City staff discovered a clogged HVAC drain and poorly functioning floor drain in the mechanical room of Fire Station 2 at 1301 Wilson Pike.  This particular mechanical room is very small for the large amount of equipment located inside, including HVAC air handlers, cabinets, plumbing, and a water heater.  The floor drain was located underneath the water heater stand and was relatively inaccessible. The accumulation of moisture in the mechanical room damaged surrounding drywall and caused mold to grow both outside and inside of the wall.  Because one of the mechanical room walls adjoins occupied spaces of the fire station, quick remediation of the mold problem was imperative.  This required the removal of the water heater and HVAC air handlers, as well as cabinets and duct work.  
   
The HVAC equipment being removed had reached the end of its useful life.  This, together with the need to eliminate the mechanical overcrowding that allowed the moisture problem to go unnoticed, necessitated replacement of the two split HVAC units with five-ton package units that sit outside of the mechanical room.  Placement outside of the room also means that moisture lines for the units will no longer be piped to the floor drains.  This work required relocation of the back-flow preventer and other plumbing within the room. 

Oversight for the scope and pricing of the project was provided by City's maintenance technician from Cushman & Wakefield.  Interstate A/C Service was contracted to remove the old units and install the new units and duct work.  Interstate A/C is a Nashville-based HVAC contractor who has provided excellent service to the City on previous projects. The total installed price for the units was $26,247.00.
