“Two Words - THE BEST!! Brian, Jansen and Kevin are amazing!!! I had an over 20 year old ac unit that needed the boot and they came over, gave me and estimate and we started work the next day! There were a number of unforeseen issues but Kevin and Jansen went to work!! When I say work, they worked… They stayed later when needed. They weren’t on their phones, Taking lots of breaks, etc… They were locked in on getting our AC unit up and running for us. I truly would recommend these guys for all your AC needs. Jansen is knowledgeable and takes the time to explain everything!! There are no stupid questions with him! I would recommend them 1000 times over!!”

“Jansen is very knowledgeable, when he opened up the thermostat that blanked out. He already noticed a problem, he & Kevin proceeded to do some tests and was also to figure out the issue. A new thermostat was installed & my air conditioner is working again. They are both very nice guys, very friendly & easy to work with.Their price is reasonable! I will use them again next time.”

“Seriously awesome experience with One Hour Heating & Air. Super easy to work with, super nice team, and everything came out way better than I expected. They showed up on time, kept me in the loop the whole way, and didn’t try to upsell me on a bunch of stuff I didn’t need. Honestly, just solid people doing great work. Would 100% call them again.”
