TXV hot swap

[Stumbo]

I have done this once with good results. In the perfect world you would have a filter-dryer already in the lineset to clear your mind.

However, I must say, I have only seen 1 410a TXV actually fail.

it you have the change the txv because it is malfunctioning possibly from debris changing the lld would be a good thing.

damm i must be slow not sure if it could change it out with presssure remaining on both sides

i guess if you leave enough liquid in the system and are not using a torch - i hate that- and have your buddy hold his thumbs over the exposed ends while you are in between his legs it might work.

i probably have bad luck with these things so i'll recover and my buddy has short arms

I've never seen a 410a valve fail and have only seen handfull of 22 valves (on residential split systems) fail. All were 15-30 years old and all had lost the charge in the powerhead. All were working as good as new after simply installing a new powerhead

Do you work on residential heat pumps? Do you verify that they hold the specified superheat? Units in Florida make it to 15 years occasionally.

you must not work on york/unitary products group equipment then because i see 410a txv fail more than they should
