The intent of this Request for Prequalification is to pre-qualify contractors to provide Heating, Refrigeration and Air Conditioning (“HVAC”) Services to all City departments. Much of the City’s HVAC systems are antiquated and in need of repair and replacement. About 75% of all City’s HVAC equipment is the original equipment that has passed its intended life expectancy by many years. The City is in dire need of replacing many systems such as chillers, boilers, roof top package units, IT server room units, split systems, pumps, motors and some piping needs. The City has many chillers that are over twenty-five (25) years old. The City has original HVAC controls (over 30 years old) for some of the most critical buildings, such as City Hall, School Administration Building and many others. Parts for these control systems are often difficult to find.
