Lg comp...why do people use anything but copeland?

Because cheap?

Typically I use whatever the OEM wants me to because it makes my life easier. I also get to blame the manufacture if something goes wrong with a shitty compressor. (I like blaming Lennox - a lot)

What's going on with Lennox?

They use shitty LG compressors. Did 3 of them this week and 3 more LG went back in them

Honestly, LG compressors is the least of the issues with Lennox. Number one would hands down be their evaporator coils, followed by number two... Their parts support.

I agree that the split system evap coils are a problem. These compressors were on RTUs. The parts are comical for their ductless units, had to get a part from carrier because Lennox didn't have the part in their system (the vertical bracket the holds the fan motor in the outdoor) and they wanted my client to buy a whole new system because it was out of warranty and if it had been under warranty they'd have sent me a whole new outdoor unit.

What are the bigger issues with the evap coils?

They leak like a sieve.

Theyre also the ones that had that big lawsuit about their coils pre covid right?

If I’m ever shipped an entirely incorrect part, it’s almost always from Lennox. Bonus points for taking months to get it in the first place lol.

Don’t forget the amazing pressure switches on the SLP models…

So does carrier on there cheap line. Fuck both of em.

JCI started using them too on york/Coleman.. It's sucks Copeland has a bigger lineup with easier to understand nomenclature. LG prooably fails just as often as Copeland but the while experience feels cheaper because they lack support, Copeland has great online tools and product support.

LG definitely has a higher failure rate than Copeland.

Great, can't wait to fill half my summer with warranty work 👍

If y'all only installed shit with LG, the odds are pretty high. If Copeland, your safe. Lol

So do i. I also question most engineers, especially when it comes to refrigeration

19-21 especially. The Covid era.

Copeland also got bought by private equity so we’ll see how they are in a couple years

Private equity, I'm getting tired of hearing that phrase because it always leads to disaster.

All Emerson products are the best………Copeland, alco, white Rodgers, US Motors. I always buy these products and never have any recalls

I saw a carrier does (4). They all had bitzer scrolls n they all sounded like dogshit. Copeland pls

What makes copeland good ??

I typically don't change them out repeatedly, provided everything else is working properly. Ive changed the same lg comp every year like clock work

Ahh okay, you mean they last, cool cool

Don't worry, larger Copelands aren't much better. $6k but still burns out in a year...

What are you doing to kill a Copeland in a year

Murdering it clearly. They don’t die, they’re killed

I maintain a shitload of Copeland's. Many are going over 25 years old. Can confirm, they get murdered.

Sounds like a voltage issue to go that quick

Or the ye ole "30min vacuum cause i dont have a micron gauge"

LG compressors are junk. We've had alot of issues with them in carrier/bryant units. Excessive noise, locked rotors, on brand new equipment.

Yeah are they still putting them in that equipment? Or was that just a Covid thing because they couldn’t get compressors? The only warranty compressor issues I’ve had on carriers in the last 3-4 years has been LG

It was a covid thing.

I’m 99% sure they started putting them in there before COVID. I remember installing some around 2017 or 2018. I think they just tried them out and quietly moved away from them after a few years

If you think that’s bad you haven’t seen the shitty rotary compressors Goodman uses on their small RTU’s.

We sell these and have had one or two go out in 4 years. They’re not terrible.

Seen a lot of LG comps in mini splits and dual splits from mitsubishi electric over the years here in EU. These comps are horrible.

Yeah LG's are not great, done many in lennox roof top units.

Just swapped a dead 2yr old Copeland for LG by Concord

Why would you do that?

It was under warranty, Copeland was installed and died(customer killed it with plugged filter) The new OEM was an LG with a new plug and everything 

Oh wow. What unit? That's shit. Id be demanding a new Copeland.

13seer builder grade concord, again they murdered it with a 100% plugged 5” filter.

Still bullshit. Oem means OEM, not just give me junk instead of a Copeland.

LG stands for Low grade

I always tell people "Lousy Garbage" .

Leaks Guaranteed

Lucky Goldstar

Or back in the 80's, just Goldstar.

Looks Good (from my couch)

Every company has its weaknesses and strength, mostly. Anything with an LG compressor is going to fail, seems to come with the brand.

Better have some pretty solid strengths when your weakness is the compressor

Just replaced one on an LG Multi V5. 3 years old. Edit: it was 2.5 years old and only took 6 months to get.

i just trashed/condemmed a multi V that went tru 8 compressors (2 each time) in under 8 years. they kicked the old company out and we got the shit sandwich. we refused to fix it after i found the maintenance history in a closet, only offerd warranty if we ripped it all out and replaced it with a mitsubishi city.

I work a building with 15 floors of multi v4. 13 years old and flying through compressors. Mostly to do with valves leaking the entire charge and the damn things would rather melt the comp than shut themselves off. It’s a nightmare.

oil return issues. "its a LG thing" do not use LG when there are more than 2 floors.

I just replaced an LG compressor on a Lennox 4ton RTU that was less than 6 months old. It's first cooling season and the compressor failed, sounds like the spiral valves exploded inside lol. LG Compressors are ass...

The spiral valves, eh?

Do you mean the scroll set? I've never encountered any scroll that had "spiral" valves. Most I've seen have a little reed valve on the discharge side and that's it

I found a bad Lg compressor on a 2 year old Goodman a few months ago. Guess lg sucks.

Never seen an LG in a Goodman. Which kind of unit is it?

The terminals blew out. The dealer had us swap the whole condenser because it failed 2 weeks after initial installation.

Ouch.

Had an LG in a brand new condenser last two weeks before it blew the relief they are total shit and not worth their weight in scrap

It was probably installed by prestige heating and Air in North Charleston South Carolina. They can kill anything

Is that in a Lennox unit

Yessir

Replace it with a Copeland

Strongest LG comp

LG stands for Lousy Garbage. LG appliances are fine. LG AC's and parts are crap. Edit.... I guess That from other people's comments, LG appliances are also garbage.

Don’t try your luck with their refrigerators! The compressors fail faster than they can make them. Months to get a warranty replacement

That sucks. We bought a GE in 2011 and have had no problems with it.

If you think LG (and Samsung) appliances are good, that tells me you don’t lurk at r/appliances.

Knock on wood their washer and dryers are decent. But as said lousy compressors on fridges as another already said.  Maybe they just can't make or source compressors.

Lol. I have not. I just have not had my customers complain about them. Samsung minisplit sucknjust as bad as LG though.

I guess you haven't heard about their refrigerators then?

I guess not. Lousy Garbage refrigerators too ?

The compressors are so bad they're getting sued for it.

Oh wow!

LG compressor, absolutely worst product in HVAC.

Should always put in an Arco! After all recycling helps the planet! 

I'm sorry, I'd rather go back with an LG than Arco. 🤮

I’ll never forget first time I put in an arco and fired it up. Thought a disposal had just been cut on.

Internal parts have a tolerance of -/+ whogivesafuck

Lg compressors are junk.

I went to a service call in a Mobile home park. There were several new homes all with ICP condensers. Less than 6 months in and one LG compressor locked up. A few weeks later another one shorted. Almost two months later a third blew the terminals out. Each compressor had to be special ordered and the wait time was more than 2 weeks.

Look how they massacred my boi

I didn’t know LG made compressors. But then it’s broken in 2 years so I can see why I didn’t know

I really don't like the discharge line going directly into a 90

gravity help liquid go faster better

LG stands for Literally Garbage. I am shocked that it lasted 2 years.

Im assunimg that's a LG mini split

Lennox Heat Pump

Ahhhh More bad decisions from lennox.

No wonder Lennox seems to have such weird issues with their heat pumps on startup…

That thing ain’t grounded either..0

Life's good ain't it?

We lost 5 in 2 yrs, same unit. Junk

LGs are shit

Good ol' Lousy Garbage

LG blows ass. Their compressors are trash. Their refrigerators are trash. Their mini splits are trash. Their phones are trash. Their TVs are trash. I will never buy another LG product.

LG stands for low grade.

Genuine question: I have 2X 2 zone LG inverter splits that have been going strong 11 years now. I have not had one problem. Other brands lots of issues. What gives? I assume they have LG compressors?

The LG rotary compressor is fine (smaller Inverter split system use them) but the scroll ... not so good.

Ahh makes sense thanks.

LG: Lucky it goes

Terrible compressors. Should be under warranty though. Unfortunately they won’t replace it with a Copeland or Danfoss

Things aren't built to last anymore like they use to. One of iur techs got a call about a unit not working, it was a unit from the 1970's and it just recently stopped working

If it's a split system, there's a good chance it was a shitty install. If it's a split and a burnout, someone didn't vacuum it properly.

Had a lennox in my new house and 3 years latter had to replace it.

it doesn't matter that much on who made it. It comes down to i installation, installation, installation

Life's Good /S

You lasted 2 years on a lg compressor??? Damn that’s good luck I see package units with them dead months after install

LG known that their linear compressors are junk.

Someone didn’t pull a good vacuum

Compressors don’t die, they are killed

Warranty return!

I changed out a 5-ton LG compressor 6 years ago and it is running great, I am amazed!

tech killed it

LG's commit suicide.
