How Long Does a Furnace Replacement Take?
A straight furnace swap is usually done in one day. Venting changes, a chimney liner, gas line or duct work, and the permit inspection add time. What to expect.

Shorewood curls around the south side of Lake Minnetonka and Christmas Lake, and on many of its lake lots the original cottage or rambler has either grown an addition or been replaced by a much larger house.
We repair and replace furnaces, air conditioners, heat pumps, boilers and ductless mini-splits in Shorewood 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 ShorewoodShorewood incorporated in 1956 from what was left of Excelsior Township around the lake's south shore, and its housing shows a steady build-out rather than a single boom. Ramblers from the 1950s and 1960s sit on large wooded lots, often on their third furnace but still on original galvanized ductwork. The 1970s and 1980s brought split-levels and walkouts on the hillier ground, where the lower level opens to the yard or the lake through sliding doors.
The islands and lakeshore streets are their own category. Older lake homes on Enchanted, Shady and Spray islands and along the bays were often expanded in stages, so an addition may sit on a crawlspace beside a full basement, each with its own heating quirks. Newer lakeshore builds carry larger systems, often with an ERV for fresh air. Where old and new meet on the same street, the outdoor units range from brand new to decades old within a few lots, and so do the service needs.
The islands and bay-front lots take wind straight off the frozen lake, and walkout lower levels facing the water lose heat through wide glass doors. Crawlspace additions freeze first. Wooded lots add a different problem: snow and ice sliding off tall roofs onto condensers and heat pumps under the eaves, bending fins and burying units. The fix is placement, or a small roof over the unit. Long cold spells also expose old ducts in unheated garages or crawlspaces, which lose heat before it reaches the room.
Walkout lower levels facing Lake Minnetonka or Christmas Lake stay cool without much air conditioning, but they soak up humidity, and carpet and finished walls down there can smell musty by August. A dehumidifier ducted into the return handles it better than turning the AC colder. Heavy tree cover shades the houses on the wooded lots, yet it drops seeds, leaves and cottonwood fluff into condenser coils and keeps the ground damp around outdoor units.
Shorewood is on CenterPoint Energy gas and Xcel Energy electricity. For the many furnace-and-AC pairs from the 1970s and 1980s, CenterPoint's rebates cover a high-efficiency furnace installed by any dealer, and Xcel's cooling rebates cover the new air conditioner or heat pump; ask whether Xcel's rebate needs a registered contractor. CenterPoint also has a rebate for a ducted heat pump paired with a gas furnace, and Xcel's AC Rewards program pays an annual reward for letting it adjust an enrolled smart thermostat on peak days.
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.

Usually not. The furnace often has enough capacity; the addition just doesn't get its share of the air, because the supply run is long, undersized or passes through an unheated space, and there's no return to pull air back. We measure airflow at the registers and static pressure at the furnace. The fix is typically a new duct run, a return in the addition or a zone damper.
Yes. Homes on Enchanted, Shady and Spray Island are part of our Shorewood service area, with the same flat pricing as the mainland. Getting large equipment onto an island lot can take more planning, so for a furnace or condenser replacement we work out access and delivery ahead of time rather than arriving with a unit on the truck and hoping.
Move it or protect it. The best spot is out from under the eaves and away from the drip line, on a pad raised above typical snow depth. If it has to stay put, a small roof or deflector mounted high enough not to trap discharge air keeps sliding snow and ice off the fins. Heat pumps need extra care because they run all winter and drain defrost water onto the ground below.
Not usually all of it. Galvanized ducts from that era hold up for decades. What wears out is the sealing: taped joints dry out, and the return side is usually undersized. We check static pressure and look for leaks at the plenum and trunk seams. Sealing with mastic, adding return capacity and replacing any crushed or rusted runs costs far less than new ductwork and fixes most of the problems.
