Replace w/ high SEER heatpump or AC economics
Replace w/ high SEER heatpump or AC economics
(OP)
Can somebody show me why I should buy a SEER14 HP if I presently use a SEER 9 and my electric rate is $0.16/KWH and the average ambient outside temp during summer is 80 for 4 months (location southern CT). Or should I just consider staight A/C and forget the heatpump. If possible please point me to the calculations needed to make the decision including outside winter temps ( I think 40 degrees would be reasonable).

To do the calc you will need hourly temperature data, total UA of your house and occupancy pattern.
This site:

has a table of "typical" potential savings, and a link to a calculator

I didn't download it, but it might do exactly what you need. If not, one of the other hits probably will.
