A furnace fact that is worth noting is that they can last for up to 18-25 years if they are well maintained.

How much do you really know about your furnace? If you are like most, it may not be much, and that is okay! Here are some furnace facts that can come in handy at any time.

1. Furnaces are the most common source of heat in homes

It is a well-known fact about furnaces that they are found in almost all American homes. They usually work by sending heated air through air ducts and can be powered by oil, gas, electricity, or a combination.

2. Furnaces can last many years

When it comes to determining how long a furnace will last, there are a lot of things that need to be taken into account. However, a furnace fact that is worth noting is that they can last for up to 18-25 years if they are well maintained.

3. Furnaces have been around for a long time


While furnaces may be thought of as a modern convenience, a furnace fact that is not well known is that these heat-producing tools have been around for centuries. The Roman Empire first used furnaces to heat up public places and homes. Monks also used furnaces to heat the running rivers around their monasteries.

4. Furnaces are made up of three main components

Most homeowners do not realize what parts make up their furnaces. Your furnace is made of three main components; a burner, a heat exchanger, and a blower. Each of these works in combination to produce heat and distribute it throughout the home.

5. Furnace installation is regulated by the government

Both the federal and local governments regulate your furnace’s installation for your safety and protection. It is because of this furnace fact that you have to get your furnace installed by a certified technician.

6. Gas furnaces are the most common

An interesting fact about furnaces is that despite there being several types available, most homes today use gas furnaces. This is because they come with high-efficiency ratings and can be used almost everywhere including rural areas.

7. There are 5 types of gas furnaces

Gas furnaces come in 5 standard types. This includes horizontal gas furnaces, packaged gas furnaces, upflow gas furnaces, downflow gas furnaces, and lowboy gas furnaces.

8. Never store things around the furnace

An often-forgotten or overlooked furnace fact is that you should never store flammable items directly around the furnace. As many homes have their furnaces set up in the basement, which also serves as the storage area, it is important to make sure that the area around the furnace is clear.

9. Read the manufacturer’s warranty or policy

As with many appliances and large purchases, many homeowners do not take the time to go through the warranty or manufacturer’s policy before making a purchase. An unpopular furnace fact is that not every part is covered by the warranty. Because of this, it is important that you familiarize yourself with the warranty policy before buying a furnace.

10. Schedule regular maintenance to protect your furnace

The last of our furnace facts is a reminder of the importance of regular furnace maintenance. Regular maintenance can help you save a lot in terms of repair costs while improving efficiency! It is important to schedule an annual maintenance check, especially if you have had the furnace for over 5 years.
