Knowledgeable Techs




Since my HVAC system was installed by Extreme One Hour Htg & AC, I have taken advantage of their spring and fall system checks, and just had my ducts cleaned out. Service has been prompt, professional and always pleasant. When I schedule a service call, I know it will be done correctly, and the cost is very reasonable.

Great Experience!




Mike and Caleb cleaned our ductwork. They were fast, professional, polite and did a great job. They even showed us before and after pictures of their work and showed us how we can further improve our indoor air quality. I highly recommend Extreme’s One Hour!

Great service for a very reasonable price!




Company was on-time, very thorough, and even went above and beyond to show us some problem areas with our vents that another company had missed when installing them. The guys were very kind and cleanly, and took the time to make sure they had done everything and left the place looking like it did when they arrived. Very pleased and would recommend to anyone needed heating, air-conditioning, or vent cleaning service!

Extreme's One Hour H&A/C Semi-Annual Service




Service was excellent. E-mail invoice leaves much to be desired. Way too small - microscopic type. Did not accurately portray signatures.


Friendly and professional





Great service with awesome price! !




Techs are very friendly, great service, extremely satisfied with the result! Most importantly, the price is very reasonable and affordable. Surely we will return once we are due for another service.


Very professional




Michael was very professional from the moment he arrived. His visit was done in a timely manner and he offered several bits of advice that I found to be extremely helpful.


Great service




Prompt and efficient.


Did a great job





Outstanding service as usual. That’s why I’ve been a customer for many years and expect to remain.




Corrected a problem that could save major dollars in the future as well as loss of service on a really hot day: I have a bedridden handicapped daughter which means service year round is essential. Thanks guys. Wayne Rosholt
