Definition of AFUE rating In SBCs

Annualized fuel usage efficiency is referred to as AFUE. The amount of heat produced for every dollar spent is indicated by an AFUE rating. The amount a homeowner should spend on fuel will decrease the higher the AFUE rating of a furnace.

The ideal furnace for them is one with an AFUE rating in the ’90s, as they are the furnaces with the highest fuel efficiency. Just remember that furnaces with this high AFUE rating are frequently among the most costly.

The price of a brand-new furnace

Mid-range new furnace parts range in price from $1,500 to $6,000 (a Rheem furnace with an AFUE rating of 80% costs $1,488 plus installation, for example). If they choose a premium model with a higher AFUE rating, the price could increase by up to $10,000. The installation price is the next thing they should consider; it should be about $2,000 without any reductions.


As a result, any homeowner may consider purchasing a furnace to be a substantial investment. When selecting a furnace to fit heating demands, it’s essential to consider elements like size, efficiency, fuel type, and maintenance requirements. Before making a choice, it’s also advised to evaluate various furnace brands and types and obtain expert guidance from qualified HVAC contractors. Adhering to these recommendations ensures that the chosen furnace will give the house the best possible heating performance, energy efficiency, and overall value.
