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.

Annoyingly, pet hair can adversely affect your air conditioning system. With proper maintenance, you can avoid impacting airflow and protect your cooling system from harm.

How Do AC Air Filters Work, and Why Are They Important?

Air filters are one of the most important parts of any forced-air HVAC system. Your air filter captures airborne contaminants, 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. The overall effectiveness of an air filter can be measured with its minimum efficiency reporting value (MERV), which could be anywhere from 1 to 20, with higher ratings indicating better 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 minimizing particulate matter, which often contribute to allergies, asthma attacks and similar conditions.

How Does Pet Hair Affect Your HVAC System and Filter?

When 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 microorganisms which can produce foul odors and lower indoor air quality.

Even with a filter in place, 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. 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, consisting of small skin flakes and saliva particles, is a common allergen that causes respiratory problems in people with allergies or asthma. You need a filter with a high MERV rating to 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 should try to replace it after 30 to 90 days. Check it every month and replace it when it starts to appear clogged.
  • Periodically clean the return air ducts: Pet hair can accumulate on air registers and grilles, reducing airflow. Trying cleaning these using 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.
  • Groom your pets: Regular brushing and bathing minimizes the hair your pet leaves behind. Keep the brushing outdoors and sweep the area after you've finished to keep any hair from getting back 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 washing any pet beds.
  • Keep the area around the outdoor unit clear: Central air conditioners feature an outdoor unit fixed to a concrete slab outside your home. Keep the area around this unit free of debris, like 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: For best results, have a trusted HVAC technician 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 air conditioning running efficiently with pets.
