Air filters are an essential part of your home’s HVAC system, and they accomplish an abundance of important functions to keep your home’s heating and cooling system functioning optimally. However, in order for air filters to properly work, you have to change them regularly.
It may seem like a trivial concern, but changing your home’s air filter is kind of a big deal. Here are just a few compelling reasons why it’s important to change your HVAC system’s air filter.
Better Indoor Air Quality
What’s more important than the air you breathe inside your home? Not much. Indoor air quality is a major factor in both your health and well-being, and having a dirty air filter can negatively impact the quality of your home’s indoor air. Think about it this way, if you’re breathing in air that continually passes through a filthy air filter, you’re not doing yourself any good. Changing your home’s air filter is a simple an effective way to improve your home’s indoor air quality immediately.
Allowing dirt and debris to clog up your air filter not only makes your air dirtier, but it also can cause a major decline in the efficiency of your home’s HVAC system. Experts estimate that by neglecting to change a dirty air filter, you may be reducing your HVAC system’s efficiency up to 15%! That’s no small reduction in efficiency, especially when you consider what that means for your system over the long run.
A less efficient system can cost you a lot of extra money in energy bills, and, constantly running an inefficient system will decrease its lifespan. So, play it safe and replace your air filter. Investing a few dollars per month towards a new air filter could save you hundreds of dollars in energy bills over the lifetime of your system.
Mold and Mildew Growth
Preventing growth of mold and mildew is a very good reason to regularly change your filter. When dirty filters come in contact with water condensation, mold and mildew can result. This can not only cause problems for your HVAC system, but the presence of mold in your air filter can cause serious health concerns, especially for allergy sufferers.
How Often Should a Filter Be Changed?
We recommend checking your HVAC system’s air filter once per month, and change it whenever it appears dirty. If your home has pets, a lot of regular foot traffic, or inadequate ventilation, you’ll want to change it more often. You may also consider upgrading to a HEPA filter for maximum air filtration.
If it’s been a while since you’ve had your HVAC system checked, you’ll want to have that done as well. Fortunately, maintenance only needs performed once or twice per year. By having your system serviced annually, you’ll experience far less problems with your HVAC system over time.
