Dogs may be man's best friend, but they're not the air conditioner's best friend. In fact, by regularly urinating on the air conditioner condenser (the part of the air conditioner found outside the house), dogs can do damage to the HVAC system in a very real way. Urine can cause the exterior and interior parts of the condenser to rust and deteriorate with time. Follow these tips to prevent your dog's urine from destroying this critical part of your home's climate control system.

Block the Condenser

One of the most effective ways to prevent your dog from peeing on your condenser is to prevent the dog from physically reaching the condenser. From fences to hedges, are a multitude of structures you can place around the condenser that will prevent the dog from reaching it. Keep these tips in mind as you choose the best option for you:

  • The air conditioner repair person needs to be able to reach the condenser, even if your dog can't. A fence or wall with a gate is acceptable, but shrubs are only a viable option if they can be planted in such a way that the dog won't come near the condenser, but the service man can still reach it if need be.
  • Shrubs or walls need to be situated at least 2 feet away from the condenser. This is because the condenser needs air circulation to function properly. Shrubs planted too close to the condenser can cause dead leaves and twigs to build up inside the unit over time.
  • If you choose to plant shrubs around the condenser, you'll need to cut them back regularly, to maintain 2 feet of space between the shrubs and the A/C.

Train the Dog to Pee Elsewhere

While there are many steps to training your dog to pee in a specific location, the basics are pretty simple:

  1. Keep your dog on a leash while he or she pees, and allow him or her to pee only in the desired location.
  2. Reward him or her for peeing in the right spot.

Training your dog to stop an undesirable behavior and develop a more desirable habit can take several weeks. For more details and helpful suggestions, check out this page from the American Society for the Prevention of Cruelty to Animals.

If your dog has been peeing on the condenser, talk to an air conditioner repair person from a company like Springer Bros Air Conditioning-Heating LLC. Ask him or her to come take a look at the condenser. He or she will be able to professionally clean the inside of the unit, and may also have recommendations for repair.
