Why Manitoba attics need this
Manitoba gets both extremes hard, and the attic catches every one. Winnipeg and Brandon summers run 25°C to 30°C (78°F to 86°F) with humidity rolling north off the Great Plains. Attic probes in Winnipeg homes regularly read 52°C to 56°C (125°F to 132°F) by mid-afternoon in July. That heat radiates straight down through the ceiling into upper-floor bedrooms, and AC fights it through the worst of summer. Severe prairie thunderstorms break the heat for an hour, then the sun goes right back to cooking the shingles.
Winter is where Manitoba writes its own chapter. Winnipeg sits in one of the coldest winter climates of any major North American city, with multiple weeks below -25°C every year. Damp warm attic air condenses on cold sheathing, ice damming forms along the eaves, and asphalt shingles installed in Charleswood or River Heights often need replacement at 15 to 18 years instead of 25 because of the seasonal swing.
A solar attic fan handles both jobs on one piece of equipment. It moves humid summer heat out and it pulls winter moisture out before it can freeze on the deck.
What we install
One 30W solar attic fan with the panel built into the housing, UV-stabilized for prairie summer sun. The installer mounts it on the back slope where it stays hidden from the street, cuts a clean opening, flashes it for wind-driven snow, runs a thermostat and a humidistat, and ties it off with extra attention to ice and snow uplift. Professional install in a single visit. No electrician, no new circuit, no operating cost added to your bill.
What you'll save
The average Manitoba home uses about 14,000 kWh per year because hydroelectric power covers most of the heating load. A typical summer power bill in Winnipeg sits near $130 in July. Owners who install a solar attic fan usually see a 10 to 18 percent drop in summer cooling cost (per U.S. Department of Energy residential cooling-load guidance). The longer-game payoff in Manitoba is the winter side. A dry attic means insulation that keeps working through six months of cold and fewer ice dam claims, which run $4,000 to $10,000 in Winnipeg.

Installed by Manitoba authorized installers
Winnipeg building stock leans on 1900s to 1920s character homes in Wolseley, Crescentwood, and St. Boniface, postwar bungalows across St. Vital and East Kildonan, and 1980s to 2000s splits in Charleswood, St. James, and Sage Creek. Brandon adds prairie farm-town stock. Most older Winnipeg homes have minimal soffit ventilation by modern standards. Back-slope mounting keeps the unit invisible from the street. You pick a date, the installer shows up, and your attic stops cooking in summer and stops sweating in winter.
