For a 2 ton system with a 17 foot line run the lines should be what size? Just in material cost, how much extra is the foil faced flex duct per foot? The QC guy is coming in the morning. Should be an interesting meeting.

They should be the same size as the service valves. It should also only have added a very small amount of freon to get you to operating proper operating charge. the charge is .6 oz of freon per foot of 3/8 liquid line set. I am not sure if 410-A is the same or not don't see why it would be different but it could be. Not sure about pricing on the duct work I would imagine going to home depot online or something equivalent you should be able to get idea per foot yourself. Give him a chance and be calm and collective in your thought and allow him to make full decisions before questioning anything. Being nice and polite gets you further than flipping out and threatening lawsuit....not that you would do that just saying.

compressor volumes....more power to push the same thing....pros chime in thats my answer...Also it will slow the refrigerant charge speed down trying to cram all the refrigerant from the big line into the smaller service valve line..cant see your pics now for some reason so this is just an assumption which I hate to do.

I have a feeling they are not going to volunteer to redo the line set. With all of the problems that have bee pointed out I think I am going to strongly request (with different techs) that they do so.

man as anal retentive as you are go get you some oxygen acetylene and redo the lines yourself after they remove the refrigerant lol...joking...I have the same problem as you do but only with letting others work on my car...I hate it can't stand it....even if it works right I still find the smallest thing that could possibly go wrong or that they didn't do to my liking and I marinate on it. Honestly by now the damage is probably done that will be as long as you can get them to remove the filter dryers and install new ones.

Yeah, why should the OP give a crap about whether or not his hard earned money was well spent? This is yet another idiotic comment from what I believe to be the norm. Although you deal with this stuff everyday, most homeowners only deal with it every 10 -15 years. Why don't you understand that this is a big deal? I suppose your perfect customer is the one that takes what you give 'em in the arse and then thanks you for it as your walking out the door.

An oversized suction line may cause oil return issues due to reduced velocity of the returning suction gas...it's not enough to continually scrub off the oil film that will tend to collect on the suction line tube walls. The length of the lineset that is oversized has a factor over whether or how much this problem might occur. If it becomes a problem it could leave the compressor a bit short for oil, and that's never good. Returning velocity and quantity also helps cool compressor motor windings. Less for this reason also not good.

And that is why we go by the mfg. spec. sheet that way if we have "any" issues with the installation we can call the RUUD rep. and let him figure it out without any embarrassment if we do it by the book.

New user Im really not one that likes picking on others work and I would not even say this ..... but I just had to chime in to make a point to a lot of people looking on.


SO is any Trane installer going to come in here and try to say ........ hummm that must have been put in by a GOODMAN installer.

It just points out that no matter what brand you get, as most say ....... its only as good as the install.


OK I WILL SHUT UP FOR NOW buttt Im not a believer of this coming to the site. We are now in for homeowners coming in here and posting every situation and wanting us to pick it apart.

Heck if they want to get to a point the homeowners might even start blackmailing shops by threatening to put their work in here with picture of their truck showing the sign to show who had done it, if you dont change everything to the way they want it wether it was in the price or not.

Oh and I know a few are in here saying ......... show them all of my work, i do not do anything wrong. You never know , they may just put in something that is crappy by someone else. Once they put it in , its not like you could truly prove to anyone wether it was you or not.

Seems like we are walking a narrow path right here.

Have you tried to contact their salesmen to express your concerns over this?

They have been around for quite awhile & I feel certain they would do everything within their abilities to address your installation.

My boss fired this company a few years ago. What does that tell you?

And what would anyone get out of that?

well......... you could go in as a home owner complaining. Show your competitions work ........even if its not really your competitions work. Tell your customers to look at this site.. There ya go .......... perfect sales tool to trash your competition.

Altho I was getting at a homeowner using anything they can to get things redone wether it was dont right or not. Im not saying that is the case here , but a homeowner could use the site that way if he wanted ...... a bargaining chip.



Im not saying anyone is doing it but we may be headed that way.

Just looked in the manual and it is supposed to be 3/4" for the gas line and 5/16" for the liquid line. Went outside and the gas line is indeed 3/4" but the liquid line is 3/8, not 5/16.

What are the results

:rolleyes: I think this is the results of new technicians with out supervision. They may or may not work for the company. They could possibly be subs. Just the solid crimp in the electrical and the UN sleeved copper rubbing a dissimilar tells me that they are moving to fast and are trying to get in and get out. You could ask the same sales person to come back and look things over and see what he has to say. This could be a learning experience for them and you should get your equipment functioning properly.

QC guy just left. Said they will address all of the issues I had listed for them. They are trying to blow off anything to do with the line set. They said they can't get 5/16" and don't know why Trane is still putting that in their install manual. Said nothing will be in the lines since the the filters remove everything. They say they will caulk the collars and vents.

He is sending out their top technician for the wiring, DIP Switches, thermostat, etc and a seperate crew to work on the vents/air leaks.

Unfortunately, this is a good installation compared to what I see on a regular basis from most companies. The problem is most people are not inclined to call the BBB or chamber of commerce, etc., they just deal with the company in question, and it never gets true reporting. That why a company (we do) should have a profile book you can look at showing testimonials, training cert., and actual work done by the company with the installers in the pics so you can compare the before and after and reasonably assume what yours should turn out like. Then, if you have specific problems it is easy to show that your work is not the norm for the company. But unless the above happens, you just don't know.
Everyone has addressed the technical aspects of the installation already, and I agree with the general sentiments. Always triple vacuuming is a little much though. If your micron gauge holds at 500 when you break the first time then you are fine. If it climbs towards 1000 or a little more, then no leaks, but moisture in the lines. Then do a nitrogen break. (most important with puron, r-410, since moisture can break down the molecular structure of the gas and cause major problems)
Good luck with the company, sounds like you will need it.
