Fantastic Service Right When I Was in Need!




Online reviews and family recommendations led me to Extreme's One Hour Heating & Air Conditioning services. I'm very grateful that they did! The technician, Michael T., was outstanding. He was friendly, very knowledgeable, and explained everything in a manner in which I could understand. He was super-prompt, he did only what truly needed done, and explained ways for me to better maintain my own AC unit. He also suggested I consider having my units serviced from time to time due to their age, but recommended I wait until there was a special going on. He also was very friendly with my incredibly hyper dog, who was very happy to jump all over him. To me, that all speaks to top-notch service. I know now that the only call I need to make if I'm having trouble with heating & air is to Extreme's One Hour Heating & Air Conditioning. Thanks again, Michael!
