The Dormer vent whole home attic cooling fan system is capable of a high air flow volume from home interior windows, door screen or sliding door screen doors through attic spaces to significantly cool home interior, attic spaces. Cool attic spaces reduce roofing temperatures that extend roofing integrity. On most hot days, the whole house fans are sufficient to cool home rather than use of air conditioner. Al & Ivan Whitworth have promptly replied to our concerns and promptly scheduled system

Installed Whole House Fan. With vaulted ceilings, house became hot and stuffy during those "no wind" humid days. Turn on the fan and sucks all the trapped hot air out and fresh air in. We like that the windows can be kept open and bring in the "natural" air from the outside. Would highly recommend. After years of having the system in place, one of the remotes started acting funky because of a battery leak. Called Al and ordered a replacement. Went to pick it up at his shop and he called

As usual, a quick response to my request. Ivan is someone you can depend on and feel confident in his follow through.
