Maintenance Requirements Of Commercial Hvac Systems

As a business owner, properly maintaining your HVAC system will help ensure the safety and comfort of your employees

. Aris Parviz of Virginias Able Air-1, Inc. is an expert in what it takes to keep your commercial HVAC system running smoothly. Here, he talks about what every business owner should know about the maintenance requirements of most commercial HVAC systems.

Like the systems themselves, maintenance requirements for commercial HVAC systems are quite a bit different than those for residential ones. Furthermore, commercial system maintenance varies based on what takes place in a particular facility. An office environment, for example, has different maintenance needs than a manufacturing facility. Because the amount of dust in the air will be much greater in certain types of facilities, the filters must be changed more frequently.

Replace filters regularly. As a basis for comparison, most of our residential contracts involve changing the filters once or twice per year, with the understanding that the homeowners will change the filters monthly. In a commercial setting, we normally replace the filters at least four times a year; and facilities in which chemicals are used or where significant amounts of dust are present will require much more frequent filter changes.

Routinely check the heat exchanger in a commercial HVAC system. If the unit is outside (as is common with commercial systems), it is much more likely to crack. A cracked heat exchanger will reduce the systems efficiency and effectiveness. While a small crack may have only a small impact, the problem can quickly grow in severity. As the crack widens, the effects will become more and more pronounced. By having your system inspected regularly, you can ensure that a cracked heat exchanger will not go unnoticed and that appropriate corrective action will be taken before the problem becomes serious.

Clean the evaporator coils once or twice a year. Because they are constantly damp, evaporator coils can harbor mold. And constant exposure to outdoor air can cause the coils to degrade. A special cleaning solution and techniques are required in order to ensure that all microorganisms are removed from the evaporator coils without damaging the coils themselves.

Be sure that an adequate amount of fresh air is entering the space. Commercial facilities are generally more airtight than residential spaces, so adequate fresh air is important when outdoor temperatures are comfortable. Because commercial systems are much more expensive to run than residential ones (and generally used much more intensely), its essential to cut costs wherever possible. On a nice day, if air from the outdoors is flowing freely, the system wont need to work so hard.

Check and clean the dampers. In order to make sure that enough air is flowing into the space from outdoors, your HVAC contractor will need to thoroughly check and clean the dampers. Improperly functioning dampers can contribute to poor indoor air quality as well as increase the systems energy consumption. Once the dampers have been inspected, each moving part should be cleaned and lubricated to ensure optimal performance.

Have your commercial HVAC system regularly and professionally inspected and serviced. A well-maintained HVAC system helps maintain optimal indoor air quality and consistent, comfortable temperatures, translating to healthy, productive employees. Proper HVAC system maintenance will also help keep your utilities costs down by ensuring maximum efficiency and help you avoid expensive repairs and replacements.
