Gas Furnace

Gas Furnaces

Gas furnaces are becoming the most popular furnace option as an alternative to petroleum-based products as well as electric furnaces. Gas furnaces burn natural gas, which consists of methane and other carbon based gases that are often found in petroleum fields. Gas furnaces work by turning on an igniter in the furnace when the thermostat registers below the set temperature. Natural gas flows into the furnaces through pipes provided by the local utility company. An igniter lights the natural gas, which heats air in the furnace. This heat is transferred to the air in the heating ducts, and flows through your home.

Gas Furnace Advantages

Natural gas burns far more cleanly than the oil used in oil furnaces. They are also far more efficient, with an average of 90% AFUE, using less fuel to heat the air. This results in less exhaust and no need for a chimney to vent the heated air and fumes.

Natural gas requires little fuel, and is far cheaper than electricity, possibly making it the most economical option.

Gas Furnace Disadvantages

Natural gas is not available everywhere, so it is not an option for all consumers. Natural gas leaks are dangerous, and furnaces must be well maintained in order to avoid this hazard. Luckily, natural gas has a distinctive odor added to it so that leaks can be detected.

Natural gas is only inexpensive for consumers because so little is used. The actual expenses for extracting, treating, and piping the gas into homes is very expensive.

Gas Furnace Cost

Gas furnaces cost about $1,700-$4,000, depending on the size of the furnace required by your home. High efficiency gas furnaces, with 90%-97% AFUE, can cost $5,000-$7,500. Installation costs can reach an additional $1,000-$2,000 depending on the complexity of the installation.
