I just got an estimate from Sun Kool for the Carrier Infinity Greenspeed 4 ton. $14,951. The same in a 3 ton from Sun Kool $13,146. Manual J is the industry standard for sizing a heat pump. There is free software on the internet like CoolCalc Manual J .

The salesman claimed to me I would save 35% on my heating and cooling portion of my energy bill, not on my energy bill. I spent $103.00 on cooling in June and in October I spent $8.00. This is according to SECO. In the winter months I may not even turn the heat on.

Rule of thumb, The monthly savings per 1.0 unit increase in SEER = 15.6 kWh × $0.14/kWh = $2.20 per month. My present Carrier installed in 2009 is 15 SEER so if I go to a 20 SEER $2.20 X 5 =$11.00 per month. X 12 = $132 per year and for 10 years $1320.00. Is that on the low end or on the high side? I hope that is on the low side.
