What Can Animal Hair Do to My AC Filter?

A family pet is part of millions of families. You probably consider your dog or cat a beloved family member and 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. It captures 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 ranges 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 delicate hardware from dirt and debris that could lead to problems. At sufficient efficiency, the air 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 Does Pet Hair Affect Your HVAC System and Filter?

While animals are shedding, 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 microbes like mold, which give off 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 captures the hair as it passes, keeping it from landing on delicate cooling components. However, this clogs the filter more quickly than usual, limiting airflow and placing additional strain on the HVAC system. Without intervention, 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 cause of respiratory problems in people with 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 may need a new filter every 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.

• Keep ventilation clear: 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. 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: Not all pet hair ends up in the HVAC system. A lot of it settles on surfaces or in corners. Proper cleaning should include vacuuming, sweeping, dusting and washing any pet beds.
• Keep the area around the outdoor unit clear: Central air conditioning systems come with an outdoor unit fixed to a concrete slab somewhere along an exterior wall of the home. Keep the area around this unit free of debris, such as pet hair, grass clippings, dead leaves, and other forms of yard waste. This ensures effective heat transfer for more efficient operation.
• Don’t ignore preventive maintenance: An HVAC technician should inspect and maintain the air conditioner annually, preferably in the spring. They can identify and fix small issues, clean key components and offer tips to keep your cooling system running efficiently with pets.
