“Jordan, Edward and Micca were fantastic throughout the entire process of my HVAC going out. They scheduled install of a new unit the next day. They even brought over a loner window unit to cool my house. While they made the repairs.”

“Zack was very pleasant and took the time to explain everything he was doing. He was able to show me where the issue was with my unit. I am apart of the membership program which I highly recommend. The company comes out 3x a year to check on your unit and keep it running smoothly. Thank you Zack for your service!”

“This company recently installed a new unit. This company's technicians took their time with the demo and replacement. Now I'm a member of their maintenance plan to ensure my AC is well kept.”

“Tom provided excellent service! He was polite and efficient while fixing our issue. I especially like that the company texts a photo of the service person and he called 45 minutes before arriving. I highly recommend One Hour!”

“The technicians Hunter and Mark were really nice and respectful! Very knowledgeable! Did good work and explained everything! The company owner, Justin stopped by to check on the work, and he was very nice, and respectful! If you are military or a veteran like myself, they take care of you! No hassles, very upfront and honest people.”

“David (if I remember correctly) was very helpful and provided a quote for repairs that was very affordable. I also appreciate the way he explained things that felt like a person to person conversation rather than a conversation with a salesman”

“We needed some ventilation ducting replace due to animals who got into house and chewed up old ducting. Our Project Manager did a great job of coordinating repairs and the installation team did the work quickly and well.”

“Once again, One Hour is excellent in executing their service contact. Josh did a great job of cleaning and servicing all three of my units. He further addressed any issues he found, and offered possible solutions to them. I really enjoy how thorough they are each time they come out.”
