What Can Animal Hair Do to My AC Filter?

Pets are an important part of many people’s lives. To be honest, our pets are usually considered a beloved member of the family and we want to have them around for many years-->

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. The filter is the primary solution to capture airborne particles, such as dust, pollen and pet hair, preventing these contaminants from circulating in your home. Various designs can be used effectively, including fiberglass, pleated and electrostatic. A filter’s effectiveness depends on its minimum efficiency reporting value (MERV), which ranges 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 important parts from dirt and debris that could cause damage. An efficient enough filter also improves indoor air quality by reducing particulates in the air, which can cause allergies, asthma attacks and other respiratory issues in sensitive individuals.

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

When pets shed, their hair becomes airborne and may gradually reach the HVAC system through the return air ducts. Without a filter installed, pet hair collects inside 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 with a filter in place, pet hair can still lead to problems. When return airflow arrives at the HVAC system, the filter traps the hair and prevents it from landing on sensitive cooling components. At the same time, this quickly clogs the filter up, decreasing airflow and increasing strain on the HVAC system. Without exchanging or cleaning the filter, you may experience higher energy bills and more frequent breakdowns.

What About Animal Dander?

Pet dander, consisting of small skin flakes and saliva particles, commonly exacerbates 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

You can take steps to maintain the efficiency of your air conditioner, 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 it starts to appear clogged.

• Keep ventilation clear: Pet hair gradually piles up against the air registers and grilles, preventing proper ventilation. You can clean them 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.
• Bathe or brush away excess pet hair: Regular brushing and bathing reduces the hair and dander your pets generate. Keep the brushing outdoors and sweep the area when you’re done to stop hair from just drifting back 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.
• Clear the area around the outdoor unit: Central air conditioners feature an outdoor unit mounted to a concrete slab outside your home. Keep the area around this unit free of debris, such as pet hair, grass clippings, dead leaves, and similar materials. This helps maintain consistent heat transfer for more efficient operation.
• Schedule regular maintenance: An HVAC technician should inspect and maintain your cooling system once a year, preferably in the spring. This professional can identify and fix small issues, clean internal components and offer tips to keep your air conditioning running efficiently with pets.
