When your furnace starts to give you trouble, trying to fix it yourself can be tempting. However, in most cases, this is not a good idea. Furnaces are complex machines, and if they are not fixed properly, you could do more damage and cost yourself even more money in the long run. In most cases, it is best to call a professional HVAC technician to look at your furnace and determine the best course of action. So what does a furnace replacement cost?


This article will look at the average cost of a furnace replacement and some factors that can impact the final price.


What Is The Average Cost For Furnace Replacement?


On average, furnace replacement costs between $3,000 and $5,000. High-efficiency furnaces use PVC pipes to vent through walls and have an AFUE rating of 90% to 97%. Mid-efficiency furnaces have an AFUE rating of 80% to 85%. Low-efficiency furnaces have an AFUE rating of 55% to 70%.


Here are some average furnace replacement price breakdowns:

High-efficiency furnace: $3,000 – $5,000

Mid-efficiency furnace: $1,500 – $2,500

Furnace Installation: $950 – $1,150

Maintenance: $100 – $125


What Factors Impact The Final Price?

There are a few different factors that can impact the final price of your furnace replacement. These include:

Furnace Size

When choosing the appropriate furnace, the expert will consider your house’s size, design, and structure. A furnace that is too tiny will not adequately heat your house, while a furnace that is too large may result in issues like short cycling.

Type of Fuel

The type of fuel you use will also impact the cost of your furnace replacement. For example, a natural gas furnace will be more expensive than an electric one. However, the operating costs for a natural gas furnace are typically lower than those for an electric furnace.


Oil and gas furnaces are more desirable in colder areas due to their excellent heating capabilities. The most crucial heating systems are gas furnaces, which need regular maintenance. If you choose to buy a gas furnace, consider the upkeep expenditures. If your gas furnace isn’t properly maintained, you run a higher chance of having deadly gas leaks or furnace fires.

Installation Costs

If your house does not already have ductwork, you will need to factor in the cost of having it installed. It can add several thousand dollars to the final price tag.

Efficiency Ratings

As we mentioned above, furnaces come in different efficiency ratings. The higher the rating, the more expensive the furnace will be. However, you may be able to offset some of the initial cost with energy savings over time.


There are many different furnace brands on the market. Some of the most popular brands include Trane, Rheem, Carrier, and Lennox. In general, name brand furnaces will cost more than less well-known brands.


Furnaces typically come with a warranty of anywhere from five to 20 years. The longer the warranty, the more expensive the furnace will be. However, this is often worth it for its peace of mind.



The cost of a furnace replacement can vary widely depending on many factors. However, on average, you can expect to pay $3000 to $5000 for a high-efficiency furnace. When budgeting for your furnace replacement, consider the installation cost and necessary ductwork. And finally, don’t forget to include the cost of routine maintenance in your budget to keep your furnace running smoothly for years to come.
