I call Grays Heating and Air Conditioning whenever I have a problem, and they come out that same day and take care of it. You can't get better than that! The last time I used them was not too long ago when my air conditioning unit was not functioning properly. They came out and quickly resolved the problem. I have known Grays for twenty-seven years, and I've dealt with their owner and technicians. They are all courteous and efficient. I am very happy with their service and will continue to use them in the future.
