Heating & Cooling First
HVAC Service & Repair in Philadelphia
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 furnace that dies on a January night or an air conditioner that quits during a July heat wave does not wait for business hours โ and in Haverford North, neither do we. PJ MAC HVAC Service & Repair runs a true 24-hour operation, so when your home goes cold or hot at the worst possible moment, a real person answers and a repair gets moving.
No Heat in Haverford North? Here Is What to Do
Before you call, check the basics: the thermostat batteries, the breaker, and the furnace switch that looks like a light switch near the unit. If those are fine and you still have no heat, stop there โ repeatedly cycling a failing furnace can make things worse. We repair gas and oil furnaces, boilers, and heat pumps across Haverford North, whatever brand is in your basement, including Lennox, Carrier, Trane, and Goodman.
Cooling Failures During a Philadelphia Heat Wave
Older homes in this part of West Philadelphia hold heat, and an upstairs bedroom can become unlivable fast when the AC drops out. Common culprits we find on emergency calls are failed capacitors, tripped compressors, refrigerant leaks, and frozen evaporator coils. Each has a different fix, and guessing wrong wastes a miserable night โ so we diagnose first and repair what is actually broken.
What 24-Hour Service Means at PJ MAC
It means the phone is answered around the clock, every day of the year, from our Philadelphia office at 130 Naudain St #202. It does not mean a call center that takes a message for the morning. Emergencies worth calling about at any hour include:
- โNo heat in freezing weather, especially in a home with kids or older family members
- โNo cooling during an extreme heat event
- โA furnace that is short-cycling, booming, or producing a burning smell
- โWater pooling around a boiler or air handler
- โAn outdoor unit that hums but never starts
When to Shut the System Down and Step Away
If a carbon monoxide alarm sounds, leave the house and call for help before calling us. A cracked heat exchanger can allow combustion gases into your air supply, which is why our furnace diagnostics always include a careful inspection of the exchanger. It is the one repair question where caution always wins.
