Air Filter Service
After this past New England winter we are all very glad that Spring is finally here! While it is great to have the warmer weather one thing that some people struggle with during this time of the year is the start of allergy season. As the temperatures start to rise, trees and flowers are starting to bloom and with that is an increase in pollen. These airborne particles will enter a building through open doors and windows and they can cause people with allergies to suffer.
One line of defense to help reduce allergens in the building is changing the air filters in the HVAC units on a regular basis. This is one of the most basic tasks in performing maintenance on an HVAC unit. The air filter plays an important role in keeping the air we breathe clear of contaminants and keeping the equipment and duct work clean. Just look at the attached picture of the dirty pleated filter that was in a unit for only three months compared to the clean filter beside it. If the filter did not catch all of those particles then they would have gone through the HVAC equipment, into the duct work and into the air employees are breathing. Not trapping these particles in the filter would lead to costly cleaning bills of the facility and the duct work and vents. The poorer air quality could also lead to more people being sick and missing time from work which would reduce overall company production.
Often times people try to save money by buying cheap throw away filters which only catch a minimal amount of air born particles that were trapped by the filter in this picture. Using a quality pleated filter and changing it at a proper interval will improve the overall air quality in the building and prevent the evaporator coil and duct work from getting dirty. A dirty evaporator coil will cause a unit to work harder and thus run longer useing more energy. Also since the unit is running longer and working harder the motors and other components will break down sooner and that will result in downtime and costly repairs.
Filters receive a Minimum Efficiency Reporting Value score (MERV rating) and the higher this number the better job the filter will do capturing air particles. The benefits you will see from using a high quality pleated filter over a cheaper filter include:
- Improved air quality for the employees.
- Increased efficiency of your system by keeping the evaporator coil, blowers and duct-work cleaner.
- Reduced repair costs as the equipment is not working harder or longer than is necessary.
- Lower janitorial costs by reducing the amount of dust in the building.
It’s well worth spending the extra $3-4 per air filter when you consider the above benefits you receive. The cost of frequent filter changes is far cost-effective than the increases in energy usage and potential repairs due to increased wear and tear on your equipment. You could also extend the useful life of the very expensive HVAC equipment that is handling the comfort cooling for your building. One last point is that this is a very inexpensive way to reduce our overall impact on the environment.
MMI only uses quality pleated filters so our customer’s equipment continues to run at peak efficiency.
