Iowa has the fifth-oldest population in the country — 17% of the state is 65 or older — and the housing stock reflects that. In the river cities (Dubuque, Davenport, Burlington, Clinton, Keokuk) the dominant home is the 1890s-1910s Queen Anne or Italianate with 8-to-10-inch riser staircases, walnut newel posts, and ornate balusters you cannot drill without specialty bits. In the interior cities (Des Moines, Cedar Rapids, Waterloo, Sioux City) the dominant homes are 1940s-1960s Cape Cods and ranches with shorter steeper flights. The Driftless Area of northeast Iowa (Allamakee, Clayton, Winneshiek counties) has hillside farmhouses with exterior entry steps from the gravel drive to the porch — outdoor lifts are a weekly job in that region.
The second factor is Iowa's weather. The August 10, 2020 derecho produced widespread 100-140 mph straight-line winds across central and eastern Iowa and knocked out residential power for up to 14 days in some Cedar Rapids and Marshalltown neighborhoods. Winter ice storms regularly produce 48-72 hour outages. Our Iowa fleet ships every install with 72-hour extended-backup battery capacity standard — not a 24-hour default. Iowa families have seen multi-day outages three times in five years.
The third factor is the farmhouse reality. Rural Iowa homes — across all 99 counties — often sit on gravel township roads with power lines strung from single-phase distribution. Voltage sag during weather events is common, and off-the-shelf stairlift chargers are sensitive to it. We install a surge-and-brownout-rated charge module on every rural Iowa job at no upcharge. The city installs in Des Moines and Cedar Rapids get the standard module because grid voltage is more stable.
Built for the Iowa climate
Iowa's climate stressors are brutal: summer derechos and winter polar vortex. The August 2020 derecho left parts of Cedar Rapids without residential power for up to 14 days. Winter lows routinely hit -20°F across the state and the 2019 polar vortex put parts of northern Iowa (Mason City, Decorah, Estherville) below -30°F. Our Iowa fleet ships three standing upgrades: cold-weather-rated LiFePO4 batteries certified to -20°F on every install, extended 72-hour backup capacity as standard, and a surge-and-brownout-rated charge module on every rural install. The 72-hour backup is not marketing — Iowa families have lived through three multi-day outages in the past five years.
