“Chase was very professional. He was able to troubleshoot and determine that a part had failed. He had the replacement part in his van and was able to change out in a few minutes. Explained what he did and got our system up and running and it started to cool down the house. Chase was very knowledgeable and so easy to talk with and carry on a conversation. Glad he helped us out.”

I think it also needs mention that the young lady who takes my appointment is also very friendly, extremely courteous and accommodating, as well as patient and understanding. I honestly can’t imagine ever going with another company for my HVAC needs”

“Hunter did a great job and pointed out an issue I was unaware of that was producing mold. They had the solution to fix the mold and we will soon have clean air running throughout our system…”

“The service agreement I have with Joe East that calls for 2 visits a year is some of the best money I spend each year. The technicians catch a lot of issues before they become a catastrophic problem and are normally able to give me a heads up when it's time to replace a unit before it goes out. I've been a customer for 25 years now.”

“I was very impressed with the quality service that this company provided today. They helped us out quickly and I glad I called right away due to wiring burned out on compressor it would of never gotten any cooler in my home. I was very happy Trice showed me this issue and had it fix very quickly. Thanks again.”

“I called to have my AC unit checked before the weather really heats up. Jeff and Kalani came out the same day and provided a full system diagnostic. They arrived on time, spent over an hour inspecting the system thoroughly, and even helped me reprogram my thermostat. Great service all around—thank you, One Hour Heating & Air Conditioning of Orange!”

“Corey is a personable person to deal with and I would recommend him across the board! He was very proficient in his work and explained things to me as well as answering any questions that I may have asked! I will most likely request him when it's time to check my furnace! He has a good personality for this kind of work with people!”
