He took the time to explain everything clearly, making sure I understood each step of the process. His professionalism and attention to detail were evident, and I truly appreciated how informative and thorough he was. Spencer went above and beyond to ensure I felt comfortable and confident in the work being done. It’s rare to find someone so knowledgeable and genuinely committed to excellent customer service. I highly recommend Spencer for anyone needing trustworthy, top-quality HVAC support.”

“Yesterday, the issue was diagnosed. AC unit needed to be replaced. The team came this morning to install the new unit (inside and outside) and again, they were all very professional, did a great job. Very friendly technicians. They explained the difference between the new unit and the old and shared advice on how to best operate the AC. I highly recommend the service of this company! And my house is called again😃”

“I actually had One Hour do some work last year and they were out again this year. I really appreciate the fact I can call these guys and they'll show up the same day. That really helps, especially in this Texas heat. I had the same technician, Brent, nearly exactly a year later. He's patient, answers any questions I have, gives me tips on how to maintain the system and got me back up and running. I'll keep coming back here for my HVAC needs because I can depend on them. Im giving the 5 star specifically for Brent. I appreciate the business model and always getting there in a timely manner, their costs are just higher than most others.”
