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!”

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.”
