Solicitation DEPT OF DEFENSE is seeking a repair service for HVAC systems. This service is typically used for maintaining and improving the heating, ventilation, and air conditioning systems in buildings. The work includes removing temporary package units and replacing them with a DX package unit, as well as replacing the existing dedicated outdoor air system. Additionally, a new duct bank will be installed and the existing fence around the outdoor air system will be removed. The current system does not provide adequate temperature control in the dog kennel area, so specific temperature, humidity, and air change requirements are not being met.
