Carlos did very well explaining what we needed. Even showed us his certifications! He also repaired our unit when other companies said "not repairable."Took him a few minutes. But we still wanted to purchase a new system( ours is 40 yrs old) simply because they are more efficient. Pam P.

Called on Friday afternoon and they had a tech at my home by Saturday morning. The service technician Daniel was extremely professional & knowledgeable. Daniel patiently discussed my repair needs and offered cost effective options.

I cannot say enough amazing things about these guys! Jayden and Nic have been 5 stars across the board, from the initial installation to every maintenance visit since. We genuinely look forward to seeing them every time they come out.They are the true definition of professionalism. Their knowledge and technical skills are outstanding, and they always present themselves with courtesy and respect. What impresses us most is the patience they have in taking the time to explain everything and making sure we fully understand how to operate and manage our system before they leave.Its rare to find technicians who are not only experts at what they do but also genuinely care that their customers feel confident and informed. Jayden and Nic consistently go above and beyond, and we couldnt recommend them more highly. They are an incredible asset to the company! (And the bunnies like them)

Carlos provided exceptional service during his visit to our home. He took the time to thoroughly explain how our A/C unit works, what maintenance it needs, and what we can do to improve the quality of the air in our home. His knowledge and expertise were evident, and with over 20 years of experience, it was clear we were in great hands. Carlos was professional, patient, and genuinely kind throughout the entire appointment. I highly recommend Carlos and One Hour Heating & Air to anyone looking for honest, knowledgeable, and outstanding HVAC service!
