How Much Does a New Furnace Cost?

The cost of a new furnace can be anywhere from around $2,000 to over $10,000, but it can vary widely based on a variety of factors, including the brand, fuel source, efficiency rating, the size of your home, cost of living prices in your area, and installation costs.

Keep in mind that investing more upfront in an energy-efficient model can save you money on monthly utility bills over the lifespan of your furnace—and you may be eligible for certain tax credits and breaks.

So, while there is no easy answer to the question, “How much does a new furnace or furnace replacement cost,” you will probably end up spending thousands of dollars for a new unit.

Average Cost Of A New Furnace in the US

The average cost of a new furnace is $3,500. While electric furnaces cost less upfront, you will end up paying more for your energy usage. Gas furnaces tend to offer the best balance between initial cost and energy pricing for a solution that offers long-term savings over other options.

A New Furnace in St Louis is Less Than The National Average

One of the major costs associated with purchasing a furnace replacement is installation costs. You will need to hire an experienced HVAC professional to make sure that everything is set up properly. Fortunately for St. Louis residents, the cost to install a furnace is less than the national average. St. Louis homeowners don’t have to pay the same installation fees as homeowners in other parts of the country for the same furnace.

Electric Furnace Cost vs. Natural Gas Furnace Cost

Gas furnaces tend to cost more upfront because they require a more complicated installation process in order to address carbon monoxide safety issues. Electric furnaces are less expensive and easier to install, but you will end up paying higher fuel costs while also sacrificing a certain amount of comfort.

Natural Gas Furnace Prices

The national average price range for a gas furnace is around $3,000 to $15,000. Remember those are national averages (the St Louis market is often less expensive), and that most of the cost goes towards installation. If you live in a colder climate and want to save on monthly fuel costs, a furnace connected to a gas line may be the most cost-effective and efficient option.

Electric Furnace Prices

While electric furnace prices tend to be lower than gas furnaces, there are some potential drawbacks to be aware of. While electric furnaces are cheaper to install, they aren’t quite as efficient and come with higher fuel costs. For these reasons, they are best suited for people in warmer locations where there is less demand for the furnace.

Factors That Determine Furnace Cost

The total cost of a furnace is determined by a variety of factors. In some cases, installation can be complicated by the location of the furnace, how much ductwork is required for proper installation, and the type of fuel the furnace uses.

Your installation professional will be able to evaluate your home and offer a detailed heating installation estimate so that you don’t have to worry about hidden costs. The brand, size, and efficiency rating of the furnace will also affect pricing, so be sure to shop around and find the right products to fit your home and your budget.

1. Type of Furnace Brand You Choose

Whether you are on a budget or you are willing to pay top dollar for an energy-efficient model that comes with an extensive warranty and excellent customer support, there is a furnace brand and model on the market to fit your needs. Some major brands include American Standard, Bryant, Carrier, Lennox, Rheem, and Trane.

As you shop around, look for brands that offer models that fit your budget, offer energy efficiency, and can adequately heat the entire square footage of your home.

2. Special Features and Efficiency of the Furnace You Choose

Some furnace types have special features that may have additional costs; for example, variable speed options related to the blower motor can increase cost but, in turn, increase your comfort. A high efficiency model may also cost more but offer significant benefits in the future.

  • High-Efficiency Furnace vs. Standard Efficiency Furnace: The difference between high-efficiency furnaces versus standard efficiency furnaces comes down to how much fuel is actually converted into heat. With a standard efficiency model, about 80% of gas is directly converted into heat. A high-efficiency model can turn 90-98% of gas into heat, which means that you save on energy costs. Many modern, high-efficiency gas furnaces can reach a rating of up to 98.5% Annual Fuel Utilization Efficiency (AFUE), making them the cheapest to run and great for homeowners who live in cold climates.

3. Furnace Size You Need

The size of a furnace is measured in British thermal units (Btu), which determines the amount of space it is thus able to heat. For example, a 700 to 1,500 square foot home may need a 40,000 to 80,000 BTU furnace.

It is vital that you find the right furnace size for the house. If you purchase a unit that is too small, you will have to constantly be going to turn up the thermostat because your home won’t be comfortably heated, you will pay more for energy, and your furnace will wear out faster. The right size furnace will allow you to enjoy a comfortable indoor environment and save on utility bills.

4. Furnace Installation Labor Cost

Outside of the price of the actual equipment, labor costs are often a primary factor in determining new furnace installation. Do not try to DIY any part of the furnace installation process as it could end up causing more damage than intended. Leave it to the professionals.

When it comes to quality labor, you tend to get what you pay for.  However, Superior Service takes pride in providing experienced, quality work at fair prices.

If you encounter a cheap furnace installation bid, we recommend asking questions in order to help determine the experience and knowledge of the installers.

5. Furnace Location in the Home

Furnace installation costs can be significantly impacted by where the furnace is located in the home. If installers have to crawl under the house and/or work in cramped spaces with poor lighting, the entire installation process will take longer. The easier the furnace is to access, the more you will save on installation.

6. Whether or Not You Need New or Additional Ductwork

Replacing an old unit may require new and additional ductwork. There may also be sections of the old ductwork that are damaged and causing leaks that make your entire home less energy efficient. The amount of work required to get your furnace ductwork up to working standards and fitted to your new furnace will help determine installation costs.
