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?

Air filters are one of the most important parts of any forced-air 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. AC filters come in many different versions, including fiberglass, pleated and electrostatic. Your filter’s effectiveness can be illustrated with its minimum efficiency reporting value (MERV), which could be anywhere 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 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 could lead to 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 may gradually reach 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 become clogged with moisture found in the cooling system, creating a breeding ground for mold and bacteria that can generate foul odors and lower indoor air quality.

Even when the filter is already in place, pet hair isn’t harmless. When return airflow reaches the main HVAC system, the filter captures the hair as it passes, keeping it from landing on delicate cooling components. However, this clogs the filter more quickly than usual, putting extra strain on the HVAC system. Without maintenance, higher energy bills and more repair visits could be likely.

What About Animal Dander?

Pet dander, consisting of tiny 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

Maintaining an efficient, properly functioning air conditioner is certainly possible, 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 may need a new filter every 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.
  • Clean your air vents and ductwork: Pet hair can accumulate on air registers and grilles, limiting circulation. Trying cleaning these using 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 reduces the hair and dander your pets generate. Brush your pets outside when possible and sweep the area afterward to prevent the hair from getting tracked 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 or under furniture. Keep up a regular cleaning routine that includes vacuuming, sweeping, dusting and laundering your pet’s bedding.
  • Keep the area around the outdoor unit clear: Central air conditioners feature an outdoor unit mounted to a concrete slab just outside the home. Clear away any accumulated debris, including pet hair, grass clippings, dead leaves, and similar materials. This helps maintain consistent heat transfer for more efficient operation.
  • Don’t ignore preventive maintenance: An HVAC technician should inspect and maintain your air conditioning system every year, preferably in the spring. They’ll know how to find and resolve any small issues, clean key components and share advice on keeping your cooling system running efficiently with pets.
