“The entire team at One Hour Heating & Air Conditioning were fantastic. From our initial service call, to sales and installation. The process moved quickly and we never felt pressured one way or another. Our new AC and Furnace are working wonderfully. I also appreciated the texts notifying me of who would be arriving with a photo and fun fact. 5/5 🌟 would recommend and use again!”
