Your air conditioner’s filter is an often-overlooked but important part of your HVAC system. If it’s been a while since you’ve changed your AC filter, you could unintentionally be posing a health risk to yourself, your family and pets. Let’s learn more about AC filters and why they must be changed regularly to keep your home safe and healthy.


1). They Harbor Allergens

Dirty air filters can become overrun with dust, pet dander, mold spores, and other pollutants. When the filter can no longer trap these particles, they circulate through your ductwork and into your breathable air. This isn’t ideal for anyone, but it’s especially dangerous for family members with allergies, asthma, or other respiratory issues. Be sure to inspect your air filters frequently to make sure they’re still effective. Then call a professional like H&H Heating and Air to evaluate your HVAC system and discuss your options for improving the air quality in your home.


2). Your Air Conditioner Could Freeze

A clean air filter allows air to flow freely out of your air conditioning unit, but a dirty one hinders the flow of air. If the buildup of dirt is especially bad, very little air flow will get through. This traps the cold air inside the unit and lowers its internal temperature. This can cause the unit to freeze up and the coils to become icy. While the unit is trying its hardest to circulate the cool air, the temperature in your home will not benefit because the air can’t get through.


3). Continual Cycling

You might hear clicking from your AC unit when it cycles on or off throughout the day. This is normal. When your air filter is dirty, it makes your AC unit work harder to cool your home. As a result, your air conditioner will go through short-cycling, which is when the unit turns on and off more often than usual to try and lower your home’s temperature. This is hard on your system and could prematurely age it.


4). Increased Wear and Tear

To keep your AC unit working well for as long as possible, it needs proper maintenance and frequent air filter changes. When dust and dirt are allowed to build up, they can affect the unit’s internal components. Particularly bad build-up causes extra wear and tear that can lead to costly repairs in the future. You could even be forced to pay for a new unit much too soon. Routine maintenance can add years to your AC unit’s life and keep its energy efficiency high – and your cooling bills low – in the meantime.
