Inside air conditioning systems are liquid/gas refrigerant. There are two types of this refrigerant available for use, R-22 (more commonly known as Freon), and a newer alternative R-410A.

An air conditioning system does not consume refrigerant, but reuses it. As long as there are no leaks in the refrigerant circuit, there is no need to ever add more refrigerant to an air conditioning system.

Although R-22 is an effective refrigerant, if it is released into the atmosphere it can contribute to the depletion of the Earth’s ozone layer. The EPA has mandated the phasing out the use of R-22. It is being replaced by R-410A.

As of 2010, manufacturers are required to make all new air conditioners with R-410A. However, R-22 is still available for sale in existing pre-2010-manufactured equipment, and for use in servicing existing R-22 equipment. By 2020, R-22 will no longer be manufactured, but will still be recycled and available for sale.

There are two main types of connections for HVAC products brazed and flared. Brazed connections are typically used in standard split systems, and flare connections are typically used on mini splits and can be connected using a wrench.

The outside diameter of the liquid line pipe (the inside diameter of the connection on the equipment).

The outside diameter of the suction line (the inside diameter of the connection on the equipment).

Different types of air handlers are available depending on your needs.
Wall Unit: easiest installation, lowest cost.

Ceiling Flush Mount: less visible, centralized air distribution, more complex to install.

Concealed Ducted Unit: mounts under floors or above ceiling, uses ducting to heat and cool multiple spaces.

Heat Console: mounts at floor level on vertical wall for better heat distribution. Reversed air direction in cooling mode for better cooling performance.

Floor Ceiling Console: mounts either on vertical walls or horizontal ceilings for maximum flexibility.
