What Can Animal Hair Do to My AC Filter?

A family pet is part of millions of families. 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. 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 corresponding to stronger filtration.

An air filter’s key purpose is the protection of the evaporator coil, blower motor and other delicate hardware from dirt and debris capable of damaging them. An efficient enough filter also improves indoor air quality by minimizing particulate matter, which often contribute to allergies, asthma attacks and other breathing problems.

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. If there isn’t a filter in place, pet hair accumulates within the evaporator coil, blower motor, fan blades and other components, potentially stopping them from working efficiently. 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.

But even if you have an air filter installed, pet hair isn’t harmless. When return airflow draws it toward the HVAC system, the filter does its job by trapping the hair and preventing it from landing on vulnerable cooling components. That being said, eventually the filter will clog, decreasing airflow and increasing strain on the HVAC system. Without exchanging or cleaning the filter, high energy bills and frequent breakdowns may be right behind.

What About Animal Dander?

Pet dander, made up of tiny skin flakes and saliva particles, commonly exacerbates respiratory problems in people with 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

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 total number of pets as well as the filter’s efficiency, 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.

• Periodically clean the return air ducts: Pet hair collects on the air registers and grilles, preventing proper ventilation. 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 in the air ducts 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 when you’re done to stop hair from just drifting 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 or under furniture. Proper cleaning should include vacuuming, sweeping, dusting and washing any pet beds.
• Don’t let debris collect near the outdoor unit: Central air conditioning systems come with 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 helps maintain consistent heat transfer for more efficient operation.
• Don’t ignore preventive maintenance: For best results, have a trusted HVAC technician 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 cooling system running efficiently with pets.
