Sorry to hear that. Hope you get to feeling better soon. I've had a lingering cold here.

Cheers, Jeff

Christ I'm not dumb. And I've got *the* text book and the installation manual, all posted earlier. I've got a freon license. I've done auto air. I have an EE degree, so it's not like enthalpy is a foreign concept.

I'd pay someone else to do it if I had money to burn, but I have too many other things that I'm burning money on.

I have no practical experience with this, which is why I posted, and other than Trader and a friend or two, I've gotten no help and little more than insults.

I don't like being insulted.

I've got a couple questions about the suction line, but it is pointless to ask them here. And that is OK, because this is not the only show in town.

Now, I've gotten this far without ever having had anyone work on any of my cars (there is little in a car I haven't done), or any of my electronics, computers or a slew of other things. I'm not recommending that for anyone, but it's how I've gotten through life.

Now, I've got other work to do and I probably won't be following this thread anymore. Why should I?

Jeff

I used to get walking pneumonia about once every 5 years starting around

1985. I had it last winter and waited too long before getting antibiotics which knocked it out in a week but the weakness lasted eight. Last Friday I started coughing clear phlegm and my nose kept dripping and it was a harbinger of wicked things. The stuff turned brown late Saturday, I called the doctor''s office Monday morning and started on a course of antibiotic treatment that day. I feel like hell and am just as mad. I have a backlog of work of every description including HVAC and refrigeration. I was supposed to go clean a condensing unit in a kitchen tonight while the place was closed but was too freaking sick. That's why I'm so angry at those evil little bacteria. :-(

Man, I'll tell ya there are a myriad of little things you have to look out for when "custom" building an AC system which is what you're doing with your setup. One item that anyone who's serious about Ref & AC work needs is nitrogen. I have two Q sized cylinders that I keep in rotation and was lucky enough to find them abandoned at different sites years ago, the deposit on gas cylinders can be expensive. A great many techs who do refrigeration and HVAC work for a living are clueless about many of the things I consider necessary including the use of nitrogen. N2 or nitrogen is very important for removing contamination from the internal plumbing of refrigeration equipment and for providing an inert gas flush or environment inside copper lines that are being silver soldered to prevent oxidation. I also use it to test pressure switches, controls and pressure operated items like valves. When me and my friend GB install a system in a new home or remodel, we don't install the condensing unit until the house is to be occupied. The stub of the line set which is connected to the evaporator is flushed with N2, capped then pressurized via a soldered on Schrader valve to 100 psi. The charge will stay virtually unchanged over a wide temperature range unless there's a leak or damage by the other trades via a nail through a line. This practice also keeps bugs, dirt and moisture out of the line set. Your Goodman condensing unit is likely to have a small factory installed liquid line dryer inside the unit and if you're going to use a new high side dryer on your system, you need to remove and jump out the old dryer. There are dozens of other "little" things that you need to know about AC work that I'm too tired to list right now at this late hour. It's dark out there and I'm about to pass out again after letting the attack Chihuahua outdoors to chase the booger man and relieve herself. She's my roommate's dog but I think she likes me better. ^_^

Jeff, if you were close enough to my area, I'd be glad to show you how to do the installation because I believe you have the ability to absorb and retain the information and experience. Bright enough folks who appreciate the intricacies of some of the technology around them a few and far between in my experience. ^_^

I'm giving a whole new thought to not avoiding getting a flu shot shot every year. I still feel bad.

Ahhh.

One item that anyone who's serious about Ref & AC work

You know, I was just thinking about that. I'm not sure how good my old Robin Air pump is and I thought about purging with N2. My understanding is that you need a little R22 in there, but I'm not quite sure why the refrigerant. Seems like I should probably let in a little R22 and purge a couple times, I think that is even legal (more or less).

Clueless is not uncommon!

N2 or

Yes, it does. Little bitty thing.

and if you're going to use

Hadn't thought about that. The outdoor unit has been more or less open for a couple months. Should I do this?

I crawled in to look at the evap today and it wasn't as my friend had said. The lines were broken right at the fittings and I damaged the suction side broken line getting it out (to say I'm irritaed with myself is an understatement). I thought I might just silver solder this back in. The other thing is that this 5/8, not 3/4 like on the Goodman. My thing is that I should probably run 5/8 over and transition at the Goodman, but I don't know and this raises other questions.

I suppose I should have looked at the Goodman more before I left, but I had other things to do. I don't know where the TXV is. On a Chrysler it's bolted right on the evap, but I forgot to look here. There is an orifice in the A coil liquid fitting. How does this work?

I'm thinking of suggesting a tradeout (I write websites up to City/County size) with the guy who lent me his College Refrigeration text, not sure if I can swing it as I only know him from trading at his business.

that I'm too tired to list right now at this late

I imagine!

Just cats here, and I must say having had dogs just about forever, it is so very nice not to have to tend to their constant potty needs. It's the or else that makes people go out in all kinds of weather.

I am, of course, in Atlanta, or as my neighbor calls it "The Crime Zone". What part of Al are you in? I haven't been to Al, since my girlfriend blew a head gasket in Cheaha. Boy, was that an experience!

They have a shot to keep from getting that now. Every year My primary care tune up offers it to me. I understand that even the free clinics give it. Which means it can't be too expensive.

Next time you go to the doc, get a vaccination for pneumonia.

Also tell him you want a script for Cipro or other antibiotic that you can keep on hand for contingencies. As long as you're collecting prescriptions, get one for Vicodin or other pain reliever. You never know when you might break a toe or get a toothache in the middle of the night.

If your doctor won't cooperate with your informed and rational reasons, find another doctor.

I, for example and with a cooperating doctor, have laid in a small supply of meds that might come in handy in case of a disruption in normal services (hurricane, monkey invasion, whatever). This pill-pack includes Vicodin, two types of antibiotics (Cipro and SMZ/TMP, Valium, and a few others).
