Commercial Preventive Maintenance Plans

Proper maintenance of your building’s heating, ventilation and air conditioning system will:

1. Lower utility costs (by as much as 42%)
2. Increase the service life of the equipment (reducing replacement costs)
3. Provide a greater level of comfort to the occupants resulting in:

• Greater sales per square foot for retailers

• Higher level of productivity for office environments

• Lower employee absentee rates

4. Demonstrates you are adhering to industry wide “standard of care”.
5. Reduce your risk of exposing the occupants to IAQ problems (which in turn helps reduce your exposure to potential IAQ litigation).
6. Minimize emergency and unplanned repair expenses.

What are the best practices being followed today, in the industry, by experienced and trained HVAC professionals?

1. Replace filters (every 1 to 6 months)
Filters capture dust, dirt and other airborne contaminants and prevent them from being
spread through-out the building. Keeping them clean also assures the air handling portion
of the system is operating at its peak. Dirty filters can decrease cooling and heating output of the system as well as increase energy used by the system. Depending on how the HVAC system is being used, the type of facility it is installed in ,etc. filters should be inspected monthly (at a minimum) and possibly replaced monthly as well. A good quality filter (a minimum of a MERV 8) should be installed at least quarterly in many systems (actual replacement time frames may vary depending on a number of factors).

2. Clean Evaporator and Condenser Coils (1 to 2 times per year)
Evaporator coils, during cooling season, are damp and wet, and provide an excellent
place for molds and bacteria to grow. If they are cleaned regularly then mold and
bacteria growth can be minimized. As an additional measure we would recommend
installing UV-C lamps, on the discharge side of the coil, to keep them clean and
prevent mold and bacteria growth all year round. Condenser coils are exposed to unfiltered outdoor air and can see considerable perform reductions due to dirt, leaves, grass, etc. which are sucked into them during normal operation. Keeping these coils clean helps keep the system efficiency at its maximum and improves the longevity of the system.

3. Inspect areas around air intakes (2 times a year)
These are places where water, mold, bacteria, and other airborne contaminants can
be drawn into the building. Its important to visually inspect and clean these areas if
necessary to insure proper indoor air quality all year long.

4. Clean and adjust dampers (Annually)
Improperly operating dampers can dramatically impact indoor air quality and
equipment operation. Its important these be checked for proper operation at least
once per year.

5. Inspect the fan wheel, bearings and fan motor belts (2 times per year)
Fan assemblies should be inspected and cleaned if necessary at least twice a year.
Improper airflow, as a result of dirty or improper rotation can result in increased
energy costs and poor occupant comfort. Belts also need to be inspected, tightened—
if necessary or changed to insure proper operation of the air delivery system.
