I just found out they intalled a 3.5 ton (that is what is says on the paperwork, the company is double checking records) and it was suppose to be a 2.5. My house is only 1,710 Sq Ft. I don't know anything about a/c but when we were getting quotes all the companies said a 2.5. If this is the case would this cause the problems i have been having?

Thanks Again for the advice..
