Awesome, glad you found it helpful. I have another full install posting this Friday. Check it out! Let me know if there is certain things you’d like to see on this channel too! Cheers
Just finished watching Part 1, which I feel I can do. Part 2 is in my attic and huge. I'm not sure I could do any of that myself, unfortunately. Great videos and really takes the unknown out of the equation.
That's one of the great benefits of RUclips, you can see it done & choose when to step out & let the pro handle it. Whether it's too much skill or too much labor required. After I rebuilt my carburetor for the third time, I figured I'd leave the mechanic work to them guys & focus on what I'm good @. Pay him for his, get paid for mine, & watch the economy work! Lol
I am no plumber but I don't see a drip leg on their gas line..... that would def fail inspection and when/if they go to sell their house, they'll have to remediate that! In many places nowdays, you don't need one on your dryer or even stove (as many newer model's have features built in to eliminate debris in the gas lines) but a minimum of a 3" sediment trap must be installed for all gas furnaces and water heaters. Awesome HVAC videos by the way! ^_^
I've taken a few HVAC classes and did some troubleshooting repair work on and off throughout the years. Never had the confidence to do an install on my own and that has stopped me from getting into the business. So much so that I decided to learn how to drive a truck and have been doing that for the past 15-plus years. You have really helped me out!! I have been waiting for a full install video and this is so informative from start to finish and has saved me from going back to take more classes and wasting more money on what I already know. This shows me I was making it harder than it was. THANKS, MAN!!! SUBSCRIBED!!! SIGNED, YOUR NEW BEST FRIEND!!

@@diyhvacguy so I replaced my inside unit a few years back and it’s on the old Freon I need to replace my outside unit now and after watching part one I am pretty sure I can do that but my inside unit needs a new nozzle or something do you have a video of swapping that out
you know i have seen a lot of videos and some are very good. i really enjoyed watching your videos, you certainly has what it takes to be an instructor................you have clear thoughts and clear explanations. Thanks b
I stumbled on your videos and watched out of curiousity. I just had an entire unit (30 yrs old) replaced about 8 months ago, and will be paying for it for awhile. I would have LOVED to have replaced mine by myself. Have a EPA cert for autos (took 20 min of study to get). Used to get refrigerant in 30lb bottles, but no longer can because I'm not affiliated with a shop. This video series is AWESOME because it shows in simple steps how anybody can do this themselves, and some of the tools you used were really nice to see (and I'm buying some - thanks for the links/tips!)
You sir have been a godsend for me. I’m a master plumber and I can Silver solder and do all the grunt work easily but I just need clear directions. You have literally saved me thousands and thousands of dollars I’m going to put in a goodman system to replace my old carrier system.
R22 = $70/lb, tell that to my HVAC guy who wants to charge me in excess of $200/lb for it. Idk what's going on with the trades these days, but price gouging is an understatement.
Appears you can order the stuff from online sites that is a Mexican brand where its still legal to manufacture. I was giving it serious considerations after calling about 2 dozen local HVAC companies and NONE of them had real R22 to top off my system. ALL of them wanted to mix refrigerants, which is both illegal and from what I've read will kill your compressor. Real shady people out there. Most of them were trying to pass off the compatible stuff as R22, until I really pressed them if it was real R22 and not the replacement stuff. None of them offered to pump down my system and replace it with the replacement stuff, which the only real option they should have offered if they didn't carry R22. I've read that many of these places are purposely not carrying (probably all in cahoots with each other) to force the customer to upgrade, and perhaps score a huge payday for them. Perhaps another reason they're doing mixing is secretly hoping it does kill off your still running R22 system so that you'll be forced to buy a new unit, with either R410A or perhaps even the newer R454B stuff (if you can find any actual systems in Jul 2024). All I know is dealing with these companies (in S. FL) can be exhausting and immensely frustrating. Finding an honest Joe in the bunch is next to impossible sometimes.
@@dominicfaillo6547 That is covered already in the base house visit fee and/or per hour time & labor estimate. I believe he was talking about the uncharge for the refrigerant over and about that. And yes, the public can also purchase refrigerant online and have it delivered. We just have to check a box that says it is being purchased for someone else (with an EPA license) to use.
Ability Refrigerants has R22 for $55/lb for a 2lb bottle. you can get it for $40/lb if you buy in larger quantities. Their prices are cheaper than the local distributor.

That furnace you are removing looks about 20 years newer than my 30yr old Carrier Weathermaker. When i saw that kink in the csst gas line I immediately knew it was installed by a hack.
I have 1996 tempstar AC. I want to replace furnace and AC but if I go to r410 what would i have to do to lineset that has r22. everything still works good.
Wow, thanks for sharing. I am not sure if I want to take this on myself. I just got quoted for over a 20K job for upgrading the HVAC system with heat pump ones. Damn, that's a huge price to replace my perfectly fine working gas system. My AC is still cold too. Even with rebates, it still doesn't' t make financial sense. I wonder why you are replacing this unit in the video? It seems like it's still works?
Great video! Two questions, can I replace only my condenser unit without replacing the piece in the attic? My old condenser still using R32. The new one would use 410A would that affect the replacement in any way?
Awesome video. You are doing a great service. That being said..... you lost me at part two.....that is beyond my ability lol. But this is still incredibly helpful as it gives me more of an idea of what technicians are doing when I have to call them.
I'm a little late to the show but glad I stumbled on to these videos. Question, as your camera took a break during the coil install, why did you struggle to install the coil and all associated parts together instead of removing the coil first to save some weight? I'm about 40+ years older than you and always look for the less strenuous way of accomplishing something. My 3 ton heat pump HVAC is acting up at a mere 17 years old, sometimes the coil freezes, sometimes the outside fan won't shut off unless I flip the breaker. New run capacitor that I keep here doesn't make a difference so I am taking a RUclips crash course on troubleshooting and repair while it still works. Thanks for providing information in easily (mostly) understood language, not too much HVAC jargon that the rest of us don't use on a daily basis. I subscribed so I can go through your library and try to match my units symptoms with a solution.
I think my furnace is on top of my ac. is this going to make the job much more difficult? it's all in a mechanical closet in a ranch-style home. thanks for these videos brother, wealth of knowledge here
At 21:42 can you tell us what tool/bit you use to expand the pipe opening (swage) ? Edit: nevermind, I found it in the description. Leaving this here for others 😀
Yesir. I left those in the description but here they are :) they are one of the best purchases I’ve ever made for copper pipe fitting! www.amazon.com/dp/B0933BW9QN/ref=cm_sw_r_as_gl_api_gl_i_F8NVH141MAR4W7FD3MD7?_encoding=UTF8&psc=1&linkCode=ml2&tag=wasatchmoto0d-20
I was with you installing the AC unit on the outside of the house but when you got up and the attic to replace the coil I said oh no That's a little too much for me however when I do go purchase my new HVAC unit for my home which is about $1,480 ft² one story home attic no basement what would be a ballpark figure I should pay to have it installed by a HVAC company that way I know I'm not getting overcharged???
I put my own ac in our 1sy house... Just left my # at web supply for someone looking to vacuum pump ystem and and let in coolant... I had done the rubber spacer on top of our cool to duct work.
Is it possible to replace ONLY the outside condenser unit and not the inside? I have a UNICO high velocity AC in the attic that works fine. It's just the outside unit that may need replacement. Thanks.
@@anthonynguyen8031 So I found out that both external condenser and internal fins need to use the same refrigerant. So the older is R22 technology, newer is R-410A and uses synthetic oil and higher pressure. So like me, you'd need to find a R22 condenser unit (most likely used) that would match up with the fins that are in the unit itself. You can find some used R22 condensers with the freon already in them, so whomever hooks it up for you wouldnt need to recharge the entire system with new freon, rather "release" the R22 that's already in it. All that is above my pay grade.
What were those coils that were in the area below the evap coil? I'm adding ac to a house that didn't have it before, I have the unit and evap coil but whatever was in that area below the evap coils here I have no idea what that was
I was unsure if the job was finished, after connecting the copper lines do you need to recharge the system with refrigerant? Or is there plenty in the new unit?
Also seems much easier nowadays for anyone to buy the parts needed. ONLINE! Before you needed an account at a Johnstone or something. Even FB market place! Ebay, etc...
I've done so much DIY on my old Goodman unit, from 1998, that I feel like I could pretty easily do everything in the video, up to and including buying the gauges and getting an EPA universal license just to legally buy and put in the refrigerant. The real issue for me is the whole permitting process. Where I am, in S FL, the consider an AC replacement as a "construction project" so they can make even more money on permitting fees. So if you don't pull a permit that you are running afoul of the law. And you will also decrease the resale value of the home if they cannot find a record in the permitting office that the system was both permitted and professionally installed by a licensed contractor. And if you do pull a permit, you will then be subjected to inspection. Which is even more $$$. All of this makes it really hard for the advanced and handy DIY homeowner to do the changeout themselves. Which I guess is the point. And forcing them to pay thousand extra to do something they could have done with the proper research and time as a hobby effort.
Check to see if there is an exception for homeowner's to install their own equipment with a permit / inspection. That was my case for replacing my electrical panel in Kansas.
I’ve done that before. It’s mega easy. You’d just pick back up in part 3 which will post tomorrow morning. Braze the new unit in, pressure test, pull the vacuum, while that’s running, hook up your electrical. Then once the vacuum is pulled open the valves on the new unit which lets the freon into the whole system. Pre-charged up to 35ft. Then fire it up!! :)
Excellent info, but at 15:00 I've never heard of a TVX before and am not sure how decide if to use "just a piston" or not. It might be a good idea to do another video series that shows how to plan out what an AC system needs because without the planning the installation information can't really be used effectively.
Noted! I’m in the middle of filming a full install with a txv so I will explain that! Thanks for the tip. The txv will allow your system to run more efficiently, allowing the proper amount of freon in the system depending on the demand. I personally prefer the piston as there is just less to go wrong, but the txvs are used in a lot of systems and will lower your monthly electric bill.
I have those cutters the only thing I don't like about them wish they had a way were you can lock it to the Drill since some times you don't have a free hand to hold on to both but I do like them they work great. Also my coil is at the bottom of my unite since I have a down draft,
During the installation of the evaporator coil I noticed that the furnace brand at the bottom is Amana. My question is : Isn't the evaporator coil need to be compatible with the furnace and the blower fan in anyway? Could you please explain. Thanks
Brand does not matter. They all function the same. The size is what matters. Just make sure to match the ac tonnage and you can leave the furnace if it is relatively new. Cheers
Great video!! My current old evaporator coil is 5 ton horizontal with top connection. Can I change to Goodman CHPF4860D6 evaporator coil with side connection? If yes, is it easy to switch from top connection to side connection? Thank you.
Thanks for the video. Im getting ready to have a Trane XR14 2.5 tone outdooe unit installed in ny 1100 sq ft home in SouthWest Missouri. Whats your take on tge XR14 Trane units these days? Im replacing a 25yr old 10 seer 2.5 tone AC that still works but looking for more effency from my electric company. Cost is $5500 installed. Any tips I should watch out for during the install?
Im looking at buying my new indoor/outdoor unit. it looks like there is a option for a/c only but also heat pump/furnace...how can i tell what system i currently have? I'm also going up a half ton due to a add on to my house.
A heat pump will have a reversing valve. If you look down in the condenser, it looks like a cylinder with two perpendicular pipes coming off of it and some wires going to it. If you need for your help, seeing what you have, feel free to sign up for our Patreon membership at Patreon.com/DIYHVACGuy. Cheers.
So I need to replace my mother-in-laws ac unit, and she is on a limited budget. How do you buy one of these units? I went to ac dealers and said you need to be a dealer to buy a unit.
You don’t have to, as long as the coil is 410a. If it’s r22 you can’t run a 410a condenser. The r22 coils are not designed for the higher pressures unless stated on the coil itself.
Does the evaporator coil have to be replaced or can we stop after your part 1 video if our ac unit is working fine but we just want to replace with a more efficient unit?
Totally. I should make a video answering that question. I’ve replaced a condenser because the compressor locked up, and left the Evap coil and it ran for many more years. It all depends on if the compressor has a burnout or not. You’ll know if it has burnout immediately after opening the lines. It’s the worst burnt smell you’ll ever smell.
@@diyhvacguy that was the answer to the question i was looking for as i scrolled here. Perhaps add that to the description of the video also. This video series is awesome. Thankyou for taking the time to put it all together.
I love this series, thank you. Is there a better return air grill out there? My current grill resonates when the unit is running which is quite annoying.
What if that suction line was smaller due to the older unit specs, and the new 410a Coil calls for a 7/8 suction line, what would you do??? Run a new line set or keep the existing one and use a reducer?
I’d run a new lineset. If it’s 3/4 lineset you could do a reducer, but I did one not too long ago that had 5/8 suction and the new one called for 7/8 so we had to pull a new line set
If your existing system is r22 only then yes, if it’s labeled r22 or 410a then you can more then likely just replace the condenser, but the r22 coils will not work with the higher pressure of 410a
Because the condensing unit dictates what orifice is needed. That’s why all new condensing units come with one stuck to the side of it. And yes this unit is using the fixed orifice. Much simpler and less to go wrong.
So basically what you are saying is rather than find the leak you just opted to sell a new unit? Compressors usually get noisy when they're low on refrigerant and oil. I would have located the leak and given the customer the option of repairing or replacing. I'm sure you did that along with recovering the freon with a reclaiming machine.
Hey, so you can’t go up a whole ton, you will have issues. I’d recommend replacing with the same size as what is there. So we offer a remote assistance service over at Patreon.com/diyhvacguy where we will help you find equipment and get it replaced. If that’s something you’re interested in, check it out! We have helped tons of people do their own replacement. Cheers
I have a 20-year-old system that I want to change. My system uses r22, but I noticed a lot of newer systems use 410A. My questions are. Why didn't you completely change out the air handler? And if i just replace the evaporator coil like you did in this video, will it make it an issue with running 410a in an air handler that was originally r22? I'm just wondering if I should make sure the blower motor is replaced also and not just the evaporator coil.
The blower has nothing to do with the coil. It’s completely separate. If it were me I’d replace everything. The customer just didn’t want to replace the furnace that’s why we only replaced the coil and condensing unit. No harm is done if you just replace the coil and condenser. If you need help finding the right system, feel free to email me and I’d be happy to help. Stojicrepair@gmail.com
@@diyhvacguy I've seen videos were HVAC technicians added freon to compensate for the long freon lines. Is that not a necessary step or is it recommended?
@@That1GuyOnRUclips if it’s longer then 20’ then yes you may need to add some. But most jobs are under 20 ft. If you did a system yourself you can always have a technician come and top it off and check the superheat and subcooling.
Yes, it’s very hard to flush the Evap coil so my recommendation would be replacing. You can however flush the lineset and be ok. A burnout is pretty uncommon though.
Is it possible to install a new unit directly up against the wall of the house? We have a small patio and the old unit is smack dab in the middle so we want to install a new one right up against the house. Even better, wish they made wall hanging units!
Really appreciate guys like this not afraid of sharing knowledge.
These videos are not just for DIYers, it is also for hvac students (my case) great video! 😃👍

Respect to you everyone that works in the HVAC field. This is not only a technically challenging job but a physical one as well.
If this is "technically challenging" the HVAC technicians must have a room temperature IQ.
Just finished watching Part 1, which I feel I can do. Part 2 is in my attic and huge. I'm not sure I could do any of that myself, unfortunately. Great videos and really takes the unknown out of the equation.
don’t do it man leave it to professionals cause once it stops running right you’ll just pay double.

Good DIY video to learn from you how to replace an AC unit, however we do not have to go to part 2 if Evap coil still ok ?
Right, just make sure your Evap coil is ok for r22 or 410a because some are not rated for the higher pressure of 410a
You do a great job and have made things easy in the furnace and ac world for me. I really appreciate you.

You can find some used R22 condensers with the freon already in them, so whomever hooks it up for you wouldnt need to recharge the entire system with new freon, rather "release" the R22 that's already in it. All that is above my pay grade.
THAT SEALANT WORKS GREAT ONCE IT DRYS ITS VERY HARD TO TAKE APART SOLID JOB
Are you a professional tech? You don’t sound very smart!!!!
What were those coils that were in the area below the evap coil? I'm adding ac to a house that didn't have it before, I have the unit and evap coil but whatever was in that area below the evap coils here I have no idea what that was
I was unsure if the job was finished, after connecting the copper lines do you need to recharge the system with refrigerant? Or is there plenty in the new unit?
Hi, could you share the tools name that you used to cut the duct? Thanks in advance
Great videos bud
im a new subscriber
Going to do mine in the spring. I have NO ROOM at all like you do though. Removing the duct work is going to be a PITA.
If you need any help feel free to email me at diyhvacguy@gmail.com Cheers
I should have done it last spring. Condensing units and A coils went up in $$$ about 30%!!! 😳
Also seems much easier nowadays for anyone to buy the parts needed. ONLINE! Before you needed an account at a Johnstone or something. Even FB market place! Ebay, etc...
I've done so much DIY on my old Goodman unit, from 1998, that I feel like I could pretty easily do everything in the video, up to and including buying the gauges and getting an EPA universal license just to legally buy and put in the refrigerant. The real issue for me is the whole permitting process. Where I am, in S FL, the consider an AC replacement as a "construction project" so they can make even more money on permitting fees. So if you don't pull a permit that you are running afoul of the law. And you will also decrease the resale value of the home if they cannot find a record in the permitting office that the system was both permitted and professionally installed by a licensed contractor. And if you do pull a permit, you will then be subjected to inspection. Which is even more $$$. All of this makes it really hard for the advanced and handy DIY homeowner to do the changeout themselves. Which I guess is the point. And forcing them to pay thousand extra to do something they could have done with the proper research and time as a hobby effort.
Check to see if there is an exception for homeowner's to install their own equipment with a permit / inspection. That was my case for replacing my electrical panel in Kansas.
Do you have to replace the inside unit if only the outside unit is bad, or can just the outside unit be replaced
Can you leave the old inside coil if it aint leaking?
How did you that evap coil was going to fit on the furnace? Universal fitting??
Looking good sir! What if you just want to replace condenser unit and use the old a coil?
I’ve done that before. It’s mega easy. You’d just pick back up in part 3 which will post tomorrow morning. Braze the new unit in, pressure test, pull the vacuum, while that’s running, hook up your electrical. Then once the vacuum is pulled open the valves on the new unit which lets the freon into the whole system. Pre-charged up to 35ft. Then fire it up!! :)
@@diyhvacguy do I need to change the valve or anything on a coil?
@@hitekrednek66probably a good idea while the system is opened up. Txv’s are not too bad to swap out. I’ll do a video on that at some point :)
Excellent info, but at 15:00 I've never heard of a TVX before and am not sure how decide if to use "just a piston" or not. It might be a good idea to do another video series that shows how to plan out what an AC system needs because without the planning the installation information can't really be used effectively.
Noted! I’m in the middle of filming a full install with a txv so I will explain that! Thanks for the tip. The txv will allow your system to run more efficiently, allowing the proper amount of freon in the system depending on the demand. I personally prefer the piston as there is just less to go wrong, but the txvs are used in a lot of systems and will lower your monthly electric bill.
Thermal Expansion Valve just need to know how to adjust.
Great video. The furnace is old and probably should have been replaced too.
Agreed but that’s what the customer wanted
I have those cutters the only thing I don't like about them wish they had a way were you can lock it to the Drill since some times you don't have a free hand to hold on to both but I do like them they work great. Also my coil is at the bottom of my unite since I have a down draft,
Could you have taken the coil out before setting the box un😢the duct work?
During the installation of the evaporator coil I noticed that the furnace brand at the bottom is Amana. My question is : Isn't the evaporator coil need to be compatible with the furnace and the blower fan in anyway? Could you please explain. Thanks
Brand does not matter. They all function the same. The size is what matters. Just make sure to match the ac tonnage and you can leave the furnace if it is relatively new. Cheers
Great video!! My current old evaporator coil is 5 ton horizontal with top connection. Can I change to Goodman CHPF4860D6 evaporator coil with side connection? If yes, is it easy to switch from top connection to side connection? Thank you.
do you have video how to install txv valve?
How about a roof top ac on a condo do you have a video.
Awesome video, can you do one how to replace a Goodman 100,000 BTU furnace horizontal in the attic, and where to purchase a Goodman system
were you trying to increase the heating and cooling so you were replacing it? just want to know
There was a leak at the Evap coil so we replaced the coil and condenser
Thanks for the video. Im getting ready to have a Trane XR14 2.5 tone outdooe unit installed in ny 1100 sq ft home in SouthWest Missouri. Whats your take on tge XR14 Trane units these days? Im replacing a 25yr old 10 seer 2.5 tone AC that still works but looking for more effency from my electric company. Cost is $5500 installed. Any tips I should watch out for during the install?
why did the evap coil have a different sized piston than the one in the bag from the condenser? And why use one over the other?
Can i keep my existing copper lines they were used with R22 gas?
awesome video -- thanks !!!!
Im looking at buying my new indoor/outdoor unit. it looks like there is a option for a/c only but also heat pump/furnace...how can i tell what system i currently have? I'm also going up a half ton due to a add on to my house.
A heat pump will have a reversing valve. If you look down in the condenser, it looks like a cylinder with two perpendicular pipes coming off of it and some wires going to it.

can I don't just exchange the evaporator coil without the case ? , that's what's leaking on our unit
So I need to replace my mother-in-laws ac unit, and she is on a limited budget. How do you buy one of these units? I went to ac dealers and said you need to be a dealer to buy a unit.
Can you tell us to be order how to check size?
Do you have to replace this part?
Hey bud when you change out a condenser do you have to do a coil also thanks in advance
You don’t have to, as long as the coil is 410a. If it’s r22 you can’t run a 410a condenser. The r22 coils are not designed for the higher pressures unless stated on the coil itself.
@@diyhvacguy thanks my buddy appreciate the advice and quick response
@@diyhvacguy thank you fine sir
Does the evaporator coil have to be replaced or can we stop after your part 1 video if our ac unit is working fine but we just want to replace with a more efficient unit?
Totally. I should make a video answering that question. I’ve replaced a condenser because the compressor locked up, and left the Evap coil and it ran for many more years. It all depends on if the compressor has a burnout or not. You’ll know if it has burnout immediately after opening the lines. It’s the worst burnt smell you’ll ever smell.
@@diyhvacguy that was the answer to the question i was looking for as i scrolled here. Perhaps add that to the description of the video also. This video series is awesome. Thankyou for taking the time to put it all together.
Pro press AC fittings?
I love this series, thank you. Is there a better return air grill out there? My current grill resonates when the unit is running which is quite annoying.
Whistling?
@@diyhvacguy more like a hum. If I open it or put my hand on it the sound goes away.
Thanks for the info.
What if that suction line was smaller due to the older unit specs, and the new 410a Coil calls for a 7/8 suction line, what would you do??? Run a new line set or keep the existing one and use a reducer?
I’d run a new lineset. If it’s 3/4 lineset you could do a reducer, but I did one not too long ago that had 5/8 suction and the new one called for 7/8 so we had to pull a new line set
Is an evap-coil necessary to replace when replacing your a/c unit?
If your existing system is r22 only then yes, if it’s labeled r22 or 410a then you can more then likely just replace the condenser, but the r22 coils will not work with the higher pressure of 410a
Thank you sir. Knowledge is so cool 😎
Why the street 90 instead of regular 90 on the coil?
Can I just replace the condenser and not the coil?
Hello there, my question is, do I have to get new line set if I'm moving from R22 to 410A? Also do I have to change the A coil as well?
No, you do need to flush the lines however, and the coil will probably need to be replaced unless it states r22 OR 410a on the case
Thank you very much for taking the time to respond directly.
Great video. I have two questions please. Is this unit using the fixed orifice instead of TXV?
Why do you have to change the orifice from .65 to .7?
Because the condensing unit dictates what orifice is needed. That’s why all new condensing units come with one stuck to the side of it. And yes this unit is using the fixed orifice. Much simpler and less to go wrong.
Is it necessary to change the coils if the outside unit is replaced?
My thoughts exactly. Is part 2 necessary if your just upgrading your unit outside?
So basically what you are saying is rather than find the leak you just opted to sell a new unit? Compressors usually get noisy when they're low on refrigerant and oil.
I would have located the leak and given the customer the option of repairing or replacing. I'm sure you did that along with recovering the freon with a reclaiming machine.
I have a 2.5 ton r22 unit. can I replace it with R401 3.5 ton? what do I need to buy? or Can I just buy a new condenser r22? please help
Hey, so you can’t go up a whole ton, you will have issues. I’d recommend replacing with the same size as what is there. So we offer a remote assistance service over at Patreon.com/diyhvacguy where we will help you find equipment and get it replaced. If that’s something you’re interested in, check it out! We have helped tons of people do their own replacement. Cheers
is it necessary to replace the ac coil?
I have a 20-year-old system that I want to change. My system uses r22, but I noticed a lot of newer systems use 410A.
My questions are. Why didn't you completely change out the air handler? And if i just replace the evaporator coil like you did in this video, will it make it an issue with running 410a in an air handler that was originally r22? I'm just wondering if I should make sure the blower motor is replaced also and not just the evaporator coil.
The blower has nothing to do with the coil. It’s completely separate. If it were me I’d replace everything. The customer just didn’t want to replace the furnace that’s why we only replaced the coil and condensing unit. No harm is done if you just replace the coil and condenser. If you need help finding the right system, feel free to email me and I’d be happy to help. Stojicrepair@gmail.com
@@diyhvacguy I've seen videos were HVAC technicians added freon to compensate for the long freon lines. Is that not a necessary step or is it recommended?
@@That1GuyOnRUclips if it’s longer then 20’ then yes you may need to add some. But most jobs are under 20 ft. If you did a system yourself you can always have a technician come and top it off and check the superheat and subcooling.
If the compressor has a burnout, does that mean you HAVE to change out the evaporator coil? or can it be flushed out?
Yes, it’s very hard to flush the Evap coil so my recommendation would be replacing. You can however flush the lineset and be ok. A burnout is pretty uncommon though.
WHERE DO YOU BUY THAT FLARING TOOL BIT ? AND WHAT SIZE IS IT ? I'M IMPRESS, THANKS
Good job
Thats a pretty involved process, but it definitely seems doable.
Is it possible to install a new unit directly up against the wall of the house? We have a small patio and the old unit is smack dab in the middle so we want to install a new one right up against the house. Even better, wish they made wall hanging units!
You could get creative and hang the condenser up height with some brackets, but for it to be up to code it needs to be at least 6” off the wall.
Does this also apply to heat pumps?
Will the duct sealant keep you from installing a new A coil in the future?
No, it might make it a bit more difficult as the duct sealant gets oretty hard but it’s not too bad.
Is this considered a furnace?
