I think I have been running on borrowed time with my original equipment gas furnace (circa 1960's) and am thinking about having it replaced before it goes TU...although part of me really wants to see how long it will last! It is currently heating about a 1800 sq ft split level house in a moderate (Virginia) climate. Average # of single pane windows and average insulation.
The question is...Are there any problems/scams/etc. I should try to avoid when I start talking to contractors? Is it wise to replace the unit now? Generally speaking, what should I be looking for?
Thanks.
