Heating & Cooling First
HVAC Service & Repair in Bryn Mawr
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 older stone homes of Gladwyne are beautiful and demanding, often built before central air and short on the duct runs modern systems expect. PJ MAC HVAC Service & Repair understands that housing and brings 24-hour AC and heating repair to Gladwyne, PA from our Bryn Mawr office. Call our family-owned team at (610) 424-6452. With 32 years on Main Line homes and EPA 608 certified technicians, we fit the solution to the house.
Cooling Homes That Were Never Built for Ducts
Many homes here lack the wide chases that central air wants, which is where ductless mini-splits earn their keep, cooling rooms without tearing into plaster and stone. We also repair existing central AC across all major brands, Lennox, Carrier, Trane, and Goodman, and we know the airflow challenges these thick-walled houses create.
- โStone and plaster walls that make adding ductwork costly and disruptive
- โFinished older basements where furnace and AC access is tight
- โAdditions and converted spaces that the original system never reached
- โRooms that run hot or cold because the home grew over decades
Heating the Character Home
Gladwyne's older houses often run on boilers or aging furnaces, and some still burn oil. We repair gas and oil furnaces, boilers, and heat pumps, and on every furnace and boiler call we inspect the heat exchanger and flue for cracks or leaks that could send carbon monoxide into living space. Older homes deserve that extra safety check.
Repair Versus Replacement in an Older Home
Decades-old equipment eventually reaches a point where another repair is not the smart call, and we will tell you honestly when that point arrives. For a character home, replacement also raises questions a newer house never faces: where the new equipment will sit, how to route refrigerant lines without disturbing finished stone, and whether a ductless system fits better than forcing in ductwork. We give free estimates on new equipment, walk through the trade-offs, and size every system to the home rather than to a sales target. New systems carry manufacturer warranties on the equipment.
Maintenance for Long-Lived Equipment
Older equipment can serve for many more years when it is looked after. Seasonal tune-ups keep an aging furnace or AC running efficiently and catch wear before it becomes a breakdown, and on the heating side we re-check the heat exchanger and flue each season for safety. We tailor maintenance to the system you have rather than pushing a one-size plan.
