Understanding Air Conditioner Technology

Efficiency

SEER

SEER stands for the Seasonal Energy Efficiency Ratio and is the measure of efficiency by which the cooling process of air conditioner or heat pump systems are rated. The higher the SEER number, the greater the efficiency, and therefore the greater the energy savings. Today, U.S. regulatory agencies require all new products to have a 13.0 SEER rating or better. Carrier products offer air conditioner systems that can achieve ratings over 20 SEER.

Compressor Technology

Single-Stage

Single-stage cooling means that the air conditioner or heat pump has a compressor with a single level of operation.  The compressor is either off or on depending on the cooling demands of the home.

Two-Stage

Two-stage cooling means the air conditioner or heat pump has a compressor with two levels of operation: high for very warm climate and low for milder temperatures. Typically the low setting is adequate to meet household cooling demands 80% of the time.  A compressor operating at the low setting will run for longer periods of time and produces consistent even temperatures throughout the day.  Longer cooling cycles translate to quieter, more efficient operation.

Variable-Speed 

Unlike conventional single or two-stage motors, a variable-speed compressor runs at a wide range of speeds to precisely control the flow of heated and cooled air throughout your home.  A variable-speed compressor is able to ramp up and down it’s performance in small increments in order to deliver maximum comfort and efficiency.

Freon-22 vs. Puron©

Freon-22 vs. Puron©

According to the Clean Air Act of 1990, Freon-22 and other refrigerants commonly known as HCFC’s, will be phased out of use in the near future. In 1996, a cap was placed on refrigerants that use HCFC’s, and are known to be harmful to the ozone layer.  After 2010, the manufacturing of new air conditioners that use Freon-22 will be prohibited, and in 2020, production of Freon-22 will be banned.

Carrier has been designing and testing heating and cooling equipment that uses Puron©, a refrigerant approved by the EPA to replace Freon-22.  In fact, Carrier has been offering Puron©-based systems in homes like yours since 1996, developing a complete line of products using the world’s first, long-term solution to ozone depletion.
