    Hmm, all this would be an educated guess, but I would say...

    R-19 walls / R-30 ceiling
    Front of house faces South

    7 windows on South side for approx. 87 sq. ft.
    2 windows on West side for approx. 25 sq. ft.
    3 windows on East side for approx. 40 sq. ft.
    3 windows and 2 sliding doors on North side for approx. 117 sq. ft.

    All windows are 20 year old wood framed single pane Andersons.

    I have no idea what the local electric rates are. I just pay the bill and shed a tear each month. But does this chart help at all? Got it from here.

    Effective January 2006

    Residential ----------Average ----Detailed Price
    Rate Classes -------Price to-----to Compare*
    ------------------------Compare------(cents/kWh)
    -----------------------(cents/kWh)---

    Residential (R)---- 6.70 --------up to 500kWh 6.57
    ----------------------------------------over 500 kWh summer 7.38
    ----------------------------------------over 500 kWh winter 6.57


    Residential ------- 5.40 --------up to 500 kWh summer 6.82
    Heating (RH)---------------------over 500 kWh summer 7.65
    ----------------------------------------up to 600 kWh winter 6.82
    ----------------------------------------over 600 kWh winter 3.79


    Off-Peak (OP) ----- 1.96 --------all kWh’s 1.96

    See note 1 below



    CAP Rates ----See note 2 below-----See note 2 below


    *Summer months are from June - September.
    *Winter months are from October - May.


    Note 1: Off-Peak service customers who choose to shop, must receive generation service from their supplier for their Off-Peak account along with the energy for their regular rate account (i.e. R or RH).

    Note 2: CAP D and E Rider customers, will continue to receive their CAP discount, as well as have the opportunity to shop for another electric supplier. CAP Rate customers can call at 1-800-494-4000 to obtain the price to compare for their rate class.

    Thumbs up VERY, VERY FAVORABLE Rates

    __________
    I guess I missed overall house dimensions previously
    Base house dimensions are
    ~44' x 30' ? 2 story ?

    Window summary is Reasonable!
    15 single-pane windows totaling 269 sq. ft.
    I would have expected to see a slightly larger number of windows but, the extent of glass use in different regions of the U.S. is unique to the area (less in the North).

    I believe that the PECO rate RH
    would be most beneficial with the

    $0.0379/kW-Hr for the Winter Heating.

    You need to check your current PECO plan selection
    and convert to this plan by late September.

    @ < 4 cents per kilowatt-hour for >600 kWh,
    THAT has got to be
    'about as good as it gets'
    for the consumer
    ( or perhaps TOO Good to be true for the out years)
    **************************
    ESPECIALLY with respect to comparisons
    to natural gas & oil.

    I would like to know how PECO can offer that rate.
    No surcharges are mentioned that
    I noticed on an initial review.

    It will take a while to develop a comprehensive energy and cost analysis for your specific residence, equipment selection and PECO rates. I will get back to you later today or Sunday via this HVAC-Talk posting.

    Other electrical needs
    (hot water heater, TV, PC, lights, refrigerator, freezer, clothes dryer, dish washer ... as applicable )
    would likely be
    close to 500 kW-Hr for many households.

    Dan, thanks for all your help. I really appreciate it. I have grabbed some more realistic numbers now that I've had a minute if it's helps. I hope they are not too far off what I said and I really hope it doesn't cause you any aggrevation.

    - House is 2300sq. ft. I forgot to remove the garage area.
    - Dimensions are 34'x 30' for 2 storys. And 20' x 13' for 1 story. (Cathedral ceiling)
    - Windows and Doors sq. ft. is...
    ... North Side - 100 sq. ft.
    ... East Side - 34 sq. ft.
    ... South Side - 68 sq. ft.
    ... West Side - 28 sq. ft.
    ... And 2 brand new Velux Skylights with UV coatings on the North side are ~ 30 sq. ft.
    - PECO charges from my March bill are...
    ... $.0682 x 600kWh and
    ... $.0379 x 2493kWh which equals ~$135 and totals ~$260 after Customer, Transistion and Distribution Charges.

    I think I got everything this time. And if it matters. I like to be comfy in my house. Meaning when it's hot out...it's very cool in my home and vice versa.

    Thanks again, and I can't tell you all how much I appreciate the help!!!

    Your equivalent TOTAL rate is nearly $0.10/kwHr (simplification, $260/3093 kW-Hr, $0.0841 actual current)

    TRANE XL14I and 16I models

    Second Floor First Floor Case 1 - TWO XL16i
    6024 1058 6036 1560 2618 Cool
    xxx 5063 xx 7834 12897 Heat
    xxx xxx xxx xxx 15515 Total

    Case 2 - TWO XL14i
    4024 1218 4030 1682 2900 Cool
    xx 5498 xxx 7682 13180 Heat
    xx xxx xxx xx 16080 Total

    Case 3- Single XL14i (or XL15)
    4042 xxx xxx xx 2912 Cool
    xx xxx xxx xx 12480 Heat
    xx xxx xxx xx 15392 Total

    Case 4- Single XL16i - 3 Ton
    ______________________________________ 2,332 Cool
    ______________________________________12,450 Heat __________________________________ ___14,782 Total

    In other words, whatever the system configuration, your electric usage is ~15,500 kW-Hr for heating & cooling based on
    stated house characteristics,
    Manual J 8th edition building load,
    equipment slections noted,
    PA weather,
    & energy analysis.

    Heating & Cooling Annual bill is
    estmated as $1,550 based on current rates.


    With objectivity, I conclude
    XL14i 3.5 ton is the best Life Cycle cost.


    Topshelf,
    Send me an e-mail if you wish to
    see more of the analysis detials.
