Best Rheem Furnace Reviews of 2022 – Complete Round-up

| Last Updated: July 29, 2021

When winter comes around the corner, the time to check your forgotten furnace comes again. It might be that it is time that you thought about replacing your older model for a new and more efficient one.

Rheem has made its name in the furnace industry by making some of the most valuable products out there. So in this article, we will focus on Rheem furnace reviews.

Before that, you need to know what you are getting into. So let’s first see what the other companies in this industry have to offer and how Rheem compares to them. 

How Does Rheem Compare to the Competition?

As we mentioned, Rheem is one of the top suppliers of furnaces, but there are other manufacturers out there as well, and some might argue that they supply better furnaces. So let’s compare and see which one is more suited for you.

Rheem vs. Lennox Furnace

Lennox was founded in 1895 by Dave Lennox as a furnace company. Today, it has expanded to include all HVAC products in its product offerings.


One of the plus points of Rheem is that it offers a transferable warranty. If you are selling your home or moving somewhere else, they will accommodate you. In the case of Lennox, that does not happen.

Lennox only offers five to ten years of limited warranty on parts and compressors, whereas Rheem always gives a ten-year part warranty with 20 or limited lifetime warranty for heat exchangers.


Rheem furnaces lie in the $800-1600 range, while Lennox has a range of $1,100-2,400. Considering the reliability, durability, and efficiency of Rheem furnaces, their price range makes sense and is more cost-efficient.


When it comes to material, most manufacturers use the same aluminized steel, aluminum, or stainless steel, and both Lennox and Rheem are no different.

Rheem vs Carrier Furnace

Carrier has been making refrigeration, heating, and air conditioning products since 1902. They provide their services throughout the world and have industry-recognized energy efficiency certifications. 


The non-condensing gas furnaces of Carrier have a ten-year warranty on parts and 20 years on the heat exchanger. For condensing gas furnaces, only the Infinity line has a limited lifetime warranty option for the heat exchanger.

It is not as low as Lennox, but Rheem offers lifetime warranties on most of its new furnaces.


Carrier has a price range of somewhere from $1,100 to $2,500, which is significantly higher than Rheem.


Carrier’s highest efficiency furnace is 98.5% AFUE, while Rheem also has 98%, but a lot of Carrier models also lie in the 80% range, and very few of them have the modulating function.

Rheem vs Trane Furnace

Trane is one of the largest HVAC manufacturers in the world and has 104 manufacturing facilities located throughout the world.

Trane does not have the option of a lifetime warranty. Its warranty will range from one to 20 years only, depending on the product. And we have already established Rheem’s range.


Trane furnaces are some of the more expensive models. Their price ranges between $2,400 and $4,500. This is comparatively high compared to not only Rheem but also Carrier and Lennox.


Trane’s highest AFUE rating is 97.3% and goes down to 80%. This is lower than the 98% that Rheem has, though not by a huge amount.

Review of the Best Rheem Furnaces

If you are still reading, that means you have chosen Rheem as your supplier and might already have your eye on one of the mentioned furnaces.

So, without wasting any more time, let’s jump into our picks for the best Rheem furnaces. 

Best Overall

Rheem R97V


Energy Efficiency (AFUE): 97%

Parts Warranty: 10 Years Limited Warranty

Unit Warranty: Limited Lifetime Heat Exchanger Warranty / Limited Lifetime Conditional Unit Replacement

We may earn commission from purchases made from our links, at no additional cost to you

Why it Stands Out to Us

The R97V is one of Rheem’s most efficient models while not going too high on cost. It uses modulating operation (40% to 100%), i.e., modulation fuel injection rate. This increases efficiency significantly and also reduces noise.

According to Rheem, this model has a new patented heat exchanger, which effectively reduces noise by 20%. The heat exchanger modulating function combined with the variable-speed fan makes this one of the top efficiency furnaces of Rheem.

You can change the heat setting between 40%, 65%, and 100%, depending on your climate. You might not need to go over 40%, while some people might need to crank up the heat to 100%.

Bottom Line

This model is our overall best pick because it comes from Rheem’s Prestige series of furnaces that are equipped with new technologies, are more reliable, have limited lifetime warranties, and are more efficient.    


EcoNet enabled

97% high energy efficiency

EcoNet, Energy Star, and AHRI certified

Modulating operation reduces cold spots

Variable speed motor and new heat exchanger reduces noise


Warranty does not cover labor costs

Best Rheem Gas Furnace

Rheem Classic Plus Series AFUE R801T


Energy Efficiency (AFUE): 80%

Parts Warranty: 5 Years Limited Warranty

Unit Warranty: 20-Year Heat Exchanger Limited Warranty

We may earn commission from purchases made from our links, at no additional cost to you

Why it Stands Out to Us

We find this to be one of the more simple models. Given that it is a classic model, it has 80% energy efficiency, which is still high compared to some other furnaces on the market.

It uses aluminized steel to reduce corrosion and thermal fatigue, significantly increasing its durability. The hemmed edges and ¼-turn doorknob makes handling and maintenance easier.

One of the things about this model is that it was one of the first furnaces to be certified for Ultra-low NOx emission, making it highly environment-friendly.

Bottom Line

Rheem delivers quality, whether it’s an old model or new. So if you are looking to save money but still buy something that will last and give consistently hot water, this model will do the job. 


Eligible for SCAQMD

Dip switches for easy setup

Insulated blower compartment

First ultra-low NOx emission furnace

Aluminized steel for reducing thermal fatigue


Only for up-flow configuration

Best Rheem High-Efficiency Furnace

Rheem R98V


Energy Efficiency (AFUE): 98.7%

Parts Warranty: 10 Years Limited Warranty

Unit Warranty: Limited Lifetime Heat Exchanger Warranty / Limited Lifetime Conditional Unit Replacement

We may earn commission from purchases made from our links, at no additional cost to you

Why it Stands Out to Us

This is one of the most energy-efficient furnaces by Rheem. Sometimes, higher energy efficiency leads to more problems and maintenance issues. But this R98V model does not pose this problem. It is backed with a lifetime warranty for the heat exchanger and conditional unit replacement.

The EcoNet thermostat has built-in Wi-Fi and allows for voice commands as well. It’s easily installed and is touch-enabled, giving you different operating modes, depending on the outside temperature.

The water management system will ensure that it turns off when there is a blocked drain to prevent leakage. It also has a reliable Direct Spark Ignition and ultra-low noise operation.

Bottom Line

If budget is not your concern and you are looking for the best and most efficient furnace that is not only environmentally friendly but also saves a lot of money down the road on fuel, then this is your best bet.


EcoNet enabled furnace

Limited lifetime warranty

98% high energy efficiency

Variable speed blower motor

Multistage operation for higher efficiency


Only works on too high or too low and has no option for intermediate heating

Best Rheem 2-Stage Furnace

Rheem R96V (RFQA)


Energy Efficiency (AFUE): 96%

Parts Warranty: 10 Years Limited Warranty

Unit Warranty: Limited Lifetime Heat Exchanger Warranty

We may earn commission from purchases made from our links, at no additional cost to you

Why it Stands Out to Us

Model R96V from the Prestige series is EcoNet enabled and enjoys all the perks that come with it like the EcoNet touch screen controller with voice activation.

It also has variable speed, allowing two-stage operation, so, if needed, it can go one step up for an increased heating performance in colder areas.

There pre-marked hoses that ensure proper water drainage. The use of aluminized and stainless steel increases durability and reduces corrosion.

It also has a solid bottom, self-priming condensate trap, and dip switches. Other than this, all the Rheem specific features for safety and efficiency are included in it. 

Bottom Line

Two-stage furnaces are more efficient and more suitable for colder areas. Instead of just going on and off, they can be increased on heat capacity. This model is compatible with both single and two-stage thermostats, but the former will give a better performance here.


Two-stage operation

96% energy efficiency

Variable-speed ECM motor

Energy star and AHRI certified

Limited lifetime warranty for heat exchanger


Primary warranty for only ten years

What Kind of Warranty Does Rheem Offer?

Most of the better quality manufacturers will offer at least 20 years of warranty on a furnace, and Rheem is no different, and some of them also have limited lifetime warranties. The premium models have higher warranties, and it differs among the parts and heat exchangers.

The parts warranty is generally five to ten years with five for classic models and ten for Prestige models. Heat exchangers lie on the 20 years to limited lifetime warranty ranges.

A unique feature that Rheem offers is an additional Protection Plus Warranty. After your limited warranty expires, you can still be under the warranty umbrella for four more years if you choose this option. This type of warranty covers all parts and labor, maintenance, and transfer of warranty.

For warranty details about a particular furnace, you can visit the Rheem website and enter the furnace serial number.
