Is Fido Sabotaging Your Home’s Comfort? If You’re A Dog Owner, You Should Certainly Read This!


Fido Walking Away from the AC

Man’s best friend, furbaby, and canine companion are all names used to describe our cherished companions. Throughout the years, our loyal friends have been many things: hunters, herders, protectors, and occasionally, accidental saboteurs of cherished and certainly needed household appliances. 


Recently, we’ve been getting calls and finding cases where Fido has been caught red-pawed, providing the family air conditioner an unwanted and unsolicited liquid refreshment. As silly as this is, this isn’t just a quirky anecdote; it’s a potential hit to your pocket and an unintentional act of violence on the very thing that keeps them cool during those sizzling summer months.


Let’s delve into this unexpected and, dare we say, “pee-culiar” phenomenon a little further.


Many dog owners feel their well-behaved pooches deserve a bit of freedom when they open their back door and let their pooch run unsupervised in their backyard. In these moments of free-roaming, snout-to-the-ground exploration, some canines seem to become bedazzled and develop an urge to pee on a very specific target: the condenser coils of your cherished air conditioning unit. Before diving into the “why,” let’s discuss the “oh my.”


Urine, as it turns out, is corrosive. Canine urine contains compounds such as urea, ammonia, and salts that can cause metal to corrode over time (“Canine Urine: Corrosive and Content Analysis”) . When dogs decide to repeatedly mark the coils of an AC unit as their backyard fire hydrant, it can lead to decreased efficiency, potential breakdowns, and costly repairs. The salts and chemicals in urine can cause metal coils to corrode, leading to refrigerant leaks and decreased cooling efficiency. One might say when it comes to a dog’s little bathroom break, the stakes can be pee-tty high.


You may be wondering, “Why the AC unit, of all things?” Dogs have an incredibly developed sense of smell. They are often attracted to the scents left behind by other animals. It’s a theory, yet to be entirely proven, that some dogs might be attracted to the smells of rodents or other small critters that tend to creep around  AC units. They might also just appreciate the warmth, as urine marking is often more about communication and less about relieving themselves (Horowitz). Honestly, what better way to shout, “I was here!” than to leave a mark on a supposedly high-traffic, high-profile appliance?


For homeowners who are now eyeing their AC units (and their dogs) with amusement, suspicion, and dread, fear not. There are some simple steps to keep things in check. See the steps below:

  • Awareness: Know where your dog tends to relieve themselves. A quick check post-walk can save a lot of hassle.
  • Barriers: Consider placing a small fence or protective cover around your AC unit.
  • Training: Positive reinforcement can help guide dogs toward more appropriate pee spots.

While the image of a dog claiming territory over your beloved AC unit can be amusing, the resulting damage is no joking matter. By combining an understanding of canine behavior with a touch of preventative measures, we can ensure our furry friends and household appliances coexist in harmonious, dry peace.
