Question about Heating & Cooling
Hi, i need to remove and relocate 12000BTU split air conditioner without releasing gas (if possible) from the system without calling a contractor to regas the unit. I am very technicaly minded, i installed the system myself without any problems 1 year ago.
Tech. assistance in this matter would be highly appreciated.
The simplest way of explaining this is as per the following. On your outdoor compressor unit there should be two pipes, one smaller diameter [high pressure] and a larger diameter pipe [low pressure]. Turn your A/C on inside the house and then shut off the smaller diameter pipe. Run the unit for a around 3 to 4 minutes and then check if the cooling is reducing from the unit inside the house. When you feel room temperature air [not cool] being emitted from the indoor unit shut off the larger diameter pipe and turn off unit. Isolate electrics, disconnect A/C piping and immediately seal the piping with good quality tape to prevent egress of dirt. When re-installing a quick purge of gas is usually only required to clear the lines if they were sealed properly and kept clean. Ideally running a vacuum pump is recommended but if care was taken then it may not be needed, as in many of my installations.

If the unit has king valves you can close the liquid line and pump the refrigerant into the condensing unit. Do not pump the unit into a vacuum. Any remaining refrigerant should be properly recovered by a EPA licensed tech.
Move the unit, reconnect (taking care not to allow any moisture or contamination into the lines) and evacuate the refrigerant lines and the evaporator down till it holds 500 microns for 10-15 minutes.
The refrigerant can then be released back into the system.
Hope this helps.

Matt is correct! your compressor could possibly be a scroll. DO NOT RUN THIS INTO A VACUUM!
