Paul D,
This is DocK’s son. The Trane product line is excellent and backed by outstanding warranties. Personally I would not purchase a XB model because they only have a 5 year warranty on parts and compressor. The XR are better and the XL is the best. Make sure you buy a 410a system. In 2010 all HVAC manufactures are mandated quit producing R22 units. Therefore causing a rapid increase in price on servicing a R22 unit. I also suggest buying a Cleanaffects air filter system. It removes 99.8% of pollen and viruses in the air. Are you looking at a dual fuel system or a heat pump and an air handler? Are you looking for a top of the line system to save on energy or are you looking for an average system that provides a good warranty? There are lots of options, but whatever you do be sure you do some research. I would strongly suggest purchasing a 10 year parts and labor warranty.
Remember…the unit is only good if it is installed and maintained properly. Do research and make sure your contractor knows what he is doing. Talk to other customers and call the Trane distributor in your area and talk to their Feild Service Representative. They will be honest with you and tell you who the good contractors are. If you have any other questions please ask…it is a big investment.
