The Complete Guide to Purchasing a Furnace: Everything to Know

Projections show that the US residential furnace market will reach a size of $12.9 billion by the end of 2031.

If your home gets a bit cold, a furnace can be the perfect solution. There are various options, so you should be able to find something that’s perfect. Before purchasing a furnace, however, there are various factors you need to consider.

In this guide, we’ll go over what you need to know to find the furnace that’s right for your home. Keep reading for more.

Types of Furnaces

There are four main types of furnaces available. Electric furnaces are the cheapest, as well as the easiest to install and maintain. They are, however, the most costly to run.

A gas heater like the Propex hs2000 is more cost-effective to operate but can be harder to install. You’ll need a flue for the exhaust fumes to leave your home, and this should be inspected at least once a year.

Oil furnaces are fairly similar to gas furnaces. The main difference (aside from the type of fuel used) is that they require an oil tank. This will often be buried somewhere near the property.

Propane furnaces are also similar to gas furnaces, but a flue isn’t needed. Instead, you can install a small vent on an exterior wall beside the furnace.


You need to think about the cost of the furnace as well as the installation. Electric furnaces are typically less expensive than other types, but the price can vary a lot depending on the model of the furnace, its size, and the labor required to install it. You should set a budget at the start so that you can make a suitable choice when comparing furnace costs.


Reading online reviews is a great way to find reliable furnaces and brands. You should look for something that’s going to last so that you don’t have to replace it too soon. Routine maintenance will also help maximize the lifespan of any furnace, so it shouldn’t be ignored.

Additional Features

While most options will have all the essential furnace features, there are other features that you may want to think about. A variable-speed blower can provide better airflow to heat your home more evenly. Multi-stage operation is another feature that will automatically adjust the heat to match external conditions, keeping things comfortable while saving energy.


Routine furnace maintenance is key to keep yours running. For example, the manufacturer’s instructions will tell you how often you should change the air filter (typically once a month). It’s also a good idea to have a qualified professional perform an annual furnace service so that it keeps operating at maximum efficiency for as long as possible.

Purchasing a Furnace

All of these things should be considered before purchasing a furnace. Think about your home and your needs, then compare the different options you have that are within your budget.
