Air filters for commercial HVAC systems will need to be periodically changed to maintain optimal indoor air quality. If filter changes aren’t on your to-do list, you could be seeing higher heating and cooling costs or creating an unsafe environment for employees and customers. Here are some essential tips to keep in mind when it comes to HVAC filters.
Change Filters On Constantly Used Systems
HVAC systems in commercial environments often work harder than similar systems in a home. Because of this, filters should be checked, at least, once a month and changed just as often. Filters need to be checked even more frequently if your commercial environment includes a lot of industrial operations, an HVAC system that’s in constant use, or indoor areas where there’s likely to be dust and debris on a regular basis.
Know When Filters Should Be Changed Immediately
Air filters on HVAC systems are designed to efficiently keep air that circulates indoors free of impurities. It’s not possible to do this job if a filter is torn or damaged in some way. Other reasons to immediately replace an air filter include visible evidence of microbial growth or mold directly on the filter or within its fibers. If you are using an HVAC system in a commercial setting where there’s a lot of moisture in the air, check filters regularly to see if they are damp. Wet or damp filers should be changed immediately to prevent mold growth.
Take the Right Steps When Changing an HVAC Air Filter
Before replacing a filter, the unit should be turned off. After taking out the old filter, use a dust cloth to get rid of any dirt that might be around where the other filter was in place. Replace any gaskets, levers, or seals that had to be removed. Check to be sure there is no significant space around the filter. After the replacement filter has been secured, turn the unit back on and observe it while in operation to confirm that the filter is firmly in place. Finally, write down the date when the filter was changed to make it easier to know when it’s time for the next change.
Changing HVAC air filters is often a do-it-yourself job. Just make sure you purchase filters for the model you use to heat and cool your business areas. During filter changes, look for signs of excessively dirty or clogged coils and other performance issues that may be making your system worker harder then it has to, even with a new filter.
