Let's look at how your home gas Furnace works

Have you ever wondered how your home get heated in the cold winter day? When was the last time you had a Furnace Service in your home? Weather it was a Furnace repair or just having a Furnace Repair Company inspect your Furnace? having a basic understanding of how the gas furnace in your home works will help you understand the importance of your gas furnace in heating your home and the need to have a furnace inspection if you have never had one.

Cold air from inside the house goes through the cold air return duct, into your gas furnace. The heat exchanger inside the furnace burns gas through a gas burner which heats up the air. This heated air is sent back through supply vents back into the house. This heating process by the heat exchanger produces Carbon Monoxide which is a very deadly gas if present in the air. For this reason, it is critical to ensure that there are no cracks or leakage from the heat exchanger. Also Ensure that your home has properly functioning Carbon Monoxide detectors that would alert you to the presence of co2. Hire a Furnace Service Company for a Furnace inspection to ensure that you are not in need of a furnace repair and that your gas furnace is properly functioning. Your gas furnace is controlled by a thermostat, which send signals(voltage) to you furnace to turn on the furnace when the temperature in your house gets below a certain set temperature, and to turn the furnace off when the set temperature is reached.

In most home Central heating Systems, Hot air distribution is done through a supply Plenum that connects to the heat source and which distribute heat to various places in side the home through some connected ducts, that extends to these places within the home. A secondary component called the return Planum draws cool air from various places within the home through various ducts, to the Furnace. This air is then reheated and sent back to through the supply Plenum for delivery to various places inside the home. To increase the air flow and help improve the quality of the air circulated within the home, it is important to occasionally replace the Furnace filter. Cold air moving through the return duct might carry along impurities such as dust, pieces of papers etc. The filter prevents these impurities from entering the blower. If this filter get cluttered with debris and dust, the air flow through the filter will be reduced
