How Dirty Air Filters Affect Your Home

dirty air filtersHave you ever wondered why we emphasize the importance of changing your air filter regularly? You may be surprised by the answer. You may think that dirty air filters simply contaminate the air; however, that is not the complete answer. Air filters do much more than remove particles from the air and prevent them from returning into the air you breathe. They also block particles from causing damage to the inside of your air conditioner. When an air filter is dirty, it is unable to do its job efficiently. So, what are the real reasons you need to change your air filter once a month? Here are the top 4 ways a dirty air filter can affect your home.

#1: Dirty Air Filters = Feeling Less Comfortable

The air filter may appear to be a small component of your HVAC system, but it plays a big role. Clean air filters allow air to flow through your home efficiently. If your air filters are dirty, airflow is restricted, affecting the amount of cool air circulating throughout your home. When this happens, there isn't enough air being put back into your home to keep you cool or warm. You may also start to notice hot and cold spots throughout your home and a feeling that the temperature you feel does not match the thermostat reading. If this is the situation in your home, a dirty air filter may be the culprit; however, discomfort is the least of your worries

#2: Air Conditioner Leaks

To cool the air in your home, air conditioning systems use a refrigerant that, as it is circulated, changes from a gas to a liquid. During this process, the heat from your home is trapped and expelled.  As the refrigerant is evaporated in the indoor evaporator coil, it absorbs the heat from air blowing over the coil. When the air filter is dirty, warm air becomes limited. This could cause the coil to freeze.

As the coil thaws, water could begin to leak into your home, causing structural damage. If you notice condensation or water around your HVAC system, a frozen coil is the culprit, and there may be other issues within the system as well. Changing your filter monthly prevents this from happening.

#3: Higher Energy Bills

An air filter that is not replaced on a regular basis will become clogged with large amounts of airborne particles. With further neglect, it will become completely blocked, forcing dust and mold back into your indoor air. Dirty air filters also restrict air flow putting strain on your HVAC equipment as the fan has to work even harder to try to bring in the right amount of air. As the system works harder, it uses more energy, therefore increasing your energy bills. Make sure you check your filter monthly and clean or replace it according to the manufacturer’s directions. Changing your air filter every 30 days is one of the easiest ways to lower your monthly utility bills!

#4: AC/Heating System Damage

HVAC systems were designed to take in a specific amount of air each time they cycle. When airflow is impeded, the system components have to work harder. More wear and tear on a system in a season may mean your HVAC system will fail you when you need it most. It is important that the airflow not be constricted or impeded, or the strain placed on your furnace/AC unit will cause less efficiency and can eventually lead to damage to multiple components of your unit.

Air filters do come at a price, but that cost is much less than an emergency call to your local HVAC company. Change your air filters regularly and have your HVAC system inspected annually to ensure it is running properly. Looking for a heating and cooling contractor to inspect your HVAC system?
