We called today because our air conditioner upstairs stop working three days ago. We called our service company and they said we could use a third party contractor. I called Cowboys heating of air of San Antonio and the customer serice representative was very helpful in explaing the different programs they had available. We chose the yearly maintenance program for 179.00 and 50.00 for the additional unit. Danny the contractor came out with a big smile on his face . We was very friendly and knowledgeable about the unit and explained what was missing and how we could repair it for us. We were completely satisfied that we fixed our air conditioner within an hour. thank you Danny and Cowboys.
