    Ryan:

    Our summer electric rates are 11 cents generation plus 2.37 cents distribution plus .4 cents transmission = 13.77 cents per kw-hr. Our electricity is not cheap (72% increase) since deregualtion without competition arrived in 2007.

    The system with the highest Energy Efficiency Ratio (EER) will be the cheapest to run.

    What are the model numbers of the condensers and air handlers?

    Since you are getting a system with all the bells and whistles, I hope you are considering a 10 year parts and labor warranty. Those fancy systems are great until something breaks after the standard labor warranty (1 to 2 years) and parts warranty (5 to 10 years) have expired.

    Take care.

    Wasn't really considering the 10/10 warranty. The warranty the proposal states is 10 years on all parts for either the Xl15i or the Evolution 16 as well as 2 years labor from the company.

    XL15i combo: 4TWX5048 + 4TEE3F49
    XL16i combo: 4TWX6048 + 4TEE3F49 (or 4TEE3F40?)
    Evolution 16 combo: 286ANA048 + FE4 size 005

    XL15i combo: 4TWX5048 + 4TEE3F49

    48,000 btu cooling, 11.8 EER, 14.25 SEER, 50,000 btu heating at 47F, 8.7 HSPF, 31,200 btu heating at 17F. ARI# 1385065.


    XL16i combo: 4TWX6048 + 4TEE3F49

    47,500 btu cooling, 11.5 EER, 15.5 SEER, 43,000 btu heating at 47F, 9.1 HSPF, 27,600 btu heating at 17F. ARI# 1106632.


    XL16i combo: 4TWX6048 + 4TEE3F40

    45,500 btu cooling, 11 EER, 15 SEER, 41,500 btu heating at 47F, 8.55 HSPF, 24,400 btu heating at 17F. ARI# 1106630.


    Evolution 16 combo: 286ANA048 + FE4 size 005

    47,000 btu cooling, 11.6 EER, 15.8 SEER, 47,500 btu heating at 47F, 9.1 HSPF, 27,600 btu heating at 17F. ARI# 1250424.


    The 15i has outstanding heating btu and cooling btu capacities. The 16i is poor in heating capacity. The Evolution 16 has good numbers also, but not as good as the 15i.

    Take care.
