    Cool Ahhhhh!

    Wow,

    Yesterday I had my 23 year old Rheem SEER 10 replaced with a new Trane XR15 4ton Condenser unit and matching GAM....... air handler (matched certified system SEER of 16.25) The old Rheem just was not able to keep up on the hot days, and my Summer electric bills were over $800 per 2 month billing period. I certainly did not do the replacement to save money, as I doubt the new system will last as long as the old Rheem, but, man, does this thing cool the house down, and dehumidify it well. They also installed an Aprilaire MERV13 air cleaner.

    The manual J they did showed another 1/2 ton was appropriate for my house than the 3 1/2 ton unit I had before.
    And the install qualifies for a power company rebate of 700 bucks.

    Anyway, I imagine my electric bills will be reduced by one third in the Summer; we'll see.

    The attic temps yesterday were 145 degrees on the sheathing and the air temp up there was about 130 degrees. Brutal on the installing crew untill they had the system running and provided themselves with some cool air up there while they connected up the rooms.

    I was up there every so often for maybe 10 minutes or less at a time, and I don't know how they do it, I really don't. I gave them a nice tip for their hard work.

    Oh yeah, AHHHHHHHHHH again!

    Wow! What are your electric rates? My bill includes water and sewer and the electric is now pushing $0.15/kwh but I barely broke $500 for a two month rate for the total a few years back, even with my old SEER 10 system in a hotter climate. The new unit I have now is looking good though because it is knocking electrical down by a 1/3 and is more comfortable as well. Global warming will make it pay out rapidly since the old unit was finished anyway, and the upgrade was only negligibly more than the cheapest option (hmmm, it is probably already paid for as of last month.)

    Hit 105 today (and I ran my 5K route in it...at a recent personal best time). Tomorrow the prediction is up to 110 F--time to do some swimming instead. Local weatherman who usually nails the trends and long range forecasts suspects we will break the local all time record of 113 F in the next week.

    I've been meaning to do this for a long time, so I will scan in a copy of my electric bill and you can see the rates, but it will not be the summer bill. I need to give myself a time slot to do this, but I will as soon as I can. New unit still running SWEET after 2 days. It was only 93 here yesterday, but the new system....... no problem at all.

    Finally got a chance to do this. This is April and May bill for this year. Including the taxes and other BS charges, I pay over 19 cents a KWH for 1897 KWH. total bill was $358.75


    I scanned the file as a pdf but it is too big at 480K to upload here. I'll see if I can somehow resize it

    Even if this unit uses only half the power of my old one, it'll take me a real long time to get my return on investment on this one, if ever, before the 10 year parts and labor warranty are over.
    Insane total prices of installed equipment here on Long Island, NY by a reputable dealer. It cost me 3X as much as I paid for my brand new GTO in 1966, but comfort is king.

    Those rates are higher than mine! Even just using the per KWH rates and sales tax yours are $16.6/kwh minimum.

    I don't know about your unit, but my old one was shot (compressor was pulling too many amps on start which was one of the reasons I knew I had to replace it...seized up on the installers when it was cycled to clear unit during replacement....and the old furnace had cut out a few times in previous days so it needed some parts replacement as well.) I got every last day out of the old compressor, so it isn't like I paid any extra to replace it. The only ROI consideration is what it would have cost for the cheapest possible unit...and with rebates for the high end gear the difference was only hundreds rather than thousands.

    Like you say, comfort is king, and that is why I chose dual stage units. The provide more even temp control at low cooling/fire rates most of the time.
