    Hmm

    Hi HVAC Guru's,
    I've been reading now for a few weeks and still wondering if being more informed is better than being just another mis-informed H.O. Seems the more I read the more open issues I run into.
    Here's my scoop, think I'm pretty much decided on A Carrier MVB 96 Infinity Furnace, Comfort 10 A/C, keep existing Honeywell Elect air filter, keep existing Lennox WB2-17 Humidifier. I live in the Metro Detroit area.
    The contractor I am dealing with says single stage Thermostat is fine. After reading here, It sounds like I would be better with the Infinity Control making the decision to go to 2nd stage not the timer on the furnace.

    Questions:

    Is the infinity Control function (de-humidify, super de-humidify) functional having only the comfort 10 a/c instead of the Infinity a/c? If not, is there any other Carrier A/C besides going all the way with the Infinity 18 that will utilize the de-humidify option?

    Does the cost of the unit justify any more than a 10 seer a/c living in Michigan?

    Is my Lennox WB2-17 compatible to humidify with the furnace and Infinity Thermostat? Just a manual adjustment on the humidifier right now, no humidistat.

    Is there a less costly thermidistat that will control my furnace, humidity (if possible with this blend of equiptment), without the options I may not use on the Infinity control?

    Should I go with a full house surge protector? I just got my service panel updated and had a transfer switch added for a generator. Will I have any problems running the DC motor with the Generator (Generac 7500 watt) with/without a surge protector?

    Sorry if my questions seem a little newbish, I'm just informed enough to understand some of this, but confused enough to go back to getting just a 80%, single stage furnace, 10 seer a/c, and my existing Honeywell Thermostat.

    Thanks for any replies!

    A question from another HO while you're waiting for answers from the professionals: any reason you specify the MVB Infinity furnace? I've been told there's no discernible difference (for the HO) w/the MVP - which is what I just had installled. Just curious...

    Krxman,
    Not sure if there is any difference, I believe the MVB relaces the MVP. Having a new model number I would think there is a difference somewhere????
    I'm following your similiar post right now hoping for some info on what to do!!

    That was my thinking as well. Unfortunately, I had 3 local companies give me a bid and none of them were yet installing (or were even very familiar with) the new model. But I would have got it if I could have.

    Go with the MVB Carrier is changing to Nitride Ignitors with the B in the Model number. MVP is Carbide Ignitor. Go with the Infinity Control with a 13 Seer 38TXA??? Best system on the market.

    dugfish is right, one difference is the ignitor upgrade, another difference b/t the mvp and the mvb is the door doesnt have any louvers in it and it is insulated, making the unit even quieter.

    You don't 'push' for it. You don't get the MVB from the distributor until the MVP inventory has been used. It's called a rolling change. Your MVP will work just fine.

    Lot's of less expensive units would work "just fine." I paid the big bucks for QUIET. If the MVB is quieter, as Toddb83 indicates, then that's the one I should have got. Since it's been out since July, I'm guessing if I told my installer I was gonna go w/a company that could provide an MVB, he would have found one for me. Or I could have called around till I found somebody who had one.

    Oh well. That's the way the cookie crumbles.

    Started production in October. So, it just started hitting warehouses in the past couple of weeks. We just started putting them out the door last week to dealers. So, the MVP is the one that you should have received because that was the available to the dealers in your market.

    Do you guys know about my original questions? If the 38TXA (performance 13) doesn't help me any over the 38TKB (comfort 10)with humidity using the Infinity Control, I'd would be better off with a 10 seer here in Michigan wouldn't I?

    Oops.Reread your post. Kept seeing Lennox and thought you were wanting to put the control on a Lennox furnace.
    Humidity is controlled by the variable speed blower slowingdown to reduce humidity.
