Well done! I'm from the old HVAC school. 44 years in the trade and as long as i have stayed open minded and teachable, I learn how to do this job in easier and safer ways. Great video young man!
hello sir pls help i forgot to turn off my heat pump while renovating sanding the kitchen i have central air vents in the kitchen mu question is does the vents in the kitchen sucks the dust and can spread into the whole house?
@@fluxcapacitor8416 in my experience the supply air register in your house ONLY blow air. The only register that has the ability to "suck" air is the return air grille which is taking air from the house back to the air handler or furnace. Keeping your air filter (s) clean by replacing or washing them on a REGULAR basis will help a great deal in keeping your air and HVAC system clean and running efficiently.
Hey men I’m new in the HVAC business and I want to thank you so much for everything that you have teaching us and again,I want to thank you for everything you have taught me. GOD BLESS YOU ALL MY BROTHER
There are so many shady people in this industry ripping people off. Most of these so called professionals should be put out of business. Telling homeowners they need a whole new unit when a low cost replacement will do. Love the channel and educating us on how to do repairs on our own equipment. If these companies and the people that work for them were honest we would not need to try and learn it ourselves.
Yep I was low on R22 on an 18 year old Bryant. r22 leaks over time just like all refrigerants. Even the EPA cert teaches you when you study that no system will be 100% leak proof and all systems eventually need a recharge. Instead of offering to leak down test and recharge with r22 which believe it or not is still affordable when you buy it yourself, he wanted to upsell me a $12,000 brand new unit installed. I know the AC is about $3500 alone brand new and takes about 4 hours to install if your good. So why should I pay you $8000 extra? That is why I got my EPA cert so I can just do my own damn maintenance and I have learned about Goodman. I dont need a whizbanging 4,000 Seer super inverter mega zone 3 Million Super X AC. I just need a damn ac to blow some cold air. I can fix it when it breaks oh whoopie do! That HVAC tech could have made up to $1000 if he would have done honest work for me but he tried to take advantage of me and I bought into his scheme at first but was hesitant to accept it so I slowed down and did my own research boy what I learned during this process.
I love what do. Sharing your knowledge in a way anyone interested in learning can follow you with ease! Again, thank you. I know it’s a lot more effort to complete a job like this and getting all on camera and it’s appreciated.
@@diyhvacguy, agreed! As a new subscriber, I've been watching so many of your videos now! It would have been nice if your material was around when I installed my unit. I did not know to do HALF what you've done, the tools you use etc., but I was never in HVAC. There was only central heat for the slab & the system blew the air underneath it. It kept your feet warm but that's what slippers are for! It was horribly inefficient by that time so I tore it out, filled everything in with concrete and installed a split central heat and air system. A friend told me his family member worked in HVAC & he had a sheet metal brake so I provided him with sheet metal and measurements so he was kind enough to form the pieces of my plenums. The spaces I had to work in were small so I had to take them in as "panels" and then assemble, seal & insulate everything. I cut/installed the collars, boots, flex etc., ran the lineset and brazed the connections. I utilized a 240V outlet from the living room intended for a large window AC unit and routed it to the outside with the "disconnect" box etc. I only needed to borrow a vacuum pump & the unit contained ~15' of lineset worth of refrigerant and I've been having ~20° difference at the register compared to ambient. That's been over 15 yrs ago and thankfully it's still going! As for maintenace I've simply kept the air filters changed, I've cleaned the inside/outside coils and I replaced the capacitor at the condenser. There was a hot day where it didn't start so I opened the panel and saw the capacitor was rusted and bulging... Anyway, I know there are more I haven't watched yet but keep the videos coming! ^_^
I have been in the HVAC industry for three years now and I started out with residential . I remember one of my jobs was for 20,000 .. They were getting two new heat pumps installed in their house right … So before we started working the lead came to us with two dirty filters in his hands and said “yo look at this they only needed new filters “… My other coworkers was like “Damn we should just tell them and go home this not right “ .. My our lead looked at both of us and said “Let’s get to work “ … Smh .. And that was just my first experience with how shady HVAC residential is , but wasn’t my last … Im am now a building engineer and love with I do and don’t feel bad going to work !
Great job! I installed 2 units (3 and 3.5 tons the same way, but with TXV) plus a 1 ton mini split (easier). I have Testo549 with Yellowjacket hoses, vacuum pump and CPS micron gauge, Appion valve core removal tools. Staybrite8 (high vibration, high pressure and refrigeration applications) was a great find for me for the second unit, sped up the process vs brazing with turbo torch. The key is to invest in high quality professional tools/nitrogen tank (for me it was ~$400-500 overall) and then do it slowly. Warranty is not a concern, cause most of the time you will still need to pay for labor (90% of the cost) even if you’re under warranty , the equipment is cheap and available online anytime.
Hey my brother.....great install as usual! I know you are a journeymen HVAC professional, but you still just make it look so easy. I would love to have seen the horizontal coil install but I know it is not always possible in some locations and you can't cater to us DIY'ERS when you are trying to make a living. Would be cool to see this done with some very basic gauges that many of may own and how to read the pressures and better understand the readings of those. Great job! Stay safe out there. Thanks for your continued support of us wanna be HVAC guys.
Totally agreed on SB-8. As a first-timer DIY on Goodman 2 ton condenser, brazing copper pipes was the scariest part. After watching Dave's videos, I am sold and went with SB-8 on my installation. SB-8 is easy to use, just buy extra bags of HVAC fittings and practice them few times till you get the hang of it before you actually doing it on the real installation. As always with anything, the preparation step is the very important - make sure that pipes and fittings are prepared properly, clean, clean... very important. 😀
I’ve DIY installed multiple central A/C and heat pump units and split systems with zero issues. I’m really tired of all the anti-DIY HVAC trade people who think what they do is rocket science. By their way of seeing things they better not try to change the oil on their car if they’re not a schooled factory certified auto technician as they will no doubt destroy the car and suffer severe burns from the hot oil. They just want to protect their often incredibly overpriced trade. Charging $7000 for one person spending half a day to install $1500 worth of hardware is just obscene yet commonplace in their trade.
While you're at it, go ahead and grab you a stethoscope, blood pressure cuff, IR thermometer and start doing medical work. I'm sure you could save money on yourself or your hypocrites in church.
@@USA-GreedyMenOfNoIntegrity An MD requires a medical degree, an HVAC service tech does not. BTW, why don;t you work on designing thousand ton high rise chiller based systems and other high profile HVAC projects. Oh wait, you need a Mechanical Engineering degree for that! LOL, an HVAC tech paralleling his education to that of an MD!
im that guy, its because we have seen homes and families destroyed by people that think they know what they are doing . knowing how to make proper gas connections and, venting , and knowing how to handle refrigerant, can save someones life. i get calls all the time to fix shitty diy jobs
Hey, a great video with lots of good tips and a job well done. I'll offer a safety recommendation regarding high pressure cylinders. You should always turn your regulator back down to zero before opening the high pressure valve. If the low pressure diaphragm side fails, the high pressure can shoot that adjustment knob out at really high velocity. Just saying. 🙂
As someone who works on the distribution side of the HVAC industry, just a heads up to all of the unlicensed DIY guys out there. Read the fine print of the warranty paperwork. They all pretty much state that if the unit is purchased through an online supplier, or installed by an unlicensed individual that the warranty is voided. I have received many calls in the past from homeowners who have a unit that failed, and tell me they need a warranty compressor, coil, TXV, ect... that want to cuss me out when I tell them they have no warranty because they didn't adhere to the manufacturer's specified guidelines. I'm not saying the DIY guys won't or can't do a good job, I'm just trying to let you know that when a problem arises, and eventually one will, that trying to save money in the beginning could cost you dearly in the end.
Thanks for this. Good information for people to know. Generally, if a diyer can have a contractor come and get a replacement part they can have it replaced. But I’ve tried to tell people that Goodman’s only have a 5 year warranty out of the box. Unless registered by a licensed contractor, in which case it would be the full 10 year warranty. Cheers man
When it's time to replace, it would cost less to buy a new whole unit every couple of years ( if necessary) than pay the prices some professionals charge. Warranty be dammed in that case.
That’s great info. While I’m a pilot, I’ve always been fascinated by the trades and do lots of DIY.. Your comments are great. There are some Internet dealers who are telling me that I’d still have a 5 year, even for a self install, because they are an authorized dealer.. Any thoughts on this? Thanks for any help
As a hvac tech great job on the install. Only thing i would suggest is that you need to let your viewers know that they should check with their local laws. Permints may need to be pulled. And its possible that if its not installed by a licensed hvac company insurance can deny any payments if house catches on fire do to improperly installed unit.
I'm all for people making an honest living, but in my area I haven't found a good one yet. Neighbors say the same. I had three outrageous quotes so a few of us with some chops got together and formed a neighborhood group. Now it's actually fun. We never call big companies for annual cleaning and service because when they touch it things start to mysteriously misbehave. And NONE of them did anything but change the filter. Cleaning the outdoor coils? 'we don't have the time for that'. If there were honest word of mouth referrals here I'd consider that but I don't know of any. Thanks for your channel, you would have my business. How is it you don't look miserable and grumpy? I think you would brighten my door if you showed up.
Seriously. Just had a guy out here for a checkup on a 2018 unit & now the unit isn’t working. It was fine before he came I just wanted to keep it in warranty. He said I have a line leak so will need to replace it. I will replace it myself if it comes to it because I am not paying $10-$15k He says oh you’ll get a new furnace and all I said I just got a new furnace in 2018. There is nothing wrong with it why would I replace it? Ridiculous.
Do everything by yourself except for the brazing. That’s the hardest one to get down correctly without any pinhole leaks. You won’t know if you have any until a year later when there is no more charge/pressure. If everything is done correctly then your unit should last you 20-100 years depending on how good you are at maintenance. Good job on saving some money and don’t ever fall for pricey hvac installs if you don’t have to.
In our state Staybrite is not allowed, it is required to braze 15% or better, you may want to put a disclaimer for homeowners to check with their manufacturers IOM and state.
Very green neighborhood for an arid region where swamp coolers work. We had one in a Mojave Desert rental house, but didn't quite suffice when 110 F outside. My 1.5 ton Della minisplit heat pump came with an AC cord of just 16 awg wires (240 VAC). Instead, I ran 12 awg to the cut-off box and previously ran 8 awg stranded from the subpanel to the cut-off, both for the future and because didn't know how little current the compressor would draw (1.5 kW max). My central AC failed, so looking at replacing it. Only need 2 ton or less since the mini was actually cooling my whole house this summer (Central CA, up to 110 F days) and have all Winter to fix 'er. Options keep improving for a smart inverter type w/ duct evaporator. First I heard of this OxBox system.
Very good video and all of the information you provided is spot on ! Some provide way too much info and then other do not supply enough information, but you DIY HVAC Guy , provide the perfect amount of information ........ IMHO ! Thanx for an awesome video !
Values of superheat and subcooling suggest the system is slightly low on refrigerant despite it's new. Please let us know what your follow up readings are. I watched a lot of your videos including famous where vacuum jumped from 500 to 1300 and nevertheless you put refrigerant to the system. This time is way better except you didn't bother to figure out how Fieldpiece manometer works. In general, i enjoy all your videos, thank you for the great work!
Well most of the HVAC system can be done by a tallanted DiY type. But there are parts better left to a proper HVAC contractor, those being the pressure test, vacuum down, and then charge the system properly.
I have a 20-year old Bryant gas furnace. It was installed with the evaporator, lines and power connection outside for a future AC unit. I buddy of mine is installing a new heat pump at his house and he's giving me his 2-yo, 5-ton Blueridge BA16L60P A/C unit. What should I consider/check out in deciding whether this A/C unit will work with the Bryant furnace? I've had HVAC companies out to give me bids on installing A/C and most of them told me that the evaporator couldn't be used, usually without even looking at it, and of course they all want to sell me a new furnace "because that one could fail at any minute!". I don't need the scary sales tactics, I need an honest opinion of what's possible here. Love your videos!
Love your videos. I just got my A/C serviced and the technician said that I would need a new capacitor. He hooked up a voltmeter to the left node and it was about 37%......he said it should be around 40%. The right-side node was about 5%, which he said was good. He said the cost of an installed capacitator would be $375...which seemed very high to me. I took a photo of the part and after he left, I checked on Amazon and saw the part was about $17. My question is ....at 37% does this part have to be replaced? We haven't had any issues to date. I live in the Boston area so the next time we'll use the A/C will probably be in June/July 2025. Thanks
@@tobyrussell7553 Why the huge fuss I always hear about "mismatched equipment"? Sounds like a major over exaggeration if all they need to do is swap a piston with a different sized orifice.
WOW, where are you located, I'll do it for half of that. I'm in south Texas. 9 years in the trade. 9 years of references. Certified installer. These big companies are ridiculous with pricing. The one from last week, lady got quoted 16k from big company. I quoted her 8k. Same warranty and all.
I'm trying to wrap my head around how the Schrader valve installer works without losing any gas or pressure! Lol! I get that it works,I just don't know how 😊
Please at least watch every hvac school video before you try any of this please... this guys vids make it look easy but it isnt....please dont try to diy anything with refrigerant without having full confidence before you start and asking a guy that makes a video isnt the guy to just ask.... you have to be trained and certified to even do this job let alone do it correctly
@amtrakusa1 I understand how a Schrader valve works. What I don't understand is how the Schrader valve installer works. How does it install the Schrader valve under coolant pressure without losing any coolant or pressure?
@Kevin-mp5of ok smart-ass! Yes ,I should have said "refrigerant " ! I guess you needed to feel superior! Obviously, hvac is not my forte. I could troll all your comments looking for a misused word. However, I actually have a really nice life that I'd rather experience than waisting my time correcting other people.
To know just how great this work is you need about 5 years...proper evacuation procedures are about LONG term performance - any hack with a tad of mechanical construction ability can put this together - The real pros warranty and stand behind their years of expertise for a reason and yes there is a cost for that...this is called value.
Sometimes the supply house doesn't have an exact size in stock so you can get a different size and then install the optional "pistons" to make it work.
Hold on a minute you installed a condenser and a air handler in one day! Holy crap you guys are the gurus! Let me Bow down and praise you! I just don't know how you do it! LOL
Every job we do is bid for one day besides three zone or more mini-splits, sometimes those are a day too though. Only job more than a day is adding a lot of return ductwork, but that's often the one long ass day too.
I have a house that has a furnace but no A/C. I always hear about the mini-split options and how that’s the way to go, because they’re easy to install and they’re cheaper or whatever. Is that true? Also what is your opinion on buying an A/C condenser used? Is that a bad idea? Thanks for the video appreciate it!
If you cant wrap your head around how to remove a Schrader val ve without losing any refrigerant, here's your sign. Leave it to someome that actuslly knows. Maybe then you wont get frost bitten or lose the refrigerant.
Hi DIY HVAC Guy, I don't see you charge the new AC unit with the refrigerant. When you charge the new AC, do you turn on the AC system with empty refrigerant in the pipe?
Great video. When your doing a new install of an evaporator coil and condenser is okay just to put the vacuum on the low side, or should you do a vacuum on both low and high side?
My one question is why did you sweat that drier on the tailpiece? If you ever have to open that system up for repairs you would replace the drier correct? How would remove the drier?
Yes. He installed the equipment. Linesets and got them soldered. Next he used Nitrogen to pressurize the line sets. After he proved they were tight. He used the vacuum pump to remove any traces of water. Water and Refrigerate creates an acid. After he proved a tight system again. The very last step is to release the refrigerate into the system.
@@2nickles647 i don't see he charges the system with refrigerant. Did you see it? How did you charge the new AC unit with refrigerant? Do you turn the AC on? I'm not sure if the NEW AC comes with a little bit of refrigerant.
it's interesting comparing this oxbox to Trane's other "cheaper" brand RunTru. The RunTru condensor uses Trane's famous spine fin coil instead of what looks like a microchannel on this oxbox. wonder why??
Dryer vent is a bad idea ! It will need to be cleaned forever. Happened to a relative that had condensing units next to each other ended up replacing both.
I found it very confusing when living in the USA that it is called HVac. It’s only 220 watts. Mine barely worked when it got really hot. But living in a condo, the other owners were not prepared to spend any money to do anything about the almost non-existent insulation of the building.
This guy is brilliant! He has taught me so much. I should be paying him tuition. We are all so lucky to have him doing this for us.

I had three outrageous quotes so a few of us with some chops got together and formed a neighborhood group. Now it's actually fun. We never call big companies for annual cleaning and service because when they touch it things start to mysteriously misbehave. And NONE of them did anything but change the filter. Cleaning the outdoor coils? 'we don't have the time for that'.
If there were honest word of mouth referrals here I'd consider that but I don't know of any.
Thanks for your channel, you would have my business. How is it you don't look miserable and grumpy? I think you would brighten my door if you showed up.
Seriously. Just had a guy out here for a checkup on a 2018 unit & now the unit isn’t working. It was fine before he came I just wanted to keep it in warranty.
He said I have a line leak so will need to replace it. I will replace it myself if it comes to it because I am not paying $10-$15k He says oh you’ll get a new furnace and all I said I just got a new furnace in 2018. There is nothing wrong with it why would I replace it? Ridiculous.
Really enjoy your channel. I'm a home DYI'r and your expertise is appreciated
Big HVAC hates this guy
Do everything by yourself except for the brazing. That’s the hardest one to get down correctly without any pinhole leaks. You won’t know if you have any until a year later when there is no more charge/pressure.
If everything is done correctly then your unit should last you 20-100 years depending on how good you are at maintenance. Good job on saving some money and don’t ever fall for pricey hvac installs if you don’t have to.
Loved watching this whole install. I'm getting smarter. Thanks.
Glad it was helpful!
Wow that was freaking awesome from start to finish you're the man
Nicest crawl space I have ever seen!
In our state Staybrite is not allowed, it is required to braze 15% or better, you may want to put a disclaimer for homeowners to check with their manufacturers IOM and state.
best video i seen on the internet
Very green neighborhood for an arid region where swamp coolers work. We had one in a Mojave Desert rental house, but didn't quite suffice when 110 F outside. My 1.5 ton Della minisplit heat pump came with an AC cord of just 16 awg wires (240 VAC). Instead, I ran 12 awg to the cut-off box and previously ran 8 awg stranded from the subpanel to the cut-off, both for the future and because didn't know how little current the compressor would draw (1.5 kW max). My central AC failed, so looking at replacing it. Only need 2 ton or less since the mini was actually cooling my whole house this summer (Central CA, up to 110 F days) and have all Winter to fix 'er. Options keep improving for a smart inverter type w/ duct evaporator. First I heard of this OxBox system.
Got to install the air dyer on AirQuest too. I put mine next to the evaporator.
Thanks for sharing your experience and knowledge
Dave. Great job! Always learning from you. God Bless!
The reason you put the filter drier next to the coil is to protect the metering device.
Also It will NOT RUST OUT like it would outside !
@@pablogaviria9265You both are wrong
Very good video and all of the information you provided is spot on !
Some provide way too much info and then other do not supply enough information, but you DIY HVAC Guy , provide the perfect amount of information ........ IMHO !
Thanx for an awesome video !
Values of superheat and subcooling suggest the system is slightly low on refrigerant despite it's new. Please let us know what your follow up readings are. I watched a lot of your videos including famous where vacuum jumped from 500 to 1300 and nevertheless you put refrigerant to the system. This time is way better except you didn't bother to figure out how Fieldpiece manometer works. In general, i enjoy all your videos, thank you for the great work!
Thank you for taking the time to show and explain everything. I wonder, do you do installation in the twin cities, MN?
So the unit already comes with the refrigerant in them
Nice looking install Dave from start to finish ... Thx for sharing
Great video 👍🏻 keep it up. Next we need a heat pump installation
Love the Oxbox!
Well most of the HVAC system can be done by a tallanted DiY type. But there are parts better left to a proper HVAC contractor, those being the pressure test, vacuum down, and then charge the system properly.
I have a 20-year old Bryant gas furnace. It was installed with the evaporator, lines and power connection outside for a future AC unit. I buddy of mine is installing a new heat pump at his house and he's giving me his 2-yo, 5-ton Blueridge BA16L60P A/C unit. What should I consider/check out in deciding whether this A/C unit will work with the Bryant furnace? I've had HVAC companies out to give me bids on installing A/C and most of them told me that the evaporator couldn't be used, usually without even looking at it, and of course they all want to sell me a new furnace "because that one could fail at any minute!". I don't need the scary sales tactics, I need an honest opinion of what's possible here. Love your videos!
Great video DIY HVAC Guy! I look forward to your video. Keep up the great work and the great content!
Never use vinyl pipe for drain. Better use cooper 3/8. Vinyl only for connection. Sometimes the mouse like it)) You have very professional tools.
Love your videos. I just got my A/C serviced and the technician said that I would need a new capacitor. He hooked up a voltmeter to the left node and it was about 37%......he said it should be around 40%. The right-side node was about 5%, which he said was good. He said the cost of an installed capacitator would be $375...which seemed very high to me. I took a photo of the part and after he left, I checked on Amazon and saw the part was about $17. My question is ....at 37% does this part have to be replaced? We haven't had any issues to date. I live in the Boston area so the next time we'll use the A/C will probably be in June/July 2025. Thanks
Thank you for showing us how to install an Ace unit
For what reason did you upsize the indoor evaporator to a 2.5 ton while the outdoor condenser is a 2.0 ton?
School me, I am not criticizing, I am not an HVAC professional but have always heard that mismatched equipment doesn't work right.
Just have to change piston
@@tobyrussell7553 That's it?
@@tobyrussell7553 Why the huge fuss I always hear about "mismatched equipment"? Sounds like a major over exaggeration if all they need to do is swap a piston with a different sized orifice.
@GlobalistGuillotine can upsize or downsize to an extent like .5 ton or 1ton max
I’m checking this out now . I messed up when I went fixing my unit . 😂
Dude, you Re the best!!
My gf is going to pay a company $20K to replace a furnace and condensing unit.....omg , I'm trying to save her!!
WOW, where are you located, I'll do it for half of that. I'm in south Texas. 9 years in the trade. 9 years of references. Certified installer. These big companies are ridiculous with pricing. The one from last week, lady got quoted 16k from big company. I quoted her 8k. Same warranty and all.
I'm trying to wrap my head around how the Schrader valve installer works without losing any gas or pressure! Lol! I get that it works,I just don't know how 😊
It's just a round spring loaded valve with a sealing gasket
Please at least watch every hvac school video before you try any of this please... this guys vids make it look easy but it isnt....please dont try to diy anything with refrigerant without having full confidence before you start and asking a guy that makes a video isnt the guy to just ask.... you have to be trained and certified to even do this job let alone do it correctly
Amtrakusa1 your giving bad info to a person that has no idea of what they are doing
@amtrakusa1 I understand how a Schrader valve works. What I don't understand is how the Schrader valve installer works. How does it install the Schrader valve under coolant pressure without losing any coolant or pressure?
@Kevin-mp5of ok smart-ass! Yes ,I should have said "refrigerant " ! I guess you needed to feel superior! Obviously, hvac is not my forte. I could troll all your comments looking for a misused word. However, I actually have a really nice life that I'd rather experience than waisting my time correcting other people.
YOU NEED TO DO ONE ON QUICK REPLACEMENT OF ALREADY EXISTING UNIT, SWAPPING OUT OLD ONE AND PUTTING IN NEW ONE
IF ITS POSSIBLE
To know just how great this work is you need about 5 years...proper evacuation procedures are about LONG term performance - any hack with a tad of mechanical construction ability can put this together - The real pros warranty and stand behind their years of expertise for a reason and yes there is a cost for that...this is called value.
Great Video. Love watching your work.
Fantastic video, thanks
I know good work when I see it you would make a killing here in Houston,Tx.
should have pulled schrader core so that they dont melt due to brazing by valves. great video!
This is so thorough
Hello your videos are great and helpful ,do you have any video on how to do duck work from scratch my house was having window unit thanks.
I don’t. I hate ductwork 🤣 sorry man. I will be redoing the supply ducting in my home soon. So stay tuned for that :)
R-410A is a azeotropic blend. HIGH pressures in a soft sau
Soft solder on R-410A 😅😅😅😅 crazy.
Good video thanks
Why would you choose to upsize the evap. coil? Is there a benefit?
Sometimes the supply house doesn't have an exact size in stock so you can get a different size and then install the optional "pistons" to make it work.
@@anonymousbaros4424as long as it's no greater or less than half a ton difference.
Rock on buddy.
Hold on a minute you installed a condenser and a air handler in one day! Holy crap you guys are the gurus! Let me Bow down and praise you! I just don't know how you do it! LOL
Thanks man. It was all Terry 🤪
Every job we do is bid for one day besides three zone or more mini-splits, sometimes those are a day too though. Only job more than a day is adding a lot of return ductwork, but that's often the one long ass day too.
Awesome video! Could you please tell me where do you buy copper your line set ? Thank you.
You should put a some sort catch can when releasing the nitrogen to see if something actually does come out of the line.
superb content.!! thank you
Like to put silicone to seal off the front panel of the coil. This makes it easier to access the coil in the future.
Another great video, thanks for sharing.
Will you someday post a tutorial of how to replace a Carrier heat pump with a compatible replacement?
Great video
What do you recommend doing for a refrigerant leak in your thermos with out replacing it
My current AC condenser is over 20 years old, getting on its last leg. I heard the newer AC units are more energy efficient as well?
For my experience, if u buy off from online without license, there is no manufacturer warranty on that. Finger cross it works well.
I offer that service at Patreon.com/diyhvacguy we can register your equipment for a flat rate of $100 Then it will be covered for the full 10 years 👍🏼
Staybright 8. Do you not need nitrogen with this solder?
Im no professional, but i was taught to purge with nitrogen, then braze with silver solder.
So awesome thank you.
Did you notify the homeowner that not insulating the duct under the house could cause sweating and that will draw termites.
We live in utah, they simply don’t sweat here 👍🏼 but I could see that in a more humid state
I have a house that has a furnace but no A/C. I always hear about the mini-split options and how that’s the way to go, because they’re easy to install and they’re cheaper or whatever. Is that true? Also what is your opinion on buying an A/C condenser used? Is that a bad idea? Thanks for the video appreciate it!
If you cant wrap your head around how to remove a Schrader val ve without losing any refrigerant, here's your sign. Leave it to someome that actuslly knows. Maybe then you wont get frost bitten or lose the refrigerant.
Hi DIY HVAC Guy, I don't see you charge the new AC unit with the refrigerant. When you charge the new AC, do you turn on the AC system with empty refrigerant in the pipe?
Great video. When your doing a new install of an evaporator coil and condenser is okay just to put the vacuum on the low side, or should you do a vacuum on both low and high side?
yes, i would do it.
lmao. Not me being totally confident I could install an A/C unit on my own until I saw this video.
17:29 My son & I use a bending spring.
It seems like Goodman and American standard are the brands. Is Oxbox any good?
My one question is why did you sweat that drier on the tailpiece? If you ever have to open that system up for repairs you would replace the drier correct? How would remove the drier?
So the units come with the refrigerant already in it
Yes. He installed the equipment. Linesets and got them soldered.
Next he used Nitrogen to pressurize the line sets.
After he proved they were tight. He used the vacuum pump to remove any traces of water. Water and Refrigerate creates an acid.
After he proved a tight system again.
The very last step is to release the refrigerate into the system.
@@2nickles647 i don't see he charges the system with refrigerant. Did you see it? How did you charge the new AC unit with refrigerant? Do you turn the AC on? I'm not sure if the NEW AC comes with a little bit of refrigerant.
Hi, can you do a video on how to lift a vertical stack airbox to replace the boxed evap under it? Tks
it's interesting comparing this oxbox to Trane's other "cheaper" brand RunTru. The RunTru condensor uses Trane's famous spine fin coil instead of what looks like a microchannel on this oxbox. wonder why??
Great great video, thank you. Stay-Brite 8 is awesome
great job but when you soldering try not to let the flame hit the solder
So you're soldering? not bracing right? I thought adding flux could harm the system....just a little confuse.
That’s not a Trane “rebranded” unit. It’s just made by the parent company that owns Trane. How do I know ? I work for Trane.
Dryer vent is a bad idea ! It will need to be cleaned forever. Happened to a relative that had condensing units next to each other ended up replacing both.
Should we assume that ductwork in the crawl space is insulated? The OxBox is an interesting design.
Why would you braze vs doing the stay brite method?? Thank you
This was awesome!!! Does the outdot breaker serve as your disconnect?
Yesir. As long as it’s within 6ft from the unit. 👍🏼
Thank you for sharing your experience and knowledge, but I’d still hire you (if you were local) just the same.
Great video! Do you ever braze anymore?
I found it very confusing when living in the USA that it is called HVac. It’s only 220 watts. Mine barely worked when it got really hot. But living in a condo, the other owners were not prepared to spend any money to do anything about the almost non-existent insulation of the building.
