Bottom Line

The Compact air conditioner makes use of heavy-gauge steel construction that makes it durable and long-lasting. The single-stage compressor has a single-phase that tends to run at full speed when it cools the house. This compressor is automatic and turns off once your house cools down, and the intake air is not hot. When the air becomes hot again, the compressors get to work again.

The Best of Carrier

Carrier pioneered the air conditioning industry 115 years ago. Carrier is recognized as a world leader in HVAC manufacturing and is known by consumers, commercial businesses and contractors for their innovative technology, energy-efficient products, quality construction, and reliability.

Holds Over 500 Patents in the HVAC Industry

Since 1902, when Willis Carrier first invented the air conditioner, Carrier has introduced new HVAC technologies and patented processes that continue to revolutionize the HVAC industry.

Committed to the Environment and Energy Efficiency

Federal mandates required refrigeration units to switch from Freon R-22, which depletes ozone layers, to chlorine-free Puron R-104A by 2010. Carrier was the first company to use R-410A in indoor cooling systems.

In 2017, Carrier Introduced and Received Energy Star Certification for Its Côr™ Thermostat

This is a smart connected thermostat that allows consumers to check and adjust their thermostat from their phone or tablet. It was among the first companies to receive the Energy Star certification.

In 2018, Carrier introduced the Carrier 9,000 BTU/h single-zone ductless air conditioning system, which is rated 42 SEER, the highest efficiency system in the industry.

Very Selective About Who They Let Represent, Install, and Repair Their Products

Dealers have to be factory authorized and complete continuous training on Carrier products in order to represent the Carrier brand. Less than 5% of HVAC professionals meet the rigorous standards that Carrier sets. Carrier requires that each of its factory-authorized dealers meet high customer satisfaction standards, strict guidelines for insurance and liability coverage and EPA certifications. Carrier oversees product training, installation, and provides technical support and procedures for repair of its units.

Has Been a Favored Homebuilder’s HVAC Brand For Over 10 Years

In BUILDER Magazine surveys of leading homebuilders. Carrier has been ranked the top brand in heating, ventilation, and air conditioning for over 10 years. The majority of builders listed product performance, sustainability features, ease of installation, price, and warranty as the primary things considered when evaluating HVAC manufacturers.

The Drawbacks

The biggest drawback to a Carrier air conditioning system is the price. Being a premium brand, a Carrier air conditioning system can run thousands of dollars more than less name brands for similar types of models. For example:

Carrier 3 Ton Performance 24APA5 16.5 SEER Air Conditioner lists for $2,499.00 (uninstalled and with no additional equipment).

Trane 3 Ton XR15 17 SEER Air conditioner lists for $1,759.00 (uninstalled and with no additional equipment).

Also, Day and Night air conditioners are made by the same company with the same components as Carrier models, but at a much lower price.

Finding the Best Prices

Getting the best price on your air conditioning system starts with doing some research on efficiency, reliability, features offered, and other factors for the major brands you are interested in. If you have some information under your belt, it will make it easier to talk to HVAC contractors about what you are looking for in an air conditioning system. Here are a few other ways to get the best prices.

Correctly Determine the Size of the System You Need

Many people don’t really know how to determine what size air conditioning system they need for their home. You don’t want to get a system that is too big for your needs because it will cool the home faster than it can remove the humidity resulting in a cold, damp air quality that would be uncomfortable. Unfortunately, most homeowners aren’t trained in the engineering procedures that HVAC contractors use to calculate the proper size cooling equipment for your home. So working with a reputable HVAC contractor is key to getting the proper size system for your home.

Time of Year

Many people might think that the best time to buy an air conditioner would be in the winter. While it’s not horrible advice, the fall is probably a better option.

HVAC dealers and contractors are busiest in summer and winter and many people buy both their air conditioning and furnace systems at the same time. The best time to buy a system is when you don’t need it.  Many dealers will offer sale prices during those times in order to generate business.

Don’t Rule Out Tax Breaks

The government has offered tax credits to homeowners to encourage them to purchase energy-efficient appliances because that helps reduce the consumption of energy on a national basis. Check to see if any are available – locally or nationally – when you’re ready to replace your unit.

To qualify for the tax credit, you need to be in possession of a certificate issued by the manufacturer of your air conditioning system. Tax credits can be worth approximately $300 for air conditioning systems that are rated 13 SEER and higher.

What Kind of Warranty Does Carrier Offer?

Carrier air conditioners are known widely for the top-of-the-line support they provide to their customers. However, when it comes down to the warranty, this company starts to lag in this area. Carrier does not offer a lifetime warranty on its products. They do, however, provide you with a limited warranty on air conditioners and even on heating pumps. This limited warranty means, customers get a five-year limited warranty on the compressor and replacement parts.

Furthermore, if you register your product within a time span of 90 days after purchasing your air conditioner, then this limited warranty period extends up to 10 years each. You may also purchase an extended warranty if you want, and this covers not only the cost of the parts but also the labor. 

Company History

Willis Carrier designed the first air conditioner in 1902. Together with several engineers, he formed the Carrier Engineering Corp. in 1915 and opened a factory in New Jersey in 1920 to produce and market their air conditioners to homeowners and homebuilders. In the 1930’s, Carrier moved its operations to Syracuse, NY.

After Willis Carrier’s death, Carrier merged with Affiliated Gas Equipment in 1955, which added the heating and furnace equipment brands of Bryant and Payne as well as Day & Night water heaters to Carrier’s product portfolio. At that time, Carrier moved its operations to Indianapolis, IN due to the lower cost of operations.  

In 1979, United Technologies acquired Carrier but allowed it to continue operations independently. By 2001, Carrier was the largest manufacturer of HVAC and refrigeration equipment in the world.

Carrier, Otis, and United Technologies Fire and Security merged into one subsidiary of United Technologies in 2013.


An air conditioner’s performance depends not only on the quality of its installation and how well it is maintained on the equipment itself. Carrier is probably the most well-known name in home cooling, heating, and refrigeration systems worldwide.  Having pioneered the air conditioner and 115 years of operating history, Carrier has a large market share in the HVAC market.

Although Carrier is at the higher end of the pricing spectrum, they can be expected to deliver consistently reliable and energy-efficient performance with enhanced technological features.
