The Solar Guys put a solar attic fan in 2 years ago. Not sure if there are actual savings but figured moving a little air up there couldn’t hurt. The installation went well. I asked them about garage door insulation and since we only get sun in the early morning they said it would be a waste. They also have a garage fan but it just dumps the air into the attic. If it went out the roof I would consider having it installed but for now I am not doing anything.
