Furnace replacements in Excelsior homes

A furnace replacement in an Excelsior Victorian is largely a fitting problem. The new unit has to stand under a low ceiling with room for the AC coil and filter rack, and the ductwork threaded through closets and old chases has to deliver the airflow the new blower expects. Manual J sizing matters in these houses: plaster walls and old windows lose heat, but decades of added insulation mean the old nameplate is rarely the right answer.

Moving from an 80% furnace to a 96% model means PVC intake and exhaust through the rim joist above a fieldstone or block wall, with clearances from windows on your house and the one next door. The water heater left in the old chimney usually needs a liner. Expect the swap to need a mechanical permit from the city.

Furnace replacement in Excelsior: questions

Could we replace the boiler in our Excelsior house with a furnace?

It can be done, but it's rarely the easy path. A radiator house has no ductwork, so switching to a furnace means running supply and return ducts through plaster walls, closets and floors, which is slow and disruptive. Most owners keep the boiler, which gives even, quiet heat, and add cooling separately with ductless heads or a small-duct system. If the house already has partial ductwork from an earlier conversion, the math changes, and we look at that first.

Will a furnace replacement in our old Excelsior house mean opening plaster walls?

Usually not. The furnace swap happens in the basement: disconnect the old unit, set the new one, reconnect the ducts, gas and power, and run the PVC venting through the rim joist. Walls only come into it if the ductwork itself needs changes, such as adding a return to a room that's always cold. When that's worth doing, we show you the route first and list it in the quote as a separate line.
