I know he let it run for 20+ minutes before doing whatever he did. I'm not a tech just the homeowner, didn't ask him to tell me numbers.



Thanks for inquiring. It is inside the cabinet, yes. I thought about insulating it within to a degree, as well as the inside of the door yes. It could be coming from the copper lines, refrigerant rushing through. Yet it sounds like it's right at this valve.

If there not listed on the invoice, He never took the readings.

Time to find a different contractor.

So if I gave them to you, you'd know if they're in range and thus causing my issue or not? That can cause said issue with whistling through the TXV if those values are off?
(albeit he said they're perfect, and idk why else he'd have me run it for 20+ minutes if not to do such)

Perfect, within range, On the money, i just know.................... are not diagnostic terms.

The only way to know if the system is properly charged is:
a) Piston metering device Super Heat
b) X-Valve metering device Sub Cooling

He needs to measure the liquid line pressure and temperature and do the math. Today's digital gauges does the math for you.

Sir, I am not a technician. He did not speak to me in diagnostic terms. He likely did exactly what you're inquiring. Me, as the homeowner, he stated the system is properly charged. This is not a thread diagnosing a technician himself. --- (the fact he let it run for 20+ minutes leads me to assume he did what you're inquiring) Oh well, I do not have numbers. -- He states the system is functioning as normal. I'm here for a third opinion in a more general sense.


So again.... if those values are off they could cause the TXV valve to whistle like so? Is there anything else that could cause the sound of refrigerant rushing thru. Is this confirmed normal/expected to some?

I would certainly trust someone that's been on your home site to diagnose it, over us cyber space techs. we can only guess, and many of us can only guess. :grin2:

Yep agreed. I guess I was just venturing here to see if it's 'normal'. To hear that sound. But yep. Two techs said unit is operating as intended, yet here I'm told it shouldn't have any noise other than 'air'.

So I'm still questioning what would cause the continuous sound. What it actually is. -- and yes to see if any of y'all also hear this sound on yours.

There's so many things that "might" cause this issue, or maybe there's nothing wrong with it. I personally have heard the same sounds many times in my 40 years, with the system working perfectly.

Yep. Makes sense. On a brand new unit, my guess is it's working just fine. It's the sound of refrigerant..

I agree with this except IF the subcooling #’s were taken they get written down. Saying it’s Perfect is a cop out.

I wouldn’t trust this tech as far as I could throw him.

Unfortunately no tech is going normally to tell those numbers to a homeowner. As it means absolutely nothing to a homeowner. We wouldn't even know what he's talking about. He'll say it's working great or not. --- In terms of writing down, this was a follow up, there was no invoice. His practices have nothing to do with this thread. Maybe he's trash. Absolutely. Maybe he's not. Whatever. I'm trying to find solutions versus focusing on the techs. Please. (yes I know, we can't help you without numbers! - well sir, just assume they are exactly what they're supposed to be. for my purposes here. what else could cause this noise? I need to learn how a TXV works I suppose)


Now. If. The subcooling numbers are off. Would that cause excessive noise from the TXV? A high pitched sound of wooshing gas almost. Or maybe that's not excessive at all.

I think I'm just going to start knocking on neighbors doors and listening to their units. Not going to bump this thread anymore... will just call a third company out.

BS
They list it on the invoice to cover there own ASS!

Same as a start up and commissioning report that I guess this guy also didn’t do.

The way you keep asking the same question over and over makes me wonder who is this mystery tech.

I'm not sure what's wrong with you man. Get over the tech. You're obsessed. The fact you literally have spent every. single. reply. focusing on a random technician instead of actually answering my questions. Is mind boggling. You are of 0 help. Literally. Trash talking a random technician does nothing to help a homeowner. I do NOT have the numbers. He is likely terrible. Pure trash. He likely did everything wrong. I'll forward you his info so you can leave him a google review.

Past that here were my questions, posted again, notice how you never answered. Don't even want you to now.




If. The subcooling numbers are somehow off. Would that cause excessive noise from the TXV?
What else may cause an excessive noise from a TXV?
Is this noise heard on your unit when cooling?

Yes I'm going to get a 3rd company out. I won't post here anymore. Mr Bill you were very helpful. Deleting this thread.

I probably did, but please don't pay any attention to me, I'm just here to break the ice with a little humor. :grin2:
