Introduction
Furnaces are what are used to heat homes and buildings. There are various types of them, such as single-stage, two-stage, and variable-stage. They can be powered by electricity, gas, or oil. The furnace warms up the air and then the blower motor circulates it through ducts and vents to make each corner of the house warm. The hot air goes through the heat exchanger which gets rid of the combustion gases and sends them outside with a flue.
Furnaces consist of many parts, for example, a gas valve, burner, circulator pump, thermostat, filter, heat exchanger, blower motor blades, and air handler. All of these parts work together to give heat in cold weather. There is the AFUE rating which is used to figure out how efficient the furnace is. The higher the rating, the lower your utility bills will be.
Homeowners should maintain their furnaces regularly. This is important for performance and safety. The data sticker on the furnace has details like its make and model number. This helps technicians choose the right parts when repairs are needed.
Don’t forget about keeping your heating system in good shape this year! If you don’t, it could cost you a lot or even cause a shutdown during winter. Contact an HVAC expert now! Don’t let the wrong furnace be one of your 99 problems!
