Winter is coming, and there’s a chill in the air.  If your home’s furnace is more than 10 years old, there’s a good chance that at least 40% of the energy it consumes is not going toward heating your house.  Compare that to modern gas furnaces that achieve efficiencies of  80-95%.

For those living in colder climates, upgrading to a high efficiency central furnace has never made more sense.   According to Carrier, switching from an old furnace with efficiencies of 55-60% to a high efficiency modern furnace can save you up to $1,000 a year.

To put things in perspective, heating your home accounts for over 50% of total residential energy consumption.  Using numbers provided by the government’s Energy Information Administration, if just 20% of America’s inefficient furnaces were replaced, an amazing 220 trillion BTUs of natural gas would be saved annually.

* Total furnace consumption = 3.6 quadrillion BTUs annually.     3.6 quadrillion x 20% furnace replacements x 30% gained efficiencies = 220 trillion BTUs
