FIVE STARS!!! GREAT SERVICE!! Saturday evening, my heater quit working. It was just blowing cold air. I called precision air and their technician arrived about an hour later! I was so happy with the quick service. He showed me in his book what it was going to cost me and asked me if I wanted him to fix it for me right then! I was so surprised that he could fix it on a Saturday night. He didn't even charge me anything extra for after hours. He fixed it, and gave me the bill. It was exactly what he said it would be, which was much less than I thought it would be. My heater is working and great, and my family is warm. Thanks so much!
