My air conditioning unit stopped producing cool air today, which in the Texas summer can be a serious issue. I called Comfort Experts in the early afternoon, expecting to be told that no one would be available until at least tomorrow if not later. They had a technician to my house to evaluate the situation within 2 hours! He was very polite and knowledgeable, and told me exactly what was wrong with my system. I was surprised to learn that this relative new (about 5 years old) system had grounded itself and was basically non-repairable. However, he said it was still covered under warranty and did everything necessary to arrange to get a new one for my home as soon as possible. I was very impressed and pleased with the level of service and caring that was exhibited by both the lady who made the appointment for me on the phone, as well as the technician himself. I highly recommend.
