Due to soaring energy costs and a concern for the environment, most every household is feeling the crunch, and has become concerned with home energy efficiency. One great place to begin is with installing a high efficiency furnace to help curb your energy bills.
The U.S. Department of Energy (D.O.E.) has set-forth regulatory standards since the early 1990’s so that manufacturers are held responsible for producing high efficiency furnaces that are regulated to produce 78% of the fuel into direct heat.
The Yellow Sticker
A lot of furnaces are sold with the tagline of “High Efficiency Furnace.” However the D.O.E.’s Annual Fuel Utilization Efficiency (AFUE) rating determines that 78% heat production is considered “mid-efficiency.” An AFUE rating higher than 90% is deemed “high efficiency.”
The yellow sticker that is placed on the side of new high efficiency furnaces is designed to give the basic information about the system and estimated fuel usage with particular standards, and is meant for comparison and guideline recommendations and D.O.E. standards.
You will need to decide whether you need a new furnace or should repair or maintain your existing one. If you are in the market for a new furnace, the rule of thumb is the higher the AFUE rating, the more your high efficiency furnace will save you in the long run. High efficiency furnaces are more expensive, but will end up saving you more in energy costs.
