"My experience with Dun One Hour Heating & Cooling was great! The technician contacted me earlier to inform me that he would be arriving in about 20 minutes. I explained to him what was going on with my air conditioner unit on the phone. He arrived at my home on time and completed the job in a timely and efficient manner. He explained the problem to me in a way that helped me understand it more clearly. He was friendly, knowledgeable, and professional. I was very satisfied with his work. I will recommend One Hour Heating & Cooling to my family and friends! Jackie😃 August 26, 2024"

"I've been struggling to get someone to my house for 4 days to look at the fan blade at my house. The team at 1 hour heating was able to rearrange their technicians to get someone out to my house within 30 minutes. Rob was fantastic, he was friendly, knowledgeable and honestly made me feel a whole lot better about the entire situation with my air conditioner. I'm really thankful for the entire team for getting somebody out to assist me and I will absolutely be utilizing you in the future."

"I have been with Dunns One Hour for 14 years. This repair was same day as Robert had the part on the truck when he arrived. They are always prompt and fair with skilled technicians. I trust what they tell me and know I am getting honest service from them. I have confidence in this great company!"
