Installing a Goodman TXV metering device. Step by Step
HTML-код
- Опубликовано: 18 окт 2022
- Hello all and welcome back to the channel! In this video I demonstrate how to install a Goodman thermal expansion valve on the outside of the evaporator coil box. This method allows easy access to the txv for adjustment or replacement later on down the road. YES a nitrogen flow was going while I was brazing the lines in. This segment was removed from a full replacement so that's why it isn't in the video. If you have any questions about this process, please feel free to ask in the comments.

Thanks! Superfast and informative response. Your channel will be the first I check for anything HVAC related
Bro i like you videos I am rookie And your videos help me a lot believe me thank you very much
That’s awesome to hear man! I really appreciate that and I’m happy they are helping people. If there is anything in particular you’d like to see on the channel let me know and I’ll do my best to create some content on that! Cheers, Dave
@@diyhvacguy thank you
I really appreciate your quick response.
Thank you
Thank you so much Joe! I really appreciate you. If you need any help in the future don’t hesitate to reach out!
Another great Video my friend. Thanks
thank you sir :)
Great video 👍
Glad you enjoyed it! Make sure and subscribe for more helpful hvac tips! Cheers
I thought TXV only go inside of the Evaporator coil when get the most Contacted of the Air running System 😊
Also is the tr6 ok for heat pump? IE does it have internal bypass for heating mode?
Shouldn't the bulb be installed before the external equalizer line?
Lookin good, been there ,Done that too.
Can someone comment on the differences in setup. ac vs heatpump. can a heatpump use either txv or piston. what else to consider.
Can you mix and match condenser and evap coils. I know you consult on that and I may do that.
Thanks dave.
In plumbing when you connect two lines u need coupler in this case at 2:11 you just slipped the connector without any coupler. So question is do we need to expand existing copper line or I can use coupler
Wait, what? Watch the video again. Its 100% threaded after brazing/soldering. EZ-PZ. Your TXV should have instructions to follow.
Great video
Hi! I have a system that's leaking right at the brass nut connecting liquid line to the txv. Is it a flare fitting?
It probably just needs to be torqued. I’ve had a few develop a leak there. I’ve since purchased an adjustable torque wrench. It should have 30ft lbs of pressure on that nut. It’s not a flare, there is a seal in there. And the seal is what seals against the two pipes.
@@diyhvacguy thank you!!
Hey I have a question, I see your lineset is running horizontal, does it matter if you install the Txv vertical ? So your txv will be up and down
I’ve always heard it should be horizontal if at all possible.
Lol I’m having that problem right now as we speak how did u install yours?
If installing a new AC which evaporator is better. The one built in txv (CAPT) or w/o and install it outside (CAPF)
Built in hands down. Much easier to install
Thanks
Did you evac the system after installing this valve and then recharge the system?
Yesir
What are the advantages and disadvantages of installing the txv on the outside of the cased coil? I was told I should put it inside...
Can adjust superheat without having to open Evaporator case. Goodman provides a insulated jacket for the txv in their txv kits
Put it on the inside if it's in a hot attic. My HVAC guy put mine on the outside. Now I'm dealing with a constant rusty pond in my drip tray in the attic. They've tried to insulate it THREE TIMES now, and the insulation just eventually gets wet and falls off. Glad the drip tray is holding up, but worried it will eventually leak onto my ceiling.
Where can I find that part where the external equalizer taps into? The suction line attachment with the port? What is it called?
It comes with the txv kit.
Thnx! Im a DIYer and I acquired a TXV from an estate sale a few years ago and low and behold soon i will be replacing an Evaporator and that txv valve matches the system but i dont have the pipe attachment. I am contemplating using a line tap but worried about leaks maybe ill solder one in instead, just need to have the Schrader removed
how about installing a dryer in front of the TXV?
Goodman condensers come with a filter dryer built into the condenser so an additional one would not be a good idea.
Do you have a to have a txv?
There is another video of the new furnace with a new ac coil that you installed but you didn’t install the txv valve , why? Not all the coils need a txv valve installed?
No, it depends on the efficiency level of the equipment the customer chooses 👍🏼 14 seer js the standard least efficient and 16 and up requires a txv
@@diyhvacguy I got it , thank you very much ,
Great helpful video! I have two Goodman CAPF3636A6DB 3-ton coils. Replacing the two 2-Ton Freus condensers bcs they are crap. Can I and my contractor add a Goodman 2-3 Ton TXV to each coil and then replace the two Freus condensers with two 2-ton Goodman condensers? This home is a rental and only 1900 square feet. Even in El Paso, TX 4 tons total should be enough and 6 tons would be overkill. I called Aspen tech support. In my house, also El Paso, the coils have factory installed TXV and the tech said it was no problem to change the 5 ton to a 4 ton condenser and the 3 ton to a 2 ton. 8 tons of cooling would be utter overkill for 2900 square feet. Had I known in 2015 what I know now, I would have never let that company install the current system. I have not had one year that something didn't go wrong with the AC...that is why the Freus cindensers have to go. No problems with any of the other components...thanks in advance. Goodman tech support will not talk to puny homeowners...only licensed professionals 😢
Would you also recommend installing a hard-start capacitor in my condenser? Based on what I read, this capacitor gives an extra jolt of electricity upon startup to push the refrigerant against higher head pressures that are present with a TXV system.
Yes you can purchase the correct size field installed txv and install them in an existing coil. Also I just uploaded a video on hardstart kits. I think they’re a great addition to any condenser new or old. If you need some help or advice, feel free to check out our membership over at Patreon.com/diyhvacguy Cheers
@The DIY HVAC Guy thank you for the superfast reply...and yes, I will subscribe to, as well as financially support your channel!. I will retrofit the condensers with hard-start capacitors and coils with TXVs at my other properties...and any future systems my contractor and I install for anyone else will have those to items as well.
Why do they always come with a steel bracket to mount the bulb? Dissimilar metals hmmmm...
The lesser noble metal corrodes. Itshould never be an issue
You didn’t braze in the TXV at all. Lucky.
I thought the txv should be close to the evaporator coil and the bulb placed vertically
No bulb is always horizontal, and as long as it’s within like a foot of the coil it will work just fine. The closer the better though
letting pressure off like that is dangerous id never do it. saw a guy cut a little to much it blew the cap off and almost took his eye out. Always just loosen the bolt
This look 10x better than mine, I want mine removed and done like this. The plastic grommet on the could is all melted from the braze job. Makes me mad.
Hey as long as it works right!? Haha thanks for the compliment :)
@The DIY HVAC Guy I have been cleaning up the install mastic all over, wires all running in front of panels etc. When I adjusted the capillary tube 20 minutes ago the capillary tube started leaking. As mentioned the tech braze job is pretty bad and he had weakened part of the capillary tube with his torch and now I have a pinhole-leak on the capillary tube. 😱
@@tuanische oh no! While it still has positive pressure you could pump that freon into the condensing unit to do the repair. Then vacuum the system and let the freon back out. If you haven’t seen my other videos on that check them out.
I have watched about 6 of your vids. (maybe more) No luck finding the recapture vid, but I did see we are in the same state when I saw your Publik coffee mug. Used to go there when I worked in SLC. Great place.
@@tuanische ruclips.net/video/sR5wIbNrs7Y/видео.html here you go. Watch this. It may help for your situation.
It looks like you mounted camera on your hat, if you don’t move your head fast, i will not get dizzy
Hated when the customer nose all on your shoulder smh 🤦🏻♂️
I know right? They were pretty cool. They did the majority of this install, and hired me to install the txv and braze the lines in.
Trade term is “helicopter.” Hovering over you.
