Carrier RTU Start-Up From Hell

[@jaymartin5095]

Thank you for taking us along. I know it is extra work for you, but it really adds value to anyone trying to learn.

[@HVACRSurvival]

That’s what I’m hoping for.

[@sterlingarcher46]

My goodness the wiring on a brand new unit oh boy ! I don't pretend we make anything better over here , we all have our own issues but them wires dangling everywhere with no conduit , no protection not even zip ties ? That's just mind blowing to me !

[@HVACRSurvival]

Do you guys make much HVAC stuff? I know I’ve seen a boiler but that’s about it. I don’t see much of anything made in France around here except high end clothes type stuff.

[@sterlingarcher46]

@@HVACRSurvival There are a few companies , RTUs , AHUs boilers etc but most have been bought out by the big guys . Trane does have it's EU factory over here though , they make chillers for the EU market .

[@HVACRSurvival]

I have no desire to see the Eiffel Tower, any of that stupid shit but I would like to see some of the different things that are done over there like some of the different plumbing fixtures, door locks all kinds of weird stuff that I don’t get to see here, which I see it in some videos. It’s just funny how things can be different when on a global scale. And I don’t mean any of that in a bad way, you should know how I talk by now.😅

[@rayraap3905]

After seeing this video, I would think twice about buying a carrier. Really enjoyed this video.

I've heard techs say all are about the same now days. All our Carriers have failed at one time or another

[@Paul-IE-Repairs]

@14:40 i like how all 3 fans are set at a different depth, by just looking at the shaft protrusion difference

[@fshn76]

Sad that you spend that much money on a unit and still have issues. I have had my Jumper King pretty much since day one and love it. Makes it so much easier to troubleshoot. Good video Rick. Have a great Memorial Day.

It was good, thanks for the support!

[@watermanone7567]

Boy has Carrier gone downhill since I did service work 20 years ago. I don't know who is good anymore? They must spend a ton of money fixing their mistakes in the field. Thanks for a great video.

[@HVACRSurvival]

Thanks for checking it out!

[@mikewithers299]

It's actually the customers that have to pay big money to fix the problems. We got all Carrier chillers at work, and all of them have failed at one time or another. The newest one is 4 years old

[@jasonjohnsonHVAC]

The quality of that equipment seems questionable at best. You did better than most do, thats a fact. These manufacturers seem to have abandoned quality control all together. Just installed and did a factory start up on a Trane Intellipak yesterday. It was put together nicely, but it definitely wasn't without its issues. Another quality video. PS.....I enjoy the rants....you are speaking fir many of us without a public following

[@HVACRSurvival]

Oh, I should make a private channel where I leave all that in because that was nothing lol there was a lot more

[@gabbertje2811]

I agree with the lack of build quality. In January 2022 I installed a Trane CXAF heat pump and then assisted the Trane technician on the startup. The startup went relatively uneventful but the engineer already scratched his head a few times because Trane had changed some things including a poorly documented lockout input. One of those things was that all four crankcase heaters were connected to a single relay and got switched off as soon as the unit went into run. We already guessed that this was going to cause problems but it was designed this way. Out of the 4 compressors they already replaced 6 🫠. The first one went within 72 hours. The second one (on the second stage) went as soon as the first one was replaced. They also had to replace the main control board and had to come back at least a dozen times because of lockout situations of different kinds. We took the 5 year maintenance and warranty plan so not too much worries on the repair costs but the downtime is very annoying and expensive. We had to make sure we always had heat so we were forced to install an additional heat pump and backup gas boilers which had cost us around 40K to do. After 2 years and 4 months we're still experiencing trouble with this unit 😔

[@jerzyaheardz6939]

Thank goodness Carrier moved all their factories out of America, it really improved their quality and quality control…..

Bingo! I cut out what I said about it.

I would like to think the equipment problems were unique to Carrier and an assembly plant, but it probably is an industry wide situation. Excellent decision to get the Carrier warranty. Excellent video. Hope your drive was relaxing. It looked like beautiful country

It was a good drive. I wish I could have shown more.

[@christiansommer914]

Uncle Rick for the save.. Yesterday I was trying to explain my apprentice about the filling chart with the line.. Now he can watch your video.. Great video and keep being you, love the you explain things.. BTW. About the drain, looks US standard, but don't you ever use drains with the little orange ping pong ball.. Then it doesn't matter if the drain dry out, because the ball will prevent air from going in the to wrong way. And filling the unit with water.. Not sure if this is the case with RTU's but it is on big ventilaton systems.

[@HVACRSurvival]

I flooded a ceiling thanks to one of those junk traps. I put it back together wrong😟🤫🤦. Thanks for the recommendation!

[@HVACRSurvival]

🙏 Thank you very much! I really appreciate your support! You probably would’ve liked the full video that was over 2 hrs prior to heavy cutting.

[@PeteGaughenbaugh1]

Whoever decided to use zone dampers on sock duct is going to regret it. Those things need to be set up for the fans to run constantly during occupied mode. If the fan is allowed to cycle on and off with the call for cool/heat then every time that zone kicks on, it’s going to sound like someone cracking a bull whip as the zone inflates the duct.

[@throttlebottle5906]

maybe they're set to ramp up real slow? they are ECM after all, so I assume there's a setting for that, as well as continuous circulation.

Hey Rick. Another great video. Another great example of why I say you are a difference maker!! Love that opening guitar riff too!!🤘🏻🤘🏻

[@HVACRSurvival]

Thank you!

[@PeteGaughenbaugh1]

Rick, I just did a replacement of 32 Carrier RTUs. The same mixed air temperature sensor was broken in the same place on 11 of them. Thankfully, they were nothing more than a SPST “safety” that wet could put a jumper across to make work. Some that had electric resistance heat kits (field install) came with wiring harnesses that didn’t fit anything, anywhere and had to be rewired to work at all. Same unit model, same heater model, didn’t know from one to the next what’s working or needed redone.

[@HVACRSurvival]

I cut out a lot of my feelings on how this thing was built and designed. We are a Carrier dealer so it really looks bad, but whose fault is that? We didn’t build it. 🤔 I didn’t call Carrier out like I did Mitsubishi….at least far as you know 🤫🤫😂😂

On the fence with that jumper box, but your video may help make the decision easier. As for the resistance substitution box, it’s an old idea. Trane has rolled out Symbio 700 for the Voyager units, and it’s all Bluetooth. No more jumpers. Great video as always Rick. Thanks for sharing.

Wow, I was thinking going Carrier after my 2007 R22 Trane dies due to cost, I don't think it's worth it now. I just wonder if Trane also went down hill as well, I would assume so since almost everyone has.

Build quality is on par with a 2024 model year vehicle 😂

[@elBusDriverKC]

I have the Zebra stat. It works well and all but it's bigger and doesn't have any fancy connections and didn't come with magnets. I had to JB weld some big magnets on it because it's pretty weighty. It does have built in activity checker (which can let you know if the thermostat is calling for heat / cool etc...).

[@joeg3218]

I agree, that brand cut many corners!! My school apprentices tell me on the residential line on that brand how horrible the quality is. boards bad right out of the box. Missing parts. I had a unit where the condenser fan blades would fall off....

[@jrsmyth9761]

High and low settings for the economizer is only available if the Jade is set for 2 speed fan. When there is only one set point available, then Jade is set for single speed fan.

[@HVACRSurvival]

That makes sense. Kinda weird it wasn't set up for that with it being ECM. I didn't have time to read over the manual this day. But I just did a Siemens controller recently and I believe it said to set it for single speed.

[@jrsmyth9761]

Yes, it does seem odd that it was not factory set for 2 speed fan!!! Everyone that I have done has been 2 speed from the factory. However, with the crap you found on those units, it's no surprise. As for the Siemens, went to the Carrier dealer gathering and they were promoting them. Seems like they are a combo of Belimo and JADE. I think the neat thing is the ability to have NFC via the app and have saved set ups. Then all you do is upload the save settings to the control. I believe you can save multiple set ups.

Thanks Steve!

[@henningquast8456]

I must say, I’m really surprised to hear and read all the issues with the newer Carrier equipment. Since I’m from Germany and mainly work Chillers I’m not really familiar with Carrier package units (only their chillers which have a god awful controller). I‘m mainly dealing with manufacturers like Ciat, Galletti and since about a year now all our new chillers are Skadec, which is a German company who really go all in on quality. It of course has its cost but they are really thought through, high quality units and also highly costumizable. They offer gliding free cooling, heat recovery, inverter controlled Bitzer or Bock reciprocating or screw compressors and a freely accessible controller.

[@Ted_E_Bear]

Awesome video !

[@MikeB9771]

Thanks for the video Rick, you convinced me that the Jumper king is worth it when i seen it in this video. I have seen it used to find low voltage shorts as well. We too have guys that complain about having to work past 4, i work til the job is done. I get paid no matter what time it is, for us anything past 4 is overtime which is nice.

Ground source (geothermal) can be great if the engineering is done with data not assumptions. Over 15 years ago I was involved with a project using ground source hydronic heat pumps. They didn't do a thorough evaluation of what the ground temperature was the before the project. It turned out that the aquifer was apparently glacial feed. In operation the supply water to the hydronic heat pumps was in the forties. The heat pumps were constantly tripping when the system was operated as designed. That project was a nightmare that had a lot of problems. Some examples are 100% outside air AHU that they value engineered out the heat recovery coils. There was a second floor glass enclosed lobby with no mechanical cooling that they value engineered out the high efficiency glass. And there was back to back double sash variable air volume fume hoods with a single fume hood control damper that the hood face velocity could not correctly controlled as the hood was designed. The hood manufacturer had to redesign and retrofit the hoods. They basically eliminated the separator between the sides. (And we had internal problems. Poor work quality by our electrical subcontractor. And we had a supervisor that threw my coworker under the bus. My coworker did nothing wrong. The problem was the hood design. This delayed the correction of the problem with the fume hoods.)

That is some really crappy quality in the manufacturing of these units... If I had gotten these delivered, they'd be right back on the way to the factory within 15 minutes of arriving. But what are ya gonna do if they're already installed. Just gotta deal with some manager's penny pinching so that he can get his 2nd Ferrari a day sooner... Really great marketing material though. Shows they care about the customer a whole lot

Just another piece of equipment outsourced to another country to be built for less labor. I cut out the part that these people generally send their family members when they don’t show up to work and they don’t know what they’re doing. And this happens at Ford and several other factories that have left my area.
