Midsummer AC Care: Change Your Air Filter!

person's hand changing air filter in HVAC systemThis isn’t new information—pretty much any HVAC professional you talk to is going to say it’s necessary that you replace your Nederland, TX air conditioning system’s air filter every 1-3 months during periods of use, depending on the level of contaminants in your home and the type of air filter you have. If you have a reusable filter in your AC—which is pretty common in small, portable systems, then you’ll want to clean it and let it fully dry before putting it back in.

But, why? If you don’t have indoor air quality problems, is it really that important that you change out or clean your air filter on a regular basis? Well, yes—because the air filter is not necessarily there for your health, but rather the health of your air conditioner.

Air Filters: Not Intended for Indoor Air Quality Improvement

Sure, the air filters on the market today can give you a basic level of filtration that helps a little if you have allergy or asthma symptoms. Many of the most common and basic allergens are trapped in the filter, so they can’t recirculate through the home. However, that’s not the purpose of your air filter.

Early on in the design phase of air conditioning systems and central furnaces, manufacturers and engineers discovered that without an air filter in place, the debris circulating through the air could pummel the fan, damage system components, and reduce AC system airflow.

Your AC Can’t Perform Efficiently without Its Air Filter

Essentially, an air filter acts as protection for your HVAC system. So when it’s dirty, it doesn’t allow that HVAC system to efficiently or effectively do its job. A dirty air filter is too clogged up to allow more dirt through, sure—but it’s also going to be too clogged to allow proper airflow in.

Your air conditioner must be able to pull in air from your living space in order to operate. Without this functionality, the system’s fan can malfunction, as can various components such as the evaporator coil that relies on the temperature and volume of the indoor air to function.

A dirty/clogged air filter in your air conditioner can lead to any or all of the following AC troubles:

  • Reduced Performance: Without the right level of airflow, the cycle of your air conditioner may be longer or shorter (called short-cycling) than usual, causing your air conditioner to work harder than it should have to and essentially wearing it down faster.
  • Overworked Fans: The fans in your air conditioner also have to work harder, in order to pull in air through a clogged filter. This can lead to problems with the motor, which will probably need to be replaced.
  • Frozen Coil: The coil in your central air conditioner or heat pump can actually freeze up when there is not enough warm air flowing over it, creating an insulating barrier and preventing the absorption of heat, which is required for your air conditioner to operate.
  • Higher Energy Bills: Because of how hard your air conditioner has to work to do its job when its air filter is too clogged up, you’ll soon see higher energy bills, but without the comfort that you deserve.
