On a late Saturday afternoon I notice that my AC drain pipe was clogged. Water had started to leak on the floor. So, I called Environment Masters for service. I thought I would have to wait until Monday to have this issue resolve. But I was wrong, they sent out a plumber name Daniel that same day. He was very professional and took care of the problem in under an hour. Out of all the AC companies that I have used in the past. Environment Masters has been the best AC company to use!! Exemplary customer service that can't be beat!!!
