I live in a condo building, and my HVAC unit is connected to the closed water loop that runs through the coils (for keeping the system cool, I'm told). Over the past 7 years, I have had to replace my Trane unit twice (yes, the entire unit), and I'm pretty certain at this point that it is due to debris in the closed loop water. That being said, the condo board and the building engineer keep saying that the issue is fixed and that they had the towers check/serviced and the water chemicals checked & adjusted (I get that line every year).
I have technicians coming to my apartment regulary to flush out the black water, and then my unit goes back to running normal (less normal each time I have to do this). In fact, some service companies refuse to work in my building because they know what the problem is, and there isn't anything they can do. They also won't give me anything in writing explaining the problem, nor will Trane honor the warranty on their units as a result of this murky water.
Other than a flow regulator that was installed about 9 months after I moved into the unit, everything else about my system is the way it was when the building was built 7 years ago, and I'm told by a couple different service companies that everything is installed properly. So here is where I need some honest advice:
Does the flow/pressure regulator make the water run too slowly, therefor slowing the speed of water in my unit giving the debris/sediment less of a chance to pass through?
Is there some sort of filter I can attach to the closed loop input water line to prevent the gunk from getting in there in the first place?
I seriously am gonna go postal this summer if I can't figure something out (other than moving, which is not an option). Help!
