What Is A Rheem Air Conditioner?

rheem air conditioner

The Rheem Air Conditioner is a popular product released by Rheem Air Company. Rheem is a brand widely used by businesses and homeowners. This air conditioner is particularly popular among contractors and dealers in the HVAC technologies.

Rheem designed this product to maximize the efficiency of its features while keeping the price low enough to be accessible to all consumers. The air conditioner comes in many different types with different speeds and model characteristics.

Pro​duct Specs  

The Rheem Air Conditioner has a number of unique features.

Modulating Burners

First off, these air conditioners have a modulating temperature feature. This means they can offer the best climate control and are capable of unbalancing temperatures. With modulating burners, they can control dehumidification during their cooling cycles with a variable speed motor.

These modulating burners are present in most of the air conditioners Rheem puts out. Rheem values them highly for their ability to convey accurate temperature controls. These burners also increase the air conditioners’ effectiveness and efficiency.


Rheem Air Conditioners have been designed to maximize efficiency. Rheem aims to help consumers reduce their energy expenditure as much as possible.

Air conditioners have what is known as a SEER rating. This rating describes an air conditioner’s efficiency. The Rheem Air Conditioner has SEER ratings of up to 19.5. The higher the rating, the more energy efficient an air conditioner is. This means that Rheem air conditioners are quite efficient. An example of a 19.5 rated air conditioner is the Rheem Prestige RASL-JEC Central AC.

Comfort Control System

The comfort control system is present in the Rheem Prestige line of air conditioners. This special system provides on-board diagnostics and history error codes.

These air conditioners also have programmable thermostats. The advantage of this feature is that it can save consumers a great deal in their electric bills. It will also help users cool their home according to their chosen schedule.

Noise Level and Refrigerant

Another significant feature is the air conditioner’s noise level and refrigerants. Rheem prioritized these aspects to accommodate consumers bothered by the noise created by most air conditioners.

The Rheem air conditioner uses Puron refrigerant.
