My Animals Urinated in My Duct System Again! What Can I Do?
Pet Urine is difficult to locate in any home, even though it is very easy to smell. Pet urine can be removed out of your duct work. To determine where your pet has urinated, provide yourself with a UV black light. Make sure you turn all the lights off on that floor, so that you can be sure to see the glow.
Once you detect the area(s) where the pet has urinated, you must clean that area in its entirety. Most times animals will go to the bathroom on carpet or hardwood floors, which can be located close to your duct system. Once an animal has urinated in one spot then it is very instinctive that they keep re-soiling that specific area.
To remove the odor, it is highly NOT-RECOMMENDED to use any products that are ammonia based. As you know, if you have this problem, most urine has ammonia in it, which does not effectively clean the soiled area, and will keep the animal still interested to keep re-soiling this spot. We do recommend the use of baking soda with white vinegar. Please always do a test spot first to ensure that it does not create more damage, by discoloring your carpets or hardwood floors. Make sure that these products do not enter your heating and cooling system. If any of the products do enter the duct system, you should open all the windows and doors and call us.
Once the surrounding areas around the vents are cleaned, you will need to hire a professional duct cleaner. Dust, debris, crevices, or cracks can hold in the pet urine odor. Once your system is running it will distribute this awful smell throughout the home. At City Duct Cleaning we have the proper chemicals that can remove the urine smell from inside the ductwork, without contaminating the rest of your system.
We have a long-time customer who had a kitten that took a liking to urinating directly over one particular air vent in her home.
The heat from the furnace would dry it out and spread the stink throughout the entire floor that vent was serving.
It was necessary to replace the metal boot and the first pipe leading into it. Due to the nature of normal ductwork installations, where one pipe goes into the next one to enhance proper air flow, there was a gap where the two fittings connected that could not be reached to be cleaned. So we replaced those two parts and the air vent even though it was necessary to put a hole in the drywall directly below that air vent.
We also encapsulated the entire duct system, paying closer attention to that duct run. Our chemical also happens to work perfectly on drywall, concrete and wood, so while we had the space open we also sealed all around the area where the vent was (between the floor and the ceiling below). This procedure solved the problem with the odor completely.
It is not clear how she was able to get her kitten to stop peeing in the vent.
