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!

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!

When is it time to replace that air conditioner or furnace?

Certain telltale signs indicate it's time to consider replacing heating and cooling equipment, or improving the performance of your overall system. Extreme’s One Hour Heating and air conditioning recommends considering replacing if:

Your heat pump or air conditioner is more than 10 years old.

Consider replacing it with a unit that has earned the ENERGY STAR label. Installed correctly, these high-efficiency units can save up to 20 percent on heating and cooling costs. Return on investment can be as quick as 3-5 years.

Your furnace or boiler is more than 15 years old.

Consider replacing with an ENERGY STAR qualified furnace, which is 15% more efficient than a conventional furnace. If you have a boiler, consider replacing with an ENERGY STAR qualified boiler that is 5% more efficient than a new, standard model.

Your equipment needs frequent repairs and your energy bills are going up.

Your cooling or heating equipment may have become less efficient. All electronics in a furnace or air conditioner are prone to fail. If your system needs frequent repairs now is the time to replace.

Some rooms in your home are too hot or too cold.

Improper equipment operation, duct problems or inadequate insulation could be the cause. In the Dayton, Beavercreek and Springboro areas we see this problem the most. This can be prevented with a proper engineering analysis that Extreme’s One Hour Heating & Air Conditioning provides at no charge.
