Before you begin your search for the proper furnace for your home, you need to know what type of fuel source your home has. It will be one of the following. Which source does
your home use?

AFUE is a measure of how well a furnace or boiler converts the energy in its fuel source to heat over the course of a typically year. It is a ratio of heat output compared to the total energy consumed. The higher the AFUE rating the more efficient the furnace is.
If a furnace or boiler has an AFUE of 90% that means that 90% of the energy in the fuel becomes heat for the home. The other 10% escapes up the home home either up a chimney, and elsewhere. The AFUE does not take into consideration heat losses due to poorly insulated duct system, piping, unsealed windows and the like. As much as 35% of the energy that a furnace produces can be lost when ducts are located in the attic.

The Federal Trade Commission requires new furnaces or boilers to display their AFUE as an aide to consumers in comparing heating efficiencies of various makes and models of appliances.
BTU is a unit of measure used to state the amount of energy that a fuel possess as well as the amount of output of any heat generating device using that fuel. All combustible materials have a BTU rating. For instance, propane has about 15,000 BTUs per pound.
The size of your home, or the area you wish to heat, will determine which BTU Level you will need. If you have a large home, you will need a furnace with high BTU. Here is a handy calculator you can use to calculate the BTU’s your furnace will need for your particular situation. REMEMBER! The BTU number does not represent the heat output. That amount is related to the AFUE percentage.
If you or anyone in your home has even a slight sensitivity to dust or mold, you should consider purchasing a furnace with an air filter or air purifier built in.
