Barbar, I can't reach the compressor to feel the temp, and it's under a blanket of some sort as well.

You other guys are describing exactly what I have feared all along but have not mentioned...

Timebuilder, the TXV was swapped BEFORE I removed the water from the chase. So the water in the chase had no relationship to the start-up noises surfacing immediately after the TXV swap. A few...

Real professional reply. You should go apply with the company who installed my system.

Seriously though, worrying has nothing to do with it, the friggin' thing is waking me all night long. ...

When the system was initially installed it was making a hammering noise in the liquid line right at the AHU right when a heat cycle shut off. The installer could not figure what the cause was and...

Shophound, points taken. All I can share about checking the charge was that they did measure line temps and pressures and cross-referenced that with the chart. I saw them do that much. And Delta...

I agree entirely because the system was not making these noises for the first few months until they did an evap TXV swap (that turned out to be unecessary as another noise problem at shut down was...

Thanks Shophound, it gets darn warm here in FL Summers and even yet I still get the ratcheting sound during cooling mode. The thing I've noticed that does effect things though is how long between...

I have sounds but apparently there's no way to post MP3 files on the forum.

Can someone also clarify if a cc heater is applicable to refrigerant migration in both heating AND cooling mode? ...

My old recip compressor had a crankcase heater?? Really?

I was told this cc heater would consume 80-100 watts. That's 45KWH per month based on my system running an average of 1/3 the time over...

Thanks guys for the replies so far.

Stamas the rep verified the way I re-engineered the rain drainage situation is good, he was quite impressed actually. The chase is clear, no more water (I been...

One other thing...it is totally unclear to my why I am allegedly having migration issues. The recip/piston system previously installed never exhibited any such issues and a recip is WAY more...

1) Does this solenoid valve work for both cooling and heating mode? I get the ratcheting noise in both, although granted it seems to be longer/louder in heating mode.

2) What happens if the...

Hi,

I have a relatively new residential split heat pump (410a/Copleand scroll) system that I've had startup noise issues with since installation. A type of ratcheting/grinding sound that varied...

Well, we aren't supposed to talk price, so I'll try to draw a comparison in another way... I did look into the SantaFe and it is obviously a far superior unit to the Frigidaire 70 pint I bought. ...

Oh, I should probably include some of the math since that was the whole point of this thread in the first place...

I was able to find a calculation online that described how most big-box...

Update:

So I bought a 70 pint Frigidaire dehumidifier. I like it a lot, works great. It has to run a bit longer than I originally calculated, but that's because of the infiltration factor I...

Thanks for adding the link to show how to change the file extensions.

Any idea why the forum doesn't allow audio or video file types to be uploaded? Is that a limitation of the forum...

A lot of guys on the forum requested recordings of the sounds, so I just provided those. That's where we are at. Stop trying to insinuate alterior motives, there are none beyond figuring out what...

Agreed, but using that logic, then after listening to new systems, older system, R410a systems, R22 systems, larger systems, smaller systems, cheaper systems and more expensive systems, if my system...

Apparently no pro forum members in my area, already checked into that.

Yes, Carrier Comfort Series.

I've listened to literally dozens of systems the last six months.... Trane, Lennox, Ruud,...

I should have clariied: You need to right-click on the files and then "Save Target As", then rename the extension from .DOC to .MP3.

You're not the first person to mention the fan/hub as a...

Ok Guys, FINALLY I have the sounds to share.

Due to limitations of the site's upload engine, you will have to rename the files to an .MP3 extension to listen to them. (Sorry)

I went through...

Unfortunately, no. Not yet.

Thanks for that, yeah I was considering 30 second delay. But if that AHU coil goes cold as quick as the liquid line leading to it then I don't want any delay at all. While I could foresee the warm...

I have the stat set for no blower delay after heat mode cycle. I can easily set this to 30 seconds just as I did for the cooling cycle, but obviously that wouldn't be very smart if the AHU coil goes...
