Regularly inspecting and changing the air filters in your home is one of the most significant parts of HVAC maintenance that prolongs the lifespan of your HVAC system. By doing so, you can keep your system running smoothly and efficiently. It is necessary for preventing dust, dirt, bacteria, allergens, and other contaminants from circulating within the atmosphere of your home. This process ensures the best indoor air quality for a healthy and comfortable living environment. Below are several signs that your air filters need to be changed.
These are critical signs that you need to change your filters.
Your Air Filters Are Packed With Dirt And Debris
One indicator that you need a new air filter is that your current one is dirty. Dirty filters are filled with dirt, dust, and other debris, which is an easy sign to notice. Setting a reminder to inspect your air filter at least once a month and change it every three months ensures that it is being checked and changed regularly. This helps avoid a dirty filter impacting your home’s HVAC system and indoor air quality.
Your Vents Are Also Dirty
Dirt, dust, and other pollutants can enter the system through your air vents when your air filter is blocked or unclean, causing dirt, dust, and other debris to build up around your air vents. As a result, if you see dirt on the air vents of your HVAC system, it’s time to change the air filter.
There Is A Spike In Your Utility Bills
Another sign indicating that it’s time to change your air filter is an increase in your monthly utility bill. Typically, when your air filter is dirty or clogged, your HVAC has to work harder to regulate your home’s temperature. Hence, it consumes more energy, resulting in a higher energy bill. If you’re noticing an unexplained increase in your monthly energy bill, it may be time to check your air filter and see if it needs to be changed.
You Smell Foul Odors
Your HVAC system is directly responsible for any strange, burned, or musty scents present throughout your house. Odd smells from your HVAC system are frequently caused by poor or lowered air quality, a common symptom that your air filter needs to be replaced and is unclean.
