We received an advertisement for a special on air duct cleaning @ $5.99 a vent. After adding up our vents and taking into consideration any additional fees not disclosed, as well as the "fine print", we figured out the cost to be $150-$200. When their service technician showed up for our scheduled appointment, he looked in 2 vents and then quoted me a price of $822, stating that I need to read the fine print which states there could be additional fees. This was completely out of the ballpark of previous quotes we received and not even close to the company's advertised price. After I clearly stated my shock and disappointment to the tech, he told me he could "call his manager to see what he could do". I explained to him that his price was so far out of the average that it wasn't necessary to call his manager. He continued to do this back and forth shady salesman type of behavior with calling his manager several times. I told him I wasn't interested and asked him to leave. He then said "well you know there is a cancellation fee". This was not disclosed anywhere in the ad and I advised him of this. He then told me "well there is mention of a travel fee in the ad". I had not signed or agreed to anything. I told him I would not pay any fee and his response was "really...you're not going to compensate me for my time or travel? I came all the way from Mesa." I refused. I continued to become more frustrated and asked him again to leave. He continued to try to sell me on "partial services" to reduce the cost. Literally, I was ready to call the cops to make this man get out of my house. Still after about 20 more mins taking his time getting the few things he brought in for equipment out of my house, he finally left. This company is a complete joke. Do not use their services. They are so shady. I will make sure I warn everyone that I know about this company.
