We don’t know if they had an ancient version of an HVAC tech, riding around on his donkey, but we can tell you that people have been using furnaces or some version of one for a very long time. Back in 1200 B.C. the Romans had hypocausts, or a system of central heat that produced and circulated hot air below the floors of their homes. Also used for warming baths and other public buildings, only the rich were able to afford their cost.

Some excavations in Pakistan have also revealed possible central air heating systems among ancient structures, which would mean their hypocausts were in use about 2,000 years earlier than the Romans. While there were no thermostats, we’re sure couples were undoubtedly bickering over the indoor ambient temperature even then!

Furnaces Are Popular Ways To Heat Your Home

Most houses in the United States are outfitted with a furnace which uses natural gas, the cheapest fuel available. Other energy sources include oil or electricity, or a combination of the three. Ductwork systems are typically utilized, and a whole lot of furnace filters. Made from three main parts, your furnace consists of a burner or heating element, a heat exchanger to divide combustion fuel from breathable air, and finally, a blower that moves breathable air along the ducts. Of course, each furnace has a whole lot of other stuff, including filters, fittings, and more. But these three elements are the most important.

Furnaces Last a Long Time

In a world of expendable goods, it should make any homeowner happy to know that most furnaces last more than 15 years. With regular and effective maintenance, your furnace can even last longer than 20. That’s pretty impressive for machinery your family depends upon day after day, year after year.
