There is a stray cat in my area that loves to go around spraying everything around my house. When I turned my air conditioning on for the first time this summer, I quickly learned that the cat had been spraying my air conditioning unit for a while. About an hour after the unit kicked on, my home filled with a horrid smell of burning cat spray. I immediately shut down the system and called for service. The HVAC technician gave me quite a few tips on how to keep the cat from doing it again and how to clean it up if he does. This blog will tell you what to do if a dog or cat sprays your outdoor air conditioning unit and some other tips for caring for the system.
