Ventilation Direct's HVAC unit achieves an impressive 21.3 IEER rating (Integrated Energy Efficiency Ratio) which is over 1.5x the ASHRAE 90.1-2016 IEER standard. Designed with the future in mind, Ventilation Direct's HVAC unit is poised to exceed rising IEER standards for years to come.

Ventilation Direct's HVAC unit contains fully modulating refrigeration and optional hot gas reheat components that deliver the exact amount of air requested at the desired temperature and humidity. Variable speed components allow the unit to adjust its heating and cooling capacity to match the required load. This provides a consistent temperature throughout the space and avoids large temperature swings often associated with single stage equipment.
