I used them today to come clean my dryer vent and duct. They pulled the old "bait and switch" and my $39 bill suddenly was going to become a $300 bill. the contract stipulated 1 vent cleaned for $39 on the dryer. The Guy who came out refused to clean the 1 vent saying it was too cold for him to go outside. and proceeded to tell me it was his choice which vent he cleaned. Since I had already cleaned the interior vent myself there was only 1 vent left The two guys that came out tracked water, snow and dirt all over my house. He broke a clothes hanger I had downstairs, and he said i had mold in my heat pump without even opening it. . When I called their main office the lady fought with me like I was asking for something ureasonable and told me she didn't have time for me today then hung up. I highly recommend you NEVER use this company. You will be grossly dissapointed. I have also filed a complaint with the BBB just to be sure they are aware of the horrible customer service .
