Your heating and air conditioning system is one of the most probably expensive appliances in your Charleston, SC home. To help get the most value out of your HVAC system can be as easy as changing out your air filters regularly , seems simple right? More often than not, Charleston, SC homeowners ignore the importance of the filters in their heating and air conditioning system. This can lead to higher energy bills, poor indoor air quality, damaged HVAC equipment, and more.


Air filters are generally made of pleated paper or spun fiberglass and then surrounded by a cardboard frame. They are inserted into a specific place in your HVAC system and they act as a barrier to prevent pollutants and contaminants from circulating into the air. Some of the most common things that air filters block are dust, pollen, hair, lint, bacteria.


Depending on your Charleston, SC home living situation and the type of filter you are using, there are different   when it comes to changing out your air filters. A popular rule of thumb is to change out your air filters every 1-2 months, however, there are some differences, such as  the number of people and pets in your home can make this number smaller or larger. We recommend checking on your air filters once a month. Most of the time it is best to change them at this time just to be safe.


  1. Increase in Energy Bills – When your air filters are dirty, your HVAC system has to work harder in order to heat and/or cool your home. That means that you’re using more energy without seeing or feeling the benefits of energy consumption.
  2. Decrease in Indoor Air Quality – When your air filters are dirty, they can no longer trap the pollutants & contaminants as well as they once could. That means your home’s indoor air quality will suffer and you’ll have unwanted pollutants floating and circulating throughout the air inside of your Charleston, SC home.
  3. Reduced Home Comfort – Because your air filters are acting as blockages in your HVAC system. That means your home will not be as comfortable as you want it to be.
  4. This can lead to early failures and costly repairs or breakdowns. Because your heating and cooling system is so expensive, you ideally want to run it as little as possible. With dirty air filters, you will find yourself having to run your HVAC system more often.
