The guys at House Fan Pros ROCK!!! I had two other companies come and give me a quote before they worked their magic. The first company wanted to charge me 1k more and the 2nd said there was no way they could install the unit. House Fan Pros came in and spent the time researching my home/attic looking on how and where would be the perfect spot. Fast and clean workmanship. My upstairs temp reads 80 and in 10 mins it’s drop like 5 degrees once I turn it on. Love my fan and these guys are fire!!!
