These fans are the best! I compared and researched first, then consulted with the Remington tech people before I bought. (Thank you Remington). My attic has never been cooler, and it made my new HVAC system more efficient as well. My house is 1400sf with a 5:12 pitched shingle roof, and I bought two of these fans. During my re-roof, I placed each one 1/4 of the distance from each end of the roof, and just below the ridge. They of course must coincide with passive vents – so I put 3 O’Hagin vents on each side of the ridge (6 total). The air flow is amazing and means that on many days I won’t have to use the AC at all to keep the house cool, so that’s another savings. I bought one accessory kit from Remington to connect them to house wiring and a wall switch, so I can use them after sundown on days when it’s still hot after dark. After 35 years in this old house, finally a real solution to removing attic heat, and it costs nothing to run.
