The How and Why of Air Filters

Your air filter plays an integral role in your HVAC system’s ability to effectively heat and cool your home. Air filters improve indoor air quality and protect the HVAC unit’s moving parts by removing particles from the indoor air. Learn why regularly changing the air filter in your Foley, Alabama, home is so important.

Remove Allergens From the Home

Air filters catch the larger pollutants in your home, such as dust and pet hair, so they don’t reenter the system. Consequently, those particles don’t get redistributed throughout your home. If anyone in your family suffers from allergies or asthma, your air filter becomes even more critical.

Reduce Wear and Tear

If your air filter gets clogged, air can’t pass as easily through the fibers. Your HVAC system has to work even harder to heat or cool your home, which means it incurs more wear and tear. The result is the need for increased repairs or even premature replacement of parts. Additionally, this increased effort from your system means more energy is consumed and therefore, you will incur higher utility bills.

Prevent Pressure Drops

Similarly, a dirty air filter can result in an airflow pressure drop in your HVAC system. The air doesn’t move as forcefully through the air conditioner, furnace, or heat pump, which means increased difficulty providing the right level of air conditioning. Your unit will have to work harder and might break down entirely if the situation continues.

Change Your Air Filter

Using the highest quality air filter possible that is recommended for your system will help to prevent major problems. Disposable air filters present the most common solution, but you can also find washable air filters that you can clean and reuse.

Your HVAC system contains far more expensive parts than the air filter, but the filter performs an essential function. To learn more about indoor air quality and air filters, call Keith Air Conditioning, Inc. today at 251-476-3610 to schedule an appointment with one of our technicians.
