Split AC Help
Posted on 8/30/23 at 10:00 pm

Been in a house a year that has an old LG split AC that doesn't work. Supposedly the main circuit board was damaged and LG no longer made them so I bought the house and was going to worry about it later. I would like to get rid of the unit inside and out. I started researching and found that AC units are to be drawn down to capture the bad stuff. Most of the info deals with the process, but you have to be able to power on the AC.
Any tips on how to cap lines safely to uninstall the outside and inside untis. Thanks.

Though I’m somewhat confused by your question, a tech doesn’t need a working HVAC to recover the refrigerant. They have a pump that is used to recover the refrigerant which required by federal law. Then the line set can be capped if you going to wait a while before a new unit is installed but then why would you do that? Why would you not install a new unit as the old unit is removed.
Are you thinking of doing this yourself? Violation of Federal law to do this without a EPA 608 certification.
No possibly of finding a used but working circuit board somewhere?

Yes, I looked for a used board and wasn't able to find anything. We honestly probably wouldn't use the AC even if I could find one. At this point I am trying to remove the unit and clear the space for something else. I'm aware that an HVAC guy will have a pump, but was trying to avoid paying the ridiculous service fee.
I know that I can't just vent this as its a federal violation and comes with a stiff fine. Most topics I've found has you running the unit and being able to trap the refrigerant inside the unit and then shutting the valves thereby trapping the fluids.

Should be a valve on the outside portion where the line goes in. Close that and capture what's in the compressor. Then just remove the rest.

Sure that’s often done for a working unit with perhaps a leak that needs repair/replacement, say an evaporator coil with a slow leak that needs replacement, pumping the existing refrigerant down with, and trapping it in the compressor, then releasing back into the system, with a top off, once the repair is made.
I haven’t a clue what it would cost to do what you want done - have you gotten estimates?
