They had a coupon for an A/C checkup, to include a coil cleaning, so I hired them for my mother's house. They came out and did the checkup and found no issues. But they did not clean the coil as expected. They did not even touch the water hose. I opened up the A/C and found it very dirty. I called and complained about the failure of their employee and was told that they would check into it. They never called back...obviously they do not care about their customers.
