I’m building a new house and the contractor’s original quote is for Carrier units- Down using 13 seer AC (24abbb348) 91% Gas furnace (58MCB080); up using 2 Heat Pumps (25HBB324 and 25HBB318) due to foam insulation. We are in piedmont NC he said the HP would be more efficient and comfort would be fine. The last heat pump I was in the mid-1980’s.
Contractor has given me 2 options that add about 20% to cost. Downstairs he would go to a Hybrid HP 15 seer and 94% furnace. Didn’t get exact model but he thought 25HCCxx and a 58 MECxx and also going to 15 seer on both HP upstairs. He indicated the warranty went from 5 to 10 years and would go from the “base” model to the “comfort series”
Is it worth the difference to go to 15 SEER and the Hybrid Heat Pump? Also what kind of payback would be expected? Paying 8.6046 per KWH.
