This is our Top Rated Gas Furnaces 2011 Guide in which we share the best gas furnaces currently available in 3 different efficiency categories. Part of our purpose at WebHVAC.com is to provide our readers with quality reviews and information so that they can choose a furnace that makes the most sense for their home and family. An educated consumer is more likely to make a choice that he or she is satisfied with in the years to come.
This guide will help you match your needs to the best gas furnaces available. If you live in a warm climate and don’t rely heavily on your furnace, a standard-efficiency model may serve your purposes. If you live in a cold climate, then a high-efficiency model will pay for itself in 3-6 years by lowering energy bills. If you enjoy precise climate control when heating or running an attached air conditioner, then a variable-speed blower is essential. Also keep in mind your budget and the length of time you plan to live in the home when making your purchasing decision. These are the factors that will help you select the gas furnace for you. This Top Rated Gas Furnaces 2011 Guide will point you in the right direction.
Standard Efficiency Furnaces: 80% AFUE
High Efficiency Furnaces: 90% to 95% AFUE
Very High Efficiency Furnaces: Above 95% AFUE
AFUE stands for Annualized Fuel Efficiency and gives the percentage of created heat that actually goes into your home. An 80% AFUE furnace will lose 20% of its heat out the flue; a 95% AFUE furnace will lose just 5%. Prices tend to follow the AFUE rating, with the most efficient furnaces costing the most, primarily because they have a secondary heat exchanger to capture more heat. Keep in mind, of course, that the higher the efficiency, the lower your energy costs will be.
