AC Maintenance Tip: Make Sure to Regularly Change Your HVAC Filters

As an AC maintenance tip, experts recommend changing your HVAC filters regularly. Many factors affect how often you should change your air filters. Generally, manufacturers recommend doing it every 90 days. It is one of the most important things you can do to maintain your HVAC system. Why is that so? How much can the cleanliness of air filters affect the performance of the whole HVAC system? Here are the answers:

  1. Maintaining Air Quality in Your Living Space

Your HVAC system works by retaining airborne contaminants in the filter and releasing clean air into your room. These contaminants, however, will stay and accumulate in the filter.

At some point, the built-up contaminants will get blown out along with the air and enter your living space. This means your indoor air will not be as clean as it used to be. The longer you delay changing your filter, the more contaminants will pollute your indoor air.

Airborne contaminants include pet dander, dust, pollen, bacteria, and even many kinds of allergens. If inhaled, they may cause many respiratory and allergy problems. Even if you have no health issues like asthma or allergies, inhaling bad-quality air will eventually harm your respiratory system in the long run.

  1. Lower the Energy Cost

Filters that are clogged up with dirt may restrict the airflow. That makes your HVAC system use extra energy to meet the indoor load requirement. Extra energy means a higher electricity bill for you at the end of the month.

Some people refuse to replace their HVAC filters regularly because they think it costs too much. Little do they know that neglecting their dirty air filter silently costs them even more.

Running your HVAC system with clean filters is proven effective to cut back on energy consumption by up to 15%. Make sure you change your air filters regularly to see how much you can save on utility costs.

  1. Reducing Stress on Your HVAC System

Dirty filters force an HVAC system to work harder. This may lead to overheating. Keep this going, and your whole HVAC system could be damaged. Some parts may break sooner than expected. Therefore, you will have to spend extra money on repairs, or even replacement.

If you want your machine to last long, you need to reduce the stress on it. Clean filters allow your machine to run smoothly and gently. That is why you need to change them regularly.

  1. Fewer Emissions for a Reduced Impact on the Environment

Another bad result of dirty HVAC filters is carbon emission. When the machine is dirty and overheated, it will emit more greenhouse gases and leave a larger carbon footprint on the environment.

We can’t simply ignore the alarming issue of climate change. Every little action matters, including changing your HVAC air filter regularly.


The quality of air filters is crucial for the overall performance of your HVAC system. Failing to keep them in a good, clean state may eventually create problems in your home and in the environment.
