Furnace Installation and Replacement Radnor
Heating Radnor's Older Stone Homes and Everything Built Since
Radnor's housing runs the gamut of the Main Line: stately older stone houses, mid-century colonials, and newer construction tucked between them. Each presents a different furnace installation problem. Thick masonry walls, additions stacked onto original floor plans, and basements never designed for modern mechanicals all shape what equipment fits and how it should be vented. PJ MAC HVAC Service & Repair has spent 32+ years installing heat in exactly this mix of buildings.
The House Decides the System
Many of the area's older stone homes were built without ductwork at all and heat with boilers and radiators — and we repair and replace those too. Where ducted heat exists, runs added over decades of renovations are often undersized or leaky. Before recommending anything for a Radnor property, we look at what the structure can actually support:
- ✓Existing ductwork capacity, condition, and missing return paths
- ✓Boiler-to-furnace questions in homes with radiator heat
- ✓Heat pumps and ductless mini-splits where ductwork was never installed
- ✓Chimney and sidewall venting options for high-efficiency units
- ✓Fuel type on site — natural gas or oil — and what conversion would involve
Right-Sizing Matters More in Older Construction
A load calculation on a 1920s stone house gives a very different answer than the same square footage built in 2005, because insulation, windows, and air sealing differ enormously. Installers who size by floor area alone routinely oversize equipment in Radnor, which means short cycling, uneven rooms, and wasted fuel. We measure the real heat loss and size to it.
Modern Equipment for Established Houses
We install gas and oil furnaces, boilers, and heat pumps from all major brands, including Lennox, Carrier, Trane, and Goodman, and every installation gets combustion and safety testing — including carbon monoxide checks — before we sign off. Owner Doug is a Master HVAC Technician, the company is family owned and operated, and the work is performed under PA License #PA157168.
Controls and Comfort in Larger Floor Plans
Bigger Radnor houses add a controls question on top of the equipment question. A single thermostat in a front hallway does a poor job governing a home with wings, additions, and three floors of bedrooms. During installation we can configure zoning, place sensors where people actually live, and set up modern thermostats that manage the new furnace intelligently. It is far easier to solve uneven comfort at installation time than to retrofit the answer two winters later, and it lets the new equipment deliver its efficiency on paper in practice.
