Compare Gas Furnace Prices

Gas furnaces are one of the most popular, effective, and cost efficient ways to heat your home during the winter months. Regardless of where you live through the USA, as long as you have access to natural gas or propane gas, you can have a highly efficiency and reasonably priced gas furnace installed at your house at an affordable cost.

Other Types: Oil Furnaces | Electric Furnaces

In this Furnace Price Guide, we’re going to cover both Natural Gas, and furnaces that have been converted to use Propane Gas. We’ll share wholesale and dealer installed gas furnace prices for the equipment from various top rated brands, as well as what cost you may expect to pay for variables like different sized new gas furnaces, higher efficiency, and of course estimated repair costs for gas furnaces. At the end of the page you’ll find a section dedicated to user submitted prices, that contains what readers like yourself paid for their own gas furnace replacement cost, or complete HVAC system.

Prices Sorted by Brand or Manufacturers

The brand or manufacturer of gas furnace you decide to purchase for your home will definitely have an effect on both the wholesale cost, and installed gas (or propane) furnace price. Just like any other HVAC product in the consumer market, there are different levels of quality with gas furnaces. That said, a poorly installed, top rated gas furnace is more likely to fail, than a professionally installed, lower rated furnace. Working with a professional HVAC contractor is just as important as choosing the right furnace brand.

While we focus primarily on natural gas, most can be converted to a propane gas furnace for a very small fee. In most cases, it involves replacing the gas valve, the burners, jets, or a combination of the parts. Depending on your furnace, the kits cost in the $25 – $100 range. As you review the pricing tables below, you can adjust the cost to add in the conversion kit, to get the estimated propane furnace price for your needs.

Setting the Average Home Baseline

In order to display average furnace prices from different brands, we need to set a standard baseline. For this example, we’ll use an 80,000 btu gas furnace with 90% AFUE efficiency, and a 3-ton (1200 cfm) fixed speed blower, being installed in a first floor utility closet, basement, or mechanical room. This setup would be common in an average 1600-2000 square foot home. The “Furnace Only” cost is considered the wholesale pricing, and “New Furnace Installed” is only an estimate of the installed furnace cost, not including any other accessories or a central air unit.

Comparison of Prices Sorted by Gas Furnace Size and the Approximate Area it Heats

When you buy a new gas furnace, it’s very important that you get the properly sized unit for your home. If it’s too big, the gas furnace will short cycle on and off, you’ll end up with inadequate heating and lower the long-term reliability of the furnace. Too small, and it will run all the time, never properly heating your home and wasting quite a bit of energy.

The only accurate way to get a properly sized furnace is to run a heat loss load calculation on your home. You can find do it yourself tools to do it on your own as a reference, or request that your HVAC contractor supply one for you. Many areas of the USA now require an HVAC load test (Called Manual J) to get permits and inspections on the gas furnace installation.

For the purpose of this gas furnace price comparison of different size systems, we are basing the costs on standard (80-90% afue) to high efficiency (92-96% afue) furnaces, installed in a home with normal to average difficulty.

Gas Furnace Size, Heats Approx Area
Furnace (Std-High AFUE)
40,000-60,000 BTU’s, 600-1200 sf $535 – $1,150
$1,710 – $2,450
60,000-80,000 BTU’s, 1000-1600 sf $650 – $1,250
$1,790 – $2,980
80,000-100,000 BTU’s, 1400-2000 sf $850 – $1,748
$2,360 – $3,720
100,000-120,000 BTU’s, 1800-2600 sf $975 – $2,150 $2,560 – $5,100
120,000-140,000 BTU’s, 2400-3400 sf $1,100 – $2,650 $2,920 – $6,610


Cost Comparison of High Efficiency (AFUE) Gas Furnaces VS. Standard Efficiency

If you’ve wondered about the cost difference of a high-efficiency gas furnace versus standard efficiency, the table below will help you understand. When you choose a high efficiency gas furnace, you pay more up front, but save considerably on your monthly utility costs to operate the gas furnace and heat your home. High efficiency gas furnace prices usually include features like variable speed blowers, multi-stage burners, high tech communication with other hvac system components, and much more. Trane and Carrier are leaders in high efficiency furnace models, check the list of Trane furnace prices to get a better idea of the brand cost.

In addition to the initial cost burden, there are also considerations like different venting and condensation drains that must be taken into account by the installers.If not already equipped to handle it, these could add slightly to the cost of installation.

We have used the same average furnace size and home mentioned above. 80k btu, 1200 cfm blower, average installation difficulty.

Furnace Efficiency Rating (AFUE)
Furnace Only

78% – 80% AFUE, Standard Efficiency $450 – $750
90% AFUE, High Efficiency $690 – $1,200
92 – 95% AFUE, Very High Efficiency $850 – $1,650
98% AFUE, Ultra High Efficiency $2,640+ $3,220

Repair Costs with Estimates of Diagnostic, Part Removal and Installation Time.

Fixing a broken gas furnace is a job best left to a qualified HVAC technician. Once you get past return air filters and the thermostat, you will likely need specialized tools and the correct furnace manuals to understand diagnostic codes and troubleshooting procedures for your specific brand of gas furnace.

Most furnace repair companies work from a flat rate repair cost book, or use a factor of parts + labor, to determine the price you pay for gas furnace repair. There are good and bad about both pricing methods, and the industry mix is relatively equally split. The gas furnace parts only cost is based on what you could buy the part for yourself, if you were to handle all troubleshooting, track down the part, and complete the repair 100% on your own. The install time is based on the approximate time it would take a professionally trained technician to diagnosis, remove & replace, and confirm the gas furnace being in good working condition. The total cost of parts installed in the third column, includes all parts and labor, including the service call cost.

Note: If your gas furnace is more than 8-10 years old, or the total cost of the service call and your gas furnace repair is more than $750, you should always ask for a full replacement estimate, and always get a second opinion if you have the ability to do so.
