Why Are Gas Furnace Ratings So Important To Understand
There are many different aspects of purchasing a gas furnace that consumers need to understand in order to make sure that they purchase the right furnace for their home. One of these aspects as well as a very important one, concerns the Gas Furnace Ratings that are put on the different models and brands of furnaces that you will find. The AFUE rating of a furnace is the rating that tells you what percentage of money that you spend on energy will be put back into the heat that you use in your home instead of escaping out the furnace flue.
AFUE stands for Annual Fuel Utilization Efficiency. The US Department of Energy passed a law that states all furnaces must meet a specific Gas Furnace Ratings due to the pollution that old furnaces add to the environment. This rating must be over 78 percent AFUE. These Gas Furnace Ratings are not only important because of this new standard but basically because they save us all money. Lennox, Carrier, Goodman, Coleman, York, as well as many other furnace brands have many models that they make available with a very high rating. Carrier has the Infinity 96 Gas Furnace that gives up to a 96.6 percent AFUE rating and in many cases higher.
The Infinity furnace has high rankings on its efficiency, level of noise, and its durability. It carries intelligence technology that helps in communicating with the furnace for troubleshooting, it has a Comfort Heat Technology, an Ideal Humidity System, ComfortFan technology, and the QuieTech noise reduction system. There is also the Coleman Echelon 9.C Modulating Gas Furnace. The Gas Furnace Ratings on these furnaces top out at 98 percent AFUE and above. It holds a modulating design that takes advantage of a one percent firing rate in order to keep the comfort levels throughout the home the same.
The Echelon 9.C has a sister model called the Echelon 8.C which has basically all the same components but has a little smaller rating down to 80 percent AFUE. With these Gas Furnace Ratings, Coleman has earned the Energy Star tag due to their furnace efficiency. Both models have a variable speed blower to reduce the electric consumption that is used as well as the EcoTrak Technology that helps to adjust for living in climates that may be dry, humid, or temperamental. The models numbers that are tagged on these furnaces are determined by their width, MBH input as well as their Nominal CFM. The best Gas Furnace Ratings come from models CP9C120D20MP11A and CP9C100C20MP11A.
