ask this old house installs a solar attic fan
It was not until a friend of mine Attila, an instructor at the East Los Angeles Skills Center stressed the importance of proper attic ventilation that I began realizing how important solar attic fans are in terms of energy efficiency. He highlighted many times our homes remain hotter because of the hot air trapped in the attic which can make your air conditioner run longer per day.
Attila has been in the heating & cooling business for over 30 years and understands well the mechanics of how to keep a home cool. We all understand solar panels are very reliable, since they have no moving parts they can last over 25 years. The fans on a solar attic fan are similar to what you would see on a traditional attic fan and sometimes even better if the solar attic fan has a brushless motor.
Since solar attic fans do not need a source of power, building permits are not required to install one, since you would not have to bring up a high voltage DC cable up to your roof top. I wonder why so many people are skeptical about the value of a solar attic fan? I think This Old House did a fantastic job educating viewers about solar attic fans, wouldn’t you agree?
