I found this company via Groupon which I now realize was my first mistake. Went through an extensive documentation process (I think my new car purchases required fewer forms) to set up an appointment for Dryer Vent Cleaning. Date and time were confirmed via email. I got the laundry room ready, pulled out the dryer (its almost built in), took time off work (for this and other errands). Waited. Called - was promised that someone would show up. They didn't. Company then would not answer calls later in the day. I read elsewhere that they had cancelled many window cleaning appointments in May due to weather. In the past I have had other companies that needed to show up late or change appt dates. It's inconvenient but sometimes things happen. But they always called or sent an email or did something to reschedule. Despicable company. Takes your money ahead of time and then doesn't perform the work. Won't respond.
Company finally said that they 'attended my house' but no one answered. I told them I was home and I have security cameras. They then said they went to the wrong house!
If they can't find a large house with an address (and they also have a picture of the house!) then how can they find the lint in your dryer.
Trust me, not worth the hassle. Won't refund money. Had to go to credit card company to get the charge reversed.
