My service company chose Cool Blew for our annual AC Tune up. My wife & I always have misgivings when we have to have ANYONE touch our AC due to the fact that every tech that comes has messed it up. But after our service from Cool Blew & specifically your technician Joseph (Joe) N., we will only allow Joe and Cool Blew to service our AC. Joe was understanding when I said I was staying up there with him. He showed me stuff I never knew about running the AC & it works better now than ever before!
