Re: Removing Mini-split A/C-Heatpump systems

said by 49528867:

I am not going to tell you how to do it, but I will tell you how it has been done.

Close the high side valve and leave the low side valve open, run the compressor for about 45-60 seconds (you can hear the compressor load up when it is reaching the end of the process) then while the compressor is still running close the low side valve and immediately shut down the compressor.

Crack open the low side fitting and allow the pressures to equalize (chances are you will have a zero pressure or a vacuum) once that is complete remove both lines from the condenser and tape the ends of the tubing shut to preclude the entry of contaminants.

Move the unit to the new location reconnect the tubing fitting up the high side coupling nice and tight but leaving the low side coupling finger tight, slowly open the high side valve allowing refrigerant to flow into the evaporator to purge the tubing toward the low side through the loose fitting for about 10-15 seconds of flow then make up the low side coupling nice and tight.

Power the unit up and test for proper charge by noting a cool and wet low side after the unit has been cooling awhile.

Now you’re all done.

Corrected valve error.

that is the way homeowners were allowed to do it years ago, now it's called releasing an ozone depleter into the atmosphere, as you'll lose some freon into the air. the OP didn't want to buy any.

Yes and that pony has been well beaten.
