I should have done this awhile back, years ago. Last 10 years we kept putting in larger air conditions and it struggled to keep our brick house cool at all, When I was looking thru the ebay site it mention something in passing about keeping your house cooler without adding to our enormous electric bill. I thought what could it hurt, I'll give it a try. I see them on our local school buildings, they must work??? So after installing just one, let's see if it helps. Summer is here and I'll tell you what a great product, it kept the house cooler by seven degree's and the light bill actually went down, Let's not forget the air conditioner was now operating within normal use, actually cooling the house down during the afternoon and surprisingly having to shut it down at night. I 'am going to install one more, because these brick houses are hot in the summer and cold in the winter!Read full review

The Turbines (5) were installed by the Roofing Co. and the turbines all wobbble and and are of Very Light material. They are difficult to balance and the wind does not turn all the turbines the way they should. The Roofing Co. will Replace all Five ( 5 ) in the spring, as they will be covered for the winter. They highly recommended Whirlybird Turbine, which I agreed to have them come back in the spring when the covers are taken off and replace them. I will not be able to return them as they are installed and sealed with the Plastic tar material. They will make an adjustment on the new ones on the price in 2019. Thank you.......Fred

Have used this product for many years on multiple homes. Well made, reasonable pricing always, and product lasts! Product makes BIG difference in keeping home cool in summer, keeps rain/snow out, keeps attic moisture down or non existent, very quiet operation. And it also uses no electric power to boot! What's not to like?

I am impressed with how much longer it stays cool from morning through most of the afternoon having the turbine vent and a solar powered vent keeping the attic zone heat buildup in check. I look forward to next summer to feel the results on the really warm days.
