ESi Decades Series Heat Pump

Smart, Quiet, and Affordable

The ESi variable speed inverter heat pump is one of the industry’s most innovative and efficient systems, with ratings up to 18 SEER2 and 8.5 HSPF2. With Ecoer’s patented technology, the 18 SEER2 heat pump automatically adjusts itself while maintaining constant and consistent speeds to avoid temperature swings.

Rigorously tested for long-lasting durability, you can be sure this system will hold up against inclement weather or extreme conditions. This unit provides comfort, while running quietly (as low as 56dB–that’s a whisper).

Compared with fixed speed systems, Ecoer inverters have a much wider capacity range which helps achieve faster heating and cooling. With more than 30 variable stage settings, Ecoer inverters provide more accurate and efficient temperature control while using less energy.

Energy Savings: Save up to an estimated 50% in energy costs with this unit. Estimated energy savings up to 50% based on our rated matched system. The majority of systems installed prior to 2006 are 10 SEER or lower. Potential energy savings may vary depending on your lifestyle, system settings, equipment maintenance, local climate, home construction and installation of equipment and duct system.

System efficiency is measured in SEER, (Seasonal Energy Efficiency Ratio) and HSPF (Heating Seasonal Performance Factor). The higher the SEER and HSPF, the greater the system’s energy efficiency, and the lower the overall carbon footprint of your household.
