This guy walks into my home, feels the top of my dryer that had been running all morning, says "it's hot" so my dryer duct cleaning wouldn't be covered by a Groupon because it's clogged. It was not hot at all, and he didn't even look at the duct. He also said that because my A/C vents were dirty, that the previous owners had never had the dryer vent cleaned. Warning: If your A/C vent has a hint of dust, he will not honor the Groupon. I don't know how this company is still in business. This was the worst experience with a company that i've ever had, and am very disappointed that my time was wasted. THIS COMPANY IS A SCAM! Do yourself a favor, go somewhere else.
*UPDATE* I had another company come out and actually look at my dryer vent (unlike Mr. Duct) and it was not even close to clogged. The company I hired after Isaac also took pictures and showed me the unclogged vent. Once again, Mr. Duct is an utter scam.
