Well, the week past.....

No BID for a new unit..... HVAC company was a no show.

Called the HVAC I have been working with on Tuesday.... and as expected a no show the rest of the week.

So given I am insulating my attic tomorrow I went up and haphazardly torn out the part that is in question... be it right or wrong.

I totally wrenched on it thinking it came apart so I could get the piston out but that is not the case. Seems to be all one part.

I've placed a call into the local Carrier dealer in Sioux Falls to see what they can find.

So... will leave this post until spring time..... Thanks to those who have given constructive feedback.

So you're leaving the line set and coil open to atmosphere until spring. Not very bright. That part is more than likely obsolete.

Spring has arrived......

I finally got what I think is the right part. Not exactly the same but I think it should work.

It came with an .063 orifice and I think the unit call for a .059 or .060.... I'm wondering what harm if any would it be to use .063 vs. .059?

Your still trying to make this thing work?
Buy a new air handler, or at least a TXV. Course then you'll need starting components too.......

Why should the whole system be replaced when only the condenser went out? I'm sorry, but if my engine or transmission dies in my vehicle I wouldn't go buy a new vehicle.....

So here is the latest..... Orifice changed and HVAC showed today..... still high head pressure..... they have come to the conclusion that the restriction is oil in the line from the old unit.

So they are saying they can flush the lines but no guarantee. I am totally dumbfounded why if oil in the line a bad thing the person who installed the new unit didn't say at that very instance the lines needed to be flushed.... No, they just wanted to install and get out.

I as a homeowner should not have to know about orifice size, oil in lines and a year later be faced with flushing as the last ditch effort.

Clearly there are good customer centric HVAC folks and others that just really don't give a S*&T

Oil in the line will not raise the head unless one over charges-

Head pressure means NADA without knowing ....subcooling and superheat--in your case with an orifice they would charge to superheat....what were the readings they came up with

so the the line set and coil have been open to atmosphere since around
Halloween of 2014?

?

It sure was.. but both ends were plugged with rubber plug.

I could not tell you what the readings were .... the HVAC just said the line pressure was no better than before the orifice was changed out.

You need another contactor "Pressure" tells you nothing without knowing Temperature.......Plugs are great for keeping large objects out, but not moisture

How old is the indoor unit again?

 

[pecmsg]

:gah:

 

[rider77]

How old is the indoor unit again?

I think I answered my own question.
Over 20 years old, correct? Same as the age you put in post #1?

Because AC systems have to be matched to coil sizes and capabilities.....In your case you put a modern outdoor unit on an old coil that cant hack the differences.

So here is the latest..... Orifice changed and HVAC showed today..... still high head pressure..... they have come to the conclusion that the restriction is oil in the line from the old unit.

OR the new outdoor just doesn't like to be hooked to that indoor coil.....Looking at that picture, I would estimate the age at 30+ from the time period of NO SEER ratings. It is NEVER going to work well!!!!

So they are saying they can flush the lines but no guarantee. I am totally dumbfounded why if oil in the line a bad thing the person who installed the new unit didn't say at that very instance the lines needed to be flushed.... No, they just wanted to install and get out.

It's because they are trying to make something that wont work.... Typically companies that do your type of work have no skin in the game...they don't have to warranty it because you bought the condenser.

I as a homeowner should not have to know about orifice size, oil in lines and a year later be faced with flushing as the last ditch effort.

You took these problems on when you didn't just replace the system with matching components. Like the post you made about the proper indoor orifice being shipped with the unit....it won't work with your mismatched carrier airhandler, that was manufactured god knows when....

Clearly there are good customer centric HVAC folks and others that just really don't give a S*&T

Yes, some companies will install mismatched frankenstein systems to get the $$$. A good company would NOT do this work because of the potential problems later on.
