Types of Furnaces

Any homeowner looking forward to purchasing a brandy furnace is so lucky to have a wide range of options to choose from. If you’re experiencing freezing weather conditions in your local area, installing a furnace in your home is something mandatory.  In this article, we’ll help you choose between different types of furnaces to determine the most suitable for your home space.

Furnaces have become a trend, especially in American and European homes since no one wants to sit around the fire all evening anymore. All you need to do is switch the furnace on, sit and enjoy the warm air distributed throughout your home. 

Also known as the forced air heating system, a furnace is a central unit for your HVAC system. The furnace is responsible for heating up cold air from the surrounding then distributing it to your home as warm air. 

Furnaces can be categorized in terms of operation, as well as the fuel source they use when heating. Depending on the level of operation, your furnace can be a single-stage, a two-stage, or maybe a variable-speed furnace. Let us take a look at the different furnace types in terms of operation stages. 

Single-stage Furnaces

This type of furnace contains only a single stage of operation i.e. if the furnace is switched on, it can only be switched off again, no extra operation! If a single-stage furnace goes on, it works with one steady and consistent speed. 

One main downside about using this furnace is that you might experience cold spots in your rooms due to the low level of efficiency. This is, however, the most affordable type of furnace and easiest one to install. 


This furnace offers homeowners more operation control over the heating process since you can run it at either half-speed or full-speed configuration. Two-stage furnaces tend to heat the air more efficiently compared to single-stage ones. 

With this furnace, you can at least maintain a certain temperature in your home space. Additionally, this furnace is considered better since it can operate silently.  

Variable Speed

This furnace gives the homeowner the authority to control not only the heat output but also the heating speed. With this heating system, you can easily dictate the temperature of your house thus achieving the desired levels. 

Variable-speed furnaces are considered the most efficient furnace type since it delivers the best indoor air quality. This type of furnace is however the most costly due to its level of efficiency. You should therefore seek a high-efficiency, low operation cost furnace type. 

Types of Furnaces

Now that we’re done classifying types of furnaces using the operation levels, we will go through the furnace types categorized in terms of the source of fuel used to operate the furnace. When it comes to fuel sources, the most used furnaces are gas, electric, and oil furnaces. 

However, some homeowners still use wood, coal, and propane furnaces to heat their homes during the cold months of the year. 

Oil Furnaces

Oil furnaces are mostly used by homeowners living in remote areas and homes where gas sources and gas lines are unavailable. Hereby, homeowners must buy fuel oil tanks to store oil fuel for their furnace. When maintained properly, oil-fueled furnaces are known to last up to twice as long as furnaces fueled by gas. 

One downside about oil tank furnaces is that the price of oil can be seemingly unpredictable. Oil furnaces require regular cleaning and maintenance to get rid of ash and soot building up in.

Gas Furnaces

This is the most popular type of gas used in American homes to provide warm air during the cold winter days. One can get gas fuel for their furnace from the local gas lines. This gas is then transported to their homes into the furnaces where it is used for combustion purposes. 

The gas is ignited and used to heat the heat exchanger which warms the cold air from outside before supplying it to your home. Many people prefer using a gas furnace rather than its alternatives because natural gas is always cheaper than oil and electricity. Gas furnaces are known to be efficient since their AFUE rating is usually above 95%. 

Electric Furnaces

This type of furnace is usually suitable for homeowners who don’t have any access to gas lines or if oil furnaces don’t work well for you. Electric furnaces use electric energy to heat your home during the cold season. 

They are quite affordable in terms of cost but the most expensive of all when compared to the other two options i.e. the oil and gas furnaces. Gas furnaces are usually smaller than other furnaces and less efficient than gas furnaces. 

You can purchase any of the above furnace types for your heating needs or maybe go for a heat pump. Heat pumps can perform the same heating and cooling functions done by other HVAC systems. Heat pumps can be used to heat up your house efficiently and they can work just as well as furnaces and other forced air heating mechanisms. 

Types of Furnaces – Conclusion

When shopping for a furnace, you should know what type of furnace you need for your home heating needs. You have a wide range of options to choose from. Starting from the operating costs to the fuel type used by the furnace, you should decide and choose a specific furnace that will probably serve you efficiently. 

We recommend you to choose from the most used and popular furnace brands since they tend to offer the best product in terms of standards and efficiency. We advise you to take your time when researching types of furnaces to avoid making rushy decisions. 

The furnace you’re about to buy should be able to heat the whole house efficiently and have minimum breakdowns. If you live in freezing cold climatic conditions, we recommend you to purchase a furnace type with high efficiency and low operation costs on the other side.
