Furnace repair calls in Hanover homes
Many Hanover furnaces are the first ones the house ever had, put in as the subdivisions went up from the late 1990s on. Past twenty years, the usual failures are an inducer motor with worn bearings, a hot-surface igniter that has cracked, a brittle pressure-switch hose or a control board that finally quits. Each of those is a normal repair. The bigger question is whether the heat exchanger and blower have more winters in them, and we tell you what we see.
Walk-out lots add a wrinkle. The furnace usually sits in a mechanical room behind the finished lower level, and a chilly walk-out in January is more often a duct and sizing issue than a broken furnace. On the acreage around town, a propane furnace that locks out on a cold night can simply mean the tank is low, so check the gauge before you call.

Furnace repair in Hanover: questions
Can you still get parts for a late-1990s furnace in Hanover?
Usually, yes. Igniters, flame sensors, inducer motors, pressure switches and limit switches for furnaces of that age are still easy to find, either from the manufacturer or as universal parts built to the same specs. Control boards are the part most likely to be discontinued, and a universal board often fills in. What we won't do is patch a cracked heat exchanger, so that finding turns the talk toward replacement.
Who do we call about a gas smell at our Hanover house?
Leave the house first, then call your gas utility from outside. In Hanover that can be CenterPoint Energy or Xcel Energy depending on your street, so check a recent bill now and save the emergency number before winter. Once the utility has made things safe, we can repair the furnace or its gas valve.
