This paper gives an in-depth comparison of Carrier vs. Rheem air conditioning systems in the American consumer view.

Which Brand Offers Better Energy Efficiency?

Energy efficiency is a very important consideration in comparing air conditioners. An efficient unit can reduce your electricity bills in the long run to a considerable extent. Seasonal Energy Efficiency Ratio (SEER) ratings show the efficiency of an AC to cool down with respect to the amount of energy used, the higher the SEER, the more efficient the AC.

Carrier has a reputation of stretching the envelope of AC efficiency. Its high-end models such as the Carrier Infinity series have SEER ratings as high as approximately 26.

As an example, the Carrier Infinity 26 model (24VNA6) has a rating of up to 26 SEER and is ENERGY STAR Most Efficient, which is due to a variable-speed compressor and Greenspeed intelligence technology. This kind of efficiency can be converted to significant savings on your utility bills throughout the life of the system.

Rheem also manufactures efficient units but the highest SEER is slightly lower. The high-end EcoNet-enabled Prestige line produced by Rheem can be rated as high as 20 to 21 SEER, still efficient and usually ENERGY STAR qualified, but not quite up to Carrier standards.

It implies that the most efficient unit of Carrier can be more efficient than the most efficient unit of Rheem in cutting down electricity consumption.

With that said, the difference in efficiency is only important when you use your AC a lot or when you live in a hot climate. The two brands have mid-range models of about 14-18 SEER that suffice in most homes.

Carrier just has an advantage on the ultimate efficiency of the people who want to have the lowest energy consumption. Remember that higher SEER units tend to be more expensive at the outset. When initial budget is limited, a Rheem unit with a decent (but not all-time) SEER may be a better compromise. Nevertheless, when it comes to the latest efficiency, Carrier is more likely to win in the energy efficiency.

Which AC Units Operate More Quietly?

Nobody would like to have a noisy air conditioner that will interfere with his or her peace of mind at home. The amount of noise may differ considerably among models and brands, and is usually expressed in decibels (dB) in the case of the outdoor condenser. The lower dB is quiet.

Carrier has made investments into noise-reduction technologies, and frequently highlights quiet performance, particularly in its high-end lines. A lot of Carrier central AC systems have sound-dampening insulation and unique fan designs.

The outcome: there are Carrier models that are very quiet, with a sound level of only about 51 53 dB, or about the sound level of a quiet conversation. Even their mid-range two-stage models tend to run in the mid-60s dB range which is still fairly quiet. The variable-speed compressors that Carrier uses enable the unit to operate at low speed most of the time, and this keeps the sound level low.

Rheem is also fairly quiet in operation, at least in newer models, though not as quiet as the best Carrier models. High-end Rheem models such as the Prestige model usually run at low-70s dB full speed.

Practically, the high-efficiency two-stage or variable models of Rheem operating at partial loads will be relatively silent and probably acceptable in a residential area. Carrier can however be at an advantage in noise-sensitive applications, since its high-end models can be much quieter at low or moderate speeds.

Are Carrier or Rheem Air Conditioners More Durable?

Such a large investment is a big factor in terms of durability and longevity. Both Carrier and Rheem manufacture fairly dependable equipment, although there are a few differences that have been reported in the industry reviews and by the owners.

Carrier is well known in terms of reliability and long-term performance. A Carrier central air conditioner should last about 10 to 15 years with proper installation and maintenance.

Carrier units are frequently commended in terms of their build quality. Carrier is the inventor of the modern air conditioning and still utilizes the high-quality components and materials. Their best models have heavy-duty scroll compressors and coils that are shielded (such as WeatherArmor casings) against wear and tear.

Rheem is a highly reputable manufacturer, but it is usually regarded as one step lower than Carrier in terms of sheer longevity. Rheem ACs usually last homeowners 5 to 10 years before some of their major parts may require replacement.

Certain HVAC professionals call Rheem a mid-range system in terms of durability: it is solid, but it can be more susceptible to small problems in the long run. Nevertheless, the newer Endeavor series of Rheem has been improved in terms of design and is made of all-aluminum coils to avoid rusting. A lot of Rheem ACs continue to run a decade with ease when maintained.

In brief, Carrier is more likely to be more durable and reliable in the long run, and Rheem is also good in terms of durability at its price. Both brands can have their maximum lifetime through regular maintenance and annual servicing.

How Do Carrier and Rheem Prices Compare?

To a large number of consumers, price is a determinant. The cost of buying and installing a central AC may be very different depending on the efficiency of the model, size (tonnage) and other features.

In general, Carrier is a high-end brand and it is more expensive than Rheem which is aimed at a more affordable market. The low end of a full Carrier system will be about 3,000 dollars, and a large, highest-efficiency system will cost more than 15,000 dollars.

Carrier will usually add more sophisticated technology and increased performance in exchange of the increased price.

Rheem, however, has a reputation of being cost-effective. The initial cost of Rheem AC systems is usually cheaper than the same Carrier systems. Rheem central air units can be estimated to be installed at an average price of between 3300-6700 dollars depending on the average size and efficiency.

This makes Rheem appealing to price-conscious buyers, and the high prices of Carrier could be explained by its long life, low noise levels, and high-tech performance.

Is Installation More Complex for Carrier or Rheem Systems?

The performance and the life of an air conditioning system depend on proper installation. The process may be complicated or simplified by the design features of some brands.

Proprietary technologies and special components may make carrier systems more complex, particularly on the high end. To give an example, the Infinity series has a communicating thermostat control and variable-speed compressors which need a trained technician who is conversant with the Carrier set up.

Carrier parts may be special, which may add repair cost or lead time. Nevertheless, Carrier has a wide dealer network and it is not hard to find a qualified installer.

Rheem systems, in comparison, can be called installer-friendly. Rheem also makes their units in standardized parts, which makes repairs faster and less costly as a lot of the parts are off-the-shelf.

An average HVAC technician is able to install a Rheem without any brand specific training. This may lead to reduced labour cost or easier maintenance in the long term. In any case, both brands need a licensed and experienced HVAC installer.

The high-end Infinity series outdoor unit (pictured) by Carrier is technologically advanced and has to be installed by a professional. Carrier units are sleek and have complicated and high-efficiency components.

Who Offers Better Customer Support and Warranty?

Once it is bought, warranty and support may be the most important thing in case of something wrong. Both Carrier and Rheem offer warranties on their equipment and have customer support channels, however, the coverage is different.

The air conditioners sold by Carrier are usually covered by a 10-year limited parts warranty (with registration) that covers major parts such as the compressor and coils. Labor is normally not included.

Carrier also provides an option to buy extended warranties with dealers to get extra protection. The support to the customers is usually good with a large network of authorized service providers.

Most of the models also come with a 10-year limited parts warranty (with registration) by Rheem. Rheem in other instances offers conditional warranties on unit replacements in case of compressor failure within a specified period.

But exclusions may be substantial, and one should read the small print. Rheem has a reputation of customer friendly approach and has a wide network of service contractors. The owners of Carrier tend to be very satisfied because of the reduced amount of problems, whereas the owners of Rheem enjoy the assistance of the brand and the reduced initial price.

What Technology and Smart Features Do They Offer?

New air conditioners are equipped with numerous technology and smart home options to enhance comfort and ease. Both Carrier and Rheem incorporate high-tech systems, which are proprietary.

Carrier is an innovation-oriented company that provides flagship Infinity systems. Its Greenspeed 1 Intelligent has a variable-speed compressor that allows high precision temperature and humidity control, as well as energy savings.

Infinity System Control is a premium touchscreen thermostat, which is Wi-Fi connected and can be integrated with Amazon Alexa or Google Home. The Carrier suite of smart features enables remote monitoring, scheduling and advanced diagnostics with the Carrier Home app. Even the middle-level Performance series units usually have two-stage compressors and are compatible with smart thermostats.

Rheem possesses the EcoNet platform, a smart thermostat and mobile application that is capable of controlling Rheem air conditioners, furnaces and even water heaters. EcoNet provides maintenance notifications, remote temperature control, and compatibility with a few smart home systems.

Rheem has also enhanced sustainability of its products and has been awarded with energy innovation. Some models have inverter-driven (variable speed) compressors like the Carrier method. In general, both brands are technologically advanced, and Carrier is usually ahead in terms of innovative HVAC-specific functions, whereas Rheem is more interested in an all-in-one, environmentally friendly platform.
