 |
|
Is it just me or has anyone else been seeing an abnormally high failure rate on TXV's lately? 4 last week and 2 already this week - Trane, Lennox and Goodman. Hell that's more than the past 7 years combined - not counting the idiots that crank on the stems like a water spigot in walk-in apps.

Yup, mostly those puny little Parker valves.

Most I've heard of were the Parker also.

 Parker sucks, hopefully they don't ruin Sporlan.
I haven't seen any yet this year, had quite a few last year though.

..most of what I see is 10 SEER fixed...all the stuff I've sold (Trane/Rheem) with TXV's have not as yet had any TXV failures (except for the one I installed in my house...original was bad at start up, second lasted less than a year)...you think sloppy install practices may be part of the problem?

 No, I think Parker's the problem.

We had a run of bad ones about 2 weeks ago. My dispatcher said, "If ya'll bring me one more bad TXV diagnosis I'm gonna shoot ya'll!" That cut down on the bad TXVs real quick! 
But ya, seems like more than usual...

| Had a Trane unit yesterday. My serviceman changed it out. Have another in a Amana. Hope this isn't a rash of valves. These are fairly new air handlers. beaner |
