    i'm sorry ..apparently you are new to the internet. it is extremely rude to interrupt somebody else's thread with your own questions. kind of like interupting somebody else's conversation. don't worry you suck at the computer now but maybe in time..you can do better.



    low bid? sorry you're are an idiot. do you do the same when looking for a medical procedure? low bid contractor's don't last very long..then you can wipe your a$$ with their guarantee.

    with a name like lowcash...maybe you give financial advice too.

    fwiw....i typed this very slowly for you..hope it helped.

    o. ha. he. you are very funny, while informative, and at the same time helpful. this will be my last post on your "so very important personal thread". also i will not look again to read your stuck up childish posts after this one. i personally had no question of my own, but my main point was that you should not have been so rude to the lady that has obviously just started this form and was looking for advice. you so quickly ridicule mine but have no confidence to give her your own. therefore you are useless, and are a sorry individual. goodbye

    Then tell me if this equipment configuation sounds right for my size home. I have been doing research and that is how I found this Forum. From that research this looks like a good/balanced system. I asked for the extra air filtration which this furnace model features as an option and it's built-in. Carrier contractor said I didn't have room in my closet for their air purifier.
    you could move the purifier, but it would cost you more in duct work... and maybe efficiency

    With out knowing the other particulars about your house, using the Sq. ft method using 600 it comes out to be 2.75 tons of cooling needed to cool the house. you mentioned a 48,000 btu A/C I'd say it is over kill unless you do it right by having a contractor come and run a manual J on your house. That way you will know what is needed and you won't have to pay and suffer with oversized equipment. The 80,000 btu furnace is most likely too big also. If your gonna push 48,000 btu's (1600 cfm) through 8 registers I hope that they are some big ass registers and that you have a whole lot of returns. Better get some ear muffs !

    what about duct size?

    one guy came over and i'm sure he knew his stuff- he wanted to put in some kind of super skinny ducts. now i don't understand why i would need this with the walls open and the usual stud work all around.

    how big is a duct in the wall anyway? and how big is a skinny duct and what's the difference? the price difference on my end is about 3K but i dont' understand why that even is necessary?

    does anyone know why it's necessary? is it?

    meanwhile, i am leaning strongly on the carrier infinity as they guy that knows his stuff actually has that one in his house- so it must be good! it was also suggested by my most reasonable bid- also a man that i believe knows his stuff.

    while there's always more than one way to accomplish a goal is there a better way in this case or just a different way?

    thanks, chrystia

    A duct in the wall is 8", a skinny duct is 2", so the difference is 12", give or take a few inches. The price differnece on your end is 3K because skinny duct costs more to install than fat duct. Dont ask me why, thats just the way skinny and fat duct are.

    I know why its necessary? Yes, it is very necessary. Skinny and fat ducts are the answer, what was the question again?

    rogerk, thanks for your answer. it doesn't seem to add up correctly, however,the difference appears to be 6".

    the next question that i have is that a regular duct then, at 8 inches, seems to fit well within the wall studs. then how deep is it if it is 8 inches wide.

    it also seems that installing central air in the hot summer is not on the favorites list of too many contractors. i don't see the need to install a skinny duct if the regular one fits in fine. do you?

    It's not the contractors, it's the people working for the contractors.

    so what do we think about the carrier infinity 16.8 seer with a 13 eer? is this the

    best 4 ton model? there is one upgrade at 17.3 seer and 13.4 eer in a 4 ton model. i am told. is this correct? 2 stage, hi speed.

    do we like it? i think i like it? what about the professionals? do you like it?

    best kind of duct?

    what's the best kind of duct? flexible or rigid? the guy i'm thinking of going with wants to give me flexible all over but i think some of it should be rigid.

    opinions please!

    Thanks for the reply. Between all the convoluted posts that started up after chrystia bumped in to "share" my thread...you are the only one that has made a serious reply with regard to the equipment I mentioned. Your point of view is well taken.
