Help with Heat Pump selection.
I'm in the process of getting quotes for a new Heat Pump for our house in the washington dc area which we just purchased. The house is 12 yrs old, dual zoned. The upper level zone is an attic mounted heat-pump. About 1300 sf.
The local contractors are proposing the following systems (all single stage - variable speed AH):
- Trane 4TWX5030A1 TAM7A0B36H31 $6300 - $700 rebate
($6600 - $700 rebate if it includes 10 year labor.)
2. Trane 4TWX5030A1 TAM7A0B30H21 $5980 - $500 rebate
($6605 - $500 rebate if it includes 10 year labor.)
3. Carrier 25HCC530 FV4CNF002 $6240 - $450 rebate
4. Lennox XP14-030 CBX40UHV-36 $6878 - $300 rebate
Do i go with Trane based on the proposals? Does it matter if AH is 2.5 vs 3 ton if outside unit is 2.5ton?
