Furnace replacements in River Falls homes
In the older houses near downtown and the campus, a new furnace usually means a venting decision. A 96–98% furnace vents through PVC out a side wall and leaves the water heater alone in a chimney built for more, which calls for a liner or a power-vent water heater. In a rental with several furnaces sharing one chimney, taking one of them out of that chimney changes the venting for the rest, and the remaining appliances have to be rechecked.
Newer ramblers and two-stories often already have PVC, and the question becomes whether the old pipe size and run length meet the new furnace's instructions. Townhome associations may have rules about new wall penetrations. Focus on Energy's current rules are worth checking before you pick equipment. Check with the city or county for the mechanical permit.

Furnace replacement in River Falls: questions
Can our River Falls townhome association block a new wall vent?
It can control where the pipes go. Many associations treat exterior walls as common property, so a new PVC penetration needs approval before anything is cut. Ask the manager for the rules on penetrations, termination location and colors, and we supply the vent kit specs and a sketch of where the pipes will exit. If a wall exit isn't allowed, a roof termination or an 80% furnace venting into the existing flue may be the way around it.
Our River Falls rental has three furnaces in one basement. Do they all have to be replaced together?
No. Each furnace is judged on its own age and condition. The catch is venting. If all three vent into one chimney and one is replaced with a PVC-vented 96% furnace, the chimney now carries a different load, and the remaining furnaces and water heater have to be checked against the venting tables. Sometimes that means a liner or a connector change. We look at the whole basement before quoting even one furnace.
