A great balance of value and performance. 

WaterFurnace 3 Series® units benefit from technology that’s been refined through 30 years of research, engineering advancements, and manufacturing experience—all at a great price point.

The dual capacity 300A11 offers efficiencies reaching 22.3 EER for cooling and 4.1 COP for heating in closed loop conditions (27.3 EER and 4.5 COP for open loop). These ratings are significantly greater than any ordinary conditioning system. Our Aurora communicating controls work in unison with system components to provide simple setup, troubleshooting, and diagnosis for the contractor, in addition to providing confidence and peace of mind for you.

All 3 Series units are ENERGY STAR® rated and were engineered in the HVAC industry’s only in-house EPA/ENERGY STAR Recognized Laboratory. Best of all, 3 Series units use the stored energy in your yard to provide savings of up to 70% on heating, cooling, and hot water.

The Symphony system, by WaterFurnace, is a complete system monitoring package that internet enables the entire unit, giving you access to all the data you need, where ever you need it, to not only control, but monitor and troubleshoot your WaterFurnace. Symphony is cloud-based, so there’s no software to install and provides control over your entire geothermal system - not just the thermostat as in other ‘smart thermostat’ systems.
