Furnaces create heat by burning fuel (gas, oil, or propane). When the fuel burns, it generates hot gasses which travel through curved metal tubing called a heat exchanger. As air passes over the heat exchanger, it absorbs heat from the hot metal surface. The heated air is then circulated through ducts to warm your home or place of business. Meanwhile, the gasses that are created by the burning fuel are released outside through a vent pipe. Standard furnaces range anywhere from eighty to ninety five percent efficient. An upgrade to any furnace is the two-stage option. Two stage furnaces have the ability to act like two furnaces in one. Once the thermostat calls for heat the furnace will kick on at a lower heat rate for a set period of time, if the furnace does not meet the demand for heat within that time, it will automatically kick into high fire until the heat demand is meet. This helps on mild days when heat is needed but not a large amount saving you money. Also available is the ability to have a variable speed furnace. These furnaces use a dc voltage blower motor which uses much less electric to run. A dc voltage motor can be compared to running a seventy-five watt light bulb, they are capable of running twenty-fours hours a day, allowing you to filter your air non stop.
