Rheem Furnace Prices & Installation Cost (By BTU, By Stage, By Series, By Model) 2025

The average cost of Rheem furnaces is about 850 dollars to 4,000 dollars and above (equipment alone), and the total cost of installation is approximately 2,500 dollars to 7,800 dollars in the country. The precise cost is determined by such factors as the heating capacity (BTU output) of the furnace, whether it is single-stage, two-stage, or modulating, and the product line (Classic, Classic Plus, or Prestige series).

The table below shows the prices of Rheem furnaces in detail according to BTU size, furnace stage type, series, and popular models, as well as national average equipment and installed costs of each type.

Rheem Furnace Cost by BTU (Heating Capacity)

The size of the furnace (BTU) has a great influence on cost. The bigger furnaces that have greater BTU outputs tend to be more costly as compared to the smaller ones. As an example, a 100,000 BTU furnace will normally be more expensive than a 60,000 BTU furnace of the same efficiency and series.

The average home requires approximately 30 BTUs of heating per square foot; a 60,000 BTU furnace in a 2,000 sq. ft. house. The following are the national average price ranges of the common sizes of Rheem furnace, the equipment cost and the total installed cost:

BTU Capacity	Equipment-Only Price	Total Installed Cost
60,000 BTU	$700 – $1,900	$1,900 – $4,900
70,000 BTU	$800 – $2,000	$2,000 – $5,000
80,000 BTU	$900 – $2,200	$2,100 – $5,200
90,000 BTU	$1,000 – $2,400	$2,200 – $5,400
100,000 BTU	$1,100 – $2,500	$2,300 – $5,500

The mid-sized 80,000 BTU Rheem furnace will cost approximately $900 to 2,200 in the unit and approximately 2,100 to 5,200 with installation as the table indicates. Comparatively, a bigger 100,000 BTU model may cost an extra $200 to 300 on the furnace alone, and an additional 200 to 300 on the total cost of installation, on average. These estimates are based on average efficiency (80%-96% AFUE) and average installation conditions.

The actual prices may differ depending on the efficiency of the furnace model (the more efficient the AFUE of the same BTU the higher the price) and the local labor costs. Nevertheless, in most cases, higher-BTU furnaces are more expensive to purchase because they need bigger heat exchangers and more potent blowers to provide the additional heat capacity.

Rheem Furnace Cost by Stage (Single-Stage vs. Two-Stage vs. Modulating)

Burner stages of a furnace The burner stages of a furnace are the number of levels of heat output that the furnace can achieve. Rheem provides single stage (one heat setting) furnaces, two stage (high and low) furnaces and modulating (variable) furnaces which adjust continuously.

The more the staging, the more the cost is likely to be:

• Single-Stage Furnaces: They possess a single level of heat output. They are the cheapest and easiest, and they have fewer parts. A one-stage Rheem furnace unit may be as cheap as ~$700 on an 80 percent AFUE unit. Single-stage models (usually of the Classic series) cost an average of 2,500-4,500 dollars when installed. The trade-off is that they can run at full blast when they are not required, which results in minor temperature fluctuations.
• Two-Stage Furnaces: These have two settings of heat (typically ~6070 percent capacity on low and 100 percent on high). Two-stage Rheem furnaces are more evenly heated and more efficient during mild days. The cost of a two-stage furnace is usually around 1000 dollars and can go up to ~3600 dollars in case of higher capacity or high-efficiency furnaces. The average installed prices in Rheem lineup are approximately 3,100-5,500 dollars. Two-stage units are a few hundred dollars more than similar single-stage models, but they may be more comfortable because they operate on the low stage most of the time.
• Modulating (Variable) Furnaces: These are fully variable output and adjust the flame size in small increments to suit the heating need of the home. The modulating furnaces (Prestige series) produced by Rheem are the most efficient and comfortable. Such refinement is not cheap: the gear usually costs between ~$1,300 and up to $6,000+ on the most capacious models. The installed cost may be approximately between 3,700 and 7,800 dollars. Modulating furnaces are the most costly and most consistent in temperature and in many cases the highest AFUE ratings (up to 98%).

Stage Type	Unit Cost Range	Installed Cost Range
Single-Stage	$700 – $1,900	$2,500 – $4,500
Two-Stage	$1,000 – $3,600	$3,100 – $5,500
Modulating (Variable)	$1,300 – $6,600	$3,700 – $7,800

Single-stage Rheem furnaces are the cheapest to purchase and install and modulating Rheem furnaces are the most expensive. As an example, a simple single-stage 80% AFUE Rheem furnace may be about 3,000 dollars installed, and a high-end modulating 98% AFUE furnace may be 6,000 dollars or more installed.

The middle of the road 92-96% AFUE models (R92T, R95T, R96V) are in the middle, about 4000-5500 installed. These numbers show the usual trade-off between initial cost and efficiency/features: the higher the series and the more complex the furnace, the more it costs initially but the better it saves energy and provides comfort in the long run.

The homeowner must consider the cost of up-front versus the comfort and efficiency advantages. The two-stage models are a compromise between price and provide better comfort and efficiency than single-stage. It is also important to mention that the furnaces of higher stages usually belong to the higher series of Rheem (Classic Plus or Prestige), which also have other upgrades such as ECM blower motors and smart controls, which also adds to the price.

Rheem Furnace Cost by Series (Classic, Classic Plus, Prestige)

Rheem classifies its furnaces into three major series, which include Classic, Classic Plus, and Prestige. The series are related to various levels of performance, features and prices. As a rule, Classic series models are entry-level (less expensive, less efficient), Classic Plus are mid-range and Prestige are top-tier (high efficiency and features).

The following is a summary of each series and the average price range and main features:

Rheem Classic Series

• Efficiency: 80-92 percent AFUE. Classic series comprises the standard-efficiency furnaces of Rheem, such as 80 percent AFUE furnaces and some up to the low-90s AFUE. These are of low efficiency but not of ultra-high efficiencies of the best models.
• Price: Average of about 2,500 to 4,500 dollars installed. The cost of equipment-only of Classic series units is usually about 850 to 1,900 dollars in this series.) This renders the Classic series as the cheapest line in the Rheem line.
• Features: Less advanced features, more reliability and value. The majority of Classic models are single stage furnaces with standard single speed or multi-speed PSC blowers. They possess simple controls and do not have more advanced technologies of upper series. Advantages: The initial price is cheaper, good performance when it comes to mild or small-home heating. Cons: Less fuel efficient (more operating cost in cold climates) and less comfort control (temperature may vary more since it is single stage).

Rheem Classic Plus Series

• Efficiency: 80-96 percent AFUE. Classic Plus line covers a broad spectrum of efficiencies, including standard 80 percent models, as well as high-efficiency 95-96 percent AFUE models. The Classic Plus furnaces have a large number of ENERGY STAR 17 registered furnaces because of the increased efficiency.
• Price Range: Averagely installed at about 3,100 -5,500. The cost of equipment-only is approximately between ~$1,000 and $3,000, depending on BTU and efficiency). This medium-level price is based on the extra technology and efficiency compared to the Classic line, but it is also less expensive than the Prestige line.
• Features: More features than Classic. Classic Plus models may feature two-stage burners or high-efficiency single-stage burners and most are available with ECM (Electronically Commutated Motor) blower motors that are quieter and provide more control of airflow. They are usually better warrantied and possess some intelligent diagnostics (e.g., Rheems PlusOne diagnostics). Advantages: Reasonable cost-performance ratio – the increased efficiency will help to reduce energy bills, and two-stage/ECM functionality will enhance comfort. Cons: A little more expensive upfront than the Classic, and not quite as feature-rich as the Prestige series.

Rheem Prestige Series

• Efficiency: 90-98 percent AFUE (best-of-the-best). Prestige series encompasses the most efficient furnaces of Rheem with the highest efficiency of condensing furnaces in the 9598 percent AFUE range. They are perfect in cold climates where the highest efficiency is required and they comfortably surpass minimum ENERGY STAR efficiency requirements.
• Price Range: $3,700 -7,800 with installation (approximately). Unit prices (only) are normally about $1,500 to $4,000+ (the largest modulating units). The most costly Rheem furnaces are the prestige models, as they are designed and capable of more.
• Features: Complete set of features to be as comfortable and connected as possible. Prestige series furnaces are all high-end furnaces, typically with modulating (variable) gas valves and variable-speed ECM blower motors to provide accurate heating and airflow. They are frequently fitted with the EcoNet smart home system integration of Rheem (which enables remote control and monitoring through a smartphone app) . Other high-end features are superior diagnostics, extended or more comprehensive warranties and quietest operation because of superior sound-dampening design. Advantages: Optimal performance and comfort, long-term energy savings, intelligent technology. Cons: Much more expensive initial cost; the high-tech will not be used to the fullest in warmer climates where it is not needed to be that efficient.

To sum up, the pricing levels of Rheem are associated with the following series: a simple 80% AFUE Classic furnace on the low end (~2.5k installed), a mid-range 95% AFUE Classic Plus furnace in the middle (~4k-5k installed), and a high-end 98% AFUE Prestige furnace on the high end (usually 5k-7k installed). The customers will have an opportunity to select the series that suits their budget and performance requirements.

Remember that the total costs can be moved up or down these ranges by the complexity of the installation or add-ons (such as new ductwork, thermostats, etc.).

Rheem Furnace Cost by Model (Common Models & Prices)

The model numbers of Rheem (R92T, R96V, R801T, etc.) show the series and efficiency of the furnace and its features. As a rule, the model number (e.g. 92 or 96) is the AFUE efficiency rating, and letters indicate options: T usually means two-stage (or high-efficiency single-stage) model, and V usually means variable-speed blower (and in some cases modulating burner).

Some of the most popular residential gas furnace models of Rheem with their estimated equipment-only and installed prices are listed below. These are mid-sized unit (~70,000 BTU) and standard installation estimates:

• R801T (Classic Series): An 80 percent AFUE gas furnace that has a single-stage burner and multi-speed blower. It is a starter, builder grade model that is concerned with affordability. Price: about 2,300 dollars per unit, and about 3,500-3,600 dollars installed.
• R92T (Classic Plus Series): A 92 percent AFUE high-efficiency furnace that has a single-stage burner (and ECM blower motor). It is more efficient and yet is fairly easy to operate. Price: roughly 2,900 dollars on the unit, and roughly 4,400 dollars installed.
• R95T (Classic Plus Series): 95 percent AFUE, single-stage furnace, an efficiency step up. It is a trusted high-efficiency model that is not complex in terms of stages. Price: about 3,100 dollars per unit, and about 4,700-4,800 dollars installed.
• R96V (Classic Plus Series): A 96 percent AFUE two-stage furnace that has a variable-speed blower. The ECM blower and the two-stage burner enhance comfort and efficiency. This model is usually regarded as a high-efficiency furnace of great value. Price: about 3,465 dollars per unit, and about 5,200 to 5,300 dollars installed.
• R97V (Prestige Series): 97 percent AFUE furnace that has a variable-speed blower and modulating burner. This model is almost at the top of the Rheem range, and it is a high-efficiency and comfort model. Price: about 3800 dollars per unit, and about 5700-5800 dollars installed.

Rheem Model	AFUE Efficiency	Stage / Blower	Unit Price*	Installed Price*
R801T	80% AFUE	Single-stage, PSC blower	$2,300	$3,500 – $3,600
R92T	92% AFUE	Single-stage, ECM blower	$2,900	$4,400
R95T	95% AFUE	Single-stage, ECM blower	$3,100	$4,700 – $4,800
R96V	96% AFUE	Two-stage, Variable-speed	$3,465	$5,200 – $5,300
R97V	97% AFUE	Modulating, Variable-speed	$3,800	$5,700 – $5,800

*Prices are national averages for a mid-sized (≈70k BTU) unit. “Unit Price” is the equipment cost only, and “Installed Price” includes unit + typical installation labor and materials. Actual costs can vary based on capacity (BTU rating), local labor rates, and installation complexity.

Based on the table, you will notice that the prices increase as you go up the efficiency and advanced models. As an example, the 80 percent AFUE R801T (entry level single stage furnace) may cost about 3,500 installed, and the 97 percent AFUE R97V (high end modulating furnace) may be more like 5,800 installed.

The mid-efficiency 92-96 percent AFUE (R92T, R95T, R96V) are in the middle, about $4,000-5,500 installed. These numbers show the common trade-off between initial cost and efficiency/features: the higher the series and the more complex the furnace, the more it costs initially but the more energy it saves and the more comfortable it makes the home in the long run.

The homeowner is advised to select a model that suits his or her budget, efficiency and comfort requirements. Rheem furnaces are all backed by a 10-year parts warranty (with registration) and at least a 20-year or limited lifetime heat exchanger warranty, so you can rest easy no matter the price.
