Overall Efficiency <p>Efficiency within a model group will tend to vary by the size (capacity) of the unit. Some products, like furnaces, may also be affected by installation orientation (horizontal, upflow, or downflow) or even by the nozzle used in installation, as is the case with boilers and oil furnaces. The efficiency of an air conditioner or heat pump can even be affected by the furnace or fan coil it relies on inside the home to move air. Products that fall into the “Select sizes ENERGY STAR<sup>®</sup> qualified” category include within their model group some non-qualified units due to either size or potential installation factors.</p> info

Researching air conditioner systems, but not sure what to look for? Carrier can help you find the best cooling system for your home indoor environment.


Different central air conditioner products affect your comfort and the consistency of indoor cool air. A single-stage air conditioner is the most basic model, with airflow on or off. A two-stage model offers high- and low-stage cooling as conditions require and therefore can provide enhanced comfort levels. Variable-speed AC systems include premium comfort features such as multiple stages for more precise temperature control and more consistent comfort.



Reducing the humidity levels within your home can dramatically improve your comfort and indoor air quality. To help cool your home, your AC unit pulls heat and humidity out of indoor air, using your system’s blower to circulate the air. Models with a variable-speed compressor provide excellent humidity control because they can operate at lower speeds for longer times. So, they spend more time pulling humidity out of the air than models with a two-stage or single-stage compressor.



Air conditioners with variable and multi-stage compressors provide ultra-quiet operation compared to models with single-stage compressors. In addition, models that include sound blankets and our Silencer System II™ design can further reduce noise levels. If your AC unit is located near a bedroom window or patio, for example, sound performance might be an important feature to consider.

Air conditioners are rated by their seasonal energy efficiency ratio (SEER2). The SEER2 rating of an air conditioner is much like miles per gallon (MPG) for a car: The higher the SEER2 rating, the more energy efficient the system.

Heating and Cooling Basics

What is Central Air Conditioning and How Does It Work?


Carrier offers a variety of AC units to fit any budget and to keep your home comfortable. Your local Carrier expert can help you select the best AC system to fit your needs and provide proper HVAC installation services. No ducts? No problem. We also offer ductless mini split systems.


We know that not every house is the same. That’s why we offer a variety of different types of Carrier air conditioners to meet the needs of your unique home. Our central air conditioning systems include an air conditioner and an indoor unit with an AC evaporator coil, typically installed in a utility closet, basement, or attic. The blower fan of the indoor unit will distribute conditioned air throughout the home through ductwork within the walls of your home. In some climates, people will select heat pumps for the outdoor unit and pair them with indoor air handlers because they can also provide electric heating which is ideal for some regions.

Carrier also offers ductless mini splits which are flexible cooling solutions that doesn’t require ductwork. Mini splits are also an energy efficient option and don’t obstruct a window, unlike a bulky window air conditioner.

Air conditioners are available in a variety of capacities, typically ranging from 1.5 tons to 5 tons. The size and layout of your home play a crucial role in determining the appropriate unit size. Whether your home is 2,000 square feet or exceeds 5,000 square feet, there is a suitable air conditioning solution for most every situation. To ensure you select the right size air conditioner for your home, we recommend scheduling a consultation with a local Carrier expert.

Regardless of your situation, you can have confidence that Carrier has an AC system that can meet your home comfort needs.

We have introduced all new air conditioners that are compliant with the 2023 Department of Energy minimum efficiency requirements as part of our ongoing commitment to creating energy-efficient HVAC systems. These new air conditioners have also been reviewed and tested under the new 2023 testing procedures and have SEER2 and EER2 ratings published.

Effective January 1, 2023, the Department of Energy (DOE) is requiring new testing procedures to determine efficiency ratings on split system air conditioners. The Seasonal Energy Efficiency Ratio (SEER and SEER2) and Energy Efficiency Ratio (EER and EER2) are two efficiency standards set by the DOE for HVAC systems. These ratios are calculated by using rigorous testing procedures that are determined by the DOE. The Department Of Energy updated these air conditioner efficiency standards to SEER2 and EER2, on January 1, 2023, to account for more accurate testing conditions that better represent actual operating conditions and are required for any equipment manufactured and installed on or after January 1, 2023.


*Depending on model combination. Based on laboratory testing of Carrier’s Infinity® 26 air conditioner model by Carrier engineers in Fall 2019 and AHRI sound level data for competitors’ variable-speed outdoor units, published as of December 2019.
