    "We are really glad we got these fans installed. I have seen a big difference on the top floor when it's hot out. My husband has been on the roof a couple of times and the installation is solid. I really recommend this company and the fans."

    Due to lack of industry standards, CFM is often quoted as the maximum peak output of a bare fan in laboratory conditions. iSolar CFM is representative of operating in typical attic conditions ranging in output from 250 CFM to a maximum of 400 CFM, depending on intensity of the sunlight and duration of direct sunlight on the panel.

    Happy Customers

    iSolar Attic Fan is the Way to Go!
    “We installed 2 fans on our home and have enjoyed a dramatic temperature drop on our second floor. It’s nice to be able to sleep at night with the windows open. The units really make a difference on hotter days as we have been able to set our A/C at 75F and it hardly ever comes on! Without a doubt we saved significant dollars on our electric bill. Love this product!”

    Donna L.

    Cooled Us Off

    “We installed one and we really noticed the difference in these last couple of days as our house was really cool when we came in from work without the AC turned on. I am thinking I may install one on the cottage.”
