Replaced AC because of Freon Leak, New AC same problem

[rustymetal]

So here is the story, around a year ago my central air for my 3ed floor condo stopped giving cold air. We called for a local repair man.

He said the AC was really just too old, he could put freon in it but it would leak out again, and that the only real fix is to get a new system. It was old and was from when the building was built around 89.

So we get a new system, totaling around $XXXXXXXXXXXXfor equipment,install, warranty, service plan, etc.

3 months after, same problem no cool air. Service guy says freon was low and he fix it.

8 months later, same problem, no cool air, freon problem. Although this guy wrote "PMA" on the service sticker on the AC instead of 'No cool'

And now here we are, 6 months from the last service on Dec 07. With the same problem. I called for service appointment, have to wait a few days so there is no one to ***** out yet.
----------------

That's the story can someone tell me wtf is going on? Why did i spend $XXX to fix a freon problem that I'm still having?

Thanks for reading, if this is wrong forum/website sorry just a over heated Floridian here looking to vent on some forums and maybe read good information.

did they replace the line set?

As above, Did they replace the line set.
Do they even look for the leak to repair it.

Call and tell them you either want the leak fixed. Or your money back so you can get a system that doesn't leak.

And edit out your prices, its against the rules.
Who knows, a "mod" could see it and edit it out. LOL

Ps: They did change both the indoor and outdoor unit right.

got distracted. phone rang.

pesky customers.

[rustymetal]

I know they replaced the in-apartment unit that sits above my water heater.
I also know they replaces the big unit outside that is on the ground.

I'm not sure what a line set is. I'm guessing it has something to do with connecting the two units? I'm not really sure, but I didn't see them doing anything like that. Not that I would really know what it looks like

[beenthere]

The line set is the copper lines that connects the 2 units.

seems pretty appearant that a pressure test was not done after brazing new system.

So now the more important questions.

On top of....did they do leak search?
Is the system sized properly?
Is the fan speed correct?
Is the ductwork sized properly?
Are your filters clean?
Are your coils clean?
Was superheat and subcooling measurements taken?

The list goes on. There is a number of measurements that must be taken to see the full picture of what might be going on.

Sounds like you hired a sub-par performing contractor. I would call them and explain in very easy terms that if your system is not up and running CORRECTLY by Friday afternoon that you want the enitre system removed and want a full refund. That at least gives them 48 hours to diagnose, and fix the real problem. Not just put another band aid on it and gimp it along until your warranty runs out.

That may get their attention.


Just curious....could you take some pics and post em. We like to see and critique others work

well there would have to have been 3 stories worth of copper, and I know I did not see them doing that. SO I'm going to say they did not. Are they suppose to? is that part of a regular installation?

Its not required at all times. It needed to be checked for proper sizing and also that there aren't any LEAKS!!!!!

[beenthere]

No, its not done on every change out.

[jrbenny]

Guess we found the likely leak location.

3 stories.......I bet its between story 2 and 3.

Sounds like new lineset down the outside of the building time!
