    Frown

    Opions please!
    Just replaced compressor on 10 year old goodman 3ton condenser as well as run capacitor/contacts. Getting 300+ and only 75psi on low side. It has an old filter on the low side. Had to size down the high pressure side of compressor from 1/2 to 3/8 to connect to coils.
    Inside coil is not a match to condenser.

    System was cooling and sweating the low line prior to the replacement of the above items.

    Problem. cooling insuffient to even sweat the low line.

    I have my suspicions, but would like input.

    1. Then why was the compressor replaced.
    2. Why wasn't the old filter in the suction line removed while you had the system open.
    3. Is the new compressor the right compressor.
    4. Did you install a new llfd.
    5. Did you leave an old llfd in teh circuit.
    6. What was the SC, SH, IBD,IWB,ODB.

    Bunch of problems here:

    Just replaced compressor on 10 year old goodman 3ton condenser as well as run capacitor/contacts.

    Why? Costs alone would make this repair not feasible..(if all was done correctly)

    It has an old filter on the low side.

    Again, why did you leave it? Why was it there in the first place?

    Had to size down the high pressure side of compressor from 1/2 to 3/8 to connect to coils.

    Sounds like the wrong compressor...

    Inside coil is not a match to condenser.


    So....this there should of told you NOT to do it.

    But:
    The main reason you will not get tech advise, please read the site rules...

    IMO: You should of replaced the system.

    THe answer to the question you are asking is this give your tools away and get into another field there are alot of red flags here. The suction drier sticks out the most. Why was the compressor changed it brings question if you would leave a old suction line drier on the system after you had it open then can you honestly say you checked the compressor out correctly?

    I thought I Might get some real advice here. Instead I was badgered.

    I said I thought I knew what to do. Good thing. I sure as hell wouldn't have gotten a handle on it from the insults here.

    I have been doing a/c for over 10 years. Surprised? Just wanted to know the "kind" of tech talk here. Guess I found out, huh?

    In any case the problem was very simple. Remove the old filter and install an new one on the high pressure side. Gages read great - cools great _ i'm happy....so is my tenant.

    Just for the wise asses: I replaced the compressor because the run capacitor failed - it was 10 years old. The new one was a copeland - I like those. I didn't replace the dryer because I was out of new ones!

    Try to be more helpful. Some people know what they are doing, you know!

    The advice given here can be top notch.

    Sometimes a troll will come on through and try to stir things up, and show everyone here how little we know, since obviously no one here could possibly match the knowledge of a troll.

    Another possible option for getting good advice here... fill out your profile, register as a pro, post tech questions in the pro section. Odds are much better you would get better feedback when the guys here know you aren't trolling.

    Didn't replace the drier because you were out of new ones? Supply house? I mean I'm sure it'd work with the old one, but why risk it for a little extra cash? Why not make sure you had the supplies for the job when you left the supply house where you got the compressor. And yes, I know we all forget things sometimes....

    You replaced a compressor be cause the cap was blown?

    Hope your auto mechanic replaces your engine because your battery went dead.

    You didn't give the info required for anyone to be of real help.

    And I'm glad you don't work on my equipment, or I'd be paying for needless parts.

    Your tenats happy, thats great, you may waste your money how you want.

    You been doing it for 10 years, well from this example of work, you've been doing it costly for your customers putting on parts that aren't bad.

    Guys, you're all correct. I did replace the compressor too soon. However, I didn't mention that the cooling capacity of the system was not up to par.I've had complaints over the past couple of years. I couldn't get any more cooling from that system. I felt that a new compressor might do the trick. I was right.....after I took out the old dryer. I was surprised that that could be the only cause for the lousy pressures/poor cooling I saw after installing the compressor. The supply houses were closed when I realized I was out of dryers - my fault. I stock complete systems. It's very unusual that I didn't have a dryer! Too late in the day and I had to come back after the weekend. Luckly the property is very close to me.

    I wanted some feed back about the problem. I gave you enough info to "work on the possible problem".
    Why would you try to "pick me apart"? Why don't you try to help with only the problem? Don't start other problems. It ain't personal! Are you here to help?

    How many of us non- professionals have noticed when anyone that asks a innocent, but difficult question, that the so-called "big shots" (lol)can't figure out an answer for, these'big shots always come back with some kind of sarcastic reply, or in this case, they label this poster(jhayes) as being a "troll".?

    com'on you guys,you don't know it all, stop trying to be so 'high and mighty'.
    If you don't know the answer to the problem, then say so, and maybe someone who does can put their advice to use instead of calling the poster a troll or some other slandering remark.
    there are some very good "pros on this site who can give an respectable reply to difficult questions, but there are many other 'so-called' pros that cannot.

    they, (and we) know who they are.

    I think had this been posted in the pro section, the outcome would have been very different. I've seen newbies ask seemingly simple questions in the pro forums and get good answers. I've seen similar questions asked in the open forums and get slammed. Overall, I've found the technical advise to and from pros to be excellant here. I've also seen some good advice given to home owners and some slams. Sure, I would like to see a bit more tact used when dealing with a potential DIY situation, when I answer with 'I can't tell you that', I always try to politely explain why.

    The intial post did leave some obvious questions such as why the drier wasn't replaced. An answer to that would probably have prevented some of the remarks.
