What Can Animal Hair Do to My AC Filter?

A family pet is part of millions of families. You probably consider your dog or cat a beloved family member and want to have them around for many years.

Annoyingly, pet hair can adversely affect your air conditioning system. But with routine maintenance, you can ensure adequate airflow and protect your air conditioner 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. It captures airborne particles, such as dust, pollen and pet hair, stopping them from spreading through the ductwork. Various designs can be used effectively, including fiberglass, pleated and electrostatic. A filter’s effectiveness depends os its minimum efficiency reporting value (MERV), which is rated on a scale 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 important parts from dirt and debris that could cause damage. At sufficient efficiency, the air filter also improves indoor air quality by reducing particulates in the air, which can cause allergies, asthma attacks and other breathing problems.

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 can build up on 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 isn’t harmless. When return airflow arrives at the HVAC system, the filter captures the hair as it passes, keeping it from landing on vulnerable cooling components. However, this clogs the filter more quickly than usual, decreasing airflow and increasing strain on the HVAC system. Without maintenance, higher energy bills and more repair visits could be likely.

What About Animal Dander?

Pet dander, which consists of microscopic skin flakes and saliva particles, commonly exacerbates respiratory problems in people with 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:

  • Stick to a regular schedule when cleaning or replacing the filter: Depending on the type of filter and how many pets you have, you should try to replace it after 30 to 90 days. Take a look at the filter each month and replace it when a clog appears.
  • Periodically clean the return air ducts: Pet hair collects on the air registers and grilles, limiting circulation. You can clean them 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 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 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 around the house. Proper cleaning should include 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 secured to a concrete slab outside your home. Clear away any accumulated debris, like pet hair, grass clippings, dead leaves and other forms of yard waste. This ensures effective 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 conditioning running efficiently with pets.
