One Hour Heating & Air Conditioning provides excellent service. Their technician, H. Nandlal, was prompt, professional, and very honest. He quickly identified the issue with my AC and did not exaggerate the problem or try to upsell unnecessary services. The repair was handled efficiently and in a timely manner. Because of the great experience, I decided to sign up for their monthly membership plan, which was very reasonably priced. I highly recommend their services to anyone in need of fast, reliable, and professional HVAC support.
My post is a couple of months late 😇 One hour heating was a life saver for me. My furnace stopped working on 1/30/26 after 9pm. I called 3 places One Hour Heating was the ONLY one that was willing to come out. It was one of the coldest nights and it was after 10pm by the time I called. The owner Dashon himself came out and got me up and running. I was so afraid that the fee just for coming was going to be astronomical but it wasn’t. The part for my furnace wasn’t available until the next morning but he got it running until the next day. Dennis came and put part on the next morning and they respected my request to come after 10am. 😆Both of them are very knowledgeable, friendly, patient, reliable and understanding.
I was thoroughly pleased with the Free Estimate I received from One Hour Heating & Air Conditioning. The techician arrived on time, was pleasant and very professional. I look forward to being serviced from One Hour Heating & Air Conditioning.
One Hour Heating and air conditioning provides great same day service. The technician Dennis provided exceptional services and didn’t stop working until my furnace produced heat. Dennis went above and beyond to ensure my furnace was functioning properly
