Very Professional Service




Men were on time in the morning. Did a great job in installing our new furnace/AC system. They wore shoe covers so they wouldn't get floor dirty when they came in. They cleaned up very well after finishing the job. Highly recommended!!

Non stop hard workers




Great employees but I would never have this done again or recommend having this done to anyone. We worked and worked to.clean up all the dust on floors and furniture. Great guys but the results were extremely disappointing. Could not set on leather couch until after all the dust was removed and it was a lot. Never again would I have this done. Still the men worked very hard and are very nice people but I was not expecting such a mess

Shopped around and this was the best price and service by a long shot




Incredible service and the workforce was very knowledgeable and attentive. Secretary on the phone was very polite and answered every question clearly. Service technicians Cory and Steven we're on time, very professionable, and accommodated special request. Cleaned up my ducts with very minimum dust, which is a huge plus. Best price with excellent service, I will definitely use this service again.

Duct cleaning




Awesome job!!!


Friendly service techs!




The 2 guys that cleaned our ducts out were so good! They got right to work. Explained everything they were doing and worked fast. They were so friendly to my kids asking them about their day and answering their questions. After they were done they explained our oil furnace and how to switch to propane. Very helpful and knowledgeable. Great service techs!

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!

Michael was professional and prompt. He even came out on a holiday weekend.


Great service, polite and experienced technician





Quick response and good service!




Our AC went out, I called in the late morning and the service tech came in about an hour. He diagnosed the problem and fixed it. I decided to buy the service program because our unit is getting old. Very good existence!


Anthony is very friendly and competent




You have taken care of me reliably for years.


Great service and very prompt - Came within hours of my call




The ServiceTech. - Anthony - Was very professional and explained everything he did and why. I would rate him 5 stars plus.


Great Service




Quick response and technician (Mike Treadway) was very honest and quick at fixing the problem. Would highly recommend this company and technician.


Great mechanical knowledge and customer service




Extreme One Hour is our go-to company for A/C services because we haven't found anywhere near us with as good customer service with value. Michael, specifically, is our requested tech. He provides a lot of background knowledge that we wouldn't be aware of and we trust his recommendations and because he's straight forward about what's really needed. It's nice not feeling like a car salesman walked into our living room to sell us a bunch of things we don't need. I appreciate interesting that Extreme One Hour is truly looking out for our best interests.
