“I would give this company 10 stars if I could! Came home from work on a Saturday night to a warm house and was able to schedule an emergency technician to come out on Easter Sunday! After ordering some parts, a well qualified and friendly tech, Shaheem, was able to get everything working for less than I originally expected. The office and management teams are both efficient and happy to help. So happy I called them!”

“One Hour HVAC installed the Mini Split for our patio a while ago. If you want one of those, call them immediately! We were so impressed, we fired our other HVAC provider for the maintenance program. Mario from One Hour HVAC arrived on time today for our first maintenance. I'll try to keep it short, but Mario did a very thorough job with all of my HVAC units. He even made a couple of recommendations that I am grateful to be aware of now. I have forgotten how much I paid because of the value I have received. Joe”

“Mario is a HUGE asset to One Hour AC/Heating. He was so knowledgeable and attentive. He gives top notch white glove service, which is becomming increasingly rare nowadays. He made sure to put booties on his shoes so he facilitates a no mess workspace. I need to effusively praise him for his work ethic and attitude. Plesee recognize Mario so he feels seen, so that he continues to provide above and beyond service to all your customers. It makes such a differnnce when they care. All my best, Kaz O'Conor. Feel free to call me with any follow up. Thanks.”
