What Can Animal Hair Do to My AC Filter?

Pets are an important part of many people’s lives. In fact, pets are usually considered part of the family, and we want to keep them well-cared for.

Unfortunately, pet hair can adversely affect your air conditioning system. But with routine maintenance, you can avoid impacting airflow and protect your air conditioner from harm.

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

Your air filter is a key component of the HVAC system. The filter is the primary solution to capture airborne particles, such as dust, pollen and pet hair, stopping them from spreading through the ductwork. There is lots of variety in the materials they use to accomplish this, including fiberglass, pleated and electrostatic. The overall effectiveness of an air filter can be measured with its minimum efficiency reporting value (MERV), which is rated on a scale from 1 to 20, with higher ratings illustrating maximum efficiency.

Your filter is primarily responsible for protecting the evaporator coil, blower motor and other important parts from dirt and debris capable of damaging them. At sufficient efficiency, the air filter also improves indoor air quality by reducing particulates in the air, which could lead to allergies, asthma attacks and similar conditions.

How Does Pet Hair Affect the Air Filter of My HVAC System?

When pets shed, their hair becomes airborne and is drawn into the HVAC system through the return air ducts. If there isn’t a filter in place, pet hair collects inside the evaporator coil, blower motor, fan blades and other components, potentially stopping them from working efficiently. 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 traps the hair and prevents it from landing on sensitive cooling components. At the same time, this quickly clogs the filter up, limiting airflow and placing additional strain on the HVAC system. Without maintenance, high energy bills and frequent breakdowns may be right behind.

What About Animal Dander?

Pet dander, which consists of microscopic skin flakes and saliva particles, is a common allergen that causes 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:

  • Stick to a regular schedule when cleaning or replacing the filter: Depending on the number of pets and the filter’s specific design, you may need a new filter every 30 to 90 days. Check it every month and replace it when a clog appears.
  • Clean your air vents and ductwork: Pet hair can accumulate on air registers and grilles, limiting circulation. Trying cleaning these using the brush attachment on your vacuum cleaner as often as needed. Then, hire a professional to remove built-up pet hair, dander and dust inside your ductwork every few years.
  • Keep pets well-groomed: Regular brushing and bathing is a great strategy for reducing pet hair. Keep the brushing outdoors and sweep the area after you’ve finished to keep any hair from getting back 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 in corners. Keep up a regular cleaning routine that includes vacuuming, sweeping, dusting and laundering your pet’s bedding.
  • Keep the area around the outdoor unit clear: Central air conditioners feature an outdoor unit fixed to a concrete slab somewhere along an exterior wall of the home. Clear away any accumulated debris, including pet hair, grass clippings, dead leaves, and other forms of yard waste. This helps maintain consistent heat transfer for more efficient operation.
  • Schedule regular maintenance: An HVAC technician should inspect and maintain your air conditioning system every year, preferably in the spring. They can identify and fix small issues, clean internal components and offer tips to keep your air conditioner running efficiently with pets.
