Our Preferred HVAC Brands
Today’s Homeowner recommends a few HVAC brands to our readers. Below you’ll see our latest suggestions and their unique superlatives. You can also explore our list of the best HVAC companies for help finding a trustworthy service provider.
What’s Our Take on Rheem Air Conditioners?
Rheem is widely regarded as a trusted and reliable brand for water heaters, gas furnaces, and central air conditioners—particularly for homeowners looking to save some money on AC replacement or installation costs.
The pricing for Rheem air conditioners falls between $3,000 and $4,800, which pales in comparison to the $10,000+ you’d see from higher-end companies like Lennox and Trane.
Rheem falls short in comparison to a lot of the competition when it comes to efficiency. The seasonal energy efficiency ratio (SEER) rating you’ll find from this company ranges from 13 to 20.5 and averages around 15 for most units.
Compared to the high end of 24 you get from Bryant and Carrier and 28 from Lennox, the efficiency from Rheem is lacking—meaning you’ll spend more on electricity to power your Rheem AC than you would with some more efficient options.
If you do go with Rheem, we recommend opting for a model that hits that 20.5 mark to maximize efficiency. The Rheem Variable-Speed RA20 is one of the company’s best options for balancing efficiency and long-term savings with upfront costs.
Rheem Air Conditioner Pros & Cons
The tabs below cover Rheem’s high-level pros and cons. We recommend considering these points as you compare Rheem’s air conditions to other brands.
What Is Rheem’s Air Conditioner Pricing?
As mentioned above, Rheem is a budget-friendly option for home cooling equipment. The average air conditioner from the company costs around $4,000—most fall between $3,000 and $4,800 per unit. The table below includes a quick look at how the different models offered by Rheem compare in terms of pricing.
| Low-End Models | Mid-Range Models | Premium Models |
| $3,000-$3,500 | $3,500-$4,200 | $4,000-$4,800 |
Rheem ACs are less expensive than similar equipment you’ll find from other companies, and they provide outstanding value for the money. However, most models aren’t equipped with some of the features you’ll find from other manufacturers.
For example, only the Prestige Series RA20 is equipped with a variable-speed compressor, which allows for increased efficiency and quieter operation. The video below explains why variable-speed compressor help make your equipment more efficient:
Most models also don’t have wireless connectivity, which allows you to control your home’s climate remotely. These features are more prevalent from companies like Lennox, which have higher equipment costs.
Rheem uses a national network of third-party installers to provide its equipment to homeowners across the country. The installation cost for Rheem air conditioners will vary based on the HVAC professional you choose.

How Do Rheem Air Conditioner Models Compare?
Rheem offers around 20 different air conditioner models for residential installation and use, which are split into three series:
- Classic (and the Classic Plus series)
- Select
- Prestige
In our opinion, the Prestige Series provides the most value for the money—primarily because it has the highest efficiency ratings and includes variable-speed compressors. This means the unit produces less noise inside and outside your home, and it also makes your system more efficient overall. You’ll pay more for a model from the Rheem Prestige Series, but the higher efficiency will mean greater energy savings over time.
We’ll include a breakdown of all of the air conditioner models offered by Rheem in the following sections. To help you decide which model might be best for your home, we’ll include some information about the average price range and efficiency ratings of each offering.
Rheem Classic Series Single-Stage RA13
The RA13 belongs to the most affordable series offered by Rheem: the Classic Series. As the name implies, this is a single-stage AC, so it doesn’t offer variable blower speeds. Thus, its efficiency is quite low—and the units are noisier than those with a variable-speed or two-stage compressor for more control over airflow.
- Available sizes: 1.5 to 5 tons
- Average cost: $3,000 to $3,500
- Compressor speed: Single-stage
- Compressor type: Scroll compressor
- Efficiency rating: 13.0-15.5 SEER/11.5-13 EER
Rheem Classic Series Single-Stage RA14
The Rheem RA14 has a decent efficiency rating of 15.0 SEER, and it uses a Copeland scroll compressor and composite base pan to reduce noise during operation. This model also has a single-stage compressor. The value for the money is quite good—although the efficiency rating might end up costing you more in the long run as opposed to paying more for a higher-efficiency unit in the first place.
- Available sizes: 1.5 to 5 tons
- Average cost: $3,000 to $3,500
- Compressor speed: Single-stage
- Compressor type: Scroll compressor
- Efficiency rating: 15.0 SEER/12.5 EER
Rheem Classic Series Single-Stage RA14**W
This single-stage AC from Rheem is one of the smaller models—available from 1.5 tons up to 3.5 tons—making it a good option for smaller homes only. It has an efficiency rating of 15 SEER, which is below average, but the price is really what makes this unit appealing. This unit uses a composite base pan to reduce noise when it’s running.
- Available sizes: 1.5 to 3.5 tons tons
- Average cost: $3,000 to $3,500
- Compressor speed: Single-stage
- Compressor type: Scroll compressor
- Efficiency rating: 15.0 SEER/12.5 EER
Rheem Classic Series Single-Stage RA16
The RA16 is another entry in the Classic Series from Rheem, boasting a slightly higher efficiency than the previous models—16.0 SEER. Like all of the other entries in the Classic line, the RA16 features a scroll compressor for better efficiency and a composite base pan to reduce noise. This unit loses some potential efficiency due to the simple, single-stage blower motor.
- Available sizes: 1.5 to 5 tons tons
- Average cost: $3,000 to $3,500
- Compressor speed: Single-stage
- Compressor type: Scroll compressor
- Efficiency rating: 16.0 SEER/13.0 EER

Overall, this provides quieter operation in many cases, as well as increased efficiency. This model is only available in two sizes—2 or 3 tons—and it features the same composite base pan and scroll compressor present in the previous models mentioned.
- Available sizes: 2 or 3 tons
- Average cost: $3,000 to $3,500
- Compressor speed: Two-stage
- Compressor type: Scroll compressor
- Efficiency rating: 17.0 SEER/13.0 EER

This model features a small refrigerant line (7mm), which demands less refrigerant and has less impact on the environment.
- Available sizes: 1.5 to 5 tons
- Average cost: $3,000 to $3,500
- Compressor speed: Single-stage
- Compressor type: Scroll compressor
- Efficiency rating: 15.2 SEER2/12.0 EER2

Rheem Select Series Single-Stage WA14**W
The WA14**W is another model that Rheem notes is suitable for residential and light commercial use. It’s a smaller model—topping out at 3 tons—and it has a lower efficiency rating than most others due to the single-stage motor and the larger refrigerant line size.
- Available sizes: 1.5 to 3 tons
- Average cost: $3,500 to $4,200
- Compressor speed: Single speed
- Compressor type: Scroll compressor
- Efficiency rating: 14.0 SEER/12.5 EER

What Are Rheem Air Conditioner Reviews From Homeowners?
We always strive to bring you the most accurate information possible. To that end, we’ve read through over 100 customer reviews for Rheem from sites like Better Business Bureau (BBB), TrustPilot, and Google Reviews. We’ve specifically looked for information regarding product durability, installation services, and warranty coverage in Rheem HVAC reviews, and we’ve separated out reviews for other Rheem products, like water heating equipment and furnaces.
Unfortunately, based on a lot of reviews, it seems that you get what you pay for. Rheem might be a cheaper option when it comes to air conditioners, but many of the negative reviews note a short equipment lifespan. It’s clear from the positive reviews that durability isn’t always an issue, and it is worth noting that the much lower equipment costs could still be worth it—even if it means a shorter system lifespan. You can extend the life of your cooling system with proper maintenance, though.
It’s worth noting that there was a class action lawsuit filed against Rheem due to defective heat pumps and air conditioners. There has been no resolution to the lawsuit as of this writing.
Some of the customer complaints stem from issues with installers, who are local contractors. While this isn’t the fault of Rheem specifically, it does mean your overall experience can vary based on the installer you choose.
Finally, some of the negative reviews for Rheem are about the warranty coverage. In all cases that we looked into, the warranty coverage offered was as it was stated, but some customers felt that the limited warranty was unfair—like in the case of a parts warranty not being applicable after specific parts were no longer manufactured. Just be sure to read your warranty documentation from Rheem carefully before buying an AC unit from the company.
What Rheem Features Should You Consider?
Rheem is a budget AC option, so there aren’t many features to speak of compared to other manufacturers. We’ll list some of the things we recommend thinking about when choosing a Rheem air conditioner below.
- Compressor type: Most Rheem ACs use a scroll compressor, which is less efficient and noisier than the twin rotary compressors in the more expensive models.
- EcoNet capability: EcoNet is Rheem’s feature for remote temperature control. This is a nice option that allows you greater control over your system, as well as the potential for higher efficiency. You will need a WiFi-enabled thermostat to get access to this home comfort feature.
- SEER/SEER2 rating: The SEER and SEER2 ratings tell you how efficient your AC will be. You’ll pay more for higher efficiency ratings from Rheem, but systems with higher SEER ratings will often save you money on electricity over time. It’s also worth noting that the systems from Rheem are Energy Star rated, so they are eligible for energy-efficient rebates.
- Stages: Two-stage models are more efficient than single-stage options, and they provide a more stable interior temperature.
- System size: Rheem ACs are available from 1.5 up to 5 tons, although some models have more restrictive sizes. Make sure you match your system size to your cooling demands and home size.
- Type of AC: Rheem offers a few different types of AC systems, all of which carry different efficiency ratings and capabilities, so be sure to choose the one that suits your home and heating/cooling needs best.
So, Is a Rheem Air Conditioner Worth It for Your Home?
Overall, Rheem is a decent option for home air conditioning systems. The ACs are significantly cheaper than they are from most other brands, making this a good budget option for upfront savings. However, lower equipment costs do translate to some issues with durability—according to customer reviews—and the brand as a whole has lower efficiency ratings than some of the more premium options out there.
The Rheem Prestige Series Variable-Speed RA20 is one of the company’s top models. It has the highest efficiency rating—and although it’s the most expensive option from the company, it’s the model we recommend most.
