Help Choose Repl Gaspack: Trane or Coleman
Replacing my dying 20+yr old roof gas-pack 2.5t Carrier 48NLT030300 in dry-hot Central CA. IMO, it is sized OK (maybe not perfect) as it heats just fine and cooled well (when it had proper amounts of r22).
3ton replacements (all Manuf. 10yr parts/labor, 20 hx):
1) Trane 14seer gas dual pack #4ycy4036B1075a (My Initial Choice)
2) Coleman 14seer DAYQ-F036N070 ($650 3) Coleman 16seer DBYX-F036D110 ($300 > #1)
* All quotes from same (preferred) vendor.
No special needs (filtering for allergies, reduce humidity, etc). My ducting is old, but is still solid (I've checked every inch and Mastic sealed + metal tied all joints) with 14% duct-test leakage. We'll be increasing the short return duct by as much as the space will handle (probably 4" more) and adding one vent, so the additions seem OK with the latest ManJ results for the 3ton.
Opinions? I had chosen Trane as the replacement for my old Carrier, but I don't know much about Coleman.
Thanks in advance,
