efficiency in Ferndale
A system limping along on low refrigerant or a dirty coil works harder and circulates poorly. We repair refrigerant leaks, failed compressors, weak capacitors, and frozen coils on all major brands, including Lennox, Carrier, Trane, and Goodman, so your Ferndale home cools efficiently and the air moving through it stays fresh.
Heating Repair With Air Quality in View
Gas and oil furnaces, boilers, and heat pumps all benefit from a clean, well-tuned setup. We fix ignition faults, dirty burners, and blower problems, and we inspect the heat exchanger every visit. A crack there can release carbon monoxide into your air, so we check carefully and report findings plainly to keep your Ferndale home safe.
Filtration, Humidity & Cleaner Indoor Air
The HVAC system is your home's lungs, and we help Ferndale households get more from it. Better filtration captures more dust and allergens, while humidifiers and dehumidifiers keep moisture in the comfortable range through the year. When buildup in the ducts is the real issue, air duct cleaning is available too.
- โUpgraded filters for more dust and allergen capture
- โHumidity control for dry winters and muggy summers
- โTune-ups that keep coils and blowers running clean
- โBalanced airflow to cut down on stale, stuffy rooms
Efficiency and Air Quality Go Hand in Hand
A system that runs clean runs efficient, and one that runs efficient tends to keep the air healthier too. The same dirty coil that wastes energy also chills the air unevenly and lets moisture linger where it should not. Keeping the equipment tuned solves both problems at once. As a family-owned company with 32 or more years in the trade, and with owner Doug a Master HVAC Technician, we look at the whole picture rather than chasing one number on a thermostat.
Efficiency and indoor-air work both depend on technicians who know refrigerant and airflow cold. Ours are EPA 608 certified for safe refrigerant handling, and PJ MAC carries PA License #PA157168. A 5.0-star rating from 176 Google reviews reflects what local homeowners think of the comfort and air quality we leave behind.
