If you are dissatisfied with the service, they might offer a refund. I was dissatisfied with the service Carpet Dry Tech offered. I specifically asked the owner of the company (who answered the phone, a nice touch) if the process would remove residue on the carpet. He assured me it would, and I was able to make an appointment for the same day. I asked the technician to tell me the ingredients in the spot cleaner. Since he couldn't tell me what was in the spot cleaner, I asked him not to use it. Next thing I know, he's spraying on the spot cleaner. If you check out their website, it says they use agitation/extraction. Translation: they spray on a citrus cleaner (that I had to open the windows because it started to give me a headache), then the technician pushes around a machine with a fabric pad attached to it around your carpet. I was left with carpets that had more residue on them. How did I know? The carpets were soft before the technician started, then when the carpet dried, the carpet fibers felt unpleasant to the hand and foot. Yes, I did try to address this with the owner of the company. He would not even partially refund my money. He said it was ""immaterial"" that the tech didn't listen to my concerns. I ended up spending another $154 to get another company to fix the problem and steam clean my carpets.
