Subject: Nashua Police Department HVAC Assessment
The Nashua Police Deparirnent is seeking ine professional services of SMRT to assess the HVAC system
and to assist NPD in identifying the scope of our current HVAC project and expand on the information we
know as listed below:
j. In 2005 there was an NPD HVAC project, however due to budget constraints the HVAC
mechanical room equipment replacement was removed and is the originali977 system.
2. The main building's air handler for the a/e unit was condemned and never replaced. Currently
there is no method of cooling down the outside air entering curing the summer manihs, which
makes all the water source heat pumps wark much harder and causes break downs and costly
repairs. -
3. Additionally, there is a split AC unit on the 1“ and 2™ floor and one located in the basement level,
which use R22 refrigerant and this type of refrigerant is becoming obsolete. Over 50 waler source
pumps will need io be replaced.
4, Further analysis on air circulation is needed.
SMRT Architects and Engineers of Andover, MA was the engineering firrn contracted in 2005 and the
Nashua Police Department again recommends contracting services in the amount of $19,600. Funds are
available in the City Buildings Trust Fund TF29.7078.
