Minnesota's housing is built around cold weather and a staircase type most other states don't have: the 1960s-70s split-level, which dominates Bloomington, Burnsville, Edina, Richfield, Eden Prairie, Minnetonka, and Roseville. A split-level has a short half-flight from the front door to a mid-landing, then another half-flight to the main living level, and a third short flight to the bedrooms. Standard rails handle each section individually, but the mid-landing swivel geometry needs to be pre-configured before the truck arrives or you waste an hour on-site.
The Duluth, Iron Range, and North Shore story is different. Houses in Duluth, Hibbing, Virginia, Ely, and International Falls run 80-140 years old with steep stair geometry and basement-to-main-floor straight runs that frequently need narrow-gauge rails. Iron Range company housing built by US Steel and Oliver Mining between 1900 and 1940 has some of the tightest residential stair geometry in the Midwest. We measure over the phone before dispatch.
And then there's the cold. Minnesota's -30°F January nights kill standard stairlift batteries inside a single winter in Duluth, Bemidji, International Falls, and the entire Iron Range. Every install north of Highway 8 ships with a cold-pack battery rated to -30°F as a baseline spec, plus a battery blanket for any lift installed in a garage, three-season porch, or unheated mudroom. Cold follow-up calls in March catch degradation before the claim hits.
Built for the Minnesota climate
Minnesota's climate is the harshest in the lower 48 for stairlift batteries. January lows of -30°F are routine in Duluth, Bemidji, International Falls, and the Iron Range, with -50°F windchill on the worst nights. Standard stairlift batteries fail in a single winter at those temperatures. Our Minnesota fleet ships cold-pack batteries rated to -30°F as a baseline spec on every install north of Highway 8, and for every install statewide if the lift is mounted in a garage or three-season porch. Summer humidity in the Twin Cities runs high enough to warrant sealed motor housings, which we include standard statewide.
