Electric Furnace
The cost to replace an electric furnace is between $1,700 and $6,750.
The average cost to replace an electric furnace is $4,445.
In grids served by coal-fueled power plants, electric furnaces demand the burning of more coalpoor for the environment.

Natural gas furnaces are easy to maintain and fairly clean burning, though not as clean as electric models.
The average cost to replace a propane furnace is $5,270.
Many gas furnaces can be converted to propane with an inexpensive kit.
Propane furnaces are highly efficient, with AFUE ratings ranging from 90% to 98.5%.
Oil furnaces are mainly found in colder climates, often in the northeast U.S. and Canada.
Heating oil is trucked to the home and is piped into exterior tanks that are buried underground.
Oil furnaces are moderately energy-efficient, returning AFUE ratings between 80 and 90%.
Many older homes already have buried oil tanks.
If these tanks are in good shape, they can be used for oil furnaces.
Furnaces in this class will heat homes up to 1,200 square-feet.
Furnaces in this medium-size class will heat homes up to 2,000 square feet.
Furnaces in this class cost from $3,000 to $4,500 to replace.
An average replacement cost is $3,750.
Furnaces in this class will heat homes up to 2,100 square feet.
A key indicator of afurnace’s efficiencyis Annual Fuel Utilization Efficiency (AFUE).
AFUE is expressed in terms of a percentage.
Higher percentages mean a moreenergy-efficient furnace.
The U.S. federal government mandates that new furnaces should meet or exceed 80-percent AFUE.
Single-stage furnaces are the cheapest.
To move to a two-stage furnace will add a few hundred dollars to the cost.
Upgrading from a non-variable speed furnace to a variable speed furnace will cost from $500-$800 more.
Furnaceshave single, double, or modulating stages of heat.
For one or single-stage heat, the furnace will turn on or off.
Furnacestages can be compared to lamps.
One-stage furnaces are like a lamp that can be turned either on or off.
Two-stage furnaces are like a light that has a low and a high setting, in addition to off.
Modulating furnaces are like lights with dimmer switches that can be gradually brightened or dimmed.
Furnaces costso much because they are large, long-term investments, with costs that are spread out over time.
The replacement of a new furnace may be covered if the system has failed within the limited warranty period.
A home warranty plandifferent from the furnace warrantymay cover the replacement of a furnace.
