    IMO after the sound problem is addressed, I'd be most concerned with the serviceability of access to the blower, the condensate trap and a proper disconnect at the outdoor unit. Ask him how he is going to change that blower motor out if and when it ever goes bad.

    He'll be out of business before the blower goes bad.

    Twilli, you are too funny .

    Worrywart, I feel for you, I've been following this thread since you started it. As another "lady", I know how much of a fish out of water you can feel. Your doing good, though. It's not your fault that this guy's a hack. But I do think that you're probably going to have someone more competent come in and clean up their work. He just doesn't sound very capable.

    Get this, when I said I didn't like the look of those lines he said, "Awwwwh, it ain't so bad.." and to demonstrate, he slide the blower cover over to get in there and reduce blower speed. Then, he sort of grabbed the big insulated return line and bent it out of the way! I yelled, "Stop!"

    Yeah, I know, that's when I should have yelled, "Get out of my house!!!!!!"

    Thanks for the encouragement, MGM2! Yeah, my intimidation levels are decreasing daily, and we have pretty much figured that we are going to have to go elsewhere eventually. Half of it is clearly incompetence, half is trying to cut corners because he just doesn't care.

    I was hoping this would get better, but it doesn't sound like it.

    guess i was wrong thinking this guy had some class and would step up and make it right

    now he is admitting he oversized the uint and wont sugest how to make it right either.


    the trap should be were that white pvc pipe comes out the bottom of the unit dropping down into the pump

    should be right there before the pipes goes to the pump

    with out the trap the return can hold the water in the drain pan till the blower turns off and then gushes out. During long run times the pan can overflo

    the trap blocks this negative pressure and alows the pan to drain properly when the blower is running and no water builds up in the drain pan

    now i dont want to sound to rough but here is the deal

    you paid good money to have a heating and ac system installed. You trusted this company to do a good job and install it properly. You also expect to be able to be comfortable this includes noise issues

    time to be less complacent and tell this smuck you want it done right and stopp jerking your chain. This is your home and comfort not his and you have every right to expect no less

    he has a responsability to you now that he has excepted you money and done the work and must comply to all of your concerns within reason

    your concerns are within reason dont back down

    We will certainly use the information provided here and do our best to get this guy to step up.

    But on the basic issue then, of a potentially oversized unit (at least oversized for ducts), is there any recourse at this point? I mean, he didn't suggest anything about removing it and I'm concerned about him not rechecking the air flow with the lower blower speed. Is there anythign he can really do to work with this unit? Remember, we live in a 1972 sq foot rancher with 790 finished below. (I know that many other considerations go into load calculations.)

    I realize that these situations upset home owners, (as very well it should, it's your hard earned money), but what is equally as obvious, is how much it really pi**es off those who hold themselves to a higher standard, (professionals), as indicated by the responses to this thread. Most of us will bend over backwards to make our customers happy and comfortable. There are, however, alot of times when we have to go in to a job and clean up after another contractor who just couldn't figure it out. It sucks when you are that customer.

    well if he determind that the size needed to be increased by 1/2 ton then he should have make the nessasary duct changes required for the increase in airflo. To say the system is oversized for the house is a very genaral statement and may be the correct size for your house but not for the duct system. More return and or larger supply ducts may be needed. To drop down is size to accomadate the ducts may not be large enough to cool or heat your house properly.

    this may be a simple as adding more return and suppy to the addition or your basement to the load of the system but not being there it is only a guessing game over the net.

    Yeah, that's why I wish you guys were closer!

    He added a return to the basement addition (for some reason there wasn't one there). It is only a 12x12 grate with a flexible duct but the sound isn't as bad down there. The return in the upstairs hall is quite large.

    There is one room (my son's) at the "end of the line" with a supply register that comes off the top of the central duct line (don't know the proper terms). It is never hot or cold enough. I had wondered about adding another duct and register to this room and to the basement (only one supply there as well). Recognizing that you may not consider yourself a duct/air balancing specialist....is this wise or helpful to overall cooling/heating needs?

    well now your getting into what should have been discussed before the job was started. This is where all your questions and problems with the old system need to be discussed. Your being here and learning is helping you but a day or so late.

    balancing isnt hard for the most part as long as you know what you have to work with and have what you need to make it work

    1= room by room load calculation. This removes all guessing
    2= duct size calulation. Lets you know the size ducts you need for the system and to each room
    both of these give you btu and cfm needed for each room and you then sized your system from there.

    Now that you have what you need for each room and the delivery system is of the proper size you can then make ajustments to push the air where you want it. there are a lot more factors that go into this but i just gave a condensed version.

    now you problems may go into more dept or not hard to say. To just add more registers to a room may help that room and may be what is needed for that room. The basement also may need more runs but keep in mind basements in most cases dont have much of a load so it is easy to over do it.

    seems this guy just put in what he thougt you needed and didnt do any calculations at all. It also seems he did not ask any or the correct questions about what you needed.

    he also didnt take into account the delivery system you have already and assumed it would be fine.

    the noise you hear may have nothing to do with airflo and be a completely differant thing altogether. He realy needs to come and spend some time to evaluate the system and all of your needs.
