I am in Eastern PA and when our service guy came to do inspection, found hole in heat exchange and rusty burners (4) We are figuring that it doesn't make any sense to put xxxx into 11 yo furnace and probably should get new. got 2 prices from 2 dealers on a Trane XR90. Don't need compressor A/C is fine. after just about deciding to go w/dealer we liked better, made mistake of asking my brother in law his thoughts. he works as a constuction super for a large retail chain. of course, he hates Trane. what now? I know from speaking to the dealers that they will put units from different families, but it isn't their first preference. the dealer we were going to go w/does carry one other brand but I have to call and find out tomorrow. It is going down to 32 tonight and we have no heat anyone put different furnace w/a/c? thanks for any thoughts.
