What Can Animal Hair Do to My AC Filter?

A family pet is part of millions of families. In fact, pets are usually considered part 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?

A filter is an important part of any forced-air HVAC system. It captures 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 corresponding to stronger filtration.

The primary purpose of an AC filter is to protect the evaporator coil, blower motor and other cooling system components from dirt and debris that could lead to problems. An efficient enough filter also improves indoor air quality by reducing particulates in the air, which can cause 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 can eventually get into the HVAC system through the return air ducts. Without a filter installed, pet hair accumulates within the evaporator coil, blower motor, fan blades and other components, reducing their efficiency and life span. 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 when the filter is already in place, pet hair isn’t harmless. When return airflow draws it toward the HVAC system, the filter captures the hair as it passes, keeping it from landing on vulnerable cooling components. That being said, eventually the filter will clog, 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, consisting of tiny skin flakes and saliva particles, is a common allergen that causes respiratory problems for those suffering from allergies or asthma. Filters with higher MERV ratings are more likely to 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 type of filter and how many pets you have, you should try to replace it after 30 to 90 days. Check it every month and replace it when a clog appears.
  • 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, call a professional for cleaning out the collected pet hair, dander and dust inside your ductwork every few years.
  • Groom your pets: Regular brushing and bathing minimizes the hair your pet leaves behind. Make sure to handle brushing outside and sweep the area afterward to prevent the hair from getting tracked inside.
  • Consistently vacuum and dust: Pet hair can be found in pretty much every room of a house. A lot of it settles on surfaces or under furniture. Proper cleaning should include vacuuming, sweeping, dusting and laundering your pet’s bedding.
  • Don’t let debris collect near the outdoor unit: Central HVAC systems need an outdoor unit fixed to a concrete slab just outside the home. Clear away any accumulated debris, such as pet hair, grass clippings, dead leaves, and other objects. This encourages normal heat transfer for more efficient operation.
  • Keep up with routine AC maintenance: Ideally, your local HVAC professional will inspect and maintain the air conditioner annually, preferably in the spring. This professional can find and resolve any small issues, clean key components and provide recommendations about how to keep your air conditioner running efficiently with pets.
