A failing air conditioner in the blistering summer heat isn’t something one can wait to replace. While there are plenty of options to choose from, knowing which brands are the best choices can be a confusing process. Selecting an air conditioner from one of the well-known top AC manufacturers is a great choice for those who can afford it, but not everyone can. That doesn’t mean there aren’t great affordable options out there. This guide will review some of the best air-conditioner brands to purchase, whether it’s a high-end system or a quality budget-priced model.

The Best Air Conditioner Brand Option: Trane

1. Trane

Known for: Trane is highly regarded for building efficient and durable (though expensive) air conditioning units.
Editors’ Choice: All the technologies that Trane uses to improve durability and efficiency are featured in its Trane XV-20i.

Trane’s slogan, “It’s hard to stop a Trane,” isn’t just a creative use of the pun. The company, which was founded in 1913 and headquartered in Ireland, has a well-established reputation for being one of the most reliable HVAC manufacturers, and that extends to the air conditioning part of its business. Among the durability features of Trane’s products are its WeatherGuard II, a polycarbonate top that protects its air-conditioning units, and its DuraTuff base pan, which is rustproof.

But Trane’s units aren’t just durable; they also feature technologies that make them some of the most efficient air conditioners, including variable speed compressors that minimize energy use and ComfortLink II technology that improves its ability to cool a home evenly. The one downside to Trane’s air conditioners is their premium price tag, which can put them out of reach for some customers.

3. Rheem

Known for: Rheem’s reputation for improving the environment shows in both its manufacturing operations and the energy-saving technology in its air-conditioning units.
Editors’ Choice: The RA 17 is one of numerous Rheem air conditioners that feature its EcoNet energy-saving technology.

Like many HVAC companies that started in the early 20th century, Rheem, founded in 1925, expanded its existing heating business to include cooling by developing its own line of air conditioners to meet the growing residential demand for cool air in the 1950s.

Rheem is one of the most environmentally responsible HVAC companies in the business—the company has a 2025 goal of producing zero landfill waste and reducing greenhouse emissions by 50 percent. In addition to reducing the carbon footprint of its manufacturing operations, Rheem is also known for producing ecologically friendly air conditioners. Its EcoNet technology makes it easy for Rheem AC users to adjust the temperature when not at home, lowering the electric bill while decreasing energy consumption.

4. Carrier

Known for: Carrier’s air conditioning units are some of the most efficient on the market.
Editors’ Choice: With a two-stage compressor that allows the air-conditioning unit to operate in a low-power mode to maintain the set temperature on the thermostat, the Infinity 21 central air conditioner exemplifies the efficiency Carrier offers.

Carrier is highly regarded in the air-conditioning industry, and that’s largely due to being the founder of air conditioning, which Willis Carrier invented back in 1902. The company continues to be a force in the air-conditioning market with designs that focus on being as efficient and quiet as possible. Its Infinity 21 series, the company’s top-end line of air conditioners, boasts a 21 SEER (Seasonal Energy Efficiency Ratio) rating, thanks to a two-stage compressor design that allows the air conditioner to run in a low power setting most of the time. While its top-end AC units are among the most expensive on the market, Carrier does offer affordable AC units with its Comfort 16 series.

The Best Air Conditioner Brand Option: Goodman

5. Goodman

Known for: With recent innovations in technology that extend the life of its air-conditioning units, Goodman has earned a reputation for reliability.
Editors’ Choice: Goodman’s Split System Air Conditioner features the quality construction the company is known for with a filter drying system that extends the life of the unit and a two-stage compressor that adds efficiency.

Although Goodman manufacturing company was founded in 1975, it didn’t begin producing air conditioners until it acquired an HVAC company 7 years later. The company received a boost in 2012 when it was purchased by Daikin Industries, which has since invested heavily in improving the company’s technology.

Much of that focus has been on improving durability by adding such features as guards that protect the AC unit’s vulnerable coils from weather and debris and special filters that keep dirt out of the air conditioner. Those innovations have helped Goodman AC units earn a reputation for reliability and long life.

Rheem acquired the company in 1959; however, Ruud continues to put out cooling equipment in three product lines. Ultra, its top-of-the-line air conditioner, is valued for its efficiency with SEER ratings as high as 20.5.

The company also puts out value-priced AC units that produce a respectable 16 SEER. The company’s units are somewhat larger than others, but that’s because it provides greater access to its parts with its PlusOne technology, which makes the interior of the units more spacious to accommodate maintenance and repair.

VRF allows an air conditioner to automatically adjust compressor speed to save energy, helping to save homeowners money on their energy bills while extending the life of the air conditioner.

The company has acquired several HVAC companies over the years but continues to put out its own line of single-zone, multi-zone, and whole-house units. It produces some of the most energy-efficient air conditioners on the market with SEER ratings as high as 24.5.
