We offer professional maintenance and repair services to keep your heating and cooling system running efficiently.

How HVAC Filters Work

The primary function of HVAC filters is to prevent debris from getting into the internal components of your heating and cooling equipment. However, they do play a role in the indoor air quality of your home. Any particles that make it through an air filter may travel through your HVAC unit and continue on via ducts that lead to the vents in each room of your home. In an effort to improve indoor air quality, manufacturers produce several styles of filters, such as fiberglass, pleated, and electrostatic types.

Airborne Particles

Airborne particles can enter your home through openings around windows and doors. If you have a particularly drafty house, there may be a high level of pollutants traveling through your HVAC system and clogging your filters. The experts at North Point Air Conditioning & Heating can perform an evaluation to locate areas where the air is entering your home.

Unseasonably Warm or Cold Temperatures

Did you know that the weather affects the efficiency of your heating and cooling system? If it is unseasonably warm or cold outside, your HVAC equipment works harder to keep your home comfortable. The equipment runs more often, and this increases the volume of air going through your filters. During these peak use times, it is normal for filters to need changing more often and usually does not indicate a HVAC issue.

Damaged Ducts

Heated and cooled air is moved through your home in a series of metal tunnels. The tunnels have junctions that are held together with hardware and sometimes sealed with tape. Over time, the connections or the sealing tape may come loose, and dirt and debris may enter the ductwork system through the openings in areas like the attic. These particles get recirculated through your system, and your HVAC filters end up getting clogged and need to be changed. It is recommended that you have your ductwork professionally cleaned every two years. This will not only increase the quality of the air in your home but also reduce the frequency of air filters needing to be changed out.

High-Quality Filters

High-quality filters cost more, but they may be necessary if a family member has respiratory issues. They filter more of the particulates out of the air in your home and may reduce symptoms associated with allergies or asthma. Because they catch a larger volume of debris and smaller particles than lower-quality filters, they may need to be changed more often than low-quality filters. This is normal and probably does not indicate a problem with your HVAC system.

Types of Filters for HVAC Systems

HEPA filters are the most effective style and trap more than 99% of airborne particulates, including viruses, pet dander, and mold spores. They are commonly used in hospitals. For homeowners who have family members with respiratory issues, this may be a good option. Fiberglass filters are typically the style of choice for budget-conscious homeowners. The downside is that these filters do not trap small particulates. Some pleated filters can be reused, which makes them another preferred choice for frugal homeowners. Electrostatic filters may be best for reducing allergies.
