I’m a fairly new tech (1 year Exp) looking for tips.
On one of my routs theirs a couple of multi floor level shopping malls. Most of them contain water source heap pumps in the T- Bar ceiling. I have found several coils absolutely dirty. Some of them are even starting to freeze up. Obviously I can’t pressure wash them inside the store, so what I have been doing is using some of those EPA approved foam spray cans and at least on the surface they seem to be working great.
My question is how good do they work or is there some else out there that could do a better clean up all the way through the coil.
Just trying to follow that saying……….. “Always leave it better than you found it”
Thanks for time
