“One Hour HVAC is always perfect. They arrive on time and send a text with the technician's picture. I always have Austin. He is such a nice man. He always describes everything he is doing. I use their twice a year maintenance - spring and fall. I have just today used their duct cleaning service. I have been there for 5 years and I do not think it was ever done! I am so happy to have clean ducts AND the dryer vent was very very clogged. Austin did a great job on that too. He is very careful to not leave any mess which is very important to me. I recommend them !!! I wish I could leave them 6 stars.”

“John was beyond wonderful. He walked through and explained everything in a way that encouraged me to understand not just accept what he said blindly. Very respectful to do so. Kind, patient, and better than on time actually early. A rarity for my region, professionalism at its finest. Thank you John. Kyle was informative, to the point, and informative. Kyle detailed cost breakdown and gave me an estimate immediately confirmed with timely email follow up. Very professional.”
