What Can Pet Hair Do to My Air Conditioner?

We all love our pets. Millions of homes across the country just wouldn’t be the same without the love and companionship that our furry friends can provide us. However, whether you have a cat, dog, rabbit, or other small furry critter, they all have something in common: there’s a good chance they shed their fur, allowing the loose strands to float through the air in your home. These strands can get caught up in the air currents in your home, which often mean they get carried into the intake vent for your central heating and air conditioning system. This is where they can truly do the worst damage.

On this blog, we’ll take a look at why this is such a problem for homeowners and what you can do to reduce the effects it has.


Let’s put this out there: it’s really quite rare for a piece of pet fur to make it through your air conditioner and be recirculated back into your home. Most fur is caught up in your air filter, and that which slips through somehow usually gets caught somewhere in the other components, such as in your blower fan or cooling coil. However, dander can get through much easier and may still find its way back through your home. Pet dander in the air is a huge trigger for allergy symptoms, including sneezing, coughing, watery eyes, and many other well-known and common effects. In some cases, those who suffer from asthma or particularly nasty allergies could even see worse symptoms, such as trouble breathing.

Clogged Air Filters

Pet hair that get sucked into your air intake vent often gets stuck in your HVAC air filter. This is good: that’s exactly what your filter is designed to do. However, pets that shed a lot tend to put a lot of fur into the filter, thus causing it to become dirty far quicker. A dirty air filter can’t process as much air as a clean one, meaning your HVAC system will become less efficient and have to work harder (and thus burn more energy) to keep your home at a comfortable temperature. If you have a furry friend in your home, you should be checking your air filter at least once every two months, and even more if you have a particularly sensitive allergy to airborne pet hair and dander.

Fighting Back

If you’re struggling with a pet dander problem, you probably are wondering what you can do to limit the symptoms you’re experiencing. Fortunately there are a few things you can do. Regular dusting and vacuuming is a great way to take out ton of the pet dander that may have accumulated on the largest exposed surfaces in your home: your floors. They may not appear dusty, but that’s because the constant foot traffic over your floors kicks up the dust and dander and puts it right back into the air. Keeping your floors and furniture clean and dust free can severely limit pet hair and dander symptoms.

Likewise, having your air conditioner and heater properly maintained by a Palm Beach County air conditioning professional can severely limit the amount of pet hair or dander already inside your air conditioner. Air filters are not perfect, and that’s why you need to make sure that your coils are regularly cleaned and your ducts are regularly inspected and cleaned out as well to eliminate any possible dust or dander that may have settled in your system.
