Maintenance Tips For Commercial HVAC Systems

By Greg Pierce

"Business proprietors can help guarantee the comfort and safety of your employees by maintaining your HVAC system correctly. We will discuss what every business proprietor should have the knowledge on requirements on maintaining most commercial HVAC systems.

The requirements for maintaining HVAC systems for commercial use are not the same as HVAC systems for residences. And what's more is, maintenance of commercial systems depends on the occupancy of the building. Factory occupancy is not the same as office occupancy. The generation of dust, for example, which is higher in some factories, will cause you to replace the filters more often.

Filters get replaced once or twice in a year even if homeowners are instructed to change them every month for residential use. Filters should be changed at the least four times in a year, that's once every 3 months in a commercial occupancy. In factories wherein chemicals are being used or there is a build-up of dust, the filters should be replaced more frequently than that.

The heat exchanger should be inspected as a routine especially if it is located externally, which is common in a commercial HVAC system. The heat exchanger would likely be cracked resulting in poor efficiency and effectiveness. This can start with just a hairline fracture, which may not be noticeable, but if the crack enlarges the problem becomes severe. So your HVAC system should be checked in a regular basis so that the situation could still be remedied.

The evaporator coils should be maintained once or twice annually. These parts are always damp, thus, they are prone to molds. And these are always exposed to elements causes them to corrode. Use a particular cleaning solution and skills so that the evaporator coils are free from molds and corrosion.

Make sure that the ventilation is sufficient. Facilities for commercial occupancy are usually designed for artificial ventilation. Redesign it for natural ventilation and lighting. You can cut costs not only from the HVAC but also from lighting.

The dampers should be cleaned always to ensure that there is adequate ventilation. Not functioning dampers not only affect the air exchange but also raise the consumption of energy. After cleaning, lubricate the moving parts properly for the best possible performance.

Your HVAC system should be inspected and serviced by professionals. A system that is properly maintained not only prevents diseases but also contributes to the comfort of the employees, which means they are always healthy and productive. - 42629
