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, pet hair can adversely affect your air conditioning system. With proper maintenance, you can ensure adequate airflow and protect the cooling equipment from harm.
A filter is an important part of any forced-air HVAC system. It captures airborne particles, such as dust, pollen and pet hair, preventing these contaminants from circulating in your home. AC filters come in many different versions, 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 indicating better filtration.
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 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.
When pets shed, their hair becomes airborne and is drawn into the HVAC system through the return air ducts. Without a filter installed, pet hair can build up on 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 mold and bacteria that can generate foul odors and lower indoor air quality.
Even with a filter in place, 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 delicate cooling components. However, this clogs the filter more quickly than usual, decreasing airflow and increasing strain on the HVAC system. Without intervention, you may experience higher energy bills and more frequent breakdowns.
Pet dander, which consists of microscopic skin flakes and saliva particles, is a common allergen that causes 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.
