Did you know that forced-air heating was first introduced in 1935? At the time, many furnaces used coal for fuel, but it didn't take long for gas furnaces to get introduced. They quickly caught on, since they didn't need to be "stoked" like coal furnaces.

Gas-fired air (HVAC) heating systems are simple and efficient. Since no heat exchanger is required, installation and maintenance costs are reduced. In addition, in this type of HVAC system, there are a minimal amount of carbon monoxide and nitrogen dioxide components present.

Sudden and unusual sounds may indicate that there is a problem with your furnace. Many such sounds are due to slipping fan motor belts or fan parts that need lubrication. A grinding noise may indicate that the blower’s bearings are shot and need to be replaced.

There as basically 2 types of forced air gas furnaces. Packaged systems contain the heating and cooling components within a single unit, whereas split systems keep the heating and cooling units separate, often in different parts of the house.
