What Size Furnace Do I Need for a Minnesota House?
Furnace size comes from a Manual J heat loss at a -15°F design day, not square feet. Input vs output BTU, AFUE, why old furnaces run big and what to ask for.

Edina holds the 1924 Country Club District, one of Minnesota's first planned neighborhoods, and the streetcar-era bungalows of Morningside, surrounded by postwar ramblers and a steady run of teardown rebuilds.
We repair and replace furnaces, air conditioners, heat pumps, boilers and ductless mini-splits in Edina and across Hennepin County. Every visit starts with a $79 trip charge and a written price before any work, and the $79 is waived when you go ahead with the repair.

Book in EdinaEdina's oldest houses are in its northeast corner. Morningside was platted in 1905 on the old Grimes farm and orchard, and several hundred houses, many of them bungalows, went up there by about 1936; it was a separate village from 1920 until it rejoined Edina in 1966. The Country Club District, platted in 1924, filled with Tudors and Colonial Revival houses by 1941. Most of these homes started on coal-fired gravity air or hot water, and today many pair a modern furnace with the original large ducts or keep a boiler and add cooling separately.
After the war, Edina spread south and west with ramblers and split-levels, and with larger custom homes on bigger lots in neighborhoods such as Parkwood Knolls and Rolling Green. The houses now replacing many postwar homes are built to current energy code, with tight walls, mechanical ventilation and often a second system for the upper floor. One Edina street can hold a 1920s house on its original ductwork beside a new build with zoned heat.
Edina's older houses hold heat poorly by modern standards. Many Country Club District and Morningside homes were built with little or no wall insulation, so even a correctly sized furnace runs long in a cold snap. Plaster walls and old windows also mean humidity has to stay modest in winter, or frost forms on the glass and moisture works into the walls. In the rebuilt houses, the typical calls are PVC vents drifted over and condensate lines frozen where they leave the house.
Upper floors in Edina's Tudors and bungalows sit under steep roofs with small ducts or none, and by late afternoon they're the hottest rooms in the older neighborhoods. Minnehaha Creek runs through northern Edina, and houses near it can carry basement humidity through the summer. On the rebuilt lots, two condensers often sit side by side along a narrow side yard; spacing them so they don't feed each other hot air helps both last.
Edina homes buy gas from CenterPoint Energy and electricity from Xcel Energy. CenterPoint's heating rebates cover high-efficiency boilers as well as furnaces, useful for older houses that still heat with hot water, and you can use the dealer of your choice. Xcel's heat pump rebates, including cold-climate mini-splits for upstairs rooms without ducts, work through its Trade Partner Network, so ask whether the rebate needs a registered contractor. Minnesota's HEAR and HOMES rebates haven't launched.
Rebate programs change every year; check the utility's current terms before you buy. Our guides: Xcel and CenterPoint rebates, heat pump rebates, what happened to the federal credits.

Yes, with planning. Start with the published sound rating of the outdoor unit, since variable-speed models spend most of their time running slower and quieter. Then choose the spot: away from a neighbor's bedroom window, on a solid pad, with the line set routed to suit the placement rather than the shortest run. On close lots we walk the location with you before install day.
As two separate systems. Each furnace needs a fall check and each air conditioner a spring check, with filters changed and condensate drains kept clear on both. A furnace or AC tune-up starts at $129, and a combined furnace and AC visit is $219 per system. Maintenance plans are available on request if you would rather have both systems on a schedule. Also make sure the two thermostats are not fighting each other on spring and fall days, one heating while the other cools.
Most doesn't. Edina requires a certificate of appropriateness for demolition, new houses and significant changes to street-facing facades, while interior work and in-kind replacements don't need one. A furnace swap is interior work, and keeping condensers and vents off the street-facing side avoids most questions. If a vent, line set or outdoor unit has to change the front of the house, check with the city's heritage preservation staff first.
Early, before the framing plans are final. Ask for a room-by-room Manual J and a duct design, leave a mechanical room big enough to service the equipment, and plan chases for ducts to the upper floor instead of squeezing them in later. Decide on zoning or two systems, and pick condenser spots away from the neighbors' windows on a narrow lot. A new, tight house also needs balanced mechanical ventilation.
