From the time I spoke with Diane to paying the bill with DJ, it was a very pleasant experience. We were not in a hurry, as we have two systems and we were having a problem with our secondary unit. But two gentlemen, Barron & Kevin came in around 4:30 that afternoon and were extremely polite and courteous. Both systems thoroughly checked out and cleaned. All parts needing replacement were shown to us along with an explanation as to what was wrong and what the part did. It was hot outside, but not once did I feel they were in a hurry and were very thorough in their work. Thank you to the One Hour Heating & Air Conditioning team. Great job!
