I tried 6 local air conditioning companies to figure our why the first floor of the house was getting much more air than the second floor. 5 Star was the only company that went into the attic and figured out that the original installer didn't place dampers on some of the trunks.

Thanks so much, I have and will continue to recommend them. read more
