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.



The furnace doesn't wait for business hours to die. It quits at 2 a.m. on the coldest night of January, or the AC gives out on the third day of a July heat wave with the whole house already baking. When that happens in Kensington, the only question that matters is who actually picks up the phone.
We Answer at 2 A.M. Because That's When It Breaks
PJ MAC HVAC Service & Repair runs 24-hour service from our Philadelphia office on Naudain Street, covering Kensington every day of the year. No-heat and no-cool calls get treated as what they are: urgent. We're family owned and operated, licensed under PA License #PA157168, and led by owner Doug, a Master HVAC Technician with more than 32 years of experience.
No Heat Is a Safety Problem, Not an Inconvenience
A Kensington rowhome loses warmth fast once the heat stops, and pipes, kids, and older family members can't just tough it out. We repair gas and oil furnaces, boilers, and heat pumps, handling the usual culprits like failed ignitors, pilot problems, and short cycling. Every furnace emergency includes a heat exchanger check, because a cracked exchanger can put carbon monoxide in your air and has to be caught immediately.
Heat Waves Punish Weak Air Conditioners
Brick rowhomes hold heat long after sundown, and an AC that limps through mild weather collapses when it's 95 outside. Dead capacitors, refrigerant leaks, frozen coils, and failing compressors top the list, and we diagnose and repair all of them, on all brands, including Lennox, Carrier, Trane, and Goodman.
- โFurnace or boiler down overnight in freezing weather
- โAC failure during an extended summer heat wave
- โHeat pump stuck and blowing the wrong temperature
- โBurning smells or suspected carbon monoxide concerns
- โMini-split failures in homes with no other cooling
What an Emergency Visit Looks Like
You call, we ask the right questions, and a technician comes to your Kensington address with the goal of restoring heat or cooling that visit. You get a clear explanation of the failure before work starts, and if the system is truly finished, we'll say so honestly and follow up with a free installation estimate rather than pressure you at midnight.
The Track Record Behind the Phone Number
A 5.0-star rating from 176 Google reviews is what 32+ years of showing up looks like. Kensington calls get the same response as every other block in Philadelphia: fast, competent, and straight with you. And when the emergency is over, maintenance tune-ups are how you keep your name off the 2 a.m. call list next season, catching the weak ignitor or tired capacitor before the weather finds it.
If your heat or AC just quit in Kensington, don't wait until morning. Call PJ MAC HVAC Service & Repair now at (610) 424-6447.
