doesn't seem to help?
I should say - it's my computer room - a couple of large towers that generate heat and the A/C does fine on a warm day but not when it should be easy...
Here is a quick lesson on the refrigeration cycle. The compressor pumps refrigerant into the condenser. Which is outside. Under pressure the refrigerant will be a liquid. The process of changing from gas which the compressor pumps to a liquid releases heat. As the refrigerant passes through the condensor a fan cools it. Then, if passes through a narrow hole and enters the evaporator. Passing through the narrow hole reduces the pressure. Heat from the room causes the refrigerant at a lower pressure to boil. Picking up heat from the room. Before the refrigerant leaves the evaporator it is completely vapor. The compressor can not pump liquid. And if liquid enters the compressor it will blow out the valves. So, in order to protect the compressor most window units will have several safeguards to keep liquid refrigerant from getting to the compressor. Once safety device will not allow the compressor to come on when the outside tempurature is below a certain tempurature. The fan will still come on but, you won't get any cool out of it. The vents on window air conditioners are only intended to mix a small amount of air with the conditioned air. When the temp out side is below a certain tempurature just open a window. This time of year I don't run the heat or air conditioner. It is nice to not have to worry about the utility bills.
