Replacing restricted TXV on a Carrier heat pump.

This morning we are we are back on this one and we're going to right now we're going to pump it down and we're getting ready to do a TXV on it. Now I'm going to per her suggestion I'm going to pull this open and take a look at that piston right there and blow everything out. It was really loose. You smell smoke. All right this is my first use of the 552i as you can see i'm pulling down pretty quick i was actually able to read this from inside i know it's not very far away about 10 15 feet but um i was able to monitor this from inside and while i'm doing my work all right i got it down below 400 microns i still think i need to change the oil in my vacuum pump because normally it goes a good bit quicker than that that took about 10 15 minutes um with fresh hold i don't i don't take that like five minutes just pulling on an evaporator but i'm fixing the valve at all and um watch it all right that's with it valved off that's excellent see if i need freon let's check sub cooling yeah one degrees out here Watch it just a second kind of information you can get after using these probes is it's just phenomenal The pressure, sub-cooling, temperature, humidity, wet bulb, it's just no mess. Alright, in the end, the pressures, sub-cooling, all came out just fine. They're right where they're supposed to be. So, replacing that TXV was the right thing to do. And by the way, the 552i is nice. It's a nice addition to this set.
