Save $1,000s on your cooling bills

Your basement is a free AC – use it to cool your home

What is Cool Down?

The Cool Down system sends the naturally cool temperatures from your basement into your living space. At the same time, the system draws heat from your living space and sends it to your basement. The excess heat from your home is dispersed into the ground through your basement keeping your home cool during the hot summer months, while saving you money on your electricity bills.

Don't worry!

Basement air doesn’t have to be sent to your living space.

A Cool Down system can include an optional heat exchanger, which exchanges temperature, but no actual air between your basement and living space.

Frequently Asked Questions

  • The Cool Down system uses your basement as a natural heat sink. The Cool Down system moves warm temperature from your living space into your basement using your return duct. At the same time a heat exchanger (which we install as part of the system), exchanges cool temperatures with the basement, moving that cool temperature into your living space, and cooling off your home. For more information, please review our blog post here.

  • The Cool Down system is the most efficient way to cool your home without using AC condensers or heat pumps. Our system uses the naturally cold temperature of your basement as a source of cooling for your home. On top of that, Cool Down has a much lower upfront install price, starting at just $5,000. In addition, Cool Down’s operating costs are considerably less than that of a traditional cooling system. For more information on how Cool Down compares to other systems check out our blog post here.

  • Of course! Our patented technology uses a heat exchanger to move cool basement temperatures in your living space. This means no actual basement air is being moved upstairs, only the cool temperature. For more information on how this works, please review this blog post here.
