Gas Furnace Repair and Installation
Set The Bar Higher For Your Furnace
You have high expectations of your furnace. So do we. Higher AFUE ratings means better, more efficient Gas Furnaces.
The efficiency of gas furnaces have improved over the years with the use of cleaner, safer equipment and standards. ENERGY STAR standards have significantly changed how manufacturers engineer heating and air conditioning equipment. According to ENERGY STAR reports, if every gas furnace sold in the U.S. met the current ENERGY STAR requirements, annual savings on energy costs would increase to about $171 million.
Also, the amount of greenhouse gas emissions would be reduced to equal the amount of those produced from about 177,000 automobiles. Gas furnaces are up to 98% efficient on the AFUE (Annual Fuel Utilization Efficiency) rating scale. That means that 98% of the gas fuel is being converted to heat and only 2% is being lost in the chimney.
How It Works
The typical gas furnace is fueled by either liquid propane or natural gas. In modern gas furnaces, there are two intake valves that bring air into the system. A draft inducer fan motor sucks air into the burner assembly to supply oxygen for the fuel that is to be produced by a spark igniter.
A spark ignites the gas and oxygen keeps it burning at a high temperature. The burner assembly heats a set of pipes called a heat exchanger. The oxygen used to produce the flame is expelled through either a flue or through a pipe leading outside of the home to exhaust carbon monoxide or other fumes. A second air intake system uses a blower fan to draw air through a return vent and blow it across the heat exchanger and is pushed back through the air ducts to heat the rooms.
Benefits of Gas Furnaces
Gas furnaces are still one of the most popular used heating equipment in the U.S. today, especially in the Northeast. There are a few benefits they have over other heating systems, including:
- Natural gas is more energy efficient than oil, saving homeowners hundreds of dollars annually.
- The fuel burns more cleanly and quickly than compared to oil, which means fewer air pollutants are exhausted into the air.
- Gas furnaces require less fuel while heat output is very high.
