Whether it was your friendly feline or a neighbor's, a cat spraying on your central air conditioning unit can fill your home with putrid odors. You may have spent days trying to figure out where the smell is coming from, but now that you know that the air conditioning unit has been marked, you can eliminate it and get back to enjoying the cool air filling your home. Here's how to get rid of that nasty cat spray on the unit.
- An enzyme-based urine cleaning product
- Garden hose with spray nozzle
- Screwdriver and a jar to hold the screws
Prep for Cleaning
The first thing you need to do is disconnect power to the unit. You can do this by flipping the switch on your main breaker panel in your home.
Go to your unit and begin removing the screws that hold the grill on the unit. If the screws are weathered, you may need to use some rust breaking spray to penetrate the rust. Remove the grill and set it aside. Store the screws in a jar until the project is complete so that you don't lose any.
Now that the grill has been removed, you can see the internal components of the unit. This is where the cat spray is stuck and is causing the smell to fill your home as the unit gets warm and pushes air into the home.
Apply a very generous coat of Nature's Miracle to the area. You want to saturate it. As the cleaning solution dries, it will kill the enzymes that are causing the odors. Let the solution dry for a couple of hours. Don't forget to clean the grill with the solution.
After time has passed, return to the unit with your garden hose. Set the nozzle on a low-pressure setting and spray the unit well. This will rinse away the residue, but be careful not to use too much water pressure, or you could knock wiring lose and complicate the situation.
Now, you can replace the grill, restore the power and give the unit a test run. You shouldn't smell the cat spray in your home. If you do, repeat the process or contact your local HVAC technician for assistance.
Prevent Future Sprays
There are a variety of plants that can be planted in the area around the unit to keep cats from coming near it. Check out the list here.
