Has the refrigerant messed up your vacuum gauge?

[@AaronPowellvox]

Any time I install American standard or Trane I like to remove that side panel to verify that none of the pipes are touching anything. Especially the ones that go under the coil to the compressor. I like that RLS setup.

Can a 3.5 ton unit be reduced down from a 7/8 line to 3/4 suction line? The old unit is 3 ton with 3/8 and 3/4 lines.

[@Balticblue93]

Read the manual but the answer is yes, you can reduce to a 3/4" suction line on a 3.5-ton unit.

[@AaronPowellvox]

You will lose efficiency but it will work. It just won’t work as well because it won’t move as much refrigerant. Different manufacturers are different and the information is usually I the installation guide.

[@Balticblue93]

@@AaronPowellvox Not in this case you won’t lose efficiency by dropping from from 7/8th to 3/4. As long as the correct sized piston or TXV is used and the charge is set correctly, a half-ton difference isn’t enough to drop efficiency. Plenty of refrigerant will be flowing especially with a slight larger piston or 3.5 ton TXV. The actual charge will need a bit more dialing in but there isn’t a big enough difference to change efficiency. If anything, it might improve it.

The efficiency is probably negligible, I do it and I have no issues

non brazed joints? i feel like thise are more likely to leak than a properly brazed joint
