Furnace repair calls in Medina homes
Medina's housing runs from Hamel's village houses near Highway 55 to large custom homes on acreage, and furnace repair looks different at each end. The bigger homes built since the 1990s commonly have two furnaces: one for the main and upper floors, one for a zoned lower level. The lower-level furnace runs less, so a weak igniter or a plugged condensate trap can go unnoticed until the first real cold snap. Zone dampers add another failure point, and a damper motor stuck closed looks exactly like a furnace that won't heat one floor.
On outlying acreage the furnace may burn propane, and older farmhouses often have one furnace feeding ducts that were added onto over the years. A heated garage or shop brings its own unit heater. We test the full startup sequence on whichever system called, check the zone controls, and write the repair price before replacing anything.

Furnace repair in Medina: questions
One floor of our Medina house is cold, but the furnace is running. What's wrong?
In a zoned house, that's often a damper rather than the furnace. Each zone has a motorized damper in the ductwork that opens when its thermostat calls. A damper motor that fails closed, a loose wire at the zone panel, or a thermostat with dead batteries can leave one floor cold while the furnace runs normally for the other. We check the zone panel and dampers before touching the furnace, which often saves a bigger repair.
Our Medina garage heater won't light. Do you work on those too?
Yes. Gas and propane unit heaters in attached and detached garages use many of the same parts as a furnace: an igniter, a flame sensor, an inducer and a limit switch. The common problems are dust and cobwebs in the burner, a blocked vent, and a thermostat mounted where the overhead door dumps cold air on it. The same $79 trip charge applies, waived with the repair, and the price is written first.
