I don’t have much time spent on this site, but I know there are a lot of people with a lot of experience here.
I don’t have all the details, but I’ll try and answer best I can. Here is the situation:
My mother lives in a 55+ free standing house condo community built ~7yrs ago. There are probably 30-40 houses in the complex of varying sizes (some two story and some single story) none bigger than 1700 sq ft. They are all equipped with Goodman 2 Ton HVAC systems. Recently the people that have lived there the longest need to replace their A/C units and every contractor that quotes them says the unit is undersized. One lady in the complex thought something wasn’t quite right so she did some research at the Town Hall and found the units were quoted to have 2.5 Ton systems. She tried to get answers from the town inspector and got a little laugh. She went to the local congressman, and the attorney general, but they told her to contact the condo association. The condo association contacted the GC/builder and he basically laughed and said do what you want; I’m done with that place, try the contractor.
Now what? The builder is ignoring the problem, the contractor says they put in what the builder told them to, the town says they have no liability and these old folks are stuck with failing units that need replacing. Do they have a fighting chance to get this situation remedied? Where would the responsibility fall? It has begun, but where is the best place to begin?
