The furnace is a fascinating tool, really. A furnace is an essential part of a modern home, in areas that have low temperatures. Furnaces are amazing and resilient appliance, and marvels of modern technology. There are, however, a few things you may not know about them.
Did You Know This About Your Furnace?
One: furnace installations are regulated by your local and federal government. Given the dangers surrounding the installation, as well as the fire hazard of a faulty burner, these installations require regulation. Any HVAC contractor is required to be licensed, and is required to get a permit when replacing your system or installing a new one. Building departments require a qualified third party to inspect the installation after it is complete, to make sure that the HVAC system is performing as it was intended to perform.
Two: a furnace can live for as long as 25 years. And a high-efficiency furnace has a shorter lifespan than a regular-efficiency furnace, which comes as a surprise to many people. High-efficiency ones generally live 15-20 years, which typical furnaces live 18-25 years on average. Ensuring a long life for your furnace means having preventative maintenance, however. Without occasional inspections, the average furnace will not live to its full potential lifespan.
Three: much like an insect (head, thorax, and abdomen), a furnace is comprised of three parts. First is either a heating element or a burner; gas furnaces have burners, while electric furnaces have heating elements. Gas furnaces are more common, but there are plenty of electric furnaces in the world as well. The second part is the heat exchanger, which separates the combustion gas from the breathable air. The third and final part, the blower, sends the breathable air (which is conditioned) into the different rooms in the house, through the system of ducts throughout the building.
