Dog urine odor is one of the most unpleasant parts of pet ownership. Very strong and pungent, the scent can be difficult to remove. Dogs without proper housebreaking often urinate in the house, and when they go over an air conditioner vent your entire house can quickly fill with offensive odor. Removing dog urine from air conditioner fans takes some effort, but is essential to restoring a clean, fresh scent to your home.
Pull all of the vent covers off the floor and wash them with plenty of hot water and soap. The antibacterial soap will kill off many of the odor-producing agents in the urine and will slow down any bacterial regrowth that might occur. Spread them out on a towel and allow them to fully air dry.

Mix up a solution of 50 percent hot water and 50 percent white vinegar and wipe down the inside of each vent as far as you can reach. Put on your gloves before washing down the vents to prevent the vinegar from drying out your skin. Vinegar is a natural disinfectant and will remove odors without leaving behind harmful fumes.
3
Turn the air conditioner on and pour a small amount of the water and vinegar mix into the vents. The liquid will wash all the way down to the fan and will be blown back up through the vents, reaching areas you could not wash by hand.
4
Mop the floor around the vent holes with the vinegar solution to remove any urine from the area. Scrub the floor well and allow to dry before replacing the vent covers.
5
Stand in front of the air conditioner and spray a generous amount of odor-neutralizing spray into the air intake. The fan will suck up the spray and distribute it throughout the vents, removing any remaining urine odor in your air conditioning system.
Tips & Warnings
Choose the scent of your spray carefully. Many sprays have an overwhelming odor to them, and then you will have to deal with a scent you may not like every time your run your air conditioner.
Make sure your dog is properly housebroken to prevent accidents. Urinating indoors most often happens with young, untrained dogs so teaching the dog where to potty will prevent urine odors in your home.
Never use ammonia or bleach to clean your air conditioner. Both ammonia and bleach release lingering fumes that can be harmful to you and your pets.
