"Really appreciate the quality and reliability of One Hour Heating & A/C. Easy to schedule appointments, and their staff are professional and courteous. I use the services for my main home as well as a rental property. They provide recommendations on maintenance and improvements, but never pushy about it. Highly recommend this team!"

"After the AC stopped running I sent a service request to One Hour Heating & AC (Modern Mechanical) on Sunday night and they had a tech out the very next morning. Scott came to check on the system and very quickly diagnosed the issue. He was an absolute pro! He clearly explained what the problem was, told me what to watch for in the future, and was able to get my system up and running smoothly again in about an hour. Service like this is why I have been using one Hour/Modern Mech since they replaced my systems 10+ years ago. Thanks Shawn & Scott!"

"I was concerned after reading some people’s reviews and also gave peace of mind from other people’s reviews. My experience with Jaime Valenzuela was very pleasant. He explained all the details out and answered any questions I had. He was professional and resolved my issue. Thank you."
