Ventacity Systems, Inc.

2828 SW Corbett Ave.
Ste. 119
Portland , Oregon 97201
Phone: 888-836-8458

People need fresh, clean air inside where they live and work. Ventacity produces dedicated outdoor air systems (DOAS) with heat recovery ventilation (HRV) – the most efficient way to keep a building, and the people in it, healthy and comfortable. Ventacity’s products enable HVAC engineers to design buildings that reduce energy use by 50% by separating ventilation from air conditioning and applying heat recovery technology along with heat pumps to a building. If fully deployed, commercial heat recovery systems could reduce US carbon dioxide emissions by 220 million metric tons each year. That’s the same global warming impact as removing 19% (49 million) of US passenger cars from the road.
