I will apologize in advance for any protocol errors in posting, I truly have never done this before.
Yesterday my children came to me and told me there was a funny smell upstairs and a wet spot on the ceiling. I went upstairs to look and although I did not smell any odor I did indeed see a wet spot on the ceiling. In addition, the flooring under the a/c vent was damp and the unit was not blowing any cool air. I checked the emergency drip line to the outside of the house (forgive me if the term is incorrect) and it was not emitting any condensation, so I opened the attic access and went up. Once inside the attic I could not see any water in the pan or around the unit.
I have two units that cool my home, both are Trane with the compressors being outside and the a/c' s located within the attic. The unit in question is Model 2TTR2048A1000AA; S.N. 24044S31F
Today an A/C Contractor came to the house and told me that this particular unit was a faulty design by Trane and while the idea was great at the time, practical application didn't work. He then told me the coil was "sizzling" and would need to be replaced. As I asked him for specifics on the replacement he told me he couldn't even obtain replacement parts for this unit anymore so the only option would be replacing the condenser (even though he verified the condenser was working?) the coil and the plenum. The bottom line was so outlandish that I asked why not just replace the entire works. At this he stated that perhaps he could locate the parts. At this juncture I concluded the conversation and the visit came to an end.
The problem I have is multi-layered. I do not posess the technical knowledge needed to ascertain the validity of the information being given. Having recently lost my husband and being alone with three children may seem like an opportunity to "over-fix" for some. Good information regarding A/C units is not easily obtained.
I would greatly appreciate any information and/or direction you could provide me.
