Air-to-Air Heat Pumps for Cooling
Some heat pumps can be used as supplemental cooling systems in large spaces that require five tons or more of cooling capacity. These units are usually ducted systems with the units installed on roofs or concrete ground pads. Click here for more information on air-to-air heat pump incentives.
Variable-Frequency Drive (VFD) Systems
Variable-frequency drives (VFDs) are systems that modulate the electric motor speed for water loop systems through changes in frequency, allowing the heating or cooling system in a building to run more efficiently. These are offered as a retrofit measure installed on a current HVAC system.
