WaterFurnace Geothermal Heat Pumps

WaterFurnace Geothermal Heat Pumps


WaterFurnace systems are designed for high-efficiency heating and cooling at your home or business. Powered by geothermal energy, nearly all WaterFurnace products meet or exceed the ENERGY STAR® requirements, delivering earth-friendly comfort you can feel great about.

What is Geothermal Energy?

Geothermal energy is heat from within the earth. This energy is accumulated from solar heat hitting the ground, the natural decay of materials in the soil, and the eternal burning of the planet’s core. Just a few feet below the surface, temperatures average between 50º-70º year-round thanks to geothermal processes—no matter the season.

How WaterFurnace Technology Works

WaterFurnace technology harnesses geothermal energy to provide efficient cooling and heating for homes and commercial spaces. Using a series of underground pipes called an ‘earth loop’, the WaterFurnace system draws from the underground reservoir of energy, concentrates it, and then transfers it into your home in the form of warm or cool air.
This technology can also be used to generate heat for your water heater tank. This optional upgrade can generate up to 50% of your hot water at a fraction of the cost. For higher volumes of hot water it may be ideal to install a dedicated hydronic unit.

About WaterFurnace Systems

WaterFurnace systems come in three basic configurations plus a fourth ‘combo’ type suitable for countless applications.

All-in-One Systems

These systems offer year-round comfort. They are built to provide heat in the winter and cooling comfort in the summer. All-in-One WaterFurnace ground source heat pumps can replace both traditional indoor furnace and outdoor air conditioning equipment with a single unit.

Hydronic Geothermal Systems

Water-based hydronic geothermal systems are useful for applications like radiant floor heating, domestic hot water, and melting snow or ice. They are often used to replace boilers and can also provide forced heating and cooling when installed with an air handler.

Split Geothermal Systems

A split geothermal system is ideal for applications that call for installation flexibility. These can be installed with a remote air handler for whole-house heating and cooling. The ‘splits’ in this type of system allow geothermal technology to be used in conjunction with a fossil fuel heating system in colder climates.

Combo Systems

While all-in-one forced air is typically the most cost-effective, many people prefer the luxurious warmth of radiant hydronic heat. Combination units allow property owners to get the best of both worlds, providing both soothing radiant heat and forced air—all from the same unit.

Crowther's HVAC did a total install for an older house for me 14 years ago. They are very good at what they do and are also the epitome of customer service. Any problems that I have had they took care of immediately at very reasonable prices. Add in that they are all really good people and you have the formula for a very successful business. Rereccomend them highly."

Harry Haynie

I selected Crowther to replace both of my HVAC systems and they did a great job. They went the extra mile to correct duct work, and add a vent in order to bring my homes HVAC systems up to the best performance.

Blake Auchmoody

We had a total duel system heat pump replacement. It was a pleasure working with CHAC. From the sales rep to the technicians responsible for the install. Very professional in their craftsmanship and ensuring everything was installed and working correctly. Very courteous and respectful of our property. We are new to the area and am glad we chose CHAC for our HVAC needs.

Steve Casey

For 25 years, Crowther has provided excellent customer service and support for our Carrier zoned heat pump. They are responsive, helpful and great to work with! We love their seasonal maintenance program and have had them complete some system redesign for our home renovation. All around a great team!
