Best Leaking Drain in Phoenix AZ

Had Penguin in to clean the ducts. They have a little unit they bring into the house that has a spin brush that might reach 8 feet into a run. Probably great for the 3 or 4 ducts right under the furnace. Totally useless for the long run ducts. Dust is much worse since I had them. All it really was a half effort and then an opportunity for the guy to talk about “other services” they could sell. Will never use them again.
