Furnace repair calls in Northfield homes
Furnace repair near downtown Northfield and the colleges often means a tall old house, a chimney that climbs three stories, and forced air that replaced a gravity furnace generations ago. A tall masonry chimney with one furnace attached can run cold and draft poorly; the evidence is a tripped spill switch or a water heater that backdrafts when the furnace kicks on. We test draft and measure CO around both appliances.
Houses split into apartments add their own layer: two or three furnaces sharing a basement, sometimes sharing a flue, and tenants who can't reach the filter. Those furnaces run hard and get less attention, so we find plugged filters, overheated heat exchangers and worn inducers. Farther from downtown, the mid-century ramblers and the 1990s and 2000s subdivisions bring the familiar igniter, flame sensor and condensate-trap calls. Xcel Energy supplies the gas across town, and no-heat calls get priority.

Furnace repair in Northfield: questions
Why does our old Northfield house smell like exhaust when the furnace starts?
Treat it seriously. It can mean the chimney isn't drafting at startup, so combustion gases spill out of the water heater's draft hood or the furnace flue connection. Tall masonry chimneys on older houses can be slow to warm, and a blockage or a cracked heat exchanger can cause the same smell. Check your CO alarms, and have the draft and heat exchanger tested. If readings are unsafe, the appliance gets shut off.
We rent out a Northfield house with several furnaces. How do we catch a failure before the tenants do?
A Wi-Fi thermostat on each furnace can alert you when a unit stops holding temperature, often before a tenant calls on a cold morning. Filters are the other weak spot in rentals, so a media filter cabinet that needs changing only once or twice a year helps. Ask us about a maintenance plan for multi-furnace buildings, and we'll write up each furnace's condition separately.
