Princeton is a single consolidated municipality today, and its housing covers nearly every era: eighteenth and nineteenth century homes around the university and Nassau Street, early twentieth century houses in the Witherspoon-Jackson and Western sections, and much larger newer construction toward the outer edges. The old houses have hot-water or steam heat, plaster walls and no ducts anywhere, while the newer ones have three zones and a mechanical room. Working on the old ones without taking the house apart is its own skill.

What We See in Princeton Homes & Buildings
- Radiator heat and no ductwork is the normal starting point in the older parts of town, which is why ductless and small-duct cooling come up so often in Princeton.
- In the historic districts, what can change on the exterior matters — condenser placement, vent terminations and line-set routing all get worked out before anything is ordered.
- Century-old supply piping shows itself as weak flow and pinhole leaks, and we can stage a repiping so a family keeps living in the house while it happens.
Sections of Princeton we serve include Witherspoon-Jackson, Riverside, Littlebrook, along with every other part of the borough.

Princeton Plumbing & HVAC FAQs
Can an older Princeton house with radiators and no ducts get air conditioning?
Yes, and there is more than one way to do it. Ductless indoor units handle room-by-room cooling with minimal disruption, and where there is attic or closet space a compact ducted system is sometimes possible instead. We look at the house before recommending either.
We want to keep our radiators but the boiler is ancient. What are the options?
Keeping the radiators is entirely reasonable — a modern high-efficiency boiler will run them, often with an indirect tank for domestic hot water. We calculate the heat loss first so the new boiler matches the house rather than the old nameplate.
How do you protect plaster and floors when running new pipe or a line set?
We plan the route to use the fewest, smallest access openings we can, protect floors and finishes on the way in and out, and agree with you in advance on who patches what. In a house with original plaster that conversation happens before we start, not after.
