Variable Compressor Diagnostic and Replacement with Inverter Board on a Heat Pump EP201

[@NathanZSolomon]

Non-HVAC person here. I just enjoy watching HVAC people diagnose problems and try and follow you all. Most times I can't, but I try. Wishing you well as you deal with these many different problems. It's almost like the various murder mystery TV shows. I try and guess who killed who and with what. 🙂

I've bee in this field since 1980 and was a Carrier Bryant dealer. I will not sell inverter communicating systems no matter how much rebates or fake savings advertised. Whatever you save in electricity you will pay it all back and more in repair bills. Too much electronics, pricey inverter compressors, ECM condenser fan motors, too much bullshit for what little savings. Buy the way Great Video!

[@woodystokes1543]

Tech tip as deliacate as they are I would never repair if any chance of rain. Nice work 😊

[@Elruido702]

Been enjoying your videos im new to the trade i started as a maintenance tech and now a service tech thought i had what it takes to be one... Boy am i in for a treat this summer, thanks for the upload

[@stevencossaboon3237]

Great job Nighthawk.

[@hvactechwanttobe1499]

Thanks for sharing the video

[@sknight0391]

That definitely sucked. But you did a great honest job on it. 😎👍

[@rashpalsingh9880]

thanks for sharing, looks like it has Suction dryer , maybe this is third compressor?

[@ronchambers9762]

Make no mistake. That homeowner got screwed the minute they said yes to that garbage. It does not and has not ever required that much technology to heat and cool a home.. SHAME

[@DonTgurdy1488]

Agreed! Inverter units are totally not worth it. The up front cost is higher, most of the parts are not universal, most technicians don't know how to diagnose them (and that's not their fault most of the time. The training for these is terrible), and once that 10 year warranty is gone, any repairs are going to cost big time.

[@john7017]

I agree and will not sell that crap

[@DonTgurdy1488]

@@john7017 I'd say the only time I would ever use an inverter system is a self installed mini split. They are Soo cheap that if they fail, you can just install another one

[@Samlol23_drrich]

100% agree

[@Hvacnc]

Good job bro

[@woodystokes1543]

Tech tip Friday I never unsweat the compressor there is always enough copper.😊

[@DanT271]

Wow! That's some expensive equipment I would rather for my house. Just have one that is either on or off. No inverters. No fancy stuff. Any energy efficiency saved would be consumed by repair bills by far

[@timwhite8500]

Not here in AU. Everything is inverter based. Direct Online stuff went away nearly 20 years ago. Nobody can afford to run old dinosaurs here.

[@ronchambers9762]

That's crap

[@timwhite8500]

@ what’s crap?

[@ronchambers9762]

@timwhite8500 it is crap that no one can afford to operate more reliable equipment, but they can somehow afford to pay 4 times as much to purchase equipment that requires 10 times more service. That's crap

[@victorsr6708]

I’ve been in the HVAC industry since the 80’s. My favorite furnace is the 80% two stage. With that said in the last five years I’ve only installed heat pumps with inverters. Once you master them they are awesome. The key is the installation and commissioning

[@SombraLocs]

Why did it have a surge protector on the air handler?

[@rpsmith]

What is the tall base this condenser is mounted on?

[@NighthawkHVAC]

Its raised off the ground so when the unit defrosts the water doesn't refreeze onto the coil.

[@rpsmith]

@@NighthawkHVAC -- So it's OEM or aftermarket?

[@NighthawkHVAC]

After market.

[@rpsmith]

@@NighthawkHVAC -- Great! Thanks!

[@john7017]

Heat pump

[@GlenS123]

Our trade has lost its mind, how much energy has this system saved? Not even close enough to cover a repair where parts are under warranty!

[@john7017]

You are correct!

[@Samlol23_drrich]

It’s all brainwashing of “do gooders” who think they are saving the environment” cause that’s what they’ve been fed by people who profit from this

[@TimmyYapYap]

Nighthawk!!

[@SombraLocs]

Was that compressor grounded? I thought anything over 0.5 Megaohms was considered good. You were reading like 8.1 Megaohms.

[@jasonjohnsonHVAC]

Use your recovery machine to pump the rest of the refrigerant in. You didn't show it.....but did you open the indoor EEV for vacuum or put it recovery mode.

[@HVACR559]

I's a Carrier riding on their name. They put a TXV on the air handler of this expensive beast, there not worried about cooling efficiency. The inverter and EEV are outdoors to maximize heating efficiency in heat in heat pump mode,

[@YoJewFriend]

At 15:04 you just showed us the problem and never noticed what it was. That’s a suction filter dryer. Should have pulled it out of the system. Might have been what killed your compressor.

[@NighthawkHVAC]

I thought it was a suction line drier at first. Turns out it’s a muffler.

[@elijahgoodman3140]

So maybe I missed it but was the compressor with the high voltage plug only the correct one? If so, what did you do with the low voltage plug? Great video!

[@realSamAndrew]

So was that the right compressor afterall? Was there a modification? What happened with that support request? You never showed any of that, only the new one already in with the blanket covering it.

[@Ageehvac]

Your opening the system while it's raining? Your a wild boy....

[@Ageehvac]

Great job though

[@josegaytancruz5246]

The compressor is the only item under warranty. What about the labor costs?

[@NighthawkHVAC]

Correct. The board and the compressor was under warranty. The labor was not. But the labor cost shouldn’t be $20k.

[@ronchambers9762]

@NighthawkHVAC but the next time it fails, which won't be long, it won't be in warranty, and the customer gets screwed again. SHAME

[@nickv255]

​@@NighthawkHVAC the labor should be 20,000 usd?

[@NighthawkHVAC]

Shouldn’t be. Sorry typo.

[@realSamAndrew]

​@@NighthawkHVAC how much was the labor, ballpark?

[@HVACR559]

Carrier customer service sucks. In the old days when everything was electromechanical that was okay, but now with all of the electronics customer service is essential. I had them tell me the same thing on the control screen of a VRF system. I get the replacement screen and they insist that is the right part. Customer plastered the hole in the wall where the old screen was, because the new screen went on an arm. Finally get a hold of them because it isn't working, they realised that screen needed another $900 module between the ODU and the screen make it work. 9 months later we were were installing the original screen that supposedly wasn't available. TXV indoors doesn't surprise me. I just installed a NEW R-410A Commercial RTU with a AccuRater's I thought fixed metering devices were behind us SMH. AccuRater's are planned obsolescence!

[@timbrown9305]

Been in HVAC/Boilers for a long time. So completely tired of the industry screwing my customers. Many have used standard single stage units in incredible homes and they are money ahead considering everything. They are sanity ahead of having systems last 20 to 30 years. The other customers were warned. (Infinity!!!) if any of you remember that carrier trainwreck. I warned customers to wait... most did, other lost $10,000 when all said and done with discounted new stuff. Still feel upset.

[@jasonredman2265]

Why not just get a whole new condenser? Bad inverter bad compressor, means Bryant owes that customer a new unit!

[@NighthawkHVAC]

I tried. They said no.

[@victorsr6708]

If this was a Daikin fit they would have given him a whole new condenser, 12 year warranty

[@tyl8ter]

20k??... Comment, from Clarkesville GA

[@NighthawkHVAC]

I know that's ridiculous!

[@garfigator]

He still didn’t explain why the 3-amp fuse blew, and he condemned the compressor without a valid reason.

[@texkarlitoes]

compressor was grounded. Its good practice to replace the board with the compressor.

[@shadowbanned69]

Well I'll never buy a Bryant p.o.s that's horrible cust. Service and apparently they lie to you to sell the wrong equipment.

[@shadowbanned69]

And that's why I still to this day buy all nordyne branded equipment. Cheap, reliable, and easy to find parts. Yup

[@coldfinger459sub0]

20. Grand would be faster to swap out the whole outdoor unit.. and be on your next job making more money. Than pulling the compressor flushing the system. (“PROPERLY”) lines and evaporator of old oil.
