3 Things That Can Go Wrong When You Don't Change AC Filter

Man replacing AC filter at home

There are many essential components of a working AC system. As a homeowner, it's important to perform routine maintenance on your air conditioning system to ensure durability and quality air circulation. Your AC's air filter is one of those parts that need regular maintenance for optimal performance. Changing your air filter is one of the easiest maintenance tasks you can perform on your HVAC system, but it's also one of the easiest to overlook. Not changing your AC's air filter can wreak havoc on your unit and can even cause it to fail. You should know the common problems that can occur when you don't change your air filter on a regular basis.

Consequences of Not Changing Your Air Filter

1. Higher Energy Cost

A dirty air filter causes the HVAC system to run longer in order to cool a room. This happens because as the air filter becomes clogged with particles and debris, the ability for air to move through the filter diminishes. As the AC runs longer, it uses much more power to cool your home, and thus, reduces the efficiency of the system. This results in a higher energy bill. When you compare the few dollars it takes to buy a new air filter to the money you will save on your electric bill, you'll be pleased with the significant savings you'll see.

2. Allergen Buildup

A clogged air filter can lead to dust and other contaminants entering ductwork, blower fans, and other parts. This then leads to a buildup in the unit. As the contaminants enter the HVAC system, moving components get clogged and jammed. The system often has to work harder to circulate air throughout your home. It can cause the spinning fan blade and air pressure in your HVAC system to force allergens into the air, onto difference surfaces, crevices, heating and cooling coils, and electrical and mechanical components. As the particles remain in the air and build up inside the unit, they can block airflow and cause damage to the system.

3. Poor Air Quality

When you don't change your air filter on a routine basis, pollen or dander are more likely to enter your home. Mold can also begin to form in the structure. These contaminants can cause minor problems like watery eyes, sneezing, and coughing, or serious problems like asthma-related symptoms and other long-term respiratory complications.

Benefits of Changing Your Air Filter

There are various benefits to changing your AC's air filter including:

  • Longer lifespan - A clogged air filter can cause your HVAC system to malfunction, which could lead to costly repairs later. Installing a new air filter regularly can increase the durability of your unit.
  • Better indoor air quality - A fresh air filter promotes a cleaner, fresher, and healthier air free of dust, pollen, allergens, and other contaminants. Quality air is important for every member of your household, especially children, the elderly, and those suffering from allergies and/or asthma.
  • Increased efficiency - Replacing your clogged air filter will save you a significant amount on operating costs. Because it has to work harder to filter the air, a dirty filter uses a lot more energy than a new air filter.
  • Environmentally friendly - As an HVAC system with a dirty air filter works harder to cool the air and keep it clean, large amounts of carbon monoxide and other greenhouse gases start to release into the outdoor air. A clean air filter protects the environment from greenhouses gases and reduces the amount of energy being used.

Staying On Top of Air Filter Maintenance 

It's recommended that you mark your calendar every 30 to 90 days to change your air filter to ensure the optimal performance of your air conditioning unit. Contact American Air Cares today for more information.
