A couple of issues come to mind about the TXV. The first is that we don't know for certain whether the TXV the shop installed is any good. The second is that the sensing bulb is wrapped in what looks to me like duct tape, which isn't sufficient as far as insulating properties are concerned. It's lik...

In your first post, the low-side pressure was 36 PSI, which means that your evaporator is running 40°F or a bit higher, too warm for decent cooling.

What kind of TXV does your Civic have, a block-type or one having a sensing bulb?

UPDATE #2: Quite a bit more refrigerant was added to my system today. I think at least another 6-8ozs today for a total of about 10-12oz more. At 1500 rpms (ac full blast) I was able to get the low side pressure to just about 30psi and high side to 225psi. Ambient temperature outside is 86. Center ...

First, check your Manifold Gauge Set and/or RRR machine, as well as the hoses, to verify no equipment leaks. At 86°F with a full charge and good condensing, the high side should be around 200 to 220 PSI. Since yours is an aftermarket system, chances are that the specs aren't the same as those for a ...

swampy 6x6: Note that this thread is more than one year old, so you probably won't receive a response.

I, too, think the system is somewhat low on refrigerant. Presuming that you're testing under the proper conditions, not at idle, a low-side pressure of 30 PSI correlates to an evaporator temperature of around 34°F, which is just about right. We'll wait for you to post the high-side, center vent, and...

The Archived Forum is now working on my end.

Typically, I add about 1/2-ounce to each on replacement with new components. Of course, this is guesswork unless you're starting with a completely "dry" system and adding exactly to specifications. Then, you can "oil balance" the system or add all the oil into the compressor if i...

Unless it has an oil cooler in it or an integral R/D—which looking at the photos, your universal condenser does not have—just turn it over so that it's in the correct orientation fitting-wise. Condensers that DO have an oil cooler and/or R/D would have the fittings in the correct orientation anyway,...

Have you measured the clutch gap and/or tried nudging the front of the clutch with a suitable wood tool, like a section of 2x2, to see whether it engages? The clutch gap might be too wide for the clutch coil to pull-in the driven disk, or the coil itself might be defective in some way as mentioned. ...
