My Father in Law has a problem with air quality in his home. The home was built in 2001. He lives in Florida, near the west coast. He has two whole house air conditioner units.
All of his silver, in every room, turns black in a few months. This is not simply normal tarnish. It is very dark (black) tarnish with a powdery substance. As a test, we put clean, tarnish free, silver out in his house and also in a neighbor's house. The silver did not turn black in the neighbor's home (built at the same time, by the same builder etc.) but it did turn black in my in-laws home.
The coils in the A/C units also turn black and leak refrigerant. The A/C units were new Carrier units in 9/2001. We replaced one with a Frigidaire 3/2003. We put a new coil in the remaining Carrier in
5/2004. Both units now need new coils. I have never heard of having to replace A/C coils so often.He has had the air tested by the local fire department and they couldn't find anything dangerous but I am not so sure. My Mother in law has had a cough for a long time.
Has anyone had a similar experience? Any ideas on the cause and its source?
Any ideas on what tests he might want to have done?
Any suggestions, ideas or thoughts would be appreciated.
