HVAC Service & Repair in Malvern
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.



When the heat or the cooling cuts out unexpectedly, waiting until morning isn't always an option. PJ MAC HVAC Service & Repair keeps a line open around the clock for emergency AC and heating repair in Frazer, PA, working from our Malvern office. Furnace dead overnight or air conditioner down in the heat โ call (610) 424-6448 and we can get a technician moving.
Cooling Down When the AC Suddenly Quits
A no-cool emergency usually hits during the hardest-working stretch of summer, when the system has been running flat out for days. If your Frazer system blows warm, trips the breaker, or ices the indoor coil solid, that is not something to ride out in the heat. We track the failure to its source โ a refrigerant leak, a dead capacitor, a failing compressor, or lost airflow from a dirty coil or filter โ and get cooling back, repairing it the same visit when we can. PJ MAC services all major brands, including Lennox, Carrier, Trane, and Goodman, so the make of your unit is never a reason to wait.
No Heat in Frazer After Hours
A furnace that dies on a cold Chester County night is an emergency we treat as one, because a house loses heat fast once the system stops. PJ MAC repairs gas and oil furnaces, boilers, and heat pumps for Frazer homes day or night. A no-heat call can come from a failed ignitor, a fuel issue, a tripped safety, or a worn boiler component, and we test for the real fault. Because it can also stem from a cracked heat exchanger, we check for carbon monoxide risk on every gas furnace; if the exchanger is compromised, we shut the unit down and explain why rather than restart something unsafe.
Stabilize Now, Decide on Replacement Later
The first priority on any Frazer emergency call is getting the home comfortable again. After that, we give you an honest read on whether the equipment has life left or is near the end. If replacement is the right move, we offer free installation estimates and size the system to the house. New equipment carries manufacturer warranties, and our technicians are EPA 608 certified.
