My property has 2 furnaces installed by Extreme. Both are heat pump with natural gas backup. Both furnaces (one 4 years old, one just installed) were done promptly and are what we expected. I would gladly endorse and recommend Extreme.

We are simply delighted with the new high efficient system we had installed by Extreme’s One Hour, but we were blown away by the amount of money we saved! The rebates and credits are great but the tax match made our decision to choose One Hour an easy one. Thanks One Hour!

Very pleased with the service provided by Extreme. I’ve been recommending you to co-workers and friends. I also submitted an "A" rating on Angies List, to help future customers choose Extreme Heating and Cooling.

After getting multiple estimates to replace my air conditioning system One Hour Heating had the best product for the best price thanks to their tax match program and did a fantastic job of installing my new system.

Wow, Extreme’s One Hour Heating and Air are true experts in their field. My family and I had suffered from uneven, uncomfortable temperature throughout our entire home for years. Not only did One Hour fix this issue completely while installing my new system, I saved a small fortune. With the tax match program, rebates and discounts from One Hour I saved over $3,500.00!

Bringing jobs to Springboro

“Springboro has always been one of my favorite parts of the Miami Valley and we are fortunate to have a large client base located here” Says Doug Washburn, General Manager of One Hour. “We’re currently looking to open a second sales/ service office in Springboro. Our Company needs to be well equipped to handle the growing demand of business in this area.” Currently, everything is operating out of our Beavercreek location. “With our on-time guarantees, it’s becoming more and more apparent that we need a second office for our technicians to operate out of” says Washburn.

Once we have established a location our company should be able to provide 4-6 new jobs. Our new location will have immediate openings for office staff and a couple new technicians.
