"Our technician came to the house very late at 9:45 pm on Saturday night. This was amazing! It was 90 degrees in our living room with 5 fans running. We are over 80 years old and both of us have heart issues. We were suffering. He repaired it and we had a good night's sleep."
"When my AC decided to call it quits at the worst possible moment, I called them last minute and not only did they squeeze me into their already packed schedule, but the technician showed up at my door at 9 PM. He rolled up his sleeves and got my AC back up and running."
"Our technician went above and beyond for me today. Great price — around $300-400. He came and repaired our A/C. He did an excellent job. We highly recommend On Time Heat & Air."
