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.

Unfortunately, pet hair can adversely affect your air conditioning system. But if you keep up with maintenance, you'll help preserve steady 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. Your air filter captures airborne contaminants, such as dust, pollen and pet hair, preventing these contaminants from circulating in your home. There is lots of variety in the materials they use to accomplish this, including fiberglass, pleated and electrostatic. A filter’s effectiveness depends os its minimum efficiency reporting value (MERV), which could be anywhere from 1 to 20, with higher ratings illustrating maximum efficiency.

Your filter is primarily responsible for protecting the evaporator coil, blower motor and other delicate hardware 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 could lead to allergies, asthma attacks and other respiratory issues in sensitive individuals.

How Can Pet Hair Impact an HVAC System's Air Filter?

As pets shed, their hair becomes airborne and is drawn 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, slowing them down and reducing efficiency. Hair can also encourage clogs if it interacts with the moisture inside your cooling, 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 reaches the main HVAC system, the filter captures the hair as it passes, keeping it from landing on delicate cooling components. That being said, eventually the filter will clog, 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, is a common cause of respiratory problems for those suffering from 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 total number of pets as well as the filter's efficiency, 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 collects on the air registers and grilles, preventing proper ventilation. 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 inside your ductwork every few years.
  • Groom your pets: Regular brushing and bathing is a great strategy for reducing pet hair. Keep the brushing outdoors 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. Keep up a regular cleaning routine that includes vacuuming, sweeping, dusting and laundering your pet’s bedding.
  • Don't let debris collect near 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 encourages normal heat transfer for more efficient operation.
  • Don't ignore preventive maintenance: Ideally, your local HVAC professional will inspect and maintain your air conditioning system every year, preferably in the spring. They can identify and fix small issues, clean key components and provide recommendations about how to keep your air conditioning running efficiently with pets.
