Furnace Burning Smell in a Minneapolis Home: What Each Smell Means
Dust, hot plastic, rotten eggs or exhaust: what each furnace smell means, which mean shut it off now, and the basement causes we find in Minneapolis homes.

In Minneapolis, a furnace replacement runs $4,500–$9,500 installed with us: roughly $4,500–$6,000 for an 80% furnace and $6,500–$9,500 for a 96–98% model. In the city's older houses, venting drives much of the job, because a PVC-vented furnace can leave the water heater alone in the chimney. The city's mechanical permit is included.
Replacing a furnace in a pre-1940 Minneapolis house is mostly a venting and ductwork job. A 96–98% condensing furnace sends its exhaust out a side wall in PVC, and on a narrow city lot that wall may face the neighbor's house a few feet away, so the termination has to meet the manufacturer's clearances from windows, doors and the lot line. The gas water heater left in the old chimney often needs a liner or a power-vent model. Staying with an 80% furnace in the chimney works if the flue is sound.
Converted gravity ducts move air well, but the returns are often undersized or oddly placed, and old duct wrap can contain asbestos, so it gets tested before anyone cuts. Furnaces that replaced gravity systems were often oversized; a Manual J commonly calls for less. CenterPoint Energy supplies the gas and offers heating system rebates on qualifying high-efficiency furnaces and boilers. The City of Minneapolis requires a mechanical permit and inspection, and we pull it.

An installed furnace from us runs about $4,500–$9,500 in Minneapolis: 80% AFUE roughly $4,500–$6,000, 96–98% AFUE roughly $6,500–$9,500. Same prices in Minneapolis as in every town we serve. See the furnace replacement cost guide. For what drives a quote locally, see HVAC cost in Minneapolis.
In Minneapolis, CenterPoint Energy handles gas-side rebates for high-efficiency furnaces, boilers and thermostats, and it lets you pick your own heating dealer, provided the application is filed in the calendar year of the install. Heat pump, AC and ductless rebates come from Xcel Energy, and some of those need an Xcel-registered contractor, so ask before you sign. The City of Minneapolis also runs Green Cost Share rebates for owners of one- to four-unit homes through the Center for Energy and Environment; check its rules before work begins. Rebate programs change every year, so check the utility's current terms before you buy.

Usually not. Radiators give even, quiet heat, and switching to a furnace means running ductwork through plaster walls in a house built without it. A new boiler keeps the radiators and most of the piping. National cost guides such as HomeGuide put a gas boiler replacement at $4,000–$9,000. If you also want cooling, ductless heads or a high-velocity small-duct system can add it without full-size ducts.
Probably. Furnaces that replaced gravity systems were often sized generously, and since then most of these houses have gained insulation, storm windows or new windows. A Manual J load calculation measures the heat loss of the house as it stands today, and in a story-and-a-half bungalow it commonly lands well below the old nameplate. A right-sized furnace runs longer, quieter cycles and stops overheating the rooms closest to the basement.
