linesets

Not to fan the flames in the other HVAC thread!
Can one upgrade the entire system/equipment from the SEER from 30 to 80 and not need to replace the line set (assuming it is in good condition)?

80?

80?

It's REALLY good!

SEER or EER has nothing to do with the lineset. If sized right and in solid condition, it's fine. What the frig.

Old line sets would want to flush to clean out existing oil and any debris.

Not sure what you're asking about SEER-wise, but if you are going like for like in tonnage then probably will be good with the old line and their size. My old 3 ton unit (13 SEER) was replaced and it had lines that were buried (pier and beam house). The line size was compatible with the new unit (21 SEER) and besides having to get a ground hole bored out just for the heat pump due to AC run not having a ground (and also being buried) there was not much the tech did besides cleaning, extending slightly and re-insulating the parts of the line exposed to the old line set.

80 SEER? Let me know when you get this figured out - I want in!
