Thanyou gues all

[@dedamarsovac]

I searched over the internet just to see if the "powered" mode is cooling or heating, or it can be any. And to see if the valve is bistable. This thing, especially at 4:57, resolved the conundrum for me. Many thanks!

[@JuanTodoli]

Excellent inside "mini-valve" visualization 👍

[@shawnfleming4511]

Excellent! You have help me to overcome my anxiety towards heat pumps.

[@acservicetechchannel]

That is really awesome to hear!

[@ericlambousy2417]

Thank you for producing this video. Thank you for the book. I will have read it several times soon.

[@RayRay-nb7tn]

Explained perfectly of how they work and how they are piped in the system. It's heating season in the south so all you service tech good luck. Craig well great job again love the teaching keep up the great work.

[@acservicetechchannel]

Thank you very much Ray Ray!

[@RayRay-nb7tn]

You are very welcome Craig.

[@sandraledger2612]

My Heat Pump unit has the RVS solenoid on all the time. Even when unit is not calling for heat or cool. Only discovered this when the unit was off for a day and checking the solenoid was hot to touch.

[@denisbonilla7657]

One of the best channels around by far 👌 I wish I work for this guy so I can learn all of that good knowledge . Thanks for another good video

[@acservicetechchannel]

I appreciate that!

[@SombraLocs]

Always making the best educational videos!

Sir you are great teacher. 👏👏👏🙏🙏🙏

[@acservicetechchannel]

So nice of you

[@carlos-kx4sn]

One of the best videos I've seen Very clear details and explanation.

[@hugogarcia7574]

Brought the spanish version of your book. Thanks it has been helping me a lot.

[@hugogarcia7574]

The videos help me too

[@acservicetechchannel]

Thank you very much and that's great to hear!

[@The-H-inADHD]

Great video and thank you! It makes things so much easier when you understand in more depth how something operates. I am working on a unit now that has a heating element and the blower fan running while in cooling mode but something went wrong with the pressures too so I'm not sure if something is also going on with the reversing valve too. But not sure.

[@greg1807]

Would you consider a reversing valve replacement video? How do you flow nitrogen though all ports while brazing? Isnt one port closed during installation preventing nitrogen flow? Thank you so much for your massive video collection an incredibly awesome book!

[@brahimabdelsadek9534]

Thanks for sharing.love learning from you.cheers from Algeria.

[@acservicetechchannel]

Thanks for watching!

[@MJ-iy4fb]

[@Synergy-95]

Great video as always I have both of your books and they are well worth it!

[@acservicetechchannel]

Thanks a lot Ryan! Great to hear!

[@AnimateInstinct]

I absolutely love this! Great job man 👍 keep up that amazing work brotha !

[@acservicetechchannel]

Thanks a ton!

[@rmeken]

Just in time for heating season

[@hiseminencetheholymacdiarmada]

Lol, not if you live in Savannah GA... 78F at 5am

[@acservicetechchannel]

Absolutely, regardless where you live, you will run into a heat pump eventually so its important to know how it operates, thanks!

[@hiseminencetheholymacdiarmada]

Yes. Amazingly we do find gas furnaces here in Savannah. Personally I don’t see a need for anything other than a heat pump, but that’s just me. Keep the great videos coming!

[@joetech5787]

Good video, thanks Craig.

[@acservicetechchannel]

Thanks a lot and thanks for your support!

[@mikelevesque3086]

Great job as always. Can you do a repair video on properly flowing nitrogen through reversing valve when removing and replacing a reversing valve??thanks so much!!

[@mikeclark1756]

Great Job

[@miguelrasmijn4491]

thanks craig for sharing hello from Aruba

[@acservicetechchannel]

My pleasure

[@MarianCobirlie]

This is the best video thank you !

[@angelcalderon9714]

You are THE BEST.

[@Froggability]

If you lift the energized coil off for testing purposes, the coil will cook / melt-down due to lack of inductive reactance? Learned that the hard way..

[@acservicetechchannel]

Yeah they will burn up! thanks!

[@FranciscoAz]

Should the reversing valve de-energize after the cooling cycle has been satisfied by the thermostat, or does it stay energized while the thermostat is in the cooling position?

[@mtbbiker6401]

Mine does not de-energize. Whether the reversing valve is energized in Cool or Heat depends on the brand. I can't remember how my Trane works but I think it's "O" which means energized when call for cooling. I don't hear the reverse valve switch unless I turn the thermostat to OFF or Heat so I assume it stays energized in COOL even when the cooling cycle has been satisfied. If you have an automatic thermostat, not sure how that manages the reversing valve.

[@mtbbiker6401]

I can confirm my Trane has the Reversing Valve energized during cooling. When the cooling cycle is satisfied, the reversing valve stays energized. I tested it with voltmeter. This means the reversing valve is not switching during normal cooling operation only when a call for heat for possibly when I turn the thermostat off completely.

[@g.martinez2871]

Great video thanks!

[@acservicetechchannel]

Glad you enjoyed it!

[@ngekabar]

Thanks

[@acservicetechchannel]

No problem

Well explained Sir. Thanks.

[@acservicetechchannel]

Thank you Bronchee Mims!

[@publicmail2]

Have an O valve (energized for AC), LUX product bought by Johnson Controls (just ruined company with it's new app) caused heat pumps with O valves in August to go into heat pump mode while in AC thermostat mode, with no limit due to firmware downgrade. I've heard of deaths caused by AC in winter, but not from heat in summer as you would likely wake up while sleeping.

[@acservicetechchannel]

That is a nightmare, too intelligent for its own good

[@sprockkets]

Didn't Johnson Controls buy out Lux many, many years ago? I wouldn't diss that company, because in the past they've made great stuff under the York brand.

[@potentialhvac6074]

So you'd have to change the whole reversing valve in order to switch the system from energizing the valve in cooling to make it energize In heat?

[@JDPeters538]

I have a 1 year old unit that has a leaking reversing valve and is under warranty for the part but the AC tech is asking $1700 labor to replace it. Does that sound fair? How often do these leak from the factory this early?

[@darrenvosper634]

I have a couple of all in one ac units from cell tower coolers I use in my shop. Can I get this installed to use as heater ?

[@randomdude5968]

Great video , what would cause to have leak from the discharge part on the top right in the brass and copper joint ? Thank you

[@TheKadoxman]

another nice one thanks man

[@eretza666]

can reversing get stuck and send high pressure on both lines(high and low ) on heating mode? both pressures rise equally on my gauge on heating mode, but on cooling mode works just fine

[@falsdistractiongames9772]

if i buy the ebook do i get it over email or how and how long will it take before i get it after the purchase

[@9to5techs]

is goodman heat pump GSZB404210A good for 2014 mobile home? in amarillo texas , r19 walls, r25 roof, r 30 floor, singal pan widows, 1216 sqft home. not air tight it has leaks. temps below 20 is like 8 days during heating seanson. i set termostat to 74 f and am using electric furnace 10 kwh for 108 hours a month. my electric rate is 0.097 kwh. the highest bill to have was 250 but that is from whole home usage. the goodman heat pump says it uses 2.9 kwh at 10 f with a COP of 2.08 and a 2.7 kwh with COP of 1.34 at -5 f. the price for the 5 ton a-coil and 3.5 heat pump is $4,876. i can get 30% off that price on rebate then it whould be $3,413.235 also, why whould tech go with mortex 5 ton a-coil and 3.5 heat pump. thanks for help.

[@UlisesPalacios]

Pretty cool 😎

[@acservicetechchannel]

Thanks Ulises!

[@wasimedoo7994]

That is a very technical valve it's two in one look like it's hard to work with

[@8joh58]

how r u! I got questions I do get it hot gas come from discharge through capillary to shift reversing valve but where is suction line gas come from? Because I see the flow in video suction gas is not come from common suction line, low gas flow back to common suction! Where low gas come from? It’s doesn’t look like to from common suction? Thanks

[@Cut3Sku11]

why not have the electric mini value control the reversing value through a solenoid? why do we need to make the main large reversing value be controlled by refrigerant pressure instead of electrical signal directly?

[@jakesales7321]

Do you sell your book using the metric measurement at all?

[@acservicetechchannel]

Jake, not at this point but I certainly would like to in the future, thanks!

[@9to5techs]

why do they go bad/leak alot

[@Mentorcase]

Is the default for those change over valves to cool in the event of a damaged solenoid?

[@acservicetechchannel]

The nonpowered position on most is in heating modes but some brands such as Ruud Rheem, the nonpowered position is in cooling mode, thanks!

[@fernandorosillo9715]

Do you have the book in electronic format?

[@acservicetechchannel]

Yes we do at our website at www.acservicetech.com/store at Google play and on the Apple Book store, thanks and the full outline and sample pages are at www.acservicetech.com/ac-book thanks

[@fernandorosillo9715]

@@acservicetechchannel thanks a lot. I'm gonna get it.

[@felixe.cerpasr.4994]

hi Graig, can you lead me to get an affordable good vacuum pump for residential use.please back to me at yours best convinience.

[@khorshidijaber4089]

👍

[@MLDIYSH]

What if the heat pump is on but the low side and high side are both cold/cool? I’m thinking the reverse valve too?

[@romarro4616]

I bet that’s a carrier unit

[@acservicetechchannel]

Not sure where we go that one from but the inside shots of the new heat pump were Carrier/Bryant/Payne thanks!

[@wasimedoo7994]

Love to get one of those book I don't know how to get one
