The 5 Biggest Factors That Affect The Price Of A Furnace

It’s that time of year again. Days are getting shorter and the weather is turning colder. For most homeowners, it’s time to bid the air conditioner goodbye and start using the furnace.

Unfortunately, for some, it may be the time you are realizing you need to buy a new furnace. If your furnace is old, or not working properly, or incurring a lot of repairs, it may be time to purchase a new one. With all the different options out there, how do homeowners know how much to spend?

Here’s what affects the price of a furnace and how to get the most out of your new furnace!


Just like anything else, different brands of furnaces have different prices and with such comes differing levels of quality. Homeowners should look for features and efficiency that different brands offer when shopping for a new furnace.


The size of the furnace matters, and affects the price, as well. Larger furnaces tend to cost more, and vice versa. However, you must purchase the right size furnace to ensure your home is heated in a cost efficient manner.

Contractors use the Manual J method to size the equipment for your home. This method involves calculating the capacity of a furnace to put out heat compared to its electrical input based on your home’s size, window efficiency and other factors. Bigger isn’t necessarily better. If the system is sized correctly, it will save you money in the long run. If you buy the wrong size, your system will be working too hard which will impact your bills, the overall efficiency and life of your unit.

Sizing is a very important factor when purchasing a furnace!

Every furnace will come with different features, and these affect the price. A basic model will be cheaper, and more advanced models with higher efficiency and elaborate features will cost more.

Features on a furnace may include variable-speed blowers, which allow the furnace to run at high speed in cold weather and low speed in mild weather. Variable speed blowers help save energy by making the furnace more efficient, as well as reducing wear and tear on the furnace by letting it adjust to temperature. Other features may include a two-stage gas valve or a quiet combustion technology. A good rule of thumb is the more features on a unit, the more efficiently it will run and the more cost effective it will be.

Purchasing a programmable thermostat for your furnace also helps to save energy, as well as wear and tear. When purchasing a furnace, homeowners should first research all available features and accessories to decide what will work best for them, or call one of our HVAC experts (888-978-2717) to help you figure it out!


Furnace efficiency — measured by Annual Fuel Utilization Efficiency (AFUE) — is a measurement of how much of the energy put into a furnace is converted into heating power for your home. For example, when you buy a furnace with 92 percent AFUE, for every dollar you spend, 92 cents goes into heating your home and 8 cents is wasted.

While a furnace with a higher efficiency rating will have a higher initial price tag, it may end up saving you money down the line. This is because higher-efficiency furnaces use advanced features that lead to a higher price tag, but save money in the long run by keeping energy costs low.

We recommend going with the most efficient furnace you can afford in order to keep monthly energy costs low in the future.


Although this won’t affect the initial list price of a furnace, homeowners should consider costs associated with installation, as well. It’s important to select a reputable, highly trained contractor who will correctly install the furnace.

Homeowners who skimp on quality installations, using installers who fail to follow standard practice, such as ignoring factors like airflow rates and sealing ducts, will pay the price later in increased energy costs.

There are many factors affecting the price of a furnace, when buying one, you should decide what’s important to you. If you’re looking to spend as little money as possible, look for a budget model that may have fewer features. If being green is important to you, you may have to spend more on an energy efficient model.

Either way, a furnace is an investment. A good, well-maintained furnace should heat your home for fifteen to twenty years, so keep that in mind when making a purchase.
