Replacing Reversing Valve on Goodman Heat Pump Condenser
Вставка
- Опубліковано 24 бер 2024
- Had to replace a reversing valve today but before we did that we had to solve a "rattling" issue on a blower motor for a furnace. This was my 2nd time ever replacing a reversing valve and ironically both have been Goodman 🙃

Good job man. There are a few tricks to putting on reversing valves that you learn over time. One of the tricks that I like is to cut out the old reversing valve leaving fairly long pieces of copper on the valve then unbraze those pieces and braze them onto the new valve. After that, use couplings to reattach the whole assembly. This allows you to do the difficult brazing outside the unit while being able to keep the valve cool.
Bro that's freaking genius. My boss did that with a rheem when I first got with him but I didn't have enough 3/4 Couplings on me to do that. I normally cut out compressors but after burning a hole in that pipe today I definitely will try to see if can do that trick instead. Don't wanna go through that again
@@AB_HVAC yeah, my boss that passed away recently taught me that one. He was 72 years old and had been doing hvac for over 50 years. He taught me a lot of cool tricks like that.
@@AaronPowellvox old heads know it the best. They got all the good tricks
@@AaronPowellvox I already knew about the reversing valve trick. What other trick you got up your sleeve Aaron if you don’t mind, sharing
@@TNHVACLIFE lots and lots. Been doing it for 26 years and most of the people I’ve learned from have been doing it for even longer. As far a reversing valves go though, another trick is to have a vacuum pump running if the oil in the compressor starts to boil off causing phosgene gas. Braze one joint, then cool the part with water before brazing the next one. Removing the entire condenser coil like they did does help a lot. You can also make your own couplings with pipe by using a hand grip swagging tool. It’s a very cheap tool compared to the hydraulic ones. It’s also easier than the ancient hammer swagging tool your grampa used. Removing the compressor before the reversing valve helps avoid phosgene gas as well.
Damn good job man!
Congrats. Keep going up . The. Videos and humor is appreciated 🫡
I try, thanks a lot for watching the video!
I bet that wheel is off balanced or the weight on the vain is gone, most of them do have a weight on the wheel
Check the uniweld tuning fork tip it's made for sweating reversing valves.
i love your videos your a pretty good tech
Shot screws through both of those supports that hold the fan
Good job
Haven't had to do a reversing valve yet, definitely dreading the day I do
They aren't as bad as it seems. The hard part was getting the true suction line out
Straps on all four sides as far back as you can.
I prefer to use my B tank while removing valves and compressors then using the oxy ace to braze it back in
Bend a piece of sheet metal and put it where it broke and another one on the top left.
Do you guys just do maintenance or do you also do installs?
We as a company do installs, closest I come to that is condenser swap outs. I do my best to showcase our guys work when I have to go behind them for start ups
Blower wheel is out of balance…needs to be cleaned…then it may run a bit better with less vibration…
Commented before I finished the video…sounds like your wheel is still out of balance
Good job on the rev valve if it was truly your first time
Ended up doing that and replacing the blower because I was told to. Honestly have seen worse blower motors not cause that bad of shaking so I thought it was the housing
Clean the squirrel cage FIRST,THEN ADD XTRA SCREWS.
IVE SEE THIS B4 IN RENTALS Dirty ones
May be the bearings/bushings in the motor are gone after all that vibrating.
@stevea6722 I think the blower motor could've been fine. After removing it from the furnace I'm sure the wheel was the real cause but it doesn't mean it didn't mess up the motor. I would've liked to try and see if I could've gotten away with just the wheel cleaning, if I would've thought of that in the beginning 🤦🏾♂️
Captain Hook tip for reversing valve brazing check it out
I think I've heard of it
@@AB_HVAC It’s great for brazing in general too. It’s definitely worth it.
New furnace
🤣🤣🤣
I burned my first reversing valve... BAD! 2nd time, i used wet rag, too, but i didn't undress the whole unit. I think the reversing valve is the worst repair you can do. For me, anyway. Good vid
I think Trane may have the easiest one because you really don't have to disassemble the whole system to get to it. I only took this apart because the first time my boss came to help me on one, he took the condenser apart so he could get all around the fittings. And that unit happened to be a Goodman too 😅 so I thought why not do this one the same way
@@AB_HVAC yeah definitely the way to go. Looks wayyyy easier. I chose not to because I had like 6 or 7 other calls including the valve replacement it was summer time and we were busy. Was it leaking or was it stuck?
Replace blower wheel and squirrel cage
Aren't they the same thing?
Whoz the lady with the pony tail? Sometimes the balancing weight falls off. A new wheel should fix it.
🤣🤣
Big slim to the rescue?
take the fan out and clean it
Did that lol. Was told to replace motor as well though
Easier to cut reversing valve out with snips
you flame needs to be just a bit hotter brazing goes a lot faster and easier, just keep it moving
Yeah, I told Jacob the moment I popped a hole in the true suction line it was because I didn't move the flame around the pipe I got distracted and left it concentrating the heat on one point like a dummy
I disagree. You are using a very oxidizing flame, which is very hot, which is why you are compensating for that by keeping the flame away from the copper which doesn't really get the copper heated up. So to counter that compensation, you move the oxidizing flame closer to the copper which in turn is burning a hole. Try a neutral flame with a number two tip, keep the flame a little closer and the heat will wrap around the joint, while moving it slowly, then apply the siflos when the copper just starts to heat up and turns a little red.
sorry man my bad
You're good lol
Use Stay Bright 8, instead of 15% silver
Works great, less heat
I've been told it's great but doesn't hold up over time. I don't mind doing it this way
@@AB_HVAC whoever told you that about staybright 8 is just hating. My mentor been using it forever with no issues. I only braze when I got old ass piping or its not perfectly round.
@MoonRambo702 really? I hear more people say if you're looking to get away from traditional Oxy/Acetylene setups just go straight to press and to not waste time on the staybrite 8
@@AB_HVAC not tryna spend 3k on a press and fittings tho. Depending on how much u use it, the time saved will prolly pay for itself in a season.
For property mgt jobs with a tighter budget..
stay8 and a mapp torch is clutch. cheaper and looks better, plus don’t have to lug the oxy torch.
You don’t braze with nitrogen in the line 👀😬
Not on systems with pistons I don't.
Clean the blower is the first thing to do when it shake like that, no reason for a new blower
And I didn't even think the wheel would be an issue but I for sure didn't think the blower needed to be replaced. Learn something new everyday
Replace the blower wheel. It's very out of balance
If cleaning it doesn't work
The cleaning DEFINITELY worked
2x4 with a ladder pad screwed to that floor joist and lifting up that piece of shit blower would quiet it down..... If they won't replace it
🤣🤣
Lol.
Looks like someone replaced the blower motor and capacitor and to make it easier to get everything out just cut the sheet metal with tin snips. So why are they calling you now? How about calling the Jackleg that put that blower motor in without cleaning the wheel.
They called us because they needed to get a tennant in there fast as possible 🙃 I guess everyone who kept walking it complained about the rattling
@@AB_HVAC be very careful working for rentals. They are very good at using and abusing you, expecting you out the same or next day and then taking their good old sweet time paying you. All while complaining about your prices.
@rv10flyer84 man, don't I know it 💀 3yrs doing work for property management's and that's SPOT ON the situations we deal with
@rv10flyer84 but they give us steady work and keep the doors open so I'm cant complaining too much.
Strapping the control board to a vibrating fan is not very smart guys, c’mon 🙄
Thanks for watching 😁
Reversing valves are a total bitch.
