“I have had great luck with this company and have called them back several times. Recently, there was a hiccup with a quote I received which was not accurate. However, when I contacted the company they acknowledged their mistake and remedy the situation completely. In fact, they provided an additional service free of charge given the miscommunication. This service was over 1k in value. I was floored that management took steps that extreme to make things right and keep my business. Additionally, Riley and Evan completed that additional service in a fantastic fashion. They were friendly, professional, and expedient. Highly recommend these folks!”

“Shout-Out to Alex Santana – One Hour Heating and Air Conditioning I want to give a big thank you to Alex Santana from One Hour Heating and Air Conditioning. He came out to our home on 07/01/2025 to check our air conditioning and did a fantastic job. Alex took the time to clearly explain what the issue might be and walked us through the possible solutions. His attention to detail was outstanding, and we truly appreciate his professionalism, insight, and willingness to help. Thank you, Alex, for your excellent service!”

“Cam is an absolute legend! The guy is a AC savant ! It’s nice when you know you’re trusting a professional who is genuinely interested in the customer experience. I will be recommending not only 1 hour , but Cam w/ 1 hour to anyone I can . I cannot thank him enough, this is the only company I’ll use for my heating and AC . Ask for my dude Cam , he is thorough, considerate, and educated and is a true professional. A+++”

“Faster appointments than the other guys, even the original installer. OneHour technician diagnosed the issue, and rather than just making a potentially expensive repair, he recommended working with the original installer under warranty to save me money. I appreciate OneHour’s prompt appointments and honesty. The other company is scheduling 4 days out, but at least we’ll have a second opinion and potential savings.”
