Called on them recently to install an attic fan as shape of house has lots of dead attic space which heat builds up. So I had attic fan put in to get temp down in attic. It has helped out alot. Also lenghtens the roof's life. They came out and installed pretty quickly. High pitched roof so I could not do myself with out risk of falling off roof. Also found a coupon to get $50 off which was great. Would call on again and tell a friend.
