We love our pets, but all that fur, dander, and dirt they bring into the house can be tough on your HVAC system. Pet hair and airborne particles can build up in filters, vents, and equipment, potentially reducing airflow and making your system work harder.
A few simple habits can help keep your HVAC system running efficiently while keeping your home comfortable for everyone—two-legged and four-legged alike.
Your HVAC filter captures dust, pet hair, dander, and other particles before they circulate through your system. In a home with pets, that filter may become dirty much faster.
Instead of relying only on a set replacement schedule, check your filter about once a month. Replace it whenever it looks dirty or according to the filter manufacturer’s recommendations.
Homes with multiple pets or heavy-shedding breeds may need filter changes more frequently.
A better filter can help capture smaller particles such as pet dander, but that doesn’t mean you should automatically buy the filter with the highest rating.
Higher-efficiency filters can create more resistance to airflow, and not every HVAC system is designed to handle them. Restricted airflow can reduce performance and put additional strain on your equipment.
If you’re unsure which filter is best for your home, ask your HVAC technician what your system can safely accommodate.
The less pet hair floating around your home, the less of it your HVAC system has to deal with.
Regularly vacuuming carpets, rugs, furniture, and areas where your pets spend the most time can help reduce the amount of hair and dander that reaches your HVAC filter.
Don’t forget about the areas around your return-air grilles. Pet hair can collect around them because they’re constantly pulling air toward the HVAC system.
Pets have a talent for finding the most comfortable spot in the house—which sometimes happens to be directly on top of an HVAC vent.
Make sure supply vents and return-air grilles aren’t blocked by pet beds, toys, furniture, or other household items. Your HVAC system depends on proper airflow to heat and cool your home effectively.
If you notice pet hair accumulating on a vent or grille, vacuum or wipe it clean.
Regular brushing and grooming doesn’t just help keep your furniture cleaner. It can also reduce the amount of loose fur and dander circulating throughout your home.
If possible, brush heavy-shedding pets outside or in an area that’s easy to clean. The more loose hair you catch before it becomes airborne, the less likely it is to end up in your HVAC filter.
Dogs and other pets should have some space between themselves and your outdoor air conditioner or heat pump.
Keep the area around the unit free of pet waste, toys, leaves, and other debris. If you have a dog that frequently urinates on the outdoor unit, discourage the behavior. Repeated exposure can contribute to corrosion and damage to the coil and other components.
If you add a small barrier around the equipment, make sure it leaves plenty of room for airflow and technician access.
Pet owners may notice more dust, odors, hair, and dander in their homes. If changing your filter and cleaning regularly aren’t enough, additional indoor air quality equipment may be worth considering.
Depending on your home and HVAC system, options can include upgraded filtration, media air cleaners, or standalone HEPA air cleaners.
An HVAC professional can help determine which options make sense without negatively affecting your system’s airflow.
Pet hair and dust can accumulate in places homeowners can’t easily see or reach. Routine professional maintenance gives your technician an opportunity to inspect the system, check airflow, look for buildup, and identify potential problems before they become bigger repairs.
Regular maintenance is especially important in homes with multiple pets or animals that shed heavily.
Having pets doesn’t have to be hard on your HVAC system. Checking your filter regularly, keeping your home clean, grooming your pets, maintaining clear vents, and scheduling routine HVAC maintenance can help your equipment stay cleaner and operate efficiently.
And while your pets may be responsible for some of the extra fur around the house, we promise not to hold it against them.
