@@TEXASLOYAL I mean the commenter is the one claiming all HVAC school teaches is heat pump components and functions, not the creator, the person you tagged. Mistake or?
Excellent video! I have this same heat pump. It didn't work well below 40. Just figured thats how they work. Then I got to inspecting it more. I found the defrost temp sensor on the coil hanging out of the little tube.... No wonder it wasn't defrosting properly. I zip tied it back and now heat pump works much much better.
For sure took me almost 4 years of watching these videos to install split myself, now thanks to these videos I know how to save lot of money doing my own hvac diy work as a proud homeowner.
Awesome teacher and great videos. You have helped me tremendously in switching careers. Best thing I've ever did. I like my job now...haha wouldn't have thought it possible.
Great info, Craig if you want to pressure check that outdoor unit lets say after compressor replacement or leak check, due you have to shift the 4 way valve to test complete coil?
At 8:40 you mentioned that a Thermistor operates the same way that a Type-K Thermocouple does. I fear this may be a little confusing. Thermistors change their resistance value at different temperatures. Resistance may decrease or increase depending on the type of Thermistor. RTDs are similar. Thermocouples create a tiny current which changes with temperature. They are both temperature probes but they do so using completely different effects. Thanks for the great content! I really like your video. It's excellent. I learned so much.
Hi Craig .I am an air conditioning installer here in Texas .Could you translate your videos into Spanish that I can understand better.As I also have many friends of mine who do not understand English well but would love to learn from you.I consider it the best teacher and I would like you could HELP US .I say this on behalf of many who ,like me ,would love to be able to improve ourselves in this profession,thank very much.
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.
Hey Craig, was wondering if you could do a video on mismatched indoor and out door coils and efficiency. Maybe you could explain how pressures and superheat may change. Thanks!!
PLEASE HELP I have a heat pump that was sucking down at the outdoor txv and I replaced it. It still won't heat. What could it be?? It comes on for about 4 min then shuts off. Brand new

So with my American standard gold 17 5 ton 2 stage heat pump is coding for the TXV or low refrigerant even though confirmed it is not low of refrigerant does that mean there is a 99% chance it is the TXV? My heat pump the TXV looks like it is electric expansion valve because the thing you were pointing to calling the TXV on that one is just a bundle of yellow wires connected to what looks like a solenoid of some sort that has a bunch of copper tubing on the other side of it. And it also has an accumulator at first I thought it had dual compressors but apparently it has a two-stage single compressor with a accumulator on the side. I wonder how much it would cost to have a tech replace or repair whatever is wrong with my TXV because of the run in cooling mode but not in heat mode because when it switches to heat it cuts out on overload high head pressure.
I hate to ask this on this video but do you have any videos on troubleshooting dehumidifiers? I got one that trips the breaker on starup and you have such good info and troubleshooting videos so i had to ask. As always thank you for all the knowledge you share and great videos. Thank you sir.
A dehumidifier is just an AC optimized to condense moisture out of the air as it flows over the evaporator, generally by reduced airflow so the air has more contact time. So just look at videos on finding shorts in AC systems, they'll still apply.
Great video. But I'm saddened at how immensely complex these systems have becoming in recent years. They used to be so simple and easy to purchase and swap out parts. Now their complexity makes it harder and harder for DIY servicing. With so many intricate little parts and subsystems, there is a far greater chance of something going wrong, which means a far higher chance of having to maintain a yearly budget for calling out an AC repair person to "service" a unit that is supposed to last at least 10-15 years (20 if well maintained). In Florida, I may turn on my heat briefly *maybe* twice a year, if that. Why would someone want all this complexity with so many parts that could fail when they could instead have a simple electric coil furnace for that couple of days when its needed. The so-called "energy efficiency" argument is meaningless when it is almost never used, and electricity usage would never be enough to outweigh the additional cost of an unused heat pump system.
A good argument for mostly warm climates. In that case, I agree. I would just do a straight A/C system without the heat pump, and use electric (or gas) for occasional heat use. Disclaimer, I do multi-unit maintenance. I'm not an HVAC guy.
I agree with your argument, however it’s not that hard to learn. I am not hvac tech but like hvac as a hobby, this indeed takes time to learn, but once you spend maybe 4 years diy it yourself, it becomes a lot easier. In Florida yes don’t make sense just grab ceramic heater for sure.
@@acservicetechchannel yeah but what I've seen isnt what I'm looking for per say my unit has yellow red purple blue and black common sense tells me hook the same color to same color well I got three more colors that have to go somewhere Idk if two wires go to one or what or maybe they not used at all
Here in Phoenix, I've never seen anything but heat pumps, and I was in construction for more than 30 years. Heat strips are commonplace, but there's little use for anything but a heat pump in the great southwestern states.
Could you please tell what is the minimum safe ambient temperature to turn on air conditioner. Is cool temperature going to do any damage to the compressor or it's a myth? Thanks. (Not heat pump)
Man I’ve never heard anyone be able to explain the capacitor that well and simple

My heat strips come on but not my heat pump. The ac comes on fine. What do you guys think?
you are amazing !! thank you
Could you please upload a video just troubleshooting a mini split all components how works step by step
Do you have any videos on bearings , bearing lubrication systems. Different types of drive systems and belt and pulley alignment?

Thanks!
Why do some units, usually Trane in my experience, come with a start cap and potential relay while most others just have a standard dual capacitor?

So nice of you
Thank you
You're welcome
thanks a lot for this great video , i want to ask you what is the function of the indoor unit coil temperature sensor in a mini split ductless A/C ?
It’s function is to sense temperature 🤒
I don’t work on many heat pumps. Do you use the true suction when reversing valve is engaged or in normal position. Thanks
thank you!
You're welcome!
Hello, Do you know just by any chance what the DT is looking to get in defrost mode. Can you talk a bit about that if you can. Thanks

Check the compressor first. De-wire it and see if it still trips

Do you get monoblock heat pumps over there?
Damn that was good
on 1:28, you mention that front seating the valve will connect the 2 pipes. Shouldn't front seating those service valves close the line?
It will close the tubes but the port will still be connected to the tube heading to the indoor unit, thanks!
Do you have a book on refrigeration or commercial troubleshooting?
At this point, I do not, thanks!
I just wanna lwarn to fix them, not how theyre engineered
