Although, I'm a Realtor with a mechanical engineering background. So, I can offer a bit of advice. The biggest thing to consider when buying a furnace is the efficiency and the quality (usually the heat exchanger warranty is a good indication).&nbsp;<br/><br/>If you get a furnace with a variable speed motor and multi stage burner it will probably be more efficient. ...but you really need to calculate the payback costs. Sometimes the price difference between a 94%&nbsp;efficient&nbsp;furnace and a 97% efficient furnace will never pay for itself with the savings.<br/><br/>The big question is, what else do you need to do to make the conversion to a modern furnace. Do you need to run natural gas lines into the house? Good luck. Do your research.&nbsp; Sun, 23 Sep 2012 23:21:00 GMT http://www.zillow.com/advice-thread/Need-A-New-Furnace/461045/ 2012-09-23T23:21:00Z We are Realtors, you need ... http://www.zillow.com/advice-thread/Need-A-New-Furnace/461045/ We are Realtors, you need a HVAC contractor to come give you a quote. <br/><br/>Tim Sun, 23 Sep 2012 13:48:00 GMT http://www.zillow.com/advice-thread/Need-A-New-Furnace/461045/ 2012-09-23T13:48:00Z
