Don’t Neglect Your HVAC Filters: The Hidden Benefits of Regular Filter Changes

June 9, 2023

The HVAC system in your house or place of business is an essential feature that helps control the temperature, humidity, and air quality in your environment. However, many people overlook the importance of regularly changing their HVAC filters, which can lead to a ton of problems. Let’s discuss why changing your HVAC filters is so important, and what you can do to ensure that your system stays in good working order.

What Exactly do HVAC Filters do?

HVAC filters are responsible for trapping dust, dirt, pet dander, pollen, and other pollutants that can circulate through the air in your home or workplace. HVAC filters also help to protect your HVAC system from damage by preventing debris from accumulating on the system’s components and reducing the workload on the equipment. Over time though, filters can become clogged with debris, which will reduce their effectiveness and cause your HVAC system to work harder than it needs to. This can lead to higher energy bills, as well as premature wear and tear on your HVAC system.

Benefits of Regularly Changing your Filters

The main benefit of changing your HVAC filters is improved energy efficiency. When your filters become clogged, your HVAC system has to work harder to circulate air throughout your home or workplace. This can lead to higher energy bills and a shorter lifespan for your HVAC system. A dirty filter can also cause extensive damage to the coils, compressor and/or heat exchanger in your system. By changing your filters regularly, you can help reduce the workload on your HVAC system, which can lead to lower energy bills and a longer lifespan for your equipment

Another benefit of changing your HVAC filters regularly is improved indoor air quality. The air inside your home or workplace can be up to five times more polluted than the air outside, and your HVAC filters are the first line of defense against these pollutants because they remove harmful particles from the air. By changing your filters regularly, you can help ensure that your indoor air quality remains healthy and free of those harmful particles.

Changing your HVAC filters also helps to maintain the warranty on your equipment. Many HVAC manufacturers require regular filter changes as part of their warranty terms, and failure to do so could result in the voiding of your warranty. By staying on top of your filter changes, you can help ensure that your warranty remains valid and that you’re protected in case of any issues with your HVAC system.

How Often Should HVAC Filters be Changed? 

The answer depends on a few factors, such as the type of filter you’re using, the size of your home or workplace, and the number of people and pets that are present. As a general rule of thumb, it’s recommended that you change your filters every month. However, if you have pets, allergies, or live in an area with high levels of pollution, you may need to change your filters more frequently.

Types of HVAC Filters

When it comes to choosing the right type of HVAC filter, there are a few things to consider. The most common types of filters are fiberglass, pleated, and high-efficiency particulate air (HEPA) filters. Fiberglass filters are the least expensive but offer the least amount of protection against pollutants. Pleated filters are more effective and offer better protection against pollutants, but are also more expensive and restrictive of airflow. HEPA filters are the most effective and offer the best protection against pollutants, but are also the most expensive. You should also consider any specific needs you may have, such as allergies or pets. Some filters are designed to trap pet dander or allergens, while others may be better suited for environments with high levels of pollutants.
