2 Reasons Your HVAC Technician Cares if You Change Your Air Filters


One of the most important comfort accessories you can maintain is your HVAC’s air filter. Here are two reasons your HVAC technician wants you to keep this in mind.

With so many comfort accessories to use in your home or with your heating and cooling system, it can be difficult to decide which ones to focus on. But one of the easiest things the average home or business owner can pay attention to is the air filters in his or her HVAC system. But why are air filters so important? Here are at least major two reasons.

Reason #1: Maintaining Indoor Air Quality

Unless you have a separate air filtration device or appliance in your living or working area, the primary method for cleaning your indoor air will be the air filter in your HVAC system. There are typically at least two air filters to help clean the air.

One air filter is in the HVAC unit itself, often in the air handler. If there are more air filters, they will usually be in the air intake vents or registers. Each of these air filters exist to remove particles floating from the air that can not only cause respiratory problems in people and pets, but also potentially damage the moving parts in your HVAC system.

The older the air filter is, the less able it can remove particles from the air. One of the reasons for this is that less air is able to flow through a dirty air filter. With less air flowing, there is less of an opportunity for the air filter to remove particles from the air. The only way around this is to clean or replace your HVAC’s air filters.

Reason #2: Lower Your HVAC’s Energy Usage

Besides being less able to remove air contaminants from the indoor air, an old and dirty air filter reduces the energy efficiency of your HVAC system. This is because for a given amount of energy usage, less air can flow through the ductwork when there are dirty filters. Therefore, with air moving less freely, the HVAC system will use more energy to maintain the normal amount of air flow. If this doesn’t occur, the user will usually try to compensate for lower performance by setting the heater to a higher temperature or air conditioner to a lower temperature. Either way, the HVAC uses more energy with dirty air filters than clean ones.
