Split Air Conditioners - Refrigerant Coil.

An air conditioner seems as if it cools your home's air, but it actually makes your home less warm by removing heat from the indoor air and transferring that heat to the outdoor air.

Heat is extracted from the home by passing indoor air across a refrigerant coil in the indoor unit. Refrigerant lines then carry the heat to the outdoor unit, where it is released into the outside air. The cooling cycle continues until the indoor temperature reaches the thermostat setting.

Ductless Air Conditioners - Growing Environmental.

Refrigerants are what make air conditioning possible. Contained within the coils of an air conditioner, these liquid agents cool and dehumidify indoor air. For years, the most common refrigerant used in air-conditioning systems was R-22.

In response to growing environmental concerns, production of systems using R-22 refrigerant is being phased out. Lennox has led the way in the manufacture of cooling systems that use chlorine-free R-410A refrigerant. Because R-410A contains no chlorine, it is considered ozone-friendly.

Mini Split Air Conditioners - The Alternative.

The R-410A used in our newer systems cannot be substituted into existing systems designed for use with R-22 refrigerant. Many manufacturers offer "alternate" refrigerants like R-407C, R-438A and R-422, claiming they can be used in existing R-22 air-conditioning systems. Changing from R-22 to an alternate refrigerant can damage equipment and compromise overall system performance.

"Variable speed" refers to the fan motor inside the air handler the indoor part of an air conditioner that moves cooled or heated air throughout the ductwork of your home. An air handler is usually a furnace or a blower coil.

Unlike conventional single-speed motors, a variable speed motor runs at a wide range of speeds to precisely control of heated and cooled air throughout the home. Better airflow control has several benefits:
