I am replacing a 10 seer 3ton a/c system with a 15 seer 3ton. The existing
lineset is ~80ft, of which 30ft is inaccessible.
for full ratings, Goodman requires the use of 1 1/8" suction line, while the
existing line set is only 3/4" x 3/8"
is it worth while to go ahead and replace the 50' run with 1 1/8" even
though the middle 30' will still be 3/4" ?
customer states that condenser has already been replaced once after only
five years. The existing condenser is dead after ~8yrs. I advised replacing
complete line set, but cost will be prohibitive to customer (still probably
less than replacing the condenser after 8yrs).
I can relocate the condenser to the south side of the house which will
reduce the run by an additional 25 to 30 feet, however it will get a lot
more heat on that side of the house.
