What Can Animal Hair Do to My AC Filter?

A family pet is part of millions of families. To be honest, our pets are usually considered a beloved member of the family and we want to have them around for many years-->

How Does an AC Filter Work, and Why is It So Important?

Air filters are one of the most important parts of any forced-air HVAC system. The filter is the primary solution to capture airborne particles, such as dust, pollen and pet hair, keeping them from reaching other rooms or areas of the property. There is lots of variety in the materials they use to accomplish this, including fiberglass, pleated and electrostatic. A filter’s effectiveness depends on its minimum efficiency reporting value (MERV), which could be anywhere from 1 to 20, with higher ratings illustrating maximum efficiency.

The primary purpose of an AC filter is to protect the evaporator coil, blower motor and other cooling system components from dirt and debris capable of damaging them. An efficient enough filter also improves indoor air quality by minimizing particulate matter, which often contribute to allergies, asthma attacks and other breathing problems.

How Can Pet Hair Impact an HVAC System’s Air Filter?

While animals are shedding, their hair becomes airborne and can eventually get into the HVAC system through the return air ducts. When the filter is missing, pet hair accumulates within the evaporator coil, blower motor, fan blades and other components, slowing them down and reducing efficiency. Hair can also become clogged with moisture found in the cooling system, creating a breeding ground for microbes like mold, which give off foul odors and lower indoor air quality.

But even if you have an air filter installed, pet hair can still lead to problems. When return airflow draws it toward the HVAC system, the filter captures the hair as it passes, keeping it from landing on delicate cooling components. However, this clogs the filter more quickly than usual, limiting airflow and placing additional strain on the HVAC system. Without exchanging or cleaning the filter, you may experience higher energy bills and more frequent breakdowns.

What About Animal Dander?

Pet dander, consisting of tiny skin flakes and saliva particles, commonly exacerbates respiratory problems for those suffering from allergies or asthma. You may benefit from a higher efficiency filter to ensure it can effectively capture and remove dander, which is much smaller than pet hair.

How to Care for Your AC System and Filter with Pets

You can take steps to maintain the efficiency of your air conditioner, even with pets living in your home. Here’s how:

• Change the filter regularly: Depending on the type of filter and how many pets you have, you might need to replace it every 30 to 90 days. Keep an eye on it every month and replace it when a clog appears.

• Periodically clean the return air ducts: Pet hair gradually piles up against the air registers and grilles, limiting circulation. Clean these with the brush attachment on your vacuum cleaner as often as needed. Then, call a professional for cleaning out the collected pet hair, dander and dust in the air ducts every few years.
• Keep pets well-groomed: Regular brushing and bathing is a great strategy for reducing pet hair. Make sure to handle brushing outside and sweep the area afterward to prevent the hair from getting tracked inside.
• Consistently vacuum and dust: While it affects your HVAC system, pet hair can be found all throughout your home. A lot of it settles on surfaces or under furniture. Proper cleaning should include vacuuming, sweeping, dusting and washing any pet beds.
• Don’t let debris collect near the outdoor unit: Central air conditioners feature an outdoor unit secured to a concrete slab just outside the home. Keep the area around this unit free of debris, including pet hair, grass clippings, dead leaves, and other forms of yard waste. This helps maintain consistent heat transfer for more efficient operation.
• Keep up with routine AC maintenance: An HVAC technician should inspect and maintain your air conditioning system every year, preferably in the spring. They’ll know how to identify and fix small issues, clean key components and share advice on keeping your cooling system running efficiently with pets.
