ADVANTAGES OF A GAS FURNACE
Natural gas furnaces are reliable.
Piped directly into your home, natural gas is always there when you need it. No need to worry if your oil or propane tank is nearly empty or leaking.
Natural gas furnaces are workhorses. Properly maintained, a natural gas furnace will deliver 20 or more years of service, you can count on a natural gas furnace.
Natural gas is the cleanest-burning fuel, so your natural gas furnace will have a far less impact to the environment than oil, wood, or electricity generated from fossil fuels.
When properly burned, natural gas produces:

- about 30 percent less carbon dioxide than oil and about half that of coal or wood.
- heat, carbon dioxide, and water vapor. Natural gas produces almost no sulfur dioxide, carbon monoxide, dissolved solids, or particulate matter.
Popular models of natural gas furnaces are now 95 to 98 percent efficient and their efficiency is not determined by the climate or outdoor temperature as is true for a heat pump.
A new development in furnace technology is the variable-speed blower, which steadily and efficiently maintains a home’s temperature. The blower motor starts low and, if the set temperature isn’t reached quickly, the motor runs faster until it reaches the desired comfort level. A consistent level of air movement provides better air quality because the furnace runs more air through its filter system.
Modern programmable thermostats provide exceptional control, letting you operate your gas furnace at optimal efficiency.
