“We were told by another company that we needed a new thermostat and were given a quote that seemed very high. We decided to call One Hour Heating and Air Conditioning for a second opinion, and they were able to come out the very next business day. Matt thoroughly reviewed our HVAC system and quickly determined that there was nothing wrong with the thermostat at all—just a disconnected wire. He reconnected it, and our system has been working perfectly ever since. We truly appreciate Matt’s honesty, professionalism, and expertise. Thank you to Matt and the entire One Hour Heating and Air Conditioning team. You will definitely be our first call next time!”

“Shawn and Patrick on the plumbing side, and Matt and Tim on the HVAC side have all been to our home. Each of these experienced technicians has been exceptional. All have been professional and respectful, and fully communicated to us everything we needed to know. I am confident that anyone Ben Franklin sends us will be capable of diagnosing and completing the work we need.”
