“I received excellent service from 1hr. Heating and air. I spent exactly what I was quoted for a/c repair. The technician was respectful of certain special circumstances I have at home due to a special needs child. “So come on summer” thanks to 1 hr. My family and I are ready for ya! Thank you”

“(This is my husband's old voice mail. It should say "Roland"). Dillon Sorensen was friendly, professional, thorough and went above and beyond to help me and to explain everything in a way I could understand. He also outlined choices and alternatives explaining pros and cons. Francesco, the technician, also went above and beyond to sort out what was wrong with my heating/cooling system and give me a good idea of the condition of the system and its function and what was probably needed both temporarily and long term and probable outcome depending on my decisions. I was very favorably impressed with both of the! and would highly recommend your company. Btw, Congratulations on your Founders Day Anniversary! Kirby installed our a/c unit and did a great job, being professional and friendly. He made sure to explain to me how to use the system and encouraged me to call them right away if I had any questions. He and his team worked within the time frame promised and were clean and careful. I had a very positive experience. Thank you.”

“Today is Sunday, my parents AC is broken. Called One Hour Heating and Air Conditioning Service, spoken to Jordan and couple of hours later it’s all fixed and working and the price was right to my parents surprise since they are both retired and don’t have much! Jordan, this young generation was very sincere, professional and knowledgeable. We are very grateful for the service he provided and wish him well. Thank you 🙏🏻”

By Sunday morning I had a new A/C unit installed by KT and Jimmy, both were very professional, polite, and knowledgeable if I could I would give the entire team 10 stars. Thanks to everyone involved from start to finish very satisfied with the end result!”

“Mr. Clexton was extremely helpful. He listened to my concerns about the air conditioning unit and informed me what he thought every single step of the way. However, the communication between the company and myself could be improved. They still are sending messages to the incorrect number and not myself.”
