This routine allows heat to be moved in the inside of the home to the outside of the home. A special liquid called a refrigerant is employed in this process, as it goes outside, where heat released and is absorbed. The refrigerant changes in state between gas and liquid during this period. This liquid is passed via an expansion device that shifts the liquid directly into a low-pressure mixture of liquid/gasoline. This is why a number of the air conditioning units have water droplets or “perspiration” on the gear that is sticking on the exterior. The remaining liquid in the rings that are interior absorbs warmth from the interior atmosphere, which turns into a low-temperature gas cooling the interior atmosphere.

Tape a tarpaulin or garbage bag that is large underneath the unit to get the water as the snow thaws. After the snow thaws, the unit is dried by hand and allow it to stand to dry for 24 hours. Inspect the unit to ensure it’s dry before switching the power back on.

Check the filters to the in-door device. Make sure the filters change every 90 days. Some filters allow airflow in only one direction. Make sure the atmosphere can stream through the filters and to the machine.
