Ian called us at 10:00 on a Tuesday morning, came right over, fixed two refrigerated a/c units, charged us $75.00 and was on his way about 2:00 in the afternoon. He came back a few days later with a new thermostat just like he said he would and presto changio our house is cool all over for an additional $80.00 in parts! He was highly professional and knowledgeable as well. Overall, fantastic service, and a fantastic price. I would undoubtably recommend him and Longhorn to any and all of my friends and acquaintances in the future. This is what 5-star service looks like!
