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 keep them well-cared for.

Regrettably, pet hair usually has a negative impact on the efficiency of 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. Your filter's effectiveness can be illustrated with its minimum efficiency reporting value (MERV), which ranges from 1 to 20, with higher ratings corresponding to stronger filtration.

Your filter is primarily responsible for protecting 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 reducing particulates in the air, which often contribute to allergies, asthma attacks and similar conditions.

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

As pets shed, 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 mix with condensation formed during air conditioning, creating a breeding ground for mold and bacteria that can generate foul odors and lower indoor air quality.

Even with a filter in place, pet hair can still lead to problems. When return airflow arrives at the HVAC system, the filter does its job by trapping the hair and preventing it from landing on delicate cooling components. However, this clogs the filter more quickly than usual, putting extra strain on the HVAC system. Without intervention, high energy bills and frequent breakdowns may be right behind.

What About Animal Dander?

Pet dander, which consists of small skin flakes and saliva particles, is a common cause of 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

Fortunately, it isn't hard to protect the efficiency of your AC, even with pets living in your home. Here’s how:

  • Change the filter regularly: Depending on the number of pets and the filter's specific design, you should try to replace it after 30 to 90 days. Keep an eye on it every month and replace it if you notice weaker airflow or can see evidence of a clog.
  • Keep ventilation clear: Pet hair gradually piles up against the air registers and grilles, reducing airflow. Clean these with 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.
  • Bathe or brush away excess pet hair: 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: Not all pet hair ends up in the HVAC system. A lot of it settles on surfaces or under furniture. Keep up a regular cleaning routine that includes vacuuming, sweeping, dusting and laundering your pet’s bedding.
  • Clear the area around the outdoor unit: Central air conditioning systems come with an outdoor unit mounted to a concrete slab somewhere along an exterior wall of 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 ensures effective heat transfer for more efficient operation.
  • Schedule regular maintenance: Ideally, your local HVAC professional will inspect and maintain your air conditioning system every year, preferably in the spring. They can find and resolve any small issues, clean key components and provide recommendations about how to keep your cooling system running efficiently with pets.
