Rheem air conditioners are widely known for delivering dependable performance, solid energy efficiency, and good overall value. The company has built a strong reputation in the HVAC industry by offering systems that balance reliability with reasonable pricing.
Rheem’s current central air conditioner lineup is organized around its Endeavor platform, which ranges from basic single-stage units to advanced variable-speed systems designed for improved comfort and efficiency.
Many newer Rheem models are also transitioning to R-454B refrigerant, a lower-global-warming-potential refrigerant that is gradually replacing older R-410A systems across the HVAC industry.
In this guide, I’ll break down Rheem’s current air conditioner models and help you decide whether a Rheem system is the right choice for your home.
Rheem air conditioners – Quick guide!
Rheem Endeavor Prestige RA19AY
The Rheem RA19AY is the most advanced air conditioner in Rheem’s current lineup, using a variable-speed inverter compressor for precise temperature control and excellent efficiency. With ratings of up to about 20 SEER2 and compatibility with Rheem’s EcoNet smart thermostat, it delivers outstanding comfort, quiet operation, and energy savings.
Rheem Endeavor Classic Plus RA16AY
The RA16AY is a strong middle-tier option that uses a two-stage compressor to improve comfort and humidity control compared with single-stage systems. With efficiency ratings of up to about 17 SEER2, it offers a great balance of price, efficiency, and performance for many homeowners.
Rheem Endeavor Select WA13NY
The WA13NY is Rheem’s most basic central air conditioner, designed primarily for budget installations and simple cooling needs. While it meets current efficiency requirements, its single-stage compressor and lower efficiency rating (around 13.4 SEER2) mean higher energy costs and less consistent comfort compared with Rheem’s higher-tier systems.

How to get the best Rheem AC installation price in your area
Installing a central air conditioner is a major investment, and prices can vary significantly depending on your contractor and home setup.
To get the best deal, I recommend getting at least three quotes from licensed HVAC installers, asking for a Manual J load calculation, and comparing warranties and installation details carefully.
You can learn more about typical installation costs in my guide to central AC installation pricing.
Why SEER became SEER2
You may notice that newer air conditioners list SEER2 ratings instead of the older SEER ratings.
This change was introduced by the US Department of Energy in 2023 to better reflect how air conditioners perform in real-world conditions.
SEER2 testing uses higher external static pressure and updated testing procedures, which more closely simulate how HVAC systems operate inside actual homes with ductwork and airflow resistance.
As a result, SEER2 ratings provide a more realistic picture of energy efficiency and operating costs than the older SEER standard.

ACLAB Note:
In the Southeast and Southwest United States, most residential central air systems must have a SEER2 rating of at least 14.3, although larger systems above 45,000 BTU may qualify with 13.8 SEER2.
In the Northern U.S., the minimum efficiency requirement for residential air conditioners is 13.4 SEER2 (roughly equivalent to 14 SEER).

Some newer Rheem systems include a refrigerant detection system designed for A2L refrigerants like R-454B. This safety feature helps detect refrigerant leaks and supports the industry transition to lower-GWP refrigerants.
Inverter-Driven Variable Speed Compressors
Higher-end Rheem air conditioners use inverter-driven compressors that can adjust their output gradually rather than turning on or off. This allows the system to run longer at lower speeds, improving efficiency, temperature stability, and humidity control.

Rheem AC units warranty analysis
Rheem’s warranties are fairly standard within the HVAC industry. Most residential air conditioners include a 10-year limited parts warranty when the unit is registered after installation.
Some premium models may also include a 10-year conditional unit replacement warranty, meaning Rheem will replace the entire condenser if a major component fails during the coverage period.
Like most manufacturers, labor is not included, although homeowners can purchase extended protection plans such as Rheem’s Protection Plus program through their contractor.
The quality of the installation plays a major role in whether your warranty remains valid. If an HVAC system is improperly installed or not maintained according to the manufacturer’s guidelines, Rheem may deny warranty claims, which is why choosing a qualified contractor is just as important as choosing the brand itself.

Homeowner and buyer reviews
From Consumer Affairs - 5 Star review
“Rheem is a good product, well made, and has a great track record. Parts are easy to get and it is easy to repair when needed even though that's rarely. The life span of a Rheem is 20-25 years. If I had to purchase another heating and air unit, it would be a Rheem."
How do Rheem air conditioners compare to its competitors?
Rheem vs Lennox
Lennox’s high-efficiency central air conditioners have a higher SEER rating: some go up to 28, which is significantly better than the ratings on Rheem air conditioners.
If you want the lowest operating cost, go with Lennox.
Rheem may lack the new technological advances, but it makes up for that in affordability. Some Lennox models cost up to $10,000 to install, while Rheem products average $4,000.
Both companies offer a wide selection of models to suit any budget, and both offer a reliable product backed by decades of manufacturing expertise.
Rheem HVAC systems are the cheaper option.

Rheem vs Carrier
Carrier offers several patented technologies that increase energy efficiency in their air conditioners, and their products are known for their excellent manufacturing process.
Carrier builds some of the quietest indoor air quality equipment on the market, but it also manufactures some of the most expensive.
Carrier requires all its products to be installed by North American Technician Excellence (NATE)-certified technicians who have been trained at their Indianapolis factory.
This ensures that the unit is installed properly and that the HVAC professional is qualified to maintain and repair it in the future.
Any qualified air conditioning technician can install a Rheem system, which may mean your installation has a higher chance of being less than ideal.
One drawback to purchasing a Carrier is its warranty; it doesn't cover labor for normal wear and tear.
Rheem ACs are cheaper and can last just as long as Carrier’s, as long as the installation is good and your AC gets regular, scheduled maintenance.

Rheem vs Trane
Trane has a solid reputation for producing high-quality, reliable HVAC systems.
This comes at a price. Its air conditioners, heat pumps, and furnaces are some of the most expensive on the market.
Trane’s commitment to quality is evident in how it puts every unit through testing that approximates five years of extreme wear and tear.
Their XL series is a budget-friendly option, but I recommend not purchasing these base products because you can purchase a similar Rheem unit for less money.
Trane's units don't have the highest SEER ratings or the lowest sound levels. Nor are they the quietest or the most energy-efficient on the market. However, they are some of the most durable.
Rheem’s strength is good-to-excellent SEER at an affordable price.
