Furnace repair calls in River Falls homes
River Falls furnaces split along the Kinnickinnic. Near downtown and the UW–River Falls campus, older houses carry furnaces that replaced gravity heat, squeezed into small basements with low beams and a chimney shared with the water heater. Some of those houses are rentals divided into apartments, with two or three furnaces lined up in one basement and a thermostat in each unit, and the first job on a no-heat call is matching the thermostat to the furnace.
The subdivisions built from the 1970s on have ramblers and two-stories with basement furnaces, many now on 90%-plus equipment with PVC venting, plus townhomes where the furnace sits in a closet or small utility room. Those bring condensate trap clogs, igniter and flame sensor failures, and inducer motors that start to whine before they quit. Western Wisconsin winters bring the same sub-zero stretches as the Twin Cities, so a furnace that limps through November tends to give out in January.

Furnace repair in River Falls: questions
I own a River Falls rental with a furnace for each apartment. Can you look at all of them in one visit?
Yes. We can check every furnace on the same visit, and each repair gets its own written, flat-rate price before work. It helps to label which furnace serves which unit and to have tenant access arranged. For rentals near campus, we also point out things that cause repeat calls, such as filters nobody changes, returns blocked by furniture, and CO alarms that need replacing, so the next no-heat call is less likely.
Who do I call first if I smell gas near my River Falls furnace?
Your gas utility, from outside the house. In River Falls that's St. Croix Gas. Don't flip light switches or try to relight anything; leave, then call. The utility checks for the leak and shuts off the gas if needed. Once the gas side is safe, we repair the furnace itself, whether it's a loose union at the gas valve, a failed valve or something else the utility found.
