United Air Cleaners

This company was listed under A Deep Breath Air Duct Cleaners on Groupon and I purchased a coupon offer for $69.00. The technician called in the morning to confirm but was an hour and a half late. He had no voicemail connected on his phone so I was not able to reach him.  He showed up to my house and made himself at home walking directly into my kitchen and taking off his coat to place on the kitchen chair. It was a classic "bait and switch" sales gimmick.  He checked the furnace and recommended cleaning and when I refused to add the $250.00 service he became irate.  if his manner would have seemed more trustworhty I would have had him clean the furnace but overall he was such a creep i was uncomfortable having in my house. I wish I had used Angie's list instead.  I have scheduled a furnace cleaning with a more professional and reputable company and the charge is only $96.00. 
I believe this company to be a scam.  They advertise under A Deep Breath Air Duct Cleaning but their invoice lists a company called Professional Air Duct Cleaning Company and also United Air Cleaners.  Beware!
