Lennox add on cooling (Air Conditioning)

If you have a warm air system, it is a relatively easy task to add air conditioning thereby offering you all year round comfort.

To add air conditioning to your system you simply need to fit a DX evaporator coil to the supply side of your warm air heater and link this to an external condensing unit. The external condensing unit supplies a refrigerant to the DX evaporator coil which removes heat from the air in the same way as a domestic refrigerator cools your food.

There are two types of DX evaporator coil used in domestic applications one for upflow systems and one for downflow.  There is also a third option which is a horizontal DX evaporator coil but this is rarely used in domestic applications in the UK although it is frequently used in commercial applications.
