    So what does he want? three, .5 ton splits? That seems silly.

    I am thinking... RUN fast as you can. He will own you.
    Can someone please explain to me -
    Why is there never enough time to do it right the first time, but plenty of time to do it twice?

    We settled on one three zone Fujitsu Halcyon set up and one dual zone Halcyon set up. that way the bed room s can be heated and cooled independantly of the rest of the house. So I think all are happy with this arrangement. But most of all I'm happy I can give him exactly what he wants and still be able to take pride in doing a clean professional install. All it took was to sit down with him calculate his energy consumption for his "independant zones", then calculated the set up I wanted to do and boom goes the dynamite. It would have saved him a whooping 10% but cost him an additional 60% upfront. Which means he wouldnt see a return for atleast 10years. I know at my house when I changed to mini splits my August bill went from 422.00$ in August of 2010 to 260.00$ in August 2011. I could prob get it lower if I added stucco over my brick but I already have foam in my walls so stucco will have to wait.

    The Quaternity systems will control the indoor RH to an actual setpoint.
    If more government is the answer, then it's a really stupid question.

    I have had more problems with lg units than I care to think about. And their tech service is useless. I have done quite a few Fuji single and multi zone s and never had a problem ever.

    His house is so super insulated does he even have enough of a heating/cooling load to justify 5 units? 5 units @ 5,000 BTU each is 25k.

First problem is that he is a Mechanical engineer, second he called me but doesn't know why he called me, and third he has a wad of cash to blow. He wants his 1200sqft house outfitted with minisplits in 3 beds the kitchen and living room. No problem right???? Wrong he doesn't want a multi zone set up using one condenser, he wants an individual inverter condenser for each room. yes that's five condensers!!!!!!!!!!!! he is swearing that it will be way more efficient this way. I'm telling him he has lost his mind all together. I'm trying to explain that running five appliances will always be more than running more. At this point he whips out a four page calculation he did. I'm not joking. And then tells me he was given my number because I'm the guy who will get done and get it done right. (oh flattery) I told him I would do it but would not grantee that he will get the results he wants. Then i told him i need a day to do some research before we sign any paper work. What's your take on this???? By the way walls have 4" foam open cell, attic has 12" closed cell, windows are all insulated and have sun shades. Also has a 6 inch fresh air duct with dehumidification and double filtration that he designed and installed him self. All electric appliances. In New Orleans.

    Mitsubishi has a great load calc program for the multi-zone systems in which you can compare calc to calc. Mechanical Engineers love this. Check out this benefit with your local Mitsiubishi distributor TM.

    Respectfully,
