Dale Brenner

Air systems tech

Dale Brenner has worked on air systems for 20 years. Ducts, returns, filters, the whole path air takes through a house. He has been called out to more dog homes than he can count.

He has worked in homes with one small terrier and homes with three big shepherds, and he gets asked the same question in every one of them: why does the house still smell after the carpets get cleaned?

He contributes to Dog Mom Tips on how air moves in a dog home and what actually clears it.

“The pet smell does not come from your dog. It comes from your floors. Dog urine soaks in over the years, bacteria break it down, and the result is ammonia gas. It rises out of the carpet every day. Cleaning the surface does nothing. You need to pull the gas out of the air.”
