Air Conditioning Heating: Heap pump

Air Conditioning Heating: Heap pump: "Most air conditioning systems these days are heat-pumps which means they are capable of heating and cooling. This has been made more effective with R410a gas which has a higher pressure and the correct heating properties thus producing more air conditioning heating power. Air conditioning heating units these day produce astonishing efficiently with some air conditioning manufactures producing 6x input, usually called COP Technically the air conditioning unit produces heat by reverse cycle. The condensing unit (outdoor coil) becomes the evaporator taking heat from the outside air and blowing cold air from the coil. The evaporator (inside coil) then takes cold out of the indoor air and blows heat in. Air conditioning heating is by far the most efficient way of heating.
