What Can Animal Hair Do to My AC Filter?

Pets are an important part of many people’s lives. You probably consider your dog or cat a beloved family member and 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, keeping them from reaching other rooms or areas of the property. AC filters come in many different versions, including fiberglass, pleated and electrostatic. The overall effectiveness of an air filter can be measured with 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 cooling system components from dirt and debris that could lead to problems. At sufficient efficiency, the air 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?

While animals are shedding, their hair becomes airborne and can eventually get into 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 become clogged with moisture found in the cooling system, 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 draws it toward the HVAC system, the filter captures the hair as it passes, keeping it from landing on vulnerable cooling components. However, this clogs the filter more quickly than usual, limiting airflow and placing additional strain on the HVAC system. Without exchanging or cleaning the filter, higher energy bills and more repair visits could be likely.

What About Animal Dander?

Pet dander, consisting of microscopic skin flakes and saliva particles, is a common allergen that causes 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

Fortunately, it isn’t hard to protect the efficiency of your AC, even with pets living in your home. Here’s how:

• Stick to a regular schedule when cleaning or replacing the filter: Depending on the number of pets and the filter’s specific design, you should try to replace it after 30 to 90 days. Take a look at the filter each month and replace it if you notice weaker airflow or can see evidence of a clog.

• Periodically clean the return air ducts: Pet hair gradually piles up against the air registers and grilles, reducing airflow. 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.
• Keep pets well-groomed: Regular brushing and bathing is a great strategy for reducing pet hair. Brush your pets outside when possible 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 in corners. 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 HVAC systems need an outdoor unit secured 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 objects. This ensures effective heat transfer for more efficient operation.
• Don’t ignore preventive maintenance: An HVAC technician should inspect and maintain your cooling system once a year, preferably in the spring. They’ll know how to identify and fix small issues, clean key components and offer tips to keep your air conditioning running efficiently with pets.
