Thank you for the feedback gents.

Thank you Sic! The point of this thread is to, if possible, avoid compressor removal. :) Maybe it's a crazy thought, but I won't know till I try.

I've performed a lot of searches on this forum and on the net in general. It appears that, for high temp at least, R-438A is the best no oil change choice and R-407C is the best "some oil change...

It's not to sample. It's to convert to from R-22 to R-407C.
I don't know if this is widely accepted, but it's what I'm going with: The gentleman that put this class on states that we need only a...

My thought is to cut the suction line and use an automotive style extractor.
Thoughts on that idea? Better ideas?
I think it might work well on a recip. I'm not as certain about scrolls.

I realize it's not necessarily popular, but soldering with Stay-Bright 8 will keep it a lot cooler. By the time I've finished soldering a typical joint, the liquid soap has only started to boil.

In reply to the preceding post:
Sterilizing the coil might be needed in humid climates. It’s certainly not needed here (a dry climate) in a typical residential application. Regardless of the...
Min and max settings are useful, but it's the program that I need to lockout.
I'll read up on those suggestions and others that may come. I appreciate the help.
I have a customer that wants to lockout the program, leaving occupants with only the ability to temporarily change the setting - a fairly common request I think.
I liked the Totaline thermostats...
Let me rephrase that old post by saying that it's about a fifth of a second of exposure, depending. You're not going to sterilize much of anything in a fifth of a second.

More details? An X SEER condenser with a recip and an X SEER condenser with a scroll is still X SEER. Or are we talking about some other measure?
That's not to imply I would choose recip if I...
Stating the obvious here: A referral isn't fool proof, but it's 200% better than calling Joe Schmoe out of the phone book. :)
All the links work on my 'puter dan.
Suhweet white paper brain overloading geek-heaven goodness!
This is bookmarked for when I get some down time. Well... if I get some down time. What's down time again?
Random thought: The...

I stick mostly to central Contra Costa. I've gone much farther, but those were unusual circumstances in which the homeowner agreed to deal with the limitations of a distant contractor. If you want a...
Read that over and over and over again. :)
I've had painters to my house recently. (True story.) I spent at least 30 minutes each grilling them on how exactly they're going to prep and paint the...

You want the best contractor, period. Educate yourself about HVAC till you can't stand it. Then you'll be better prepared to figure out which contractor (if any)...

Moisture removal is the product of how cold the coil surface is, how much coil surface there is and how much airflow is going through the coil. The colder the coil, the more moisture that's removed....

I imagine almost everyone is doing that. Cheating on green tax credits is the new black. In most cases it's not moral or legal of course.

Let's be real. The government isn't that generous. Of course it's a trick to say that the AC comprises only 17% of the total cost. That's not tax or legal advice. That's just obvious. :)

You mentioned the 165A and 126B in another thread. I checked on the 165A and found 4 ARI matches with a 4 ton coil: 3815885, 3815886, 3493443 and 3493437. So yes, a 4 ton coil is approved depending...

I appreciate the fixation on diffusers. It's a valid suggestion, but it isn't going to happen - period. They already replaced them once. They're not going to do it again. The diffusers they currently...

It's a reasonable suggestion bigtime. But I'm 99% certain we're going to be using a deflector like the one linked. As stated before, they spent a lot of money on high quality diffusers already...

Regarding the damper, it's not a question of volume. It's a question of direction. They want the cold air to diffuse into ambient air as much as possible before it settles to chair level, hence their...
