Furnace replacements in St. Paul Park homes
Replacing a furnace in one of St. Paul Park's pre-1961 houses starts with the chimney. Keep an 80% furnace and the old masonry flue has to be inspected and often lined. Step up to a 96–98% model and it exhausts through PVC pipe instead, the condensate needs a floor drain or a pump, and the water heater left in the chimney may need a liner of its own. A Manual J often shows the old furnace was bigger than the house needed.
In the manufactured home community, the new furnace has to fit the closet and the floor duct opening, and its listing has to allow a manufactured-home installation with sealed combustion. Gas here comes from Xcel Energy. In a house this old the swap normally goes through the city's mechanical permit, and the written quote spells out what applies.

Furnace replacement in St. Paul Park: questions
Can a standard furnace go into our St. Paul Park manufactured home?
Usually not. Federal rules for manufactured housing require the furnace's combustion to be sealed off from the living space and the installation to follow the furnace's listing, and most furnaces sold for site-built houses aren't listed for manufactured homes. In practice that means a downflow furnace made for them, drawing combustion air from outside. We match the new unit to your closet, floor opening and AC coil, and quote it in writing before ordering.
We live in Stevens Ridge. Should the new furnace match the old one's size?
Not automatically. The furnace in a 1980s house has often been replaced once already, and each replacement tends to copy the label on the one before it. Meanwhile, many homes have gained new windows, extra attic insulation or a finished basement. A Manual J load calculation measures the house as it stands, and it often lands on a smaller furnace that runs longer, steadier cycles. We show you the numbers with the written quote.
