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
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.
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 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.
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'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.
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.
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. 🙂
I just replaced my old furnace and AC system after I installed it the new system is working fine,.. It was a little bit harder than how it looks in the videos but I was able to do it, thanks so much for your videos I saved a lot of $$$$
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. 😀
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.
@@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.
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.
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.
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.
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 !
i mean i like your trying to teach people the trade been in it for over 10 years but ive also seen a lot of landlords or people try to do their own repairs and mess it up badly in my opinion its best to find a trusted company or private contractor, plus the cost of the tools to actually install a system can very easily add a couple thousand.
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!
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.
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
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?
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.
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.
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?
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.
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
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!
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?
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.
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!
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.
Is that soft solder ok for 410 A or is it recommended by manufacture we usually use silver solder and the metal ducts are not insulated, I understand for heating since it was an existing system but now that you have added cooling are they not any code issues for not insulating metal ducts. My guess is you are in a northern climate, Down here in Texas it is a requirement to use a minimum of R-8 duct insulation on any ducts outside the building envelope which is 2 inch thick.
If you dont know then dont try...!! not trying to be offensive but this is a trade people go to school for and have to pass to be certified to do such a job... this job is not a diy job and he should tell you only professionally trained and qualified people should be doing this trade.... some of these videos give off an i can do this job view but im telling you by someone that does this every day that it is not, these are just slightly informative videos with alot left out and alot more to learn....
@@esbonwordenjr6069 I agree it's super complicated for the average joe, and prob most people who think they can do it actually can't. But there is a few trained in other fields that could do this fine. But even if they could handle it, they don't do it enough and have the experience to prob be as proficient as you or those in your trade.
Thank you for the responses. I think my question was more simple. Can a condenser unit, say a 2 ton, use either a 2 ton evap with an expansion valve or evaporator with fixed orifice. In other words, Can a condensor unit accommodate both coil types depending on the application. Thank you
Yes all a fixed orfice or txv does is create the pressure drop and make the liquid to start the phase change.... all they do is make the liquid turn into a vapor like when u put your thumb over the end of a hose and you get the mist from it.... a vapor/ mist state is the best form to pull heat out that is why over charged system dont work cuz not only do u flood your compressor but u flood your evap coil with liquid instead of vapor and in liquid form you cant extract heat..... but yes you need a pressure drop of somesort weather it be an orfice or txv.... you can take a txv out and replace with an orfice or vise versa unless u have an exv which is controlled by a circuit board and sensors because you may have a modulating unit so the superheat will always be modulating according to temp and pressure
hey dave I got a question about some hack that took a pair of channel locks and crimped the low side coupling around the old line set in a apartment unit on a roof he was replacing a goodman condenser it seemed like the new unit was like 1 inch and line set was 3/4 or 7/8 and brazed the crap out and said something like 15 percent the braze would be filled in maybe you can add this to you video hope to hear from you!
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.
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.

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
Wow that was freaking awesome from start to finish you're the man
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.
So the unit already comes with the refrigerant in them
best video i seen on the internet
Really enjoy your channel. I'm a home DYI'r and your expertise is appreciated
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.
Nicest crawl space I have ever seen!
Awesome video! Could you please tell me where do you buy copper your line set ? Thank you.
Nice looking install Dave from start to finish ... Thx for sharing
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.
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 !
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
i mean i like your trying to teach people the trade been in it for over 10 years but ive also seen a lot of landlords or people try to do their own repairs and mess it up badly in my opinion its best to find a trusted company or private contractor, plus the cost of the tools to actually install a system can very easily add a couple thousand.
When did you add the coolant after the vacuum?
Loved watching this whole install. I'm getting smarter. Thanks.
Glad it was helpful!
What do you recommend doing for a refrigerant leak in your thermos with out replacing it
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!
Dave. Great job! Always learning from you. God Bless!
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.
Thanks for sharing your experience and knowledge
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
@@boeing757pilotI’m a dentist and I enjoy installing mini splits and servicing my units.
@@abelaguilar8137 That's great to hear! It is fun.
Great video DIY HVAC Guy! I look forward to your video. Keep up the great work and the great content!
Great video 👍🏻 keep it up. Next we need a heat pump installation
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?
Hi, can you do a video on how to lift a vertical stack airbox to replace the boxed evap under it? Tks
R-410A is a azeotropic blend. HIGH pressures in a soft sau
Soft solder on R-410A 😅😅😅😅 crazy.
should have pulled schrader core so that they dont melt due to brazing by valves. great video!
Where can buy the coil and the condensing unite, every store around me won't sell them to me with out a license
Thank you for showing us how to install an Ace unit
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.
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.
Why would you braze vs doing the stay brite method?? Thank you
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.
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.
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?
Can i install one condenser for 2 furnaces???
never seen silver soft solder? are you sure that is good for refer lines?
I’m checking this out now . I messed up when I went fixing my unit . 😂
You should put a some sort catch can when releasing the nitrogen to see if something actually does come out of the line.
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.
Do we need to get a separate line set? I searched same model and Im not sure if I should add line set or not
Love the Oxbox!
YOU NEED TO DO ONE ON QUICK REPLACEMENT OF ALREADY EXISTING UNIT, SWAPPING OUT OLD ONE AND PUTTING IN NEW ONE
IF ITS POSSIBLE
17:29 My son & I use a bending spring.
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
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.
I know good work when I see it you would make a killing here in Houston,Tx.
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!
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?
Big HVAC hates this guy
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.
Where did you 14.7 atmospheric pressure when inputting it in the app? 27:00
Just teaching myself, appreciate it!
Just Google your atmospheric pressure near you. It’s 14.7 at sea level
Your local airport will have the atmospheric pressure readings 😊
Where do I get that umbrella set up.
So where does one get a line set?
Fantastic video, thanks
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!
Great Video. Love watching your work.
I’m in an older house that has a 100 amp as the main breaker for the house. Would I have to up that to a 200 to install this?
Depends on the size. If it’s smaller like a 20 amp breaker, (1.5-2 ton) then you could probably get away with it.
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.
Will you someday post a tutorial of how to replace a Carrier heat pump with a compatible replacement?
Is that soft solder ok for 410 A or is it recommended by manufacture we usually use silver solder and the metal ducts are not insulated, I understand for heating since it was an existing system but now that you have added cooling are they not any code issues for not insulating metal ducts. My guess is you are in a northern climate, Down here in Texas it is a requirement to use a minimum of R-8 duct insulation on any ducts outside the building envelope which is 2 inch thick.
It seems like Goodman and American standard are the brands. Is Oxbox any good?
Do you have to add oil because on vehicles we do? Just wondering. Do you have a video on adding or changing the oil? Thanks
Great video. Does it matter if you use an evaporator with a txv or fixed orifice with the same condensor or is it condensor specific? Thank you!
If you dont know then dont try...!! not trying to be offensive but this is a trade people go to school for and have to pass to be certified to do such a job... this job is not a diy job and he should tell you only professionally trained and qualified people should be doing this trade.... some of these videos give off an i can do this job view but im telling you by someone that does this every day that it is not, these are just slightly informative videos with alot left out and alot more to learn....
@@esbonwordenjr6069 I agree it's super complicated for the average joe, and prob most people who think they can do it actually can't. But there is a few trained in other fields that could do this fine. But even if they could handle it, they don't do it enough and have the experience to prob be as proficient as you or those in your trade.
Thank you for the responses. I think my question was more simple. Can a condenser unit, say a 2 ton, use either a 2 ton evap with an expansion valve or evaporator with fixed orifice. In other words, Can a condensor unit accommodate both coil types depending on the application. Thank you
Yes all a fixed orfice or txv does is create the pressure drop and make the liquid to start the phase change.... all they do is make the liquid turn into a vapor like when u put your thumb over the end of a hose and you get the mist from it.... a vapor/ mist state is the best form to pull heat out that is why over charged system dont work cuz not only do u flood your compressor but u flood your evap coil with liquid instead of vapor and in liquid form you cant extract heat..... but yes you need a pressure drop of somesort weather it be an orfice or txv.... you can take a txv out and replace with an orfice or vise versa unless u have an exv which is controlled by a circuit board and sensors because you may have a modulating unit so the superheat will always be modulating according to temp and pressure
A question if I may. Why does the label on the condensing unit state Federal Law allows this unit to be installed only in certain states?
U didn’t take the shrader cores out while brazing?
Nope, not needed with Staybrite 8 👍🏼
So you're soldering? not bracing right? I thought adding flux could harm the system....just a little confuse.
This is so thorough
Rock on buddy.
hey dave I got a question about some hack that took a pair of channel locks and crimped the low side coupling around the old line set in a apartment unit on a roof he was replacing a goodman condenser it seemed like the new unit was like 1 inch and line set was 3/4 or 7/8 and brazed the crap out and said something like 15 percent the braze would be filled in maybe you can add this to you video hope to hear from you!
Where did you get the Oxbox?
A jackleg distributor.
Can you use Staybrite 8 on R134a????
Good video thanks
Great video! Do you ever braze anymore?
This was awesome!!! Does the outdot breaker serve as your disconnect?
Yesir. As long as it’s within 6ft from the unit. 👍🏼
