Heating & Cooling First
HVAC Service & Repair in Bryn Mawr
PJ MAC HVAC Service & Repair is a full-service HVAC contractor — 24-hour AC and heating repair, installation and maintenance come first, backed by NADCA-standard air duct and dryer vent cleaning.
Villanova properties are larger than average and are frequently served by multiple systems — separate equipment for different wings and floors, often installed years apart and sometimes by different contractors. That single fact shapes most of the HVAC work we do here.
PJ MAC covers Villanova from our Bryn Mawr office on West Lancaster Avenue, 24 hours a day, on every major brand.

Knowing which system serves what
On a property with three or four systems, the first job is establishing which equipment feeds the room that is not conditioning. It sounds elementary and it is repeatedly the step that gets skipped — a previous contractor services the accessible unit rather than the responsible one, and the complaint survives the repair.
We map the property before diagnosing. Once that is right, the rest is straightforward; without it everything downstream is guesswork.
Mixed-age equipment
When systems were installed years apart, they reach end of life years apart too. That creates a planning question rather than just a repair question: if one of four systems has failed and another is close behind, addressing both while access is open and a crew is on site usually costs meaningfully less than two separate projects.
We will document the condition and remaining life of each system so you can make that call with real information. We are not tied to a single manufacturer, so the recommendation is not shaped by a dealer agreement.
Older stone construction
Thick masonry walls, limited chase space and rooms never intended to be ducted make retrofit distribution in these homes less forgiving than modern construction. Where a room underperforms, the duct is worth examining before the equipment — and where duct genuinely cannot reach a space, a mini-split is often the honest answer rather than more duct.

Frequently Asked Questions
I have several systems and do not know which serves the problem room.
That is normal on larger Villanova properties and it is the first thing we establish. Servicing the accessible unit rather than the responsible one is a common and expensive mistake, so we map which equipment feeds which zone before diagnosing anything.
Should I replace more than one system at once?
It is worth considering when systems are close in age. Addressing two while access is open and a crew is on site usually costs meaningfully less than two separate projects. We will document condition and remaining life on each so you can decide with real information.
A room in the older wing never conditions properly.
In retrofit distribution through thick masonry, that is usually the duct rather than the equipment. Where duct genuinely cannot reach a space well, a ductless mini-split is often the honest answer rather than more duct.
Do you work on hydronic and boiler systems?
Yes — gas and oil furnaces, boilers, hydronic zones and heat pumps.
