The cost of a new Carrier furnace installation in an average home is usually between $3,000 and $7,000, but the range may be as low as about $2,400 and as high as $8,000 or more on high-end systems. The broad range of prices boils down to such aspects as the BTU heating capacity of the furnace, its efficiency and stage (single-stage, two-stage, and modulating), and the series or model of Carrier to select.
Overall, the bigger furnaces that produce more heat, more sophisticated multi-stage burners, and the best Infinity series features are at the high-end of the price range, whereas the simplest smaller units of the Comfort series are the cheapest.
Cost Overview by BTU Capacity
The size of a furnace is in BTUs (British Thermal Units) per hour, which means the amount of heat it produces. The more BTU furnaces (required in larger or ill-insulated houses) are more expensive to buy and install as well.
As an example, a 60,000 BTU Carrier gas furnace may be installed at approximately $1,900 to 4,900, and a 100,000 BTU unit at approximately $2,300 to 5,500. This is because larger furnaces consume more material and are usually more complicated to install, thus the higher the capacity, the higher the cost. The BTU is also important to choose, an HVAC expert will calculate the size of the furnace depending on the square footage of your home and the climate to make sure that you are neither under- nor over-powered.
To give an example, a typical 2,000 sq. ft. house in the United States may require a furnace of about 80,000 BTU, which is in the middle of the price range in the table below.
| Furnace Size (BTU) | Typical Installed Cost |
|---|---|
| 60,000 BTU | $1,900 – $4,900 |
| 70,000 BTU | $2,000 – $5,000 |
| 80,000 BTU | $2,100 – $5,200 |
| 90,000 BTU | $2,200 – $5,400 |
| 100,000 BTU | $2,300 – $5,500 |
Cost Overview by Furnace Stage
Staging of a furnace such as single-stage, two-stage or modulating has a significant influence on the price. The least expensive are Basic Single-stage furnaces (one heat output level) followed by Two-stage furnaces (high and low heat settings) and Modulating furnaces (continuously variable output) which are more expensive because of their advanced technology and comfort advantages.
The entry-level models offered by Carrier are single-stage and are cheaper, but the best models have modulating gas valves and variable-speed blowers that increase comfort and efficiency at a higher price.
To take one example, the entry-level Comfort series (all single-stage) of Carrier averages about $2,400 to $6,200 installed, and the top-of-the-line Infinity series (with modulating burners and Greenspeed intelligence) is about $3,200 to $8,000 installed. The two-stage heating mid-range Performance line is in the middle.
Practically, the cost of going to a two-stage furnace instead of a single-stage furnace may cost an additional $500-1000 to the cost of the equipment and going to a fully modulating furnace may cost an additional $500-1500 on top of that. The multi-stage furnaces are more expensive to purchase due to their advanced burners and controls, but they are more consistent in temperature and fuel efficient.
| Furnace Type | Features | Typical Installed Cost |
|---|---|---|
| Single-Stage | One heating output (100% capacity only) | $3,000 – $5,000 (lowest cost) |
| Two-Stage | High and low fire settings | $4,000 – $6,000 (mid-range cost) |
| Modulating | Continuously variable output | $5,000 – $8,000+ (highest cost) |
A single-stage furnace (either off or on full blast) is usually the least expensive to install as indicated in the table. Moving to a two-stage model is more expensive due to new parts such as a two-stage gas valve and more complicated controls.

Modulating furnace is the most costly but most comfortable and efficient type of furnace as it has the ability to change its flame in small steps to give you the heating that you need. Modulating technology is expensive to homeowners, but it can reduce the fluctuations in temperature and save fuel in the long run. It is a worthwhile investment to many in colder climates or long-term energy savings.
Cost Overview by Carrier Series
Carrier produces three primary lines of gas furnaces, including the Comfort, Performance, and Infinity lines. Each of the series is associated with another price and features level. The entry-level furnaces are comfort series furnaces which are typically single stage furnaces with standard efficiency (80 to mid-90 AFUE) and less complex design.
The middle-tier is filled with performance series furnaces which provide more efficient models and two-stage heating to control comfort. The Infinity series furnaces are the best products of Carrier and have the highest efficiencies (up to ~98.5% AFUE), modulating burners, and smart communicating controls to provide the best comfort. Of course, the furnace prices also follow this hierarchy: Comfort is the cheapest, Infinity is the most expensive, and Performance is the middle one.
The following is a summary of average cost ranges of each Carrier series with full installation. As indicated, Comfort series models are averagely in the mid-$ thousands, but Infinity models can reach or even surpass the upper limit of the range because of their high technology.
It should be mentioned that more expensive Carrier models are more fuel-efficient, which will save your money in the long term – the more expensive Infinity furnace can be partially compensated by the reduced heating costs during the life of the furnace.
| Carrier Series | Efficiency (AFUE) | Installed Cost Range |
|---|---|---|
| Comfort Series | 80% – 95% | $2,400 – $6,200 |
| Performance Series | 80% – 96.5% | $2,800 – $7,200 |
| Infinity Series | 80% – 98.5% | $3,200 – $8,000 |
The installation of a Comfort series furnace could be as low as $2,500 – $4,500 on a basic 80 percent model, or up to $5,000 or more on a high efficiency Comfort (95 percent+ AFUE). The mid-range (approximately 4,000 to 6,000 dollars on most installations) is represented by performance series units, which have such features as two-stage burners and ECM blower motors.The Infinity series has the highest prices, typically at least $5,000, and especially the flagship modulating models. As an example, the Infinity 98 Greenspeed modulating furnace is one of the most expensive furnaces that Carrier offers, and it can cost close to 8k with the installation. Customers are actually paying more to have more efficiency and comfort options: the Infinity models are the most efficient and comfortable in terms of fuel savings and home comfort, but the Comfort series is the most basic and reliable heat at the lowest initial cost.
Cost Overview by Popular Carrier Models
Lastly, we shall examine some of the Carrier furnace models in the three series and their average prices. The table below lists some of the most popular models (some of them belong to the Infinity, Performance, and Comfort lines) and their efficiency levels and average installed cost range (national U.S. averages in 2024-2025).
The prices are all inclusive of the furnace unit, standard labor and materials. Prices may change depending on the local labor rates, the specific size (BTU) of furnace selected and any other work (such as new ductwork or venting).

| Comfort 80 (58SB0) | 80.0% | Single-Stage | $3,600 –$4,900 |
The cheapest ones are the Performance 80 furnaces which are simple 80 percent AFUE furnaces that can cost less than 3,500 installed as shown. At the high end, there is the Infinity 98 (Greenspeed) modulating furnace that can cost anywhere between approximately 7,000 dollars to 9,500 dollars installed.
The Infinity 96 and 97 (both high-efficiency two-stage furnaces) are a bit less expensive than the Greenspeed, but still quite high-end, and will be in the mid-$5,000s to low-$6,000s installed. The Performance series is crowned by the Performance 97, a 97 percent AFUE two-stage furnace that typically costs in the mid-$5,000s installed, a good high-efficiency choice that does not require the extra features of the Infinity. Performance 96 models (approximately 4,000 5,500) and the Performance 80 models (2,400 3,500) are economically minded options within their efficiency groups.
The Comfort 96 (59SC6) is an entry level condensing furnace (~96% AFUE) in the Comfort line up and offers high efficiency at a comparatively lower price (approximately between 4-5k installed). The Comfort 95 (59SU5, an ultra-low NOx 95% model) and Comfort 92 (59SC2) usually sell at around 4,000 to 5,400 dollars including installation.
In the meantime, the Comfort 80 (58SB0) is a simple 80 percent AFUE furnace, which is usually sold at the price of about $3,600 to 4,900 installed, and it is suitable in mild climates or in cases where the budget is tight. These Comfort series units do not have all the advanced features of the higher series but they are reliable in heating. On the whole, the model range of Carrier offers a variety of price options: a homeowner can spend a relatively small amount of ~$3k on a simple, efficient furnace or spend more than $7k on a state-of-the-art system with all the bells and whistles.
