okay i hope everybody's doing good well the unfortunate happened in the middle of summer the
ac systems in my house decided to take a so last year i put this one in had pretty good
success did it myself by no means am i saying that this is a how-to video or anything i do
have my hvac certifications and free on handling certification so whatever you decide to do at your
own home is on you check your local state regulations and laws on each installation
so this armani unit decided to take a [ __ ] on me and basically the compressor went out
so instead of just replacing the compressor i went ahead and just bought brand new goodman units
same one as this one this one's been performing flawlessly for the past year super quiet this is a
older goodman unit here it's a r22 and this is also a r22 that's a 410 that's a 410. this
one is extremely noisy and i have some r22 and i had to fill it back up a little bit
and now we're gonna go ahead and get on with the install this one make sure all your power shut
off at your breakers at your disconnect the first thing you want to do is if your system is already
empty from a hole then you're good if not you have to drain down the system into a recovery
tank if you can't do it get somebody locally do it they may charge you you know 100 bucks
or so but do not vent it into the atmosphere it's definitely bad for the ozone definitely
illegal so if you see here i just disconnected the main whip coming in which is your 240 power
oh jesus christ did you see that
that's gonna be a funny part of the video two locus is back here
jesus christmas scared the hell out of me
well that was pretty funny definitely not going to edit that one out
um so yeah we're going to take out our 240 whip here it's disconnected there's no power
or anything like that and just set it off to the back out of the way so it's not on your way
and then you're going to get the freon sucked down
and then you have to cut the lines so let me get the freon out of here and then we'll be back
okay once you've successfully recovered your freon you're going to cut the suction
and discharge lines with a copper cutting tool and get everything free
okay it might be difficult to get the lines out but you can bend them get them cut as close as
you possibly can to have as much line as you can and that's it now your outside condensing
unit is disconnected let's move it out of the way and get the new one in place
all right we're at the indoor air handler now same deal you want to disconnect your
suction discharge lines and your power all your stuff coming in you want to disconnect
all that and you want to get your pump out of there so let's get all this stuff out
all right this is probably the hardest part honestly is getting the air handler moved off the
return and supply ducts so make sure you get all the screws and peel all the plaster off and get
all the electric wires out and cut everything and now you want to slide your new one back into place
all right once you get the box installed
get everything tightened in this install was not easy because this box was not the same size
but i made it work so now on to cleaning the lines out we'll just have to spray
some dry nitrogen through it with a little spray nozzle and make sure the lines are cleaned out
and we'll continue on all right we're back now we're gonna start the brazing process this is the
most critical process of the install if you don't get this right you might as well throw it all away
so we cleaned off the copper fitting down there if you see
right in there we sanded it all up got it nice and shiny again back to good copper
uh there's some key components you're gonna need you're gonna need some flux to put on there
you're gonna need some water and a rag to wrap the valves up so you don't heat the valves up when
you're sweating them uh got some stay silver five brazing rods you're gonna need some oxy
acetylene i keep that pretty far away from me while i'm working in case something goes wrong
and the very most important part that you need you are going to need nitrogen while you're brazing
and this is a nitrogen flow meter that shows me with that little orange ball if
you see it says braze 3 to 5 psi that's so you don't blow your tip out while you're brazing
this will keep soot and everything else from forming and keep it all out of your system
so we're going to get this first line brazed up make sure you take the schrader valves out
got everything hooked up and we are ready to go so let me get these lines braised in now
all right get the braised lines all in and you go and do the inside unit the same way
all right when you're at your inside air handler at the coil they're charged with
nitrogen from the factory to ensure no leaks and if you can hear that
there's nitrogen in there which means that this case was holding just fine and nitrogen
will just purge out and we'll get everything all put in all right so now that everything is done i
charge the system with nitrogen and i'm going to wait to see if we have any leaks
okay so we waited about 30 minutes i left it sitting at about
200 psi on the low side and just under one line on the high side and 200 and it's held fine so
that means the system's good let's get everything wrapped up and we're gonna have to vacuum it down
all right we got the air handler installed everything's set in place all the mastic
tape is dry i just got a dehumidifier going because it's underneath in a crawl space
keep it nice and dry in here got the mastic tape is all done around there
everything's sealed in well ring feels good so once you get that installed you're pretty much
done i added a uv light in there to kill bacteria and anything else a little uv light i got and it
has a transformer up there that's wired in 24 volts so yeah that's pretty much it i'm
gonna get the cabinet closed up and then we're gonna check the output temperature
okay we're inside at the vent we're gonna see how much the air handler is pushing out
so
now you can hear how quiet these ones are you can hear me just fine
and wait until that third one runs
it's probably twice to three times as loud
so yeah hope this helps somebody out if they have some questions about installing a hvac unit at
their house and saving some money again i'm not a professional check your local and state laws
