A family pet is part of millions of families. You probably consider your dog or cat a beloved family member and want to keep them well-cared for.
Annoyingly, pet hair can adversely affect your air conditioning system. But if you keep up with maintenance, you can ensure adequate airflow and protect your cooling system from harm.
Your air filter is a key component of the HVAC system. Your air filter captures airborne contaminants, such as dust, pollen and pet hair, keeping them from reaching other rooms or areas of the property. 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 is rated on a scale from 1 to 20, with higher ratings indicating better filtration.
Your filter is primarily responsible for protecting 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 similar conditions.
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, 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 mold and bacteria that can generate foul odors and lower indoor air quality.
Even when the filter is already in place, pet hair isn’t harmless. When return airflow arrives at the HVAC system, the filter does its job by trapping the hair and preventing it from landing on sensitive cooling components. That being said, eventually the filter will clog, decreasing airflow and increasing strain on the HVAC system. Without intervention, high energy bills and frequent breakdowns may be right behind.
Pet dander, consisting of tiny skin flakes and saliva particles, is a common allergen that causes respiratory problems in people with allergies or asthma. You may benefit from a higher efficiency filter to ensure it can effectively capture and remove dander, which is much smaller than pet hair.
Fortunately, it isn’t hard to protect the efficiency of your AC, even with pets living in your home. Here’s how:
