How to Replace a Reversing Valve on a Heat Pump. EP75

- Опубліковано 14 жов 2024
- So we're on this unit again. The previous tech diagnosed a bad reversing valve which was causing the unit to not heat properly. I got sent out to change out the reversing valve. This is my first reversing valve replacement, I've been able to avoid it until now. Here's the process on replacing the reversing valve on my favorite heat pump. Enjoy!!!

yo!!! not sure if you could do it when recording outside but having a condenser mic with a windmuff will cut out majority of windnoise when recording videos. I know sometimes it gets annoying but just a small suggestion. All in all watching these helps alot and gives tips as a technician myself. dig ittttt
Left HVAC for a new trade 15 yrs ago.Never saw a heat pump til I went south. My first RV is soon. You made it look too easy. I'll be watching your videos, even if just for fun. Great stuff.
Use the Carrier method of reversing valve replacement. Cut it out and use couplings to install.
How does that work?
Thanks for sharing an excellent wor!!
Good video. Thank you for all of the info.
A rose bud would of made sweating the reversing valve in much easier. Highly recommend
Great video. Thanks for putting this together.
We have done a lot of reversing valves mostly large commercial though 1 1/8, 1 3/8, that was extremely painful to watch, get a pair of cable cutters from harbor freight tools and cut the 4 pipes at the body, if needed remove the condenser coil. We did two at a church last month, From the time the first pipe was cut until the last braze was less than thirty minutes. Also with the larger ones we use two torches, a guy with a turbo and a guy with oxygen acetylene doing the brazing. If your supply house has any warranty reversing valves I suspect most of them are going to be cut off with cable cutters, seeing one cut at the supply house is actually how I learned the trick.
what about the heat blanket , you think that would work better.?
Nice professional repair
Curious question? Between replacing the compressor,outdoor TXV, and the three way valve. Wouldn’t it been cheaper and better for the customer to just replace the entire condenser? Between all that labor parts had to have been less expensive to just put a new condenser? and customer get a new 5 year on the compressor plus new labor warranty.
This was discussed with the client but they opted to make the repairs. You haven’t seen the air handler. That’s another headache.
Some people either can't afford a new one or don't care to use financing.
Good job man
Thanks for sharing man
Did you double check to make sure the value is bad
Nice work
Most the time people don’t do that. It’s a good idea and makes customer very happy when they end up not needing something expensive
Nice!
That recovery bottle has a spout that goes to the bottom for the liquid you don’t have to turn those upside down I think that was counter productive
I’m aware of that. That’s why my hose was attached to the vapor side.
When charging on heat, aren’t you supposed to hook to the true suction line?
What should the thermostat setting be set on for the reversing valve? Cool or heat?
It depends on the brand. Most heat pumps are default heat which means when the reversing valve is not energized it’s in heat mode. Requiring a call for Y for heat. In cooling the reversing valve is energized setting it to cooling mode. This is requiring a call for Y and O. Other brands are default cool which is opposite of this. Rheem and Ruud are default cool. Meaning for cooling only a call for Y is required. For heat Y and B are required.
That’s why some heat pumps have a O and others have a B. O= default heat energized for cooling B= default cool energized for heat. Y= Compressor calls for compressor. Hope this helps. Thanks for watching.
Why flip the recovery tank? Can’t you just go back with the liquid port?
Very good Experience

Yeah cut the valve out next time. Makes it way way easier. Unsweat the discharge and cut the rest out with your yellow or greens.
Way to go, nice
What’s the name of that swager?Thanks
It’s a Hilmor Compact Swage Tool Kit 3/8" To 7/8”.

Thanks Bro!
I stopped watching at 13:45 when you put the torch on the pressurized container. OMFG! I have no words.
tank open to refrigeration loop, he needs to generate a larger pressure diff to get the liquid into the unit.
You should have covered the painted surface before you used the torch, by torching the paint, the customer will now have a rust issue very quickly. This is why you guys have a bad rep because too often you are not careful and cause issues as you fix others.
Kind of details that almost any customer will see after that hard work , , all customer are more worried about to get the house cooled or heating , not the surface paint....CO
Makes me sad watching this, dude cut the damn valve out, and do the work outside of the unit
Outta AC pre-2010. Asked 2 swap a 4 wy vlv. Many outside da box swaps in NC. No good? Never thought bout it til just now? PS: No N2? Never tuched a unit w/out it. Any thoughts. Appreciate it. Best wishes/Best of luck.
Next time use your recovery machine and push the refrigerant into your equipment.
I thought about that but I have never tried it. Would there be any negative effects to the system?
@@NighthawkHVAC it is the opposite of what you did to recover the refrigerant.
Now it is the cylinder that you are pulling from and your system is what you are pushing too. Nothing negative about it. So you would not need to use your torch like you did to build the pressure (just view it as you recovered your system you didn’t need to increase the pressure from it), you would just need to keep your cyclinder on the scale to read what you pushed back into your heat pump.
Nice. I’ll try that on the next one. Thanks.
@@NighthawkHVAC Just make sure you do not fill up your accumulator when you push freon in the system with your recovery machine unless you are just going to weigh it in and not look at your pressures. I could not tell if your bypass port was before or after the accumulator. We like to push the freon in the liquid line to prevent this. Nice work.
R410 should be charged in Liquid state. Recovery machine does vapour
