This was my 1st time using ATI Anderson & I was very impressed with the quality of service. I had an A/C issue that caused several rooms to be inundated with water but I couldn't turn off the A/C because we have a heat index today of 110. So I needed A/C service today and the first few local companies I called were not able to come out until Friday. I called ATI Anderson & they sent a technician to my home within the hour. Robert (the tech) was very nice & quickly diagnosed the A/C problem which turned out to be a clogged PVC drain pipe. He made the repair efficiently& without making a mess (which has happened with other HVAC repairs). He explained exactly what was wrong & what was needed to repair the problem. It didn't take him long to finish the repair. I was pleasantly surprised with the reasonable charge for the service. I will not hesitate to call ATI Anderson again with any HVAC issue.
