Stannah's outdoor stairlift is the 320, and it's made for straight flights. Stannah says it works in outdoor temperatures from 14°F to 105°F, and it carries riders up to 300 lb. Outdoor Stannah lifts begin at $6,300, and new ones include a lifetime gearbox warranty. The big checks are simple: do your winters stay within that range, and does the rider stay under the limit?

Will 14°F Stand Up to Your Winters?
It depends on your state. Drawing on NOAA records from 1991 to 2020, this table gives a feel for typical January overnight lows and July afternoon peaks across whole states.
| State | January overnight low | July afternoon peak |
|---|---|---|
| Maine | 6°F | 77°F |
| North Dakota | 1°F | 82°F |
| Minnesota | 1°F | 80°F |
| Virginia | 26°F | 86°F |
| Washington | 26°F | 79°F |
| Georgia | 36°F | 91°F |
| Texas | 35°F | 95°F |
| Florida | 47°F | 92°F |
| Hawaii (Honolulu) | 67°F | 88°F |
| Arizona | 31°F | 95°F |
Average January nights in Minnesota, North Dakota, and Maine fall under the 320's 14°F rating. Only a handful of outdoor models are rated low enough for those states. For six straight steps in Minnesota, two models handle the cold: Bruno's Elite Outdoor and Harmar's Summit. Florida is milder, so all six straight models with a published rating cover both seasons there.

Stannah Outdoor Stairlift Price
Stannah's price guide shows outdoor lifts starting at $6,300. Across brands, a new outdoor lift for eight straight steps usually costs $4,810 to $10,500, including installation. The rail is the fixed track set along the steps, and the chair travels on it. Each step needs roughly a foot of rail, which is why longer flights cost more. For 20 steps, the spread is about $5,272 to $10,962.
Weather Protection for the Lift
Stannah offers a protective cover for rain, snow, dirt, and sun. Since it keeps the weather off the lift, it's worth putting on between rides.
The Stannah warranty gives lifetime gearbox coverage on new lifts. The gearbox is the gear set that changes motor power into travel along the rail.
Common Questions
What is the average cost of a stairlift?
Stannah puts the average stair lift at $8,000. A used straight model is about $1,500 to $4,500. For curved steps, expect about $9,500 to $16,000.
Stannah or Acorn: which stairlift brand is better?
The brands publish different numbers. The Stannah 320 carries 300 lb with a 14°F to 105°F rating. The Acorn 130 Outdoor is limited to 280 lb and publishes no temperature range, so cold-weather performance cannot be compared.
Can a wheelchair user ride an outdoor lift?
A stairlift means the rider must transfer out of the wheelchair onto the seat. A porch lift instead moves a whole platform, so the rider stays in the wheelchair, and it can carry as much as 750 lb. Covering seven steps, roughly 54 in of rise, runs about $12,000 to $18,000, and the Bruno VPL-3175 climbs as high as 75 in.
What if the rider weighs more than 300 lb?
Bruno's Elite Outdoor holds 400 lb, and several other models hold 350 lb. On long rails, some lifts carry less. The Harmar Summit drops to 250 lb once the rail passes 15 ft 9 in, roughly 15 steps; the AmeriGlide Outdoor Deluxe falls to 250 lb once the rail reaches 16 ft or more.
