Currently have 3.5 and 2 ton Carrier units. Both are 11 years old. 3.5
ton is shot. 2 ton is close. Coils look ok.

Plan on staying in the house for at least 5-7 more years.

Four questions:

1) Trane or Carrier........... leaning toward Trane

2) It was recommended that I replace a Carrier coils that are 11 years old
to match the new outside Trane units (how long do the A/C coils typically
last) and the coil lifetime is not that much longer than the outside units

3) Is this a good price for a Trane 12 Seer XR12

4 Ton Unit
4 Ton Replacement Coil (high efficiency)
2 Ton Unit
2.5 Ton Replacement Coil (high efficiency)

$5,900 installed if buy same time or $3,500 and $3,000 for 3.5 and 2
ton separately

4) Trane offers a 5 or 10 year extended warranty that can cover parts or
labor or both parts and labor transferable. Is this advisable?


Thanks
