Furnace repair calls in Little Canada homes
In Little Canada's single-family houses, a sizable share built before the early 1960s and many more before 1980, the basement furnace is well past its first replacement. Units that still vent into the original chimney fail at inducers, pressure switches and draft; units converted to PVC venting fail at condensate traps and drain lines. Control boards and igniters fail in both.
The rest of the city adds variety. Converted lake cabins put furnaces wherever the conversion allowed, sometimes in a crawlspace where access is tight and a condensate line can freeze. Large lake homes may run a zoned system, and a zone damper stuck shut looks like a dead furnace on that level. Condominium units come with association rules about who owns what. In the manufactured-home parks, repairs need parts that match furnaces listed for that construction.

Furnace repair in Little Canada: questions
One level of our zoned Lake Gervais home gets no heat, though the furnace runs. What's wrong?
Usually the zoning, not the furnace. A damper motor that has failed shut, a zone thermostat with dead batteries or a bad wire, or a zone control board that stops calling for that level will all leave one floor cold while the others heat. We check each thermostat's call at the zone board, then run every damper open and closed. Many dampers can be set open by hand as a stopgap until the motor is replaced.
Can you still find parts for the aging furnace that came with our Little Canada manufactured home?
Usually. Many manufactured-home furnaces use common igniters, flame sensors, limit switches and blower motors, and the model and serial number on the rating plate tell us what fits. Cabinet-specific pieces, like parts of the roof vent assembly or a particular control board, can take longer to find for an old unit. If the heat exchanger is cracked or key parts are gone, the replacement has to be another furnace listed for manufactured homes.
