It’s a dog-eat-dog world for this A/C 🐶. This is what happens when Fido marks his territory on an air conditioner. The acid in the urine discolors the refrigerant piping in front of the coil of the A/C. The result? A complete failure and replacement of the air conditioner. #DogYears #ACYears To protect your pooch ❤️ AND your A/C—Dubson Heating, Air Conditioning & Refrigeration recommends adding a fence around the unit. Please keep in mind it needs to be several feet away from the air conditioner.
