Most Likely refrigerant charge is low -- compressor will not engage unless system has proper pressure
sounds like he bypassed the switch for the low refrigerant shutoff , check freon level
Its helps in oil return if the refrigerent line is too long
Simplest answer is that the refrigerant (freon) may have leaked out. Also could be: loose wire - faulty A/C relay or fuse - bad compresser - you need to have it looked at and the possibilities narrowed down.
yes, but you will overwork your compresser and you will have to change your txv
usually the refrigerant you have pumped out of the system is contaminated (either liquid/air) contaminated refrigerant is less efficiant and will lead to a short system life. refrigerant is works kind of like the rain in a water cycle. The system starts at the compresser (the heart of the system) pushing refrigerant in to the condenser (like condensation in the clouds) condensing to a liquid and heads toward the metering device (raining) The metering devise rapidly lowers the pressure of the system into the evaporator (get the picture already?) where the refrigerant collects the heat in the refrigerated space and boils into a vapour releasing it to out side the refrigerated space. obviously there is more detail then this but thats the basic operation.
Yes
refrigeration processes which include condensation-evaporation of a refrigerant and compression in a compresser- expansion in a turbine or an expander. A simpler way to think of it is to think of the refrigerant as a sponge. It soaks up heat inside, and wrings out outside. If you've ever put you hand over the condenser outside you'll notice the air is very warm. That is the heat from inside your house
If you're talking about the air conditioner compressor, it probably won't click on because the system is low on refrigerant. Other causes could be a faulty clutch, a bad relay or switch, or blown fuse.
