What SEER rating do I need for a 2,000 sq ft home?
A 2,000-square-foot home requires a 3.5-ton air conditioner. SEER ratings for air conditioners near this weight range from 13–25. A lower SEER-rated AC system is typically less expensive, but your electricity bills will be higher than with a higher SEER-rated product.

Our Top 10 Picks For Air Conditioner Brands

1. Carrier

Best Performance

Pros and Cons

Pros Has high energy efficiency rates Includes a 10-year limited parts warranty for registered products Some units have sound levels as low as 51 decibels Cons Is more expensive than other brands Cost information requires a salesperson to visit your home


Carrier offers AC units with seasonal energy efficiency ratios (SEER) between 13 and 26.

Its most efficient and best-performing model is the Infinity 26 Air Conditioner with Greenspeed Intelligence. Each Carrier AC includes the option for a five- or 10-year limited warranty, depending on when you register the product.

  • SEER rating: Up to 26
  • Price range: $3,000–$15,000

Why We Chose Carrier

Carrier partners with Energy Star to meet strict energy efficiency requirements set by the Environmental Protection Agency (EPA). This, combined with the company’s low sound ratings and variable speed compressors, results in some of the highest-performing AC units available. Carrier’s boilers and furnaces are equally high-performing.

2. Lennox

Best Energy Efficiency

Pros and Cons

Pros Has the highest SEER rating on this list Uses high-end technology, such as solar panels Is available at popular retailers such as The Home Depot Cons Is more expensive than some companies Varies warranty options by product


Like Carrier, Lennox partners with Energy Star to provide high-efficiency AC units. SEER ratings vary by model, but its SL28XCV unit can reach up to 28—one of the highest rates in the industry.

  • SEER rating: Up to 28
  • Price range: $3,100–$10,000

Why We Chose Lennox

Lennox’s high-end air conditioners feature technology that modifies how they cool based on the surrounding climate, leading to higher efficiency. You can also add the company’s SunSource technology to any of its Signature collection units, allowing you to power your AC by solar panels.

3. Trane

Best Warranty

Pros and Cons

Pros Includes a comprehensive 12-year compressor warranty plus 10 years for other parts and labor Uses a rustproof DuraTuff base pan for longevity Incorporates cutting edge smart-home technology Cons High-end options require a ComfortLink II thermostat to function properly Charges a premium for many of its products


Founded in 1913, Trane offers impressive warranties that make it a secure investment. Its XV20i TruComfort Variable Speed air conditioner uses variable speed technology to continuously communicate with other air conditioning system parts and a Trane thermostat for optimal efficiency.

  • SEER rating: Up to 22
  • Price range: $3,500–$15,600

Why We Chose Trane

Trane includes a 12-year compressor and a 10-year parts and labor warranty, which is more comprehensive than other brands. These warranties help make your investment more secure and long-lasting.

4. Amana

Best Comfort Control

Pros and Cons

Pros Includes a limited lifetime replacement warranty on its high-end compressors Adds features to improve comfort control Has a user-friendly website to search for dealers and find manuals and other resources Cons Performance is average for the company’s pricing Communicating technology is new and can be difficult to fix if it malfunctions


Amana is part of Goodman, the world’s largest manufacturer of heating, ventilation, and air conditioning products and systems. It offers quality AC units backed by a solid warranty. It also features one of the most user-friendly websites, including easy-to-access user manuals and product search tools.

  • SEER rating: Up to 25
  • Price range: $3,600–$11,000

Why We Chose Amana

Though many of Amana’s products have average performance, their features boost your ability to control your home. The company’s ComfortBridge technology uses two-way communication to determine which speed or stage the AC runs on, rather than relying on your thermostat. This allows your HVAC system to use data to automatically adjust to the minimum amount of energy needed to heat or cool your home, lowering your utility costs. Amana also uses a variable-capacity compressor, which improves your humidity control.

5. American Standard

Best Value

Pros and Cons

Pros Offers smart-home technology Has competitive pricing on quality products Uses a network of certified dealers Cons Requires you to buy a high-end unit to receive compressor coverage Has higher sound levels than other brands


American Standard has become a household name in air conditioning since its founding in 1929. The company offers budget-friendly AC units with 10-year limited warranties. It uses a network of certified dealers, so you can buy an American Standard AC with a representative that understands your region’s HVAC requirements.

  • SEER rating: Up to 22
  • Price range: $3,500–$10,900

Why We Chose American Standard

American Standard has many units to choose from, including options for single, two-stage and variable-speed fan motors depending on your budget and desired energy efficiency.

6. York

York began in 1874 producing ice makers, then expanded into HVAC systems once the technology became available. Johnson Controls, which manufactures mechanical equipment globally, now owns the company. York’s AC units combine high energy efficiency and low sound levels. Every model has guardrails to protect the coil and compressor for additional durability.

  • SEER rating: Up to 21
  • Price range: $4,000–$10,000

Why We Chose York

York is the most experienced company on this list. Not only do you receive quality AC units, but also expertise other brands on this list don’t have yet.

7. Frigidaire

Best for Window-Mounted Units

Pros and Cons

Pros Uses an inverter compressor that runs at low capacity and uses little energy Offers high-quality and competitively priced window-mounted air conditioners Includes a 10-year warranty Cons Has a more limited product selection than competitors Possibly more difficult to find a certified installer depending on your location


Frigidaire has become a common household name over the last 100+ years due to its quality refrigerators and freezers. The company brings the same quality to its AC units. Though it’s known for simple, traditional ACs, it also offers a selection of smart-home integration features.

  • SEER rating: Up to 21
  • Price range: $500–$1,082

Why We Chose Frigidaire

Frigidaire offers built-in and portable air conditioners but stands out for its window-mounted ACs. Some options include technology typically reserved for large ACs, such as Wi-Fi connectivity, mobile app control, and inverters that optimize energy efficiency and air circulation.

8. Ruud

Best for Affordability

Pros and Cons

Pros Offers highly competitive pricing on quality AC units Provides an extensive service network Is known for simple, fast maintenance and part replacement Cons Only includes a five-year warranty for the entire AC unit Has similar offerings to Rheem but with additional downsides, such as high noise level


A part of the manufacturer Rheem, Ruud offers affordable full-size AC units. The company’s standard 16 SEER unit, the RA16 Achiever Series, starts as low as $3,000. Ruud’s high-end options, such as its UA20 Variable Speed Econet Enabled Ultra series, offer competitive pricing for smart-home integrated, high-efficiency units.

  • SEER rating: Up to 20.5
  • Price range: $3,000–$6,100

Why We Chose Ruud

In addition to low-cost units, Ruud offers financing options through an in-house financing firm, KwikComfort Financing, with options for zero-interest payment plans. This financing feature stands out given that AC replacement is expensive.

9. Goodman

Best for Longevity

Pros and Cons

Pros Uses R-410A refrigerant, which is less harmful to the environment Includes features for added durability and longevity Offers an above-average warranty for registered units Cons Warranty only covers labor for one year May be challenging to find a certified installer because the company sells units wholesale


Goodman began in 1975 manufacturing flexible air ducts, then expanded to air conditioners seven years later. Though known in the past for relatively standard AC units, its products have improved in quality and durability since Daikin Industries acquired the company in 2012.

  • SEER rating: Up to 24.5
  • Price range: $1,500–$8,000

Why We Chose Goodman

Goodman builds its ACs last, with features including special dirt-blocking filters and rail guards to protect the coils from weather and debris. Goodman backs its ACs with a 10-year limited warranty on parts, a 10-year limited warranty for entire unit replacement, and a lifetime compressor warranty.

10. Rheem

Best for Smart Homes

Pros and Cons

Pros Offers a large selection of heating and cooling products with a focus on sustainability and savings Provides full smart-home integration via its EcoNet products Uses the variable speed Copeland Scroll Compressor, one of the longest-lasting and quietest compressors available Cons Many available products are still too new to know their long-term viability Website lacks customer support


Rheem offers a variety of AC and HVAC units as well as plumbing products with a focus on smarthome integration. Its EcoNet products allow you to fully integrate your home’s heating and cooling systems to maximize comfort and savings.

  • SEER rating: Up to 20.5
  • Price range: $3,100–$6,100

Why We Chose Rheem

Rheem has a smartphone app that lets you control your entire system and receive notifications for maintenance or other issues. The company’s RA20 Variable Speed units are a standout, including EcoNet integration, higher SEER ratings, and eligibility for a $300 energy efficiency rebate. Products like this paired with the company’s app make it one of the best AC brands for smart homes.

What Factors Should You Consider When Choosing an Air Conditioner Brand?

Though cost is crucial when choosing an air conditioner brand, you should consider a few other factors, such as customer service and warranties, before deciding. We’ve listed the most significant factors below.


Your budget is vital in determining which AC brand is best for you. Premium brands cost more because they use newer technology and offer smart home capabilities. You can save money by opting for a standard AC unit if you don’t want or need these features.

The type of air conditioner influences its price, too. For example, a full-size central air conditioner costs more than a smaller option, such as a ductless air conditioning system, also called a split AC unit.

Below are some of the average costs of different AC system types. We’ve also included the costs of vital AC parts, such as a condenser. These are included in the unit cost but can increase or decrease the overall price.

Type or PartCost

Central Air Conditioning






Heat Pump


Split Air Conditioning


Window Air Conditioning


Be aware that some brands, such as Trane, may use their name recognition and long history as a reason to charge higher prices. Though a good reputation is a strong indicator of quality, it doesn’t necessarily mean you should pay more for a comparable unit from a lesser-known brand.

You should also consider that installation costs are not included in the unit price. This costs $1,200–$2,200. 


Warranties help secure your AC investment. Most companies offer a five-year limited warranty for parts but will commonly increase this to 10 years if you register their products online. We encourage you to register your AC unit with its brand to get the most out of your investment. 

A 10-year limited warranty for parts or replacement is standard. A brand that offers a lifetime compressor warranty or lifetime replacement warranty signals the company stands by its products.


Air conditioning technology is continuously progressing. You can buy an AC with all the bells and whistles, such as an internet-accessed monitoring system and smart thermostat. However, more features mean a higher cost. Consider what features and convenience level you want and compare them with the brand’s price tags to find a middle ground. 

Central air conditioning systems that merge your HVAC systems into one unit with a heat pump may cost more up-front. You can save money by opting for a split system, which separates your HVAC system into a furnace for heating and an air conditioner for cooling. However, unified systems with a heat pump are more efficient during summer and lead to lower energy bills, saving you money long-term.

Customer Service

Pay attention to how much customer support is available. A good AC brand should offer various forms of communication, such as an online submission form and direct phone line. Also, take note of whether the company provides certified installers, either in-house or through a network of dealers. 

We recommend researching brands you’re interested in on popular customer review sites such as the Better Business Bureau (BBB). Reading customer reviews will give you insight into the installation process and what it’s like to deal with that brand’s customer service representatives.

How Long Do Air Conditioners Last?

An air conditioner’s life span can vary greatly depending on factors such as its quality, the work performed by the installing technician, your surrounding climate, and how well the system is maintained. The typical home air conditioning unit can last anywhere from 15–25 years. Here are some factors that can shorten your AC’s life span.

Your local climate determines how hard the AC has to work and how low it has to lower your home’s temperature. Hot temperatures mean the AC has to work extra hard to cool the house, which can reduce its life span. An extremely hot and lengthy summer can also reduce the AC’s life span. Learn the annual average temperature of where you live so that you can plan and budget for a new air conditioner accordingly.

Courtesy – climate.gov
Your AC needs to get fresh air, cool it, and distribute it throughout the house without blockages. If there are airflow restrictions, the AC will overwork, which can shorten its life span.
ACs that run around the clock also have a shorter life span because they experience persistent wear and strain. Even with good maintenance and regular tune-ups, the equipment is likely to fail sooner than those that are only used for one season per year.
Lack of HVAC maintenance can cause serious issues over time, which can shorten your AC’s life span. Frequent duct cleanings, filter changes, and regular maintenance are a must to help the AC run more efficiently and last longer.

How Is Air Conditioner Energy Efficiency Evaluated?

Energy efficiency determines an air conditioner’s overall performance and value. Below are two of the most common ways an AC’s energy efficiency is determined.

  • ENERGY STAR ratings: A brand that partners with ENERGY STAR is another good indicator of quality. ENERGY STAR uses strict guidelines to certify AC units. For example, the unit must have a SEER rating of 14.5 or higher. It must also have an energy efficiency ratio (EER) rating—a more standardized measurement than SEER—that uses 8% less energy than conventional AC models.
  • SEER rating: Seasonal energy efficiency ratio (SEER) ratings are the ratio of an AC’s cooling output over a typical cooling season divided by the energy it uses in watt-hours. A SEER rating is calculated over an entire cooling season using a constant indoor temperature and a variety of outdoor temperatures ranging from 60℉ to over 100℉. Be aware that a SEER rating is the maximum efficiency rating. Your unit’s efficiency could be lower depending on your home’s conditions, such as insulation and windows. Any SEER rating above 13 is considered good. The average rating is 16, and anything above 20 is top-of-the-line. Units below 13 are likely low-quality.

Our Conclusion

The best air conditioner brand depends on your budget, needs, and wants. Carrier air conditioners are some of the best-performing, while Lennox has one of the highest SEER ratings and best energy efficiency scores. Brands such as Trane or American Standard may be a better fit if you’re looking for something more affordable.

One of the biggest mistakes homeowners make when shopping for air conditioners is not obtaining multiple quotes from HVAC contractors. We recommend getting at least three quotes from different brands to compare costs, warranties, and additional features.

  • Energy Star certification (10 points): We award more points to companies with Energy Star-certified products.
  • Reputation (10 points): We factor in how each company is scored on the Business Better Bureau (BBB). We deduct points for any alerts or pending lawsuits.
  • Customer service and resources (20): We consider each company’s available customer support and resources. This includes whether the company offers a user-friendly product search tool, FAQ section, pricing guides, online manuals, and a mobile app.
