I went through dishonest companies, one guy even left his bar bell weight on my roof because he didn't want to pay to dispose of it, they weigh a lot. Another guy said he was an expert when he had his cousin working for him who was "an Allan Block expert", but was really an unemployed plumber. I contacted the Better Business Bureau, and he threatened to sue me, and the list goes on. I was completely relieved when I was told about "360 Comfort systems" and haven't looked back. They are truly on the customers side, they are very honest and caring. Thank you, "360 Comfort Systems" and have a Very Merry Christmas and New Year. Victoria
