Goodman System Not Cooling Due to Major Issue | HVAC

Double wide trailer not cooling due mainly to dirty evap coil but I found something else slightly concerning out at the condenser. it felt like the right thing to do in my opinion and I was trying to cover as many bases as possible to get the tennant as cooling as best I could.

A smart, honest, and conscientious young tech like you, with exposure via youtube ... you'll be getting job offers. You should be thinking about what part of the country you'd like to live.

[@AB_HVAC]

🤣 thanks man, I'm currently thrilled where I'm at

[@gordonpotts753]

U done good. U gotta remember when the unit is overloaded the subcooling will b low. As it catches tge load the subcooling will rise.

[@AB_HVAC]

I figured that, I just wanted the superheat down enough to atleast get the lineset sweating

[@petmogulsupplies6631]

i wouldnt have added any gas, i would ve just cleaned the condenser real good. nice video by the way

[@dogdiggingrj2089]

Nice to watch a honest tech not acting like you know everything when not sure asking for help

[@AB_HVAC]

I do my best to not sound like a know it all. My boss says I come off like that when I ask him questions, I'm just genuinely curious cuz I love the job. I got no problem if yall call me out on legit bs

It’s not non rinsing. It’s self rinsing on the evaporator when it’s condensating says it on the bottle I’m pretty sure

[@mrautoguy8419]

Great video! Great tips!

[@AB_HVAC]

Thank you 🙏🏽

[@ccthepope]

From what I understand a TXV has to have a full column of liquid feeding it to work correctly and adding that half of a pound might have made that column full so the TXV started opening up and dropping head pressures. I have seen others add just a little to see the TXV reaction. I guess that is where a sight glass is worth its weight in gold. I really enjoy your videos!

[@AB_HVAC]

Thanks man

[@markcotter2355]

good job Austin

[@AB_HVAC]

Thanks man. I wasn't trying to be a dick in the comments 🤣 some shit just gotta make sense to me for me to agree

[@chrisdevine5328]

You can mount the bulb vertical but it NEEDS to be stem up

[@LadariusCapersOfficial]

That system needs some love 💕

[@AB_HVAC]

You ain't lying. I did what I could though.

[@drewtab18]

I have that same manifold

[@AB_HVAC]

Honestly I think most people do 😅 it's the only manifold I see on a Facebook group chat I'm in

[@dreamer19741]

Great video! I’m just starting my career in hvac. I’ve learned a lot from you thank you keep them coming! I do have a question for you, 5 years ago I used seal easy on my system. House is not getting cold like before can I use seal easy again on my system I feel like doing myself…thanks new subscriber

[@AB_HVAC]

Nah man, if you used easy seal and another leak came up I'd go ahead and try to get it repaired if possible or replace the system. Idk the price of refrigerant in your area but if you have a R22 system you're gonna be paying an arm, leg, and nose just to fill it up

Wow, that thing was nasty!!!

In that situation with the high head pressure and it being 100° outside, but superheat high and sub cool low (after evap clean), would start by cleaning that outdoor coil like you said to try and lower the head pressure, especially you saying lack of maintenance on rentals for sure. Then once that head pressure lowered I would still be looking at that subcool for low charge. If that outdoor coil caused that head pressure with normal refrigerant levels it would eventually lead to a high subcool overtime with the txv. 100° outside in the southeast we would see about close to a 380-390ish head pressure possibly outside. You sounded like you were going the right direction. And the 150-160° suction is normal for that high load inside. I keep editing as I watch the video. As long as the txv bulb is mounted securely and tightly, then it will do its job because it’s just refrigerant in the bulb reading a temp. If the bulb was dirty and poorly mounted it would cause more refrigerant than needed to enter the evap

[@renj6531]

If only the homeowner knew how to clean it my landlord refuses to to pm id clean the coil my self but its a package unit up on a 30 ft roof … no thanks

[@AB_HVAC]

I like how you kept editing as you watched the video 👌🏾 thanks for the reassurance.

[@Bill_CBR]

"Sales Techs", that's a great term. S. FL is filled with them. I haven't met a real technician.

[@AB_HVAC]

They're everywhere. Thankfully being where I'm at dealing with the super cheap property management's, I'm forced to learn these systems and repair them or bypass stuff to get people going while we wait for approval. I remember I was thrown in front of a 1980s Rheem electric air handler, first winter at this company on a section 8 apartment complex. I took the panel off and found nothing but fan relays, heat strips, terminal bars, and 90-340 relays. I was so confused but after about 30min of just remembering the basics and following voltage, found a bad relay and got the unit back working.

I stay in a mobile home and have a TXV as well. But my evap definitely will never look like that 😂

Lol keep it that way or you're gonna have problems man

[@drodriguez394]

Use measure quick you can zero the probes

[@AB_HVAC]

Well when I take them apart and blow them dry I do find moisture in there so I just chalk it up to that

[@drodriguez394]

@@AB_HVAC I’m sure that’s true they’re supposed to be water proof to a point. Try measure quick if you haven’t already I really like it over the field piece app. Great app for young and even seasoned techs. Helps you diagnose you’re able to zero pressure probes and calibrate clamps in ice water. It’s awesome

[@AB_HVAC]

@drodriguez394 ill give it a shot over the weekend

[@Mo4Honesty]

I think you have your guidelines backwards. Txv works off of head pressure? The bulb measures superheat which is evap pressure. Then you say if subcool is low clean the condenser. Dirty condenser produces high head pressure which normally gives a high subcool, which makes you look OVER charged. That's how I heard you and it sounds backwards. I don't know what should have been done here (unlike the armchair geniuses) but I was just clearing up the rules of thumb as I understand them.

[@AB_HVAC]

Yeah I did jumble that up. I guess what I meant to say was when dealing with a txv you look at the head pressure side, because your head pressures sat temp and liquid line temp determine subcool. That's my bad.

[@Mo4Honesty]

@@AB_HVAC that's ok we are all trying to learn (I hope most are here for the right reasons). But again, if you have low subcool, on a txv, you are not overcharged, so that is still confusing. Care to elaborate?

[@AB_HVAC]

@Mo4Honesty I wasn't the one saying I was overcharged someone else was. At first my gauges were reading like around 150/470 and a 30° SC and -1°SH. After cleaning the condenser it was running 1° SC but I was at a 30° SH and a 80° SL temp. So I added 1Ib and got the system to start sweating the suction line at 72°, 15°SH, and 2°SC

[@AB_HVAC]

@mikez1968 check the video at 10:38 and tell me what the manifold was set to read pressures for which refrigerant

[@user-tx7ce4lq1y]

@@AB_HVAC I checked it out at the 10:38 mark. @AB_HVAC 2 hours ago @Mo4Honesty I wasn't the one saying I was overcharged someone else was. At first my gauges were reading like around 150/470 and a 30° SC and -1°SH. You never had a 30 degree subcool. It was 1.2 degrees. Where did you see 30 degrees subcool?

[@HVACK]

dang, bo, that's nasty!

[@AB_HVAC]

Wire brush got it back workin tho!!!

[@dkinfishing]

I don’t think the system was overcharged I think you just had lack of air flow…. Even though it’s subcool metering device you still need proper airflow. That evap and I’m sure the blower wheel was just as dirty, you did what you had to do, but I don’t think you need refrigerant

[@AB_HVAC]

That's a fair point. I definitely added that to try and make up for it because I know that coil wasn't 100% clean, maybe 80.

[@AB_HVAC]

Only thing I could argue against that would be since the pressure was high and superheat was off the airflow couldn't have been affected from the blower motor too bad but definitely a factor

[@dkinfishing]

@@AB_HVAC yeah I think your superheat was high due to restricted evap and probably blower… just my thought

[@AB_HVAC]

I can respect that. That makes sense

[@AB_HVAC]

🤣🤣 dude said he put filters right over it when he moved in

[@MetalDetectingwithCZkidd]

Your wrong! You mumble to much too.😂😂😂. Did you check the incoming side of the air handler coil? You didn’t clean or help the evap at all. Nice effort though. Had you checked the incoming side of the coil, it will be packed. So, your system is overcharged. Simple. Thats it. As well, being the evap coil is plugged, knuckleheads before you tried adding gas to get the suction pressure up. No bueno. Condenser coil needed a quick wash and fins straightened out. Good on that. So before you start on the wrong path of sub cools, superheats, temps, and all the deep stuff, and get yourself mumbling, get to the simple things first. 99% of the time it’s the easy stuff that is the issue. ( plugged evap coil). A quick inspection will get you started on the right path to a positive result. Nice vid. Enjoying them.

[@AB_HVAC]

It's a downflow unit. The side you seen me clean off is technically the incoming side genius. Not all air handlers blow up or side to side, there is an orientation called downflow
