[ACFIXR]

Have not taken time to open txvs nor to try to make a determination on what indications might lead one to use or not use the renew.
Have had only one I think because most of my coils are piston type. The one I did have I just yanked the TXV and converted to piston. Takes a minute with the ADP coil. Later I pulled the TXV apart and saw black stuff caked on the spring. That's as far as I could strip it down. Is that TXV piston even removable? I could not get it out of the TXV body. I wanted to look inside the body.

Replace the elements and then clean the pins. All txv's should be serviceable. not this crap.

Just like magic juice extreme I'm sure. It works sometimes....

With the oil additive issue ...we have had excellent success...takes a day, but it works

We've been using the A/C renew on all our Rheem units, I would say it works on about 90% of them, seems take about 24-48 hours to take effect on those units, only a select few have I seen the A/C renew work its magic in under an hour. In total I'd say I've done about 40-50 of these units, sure beats changing the txv and filter drier.

Agree.
We had some Carrier/Bryants and the Renu seems to work great even after the 24hr gig and if It is a HP,even faster with switching back and forth.
However,
I have a Trane 20 ton RTU which Ckt #1 has a fouled orifice tube header which will not 'comply' with either renu or Supco 88 and I'm going POE or PVE on IT.
We replaced the header 2 years ago and then the Comp went out,replaced it along with proper clean up procedures and it clogged/restricted up last Summer and waiting on the Owner to decide what they want to do as it is now running on 10 ton and in a Kitchen but heck,It's a Kitchen.You can't stand the Heat,get Out,Right? LOL...

one thing I will say,,, we had txv failures left and right on rheem units last year. we proactively installed ac - renew in 1070 units (previous years installs) and the failure rate this year on them is minor. and yes rheem (copeland) ponied up and paid for them.

I had to deal with the sticking TXV a couple weeks ago. Our company had installed it 1-2 years ago, between then and now one of our old techs had gone there and added refrigerant, probably thinking it was low. When I went there, almost the entire coil case was filled with ice and the pressure and temperature readings were all over.

We had to return the next day with some of the AC renew. I had to run the system in the heating cycle twice at 20-25 minutes each time to finally free it up, thankfully it worked because it was about a 1 hour ride there and 1 hour and 45 minute ride back with traffic.

I've had no luck with the ac renew, we use tempstar, in all our subdivision homes, failing at a terrible rate1/2 years, company charging 650 to replace coil, which I am not fond of, tell customers to google the issues, ask for free replacement. also asked to be proactive, call Icp, and get free ac renew, for all units installed, so new homeowners don't have to worry.

 

[ALPHADOG3]

We are paid 75 an hour, and Icp sends new coil, not txv, Icp gives 4 hours to change the coil, our labour rate is 200, but but not losing money on the 75

Had my second one last week. Another ADP txv coil connected to a Ruud a/c. Both units I just yanked the txv and installed a fixed orifice.. Done with it. I pulled the TXV apart and that pin was frozen in place with a black almost varnish like goo.

Most of these issues can be avoided by a proper installation.Refrigerant lines have to be properly flushed and run nitrogen through lines during braising and of coarse a good vacuum.Adding the additive on install to be sure this won't happen again cost a little more but cost less than fixing these issues down the road.I had multiple issues with this until I made sure this was being done on every install and know this issue is very rare at my company.

Yes true but on this thread it's being caused by a manufacturing defect FROM the factory.

Not the case with this issue. Most of us here do flow nitro and evacuate to sub 500 microns here. This issue is not related to install practices it's the manufacture cutting corners and using the customer and contractors as Guinea pigs for their failed experiment.

 

[dblaron717]

Ruud is using AC Renew.

Probably similar stuff.

I would not expect same-day results in either case.

Aren't there some manufacturers that won't honor warranty if they find AC renew in them?

No because all of them used a copeland in some of their systems in 2014.

Carrier has been giving us Zerol Ice and paying labor...no compressor failures....there is not an OEM that really checks ( other than random) why parts fail anyway
