“Calculate ‘paybacks’ before buying furnace

Good reminder from Inman News regarding the importance of whole home energy efficiency when considering purchasing a new furnace. I’m not positive the link will work; here is a tidbit:

“How efficient any heating system is going to be at keeping your home warm is dictated by how energy efficient the home is in the first place…So before you consider your new heating system, if possible you should complete any required energy upgrades your home needs. Your best bet is to have an energy audit done.” 

Anyone have any energy auditors they’ve liked and wish to share?http://www.inman.com/buyers-sellers/columnists/paulbianchina/calculate-paybacks-buying-furnace
