Project Parsons WV Lab HVAC replacement

General Information

1.0 Scope of Work

Furnish all labor, materials, equipment, and other incidentals to replace existing cooling system with high efficiency natural gas HVAC split system.

2.0 Background

The AC split system to be replaced was installed in 2005, current unit is comprised of a 5-ton outdoor condenser and indoor air handler with appropriately sized evaporator coil and is capable of cooling only (outdoor condenser, indoor air handler) a natural gas hydronic boiler is used to provide winter heating, with a hot water coil in the AH. Due to the age of the boiler, and that this unit comprises one complete heating loop, installing this unit will allow closing off this loop, and utilizing a more energy efficient means of heating and cooling this area of the building, in turn, extending boiler life cycle, as well as saving money.
