Carrier Air Conditioning Specifications

Consumers are often at the mercy of their air-conditioning salesperson when it comes to understanding what they need in an air-conditioner. Manufacturers list specifications for performance, capacity, refrigerant, and SEER, but what does that mean? Having a basic idea of what typical specifications mean is your best defense in detecting deception from a salesman. Since Carrier Corporation had sales of 11.4 billion dollars in 2009, learning about their specifications is a good place to start.


Learn about Carrier specifications to make an informed purchase.

Performance covers SEER and warranty.

SEER stands for Seasonal Energy Efficiency Ratio. It measures the cooling efficiency of your system. The higher the SEER the better. Carrier system's SEERs start at 13 and can go up to 21. SEER is important because the more energy efficient your air-conditioning system, the cheaper it is to run.

Warranty information is also included in this section of the specifications.Carrier warranties vary, but all Carrier systems come with a ten-year parts warranty.

Energy Star

If an air-conditioning system has the Energy Star seal, you are going to hear about it from your salesperson. Most of Carrier's units are Energy Star qualified. Energy Star ratings mean the equipment meets energy efficiency standards set by the Environmental Protection Agency. Energy Star air-conditioners save on electricity costs. Replacing a system that is 12 years or older with an ENERGY STAR qualified model could cut your cooling costs by 30%, reports the Energy Star website.


Sound refers to how noisy the system will be inside and outside your home. Most systems today operate fairly quietly. Some factors that make a unit loud are bearing issues in the compressor, the type of compressor cover, and the blower speed (a variable speed is the quietest). Carrier lists "Quiet Level" in its specifications and measures the noise in decibels. On average, Carrier's units make 72 decibels of noise.


Controls refers to the thermostat that may or may not come with the system. Carrier has thermostats that range from simple (Carrier's Comfort Non-Programmable Thermostat) to Carrier's high end (Infinity Thermostat.) At minimum, the thermostat will be a digital thermostat. Programmable thermostats are ideal, because they add to the efficiency of your unit and give you the ability to program cool and heat settings by time of day.


The technology specifications cover refrigerant, compressor type, and capacity in tons. These are the big things to know about when buying an air-conditioner system.

Refrigerant means the type of freon the system uses. No system sold today will use R-22 (the most common used before 2009). Freon is now manufactured to be environmentally friendly thanks to the EPA and the Clean Air Act.

The compressor is the heart of your air-conditioner. Without it, the system could not run. Most residental air-conditioners run on a scroll compressor.

Capacity is measured in tons and refers to the size of your unit. A bigger capacity does not mean a better unit. Capacity is determined by the size of your house and other factors such as your insulation. It is very common for air-conditioning companies to sell consumers oversized units. Get several estimates. Also, keep in mind, the greater the capacity the lower the SEER.


Aesthetics seems unimportant when choosing a machine that can cost 3,000 to 20,000 dollars in an average sized home. Aesthetics do have some value to the overall performance of an air-conditioner. Things to look for on Carrier air-conditioners are what protection it has against corrosion and ware from outside elements, how it is constructed for durability and how well constructed the coil guard is.
