hey guys I'm going to show you how to do a air handler indoor air handler service today this
is what the cooling mode might be a few little small things to do differently for the heating
mode but it's gonna be a preseason cooling mode service so it's relatively straightforward and
I'll show you the outdoor unit on a different video which I'll put a link down below for
that so anyway let's get started alright so here here's what we got we've got a indoor unit this
is a heat pump air handler and I've got this is the door you want to look for you call look for
your line set going in new copper tubes that means it's going to the call and then of course you're
gonna have your drain over here first thing on a visual inspection what you want to do is look at
your pant if it's up in the attic you're gonna have a pan on it if it's down in a crawl space
or a basement you may not so anyway look at your pan it's light so you can take a better look and
just see what the pan looks like the pan will tell you a lot if you can see this one spot right here
see where it's a little white that means there's water been there if your pans solid white on the
bottom water's been in it at one time or another if it's very white you'll have a ring right here
on the edge and very noticeable that means you've had water in there numerous times and if you have
any rough spots that means you've had a constant problem with this unit so it's not your unit you
don't know the history that's what you need to look for it's looking the pan it tells you a
story and if you had numerous problems you need to check your drain line go outside to where it
ends find out where it terminates and it might even be covered with with dirt you know pine
straw landscaping material whatever anyway I'm gonna pull this door off here and this is going
to give me access to my core and it's very important to know how the air flows on these
things air flows from left - right so that means when I clean this thing I need to clean this side
of the coil and this is the drain pan I'm clean that drain pan if I was to pull this panel off
and clean this side of the coil coming from this direction that way it's not gonna do me any good
because my dirts gonna accumulate on the side where air flows let me get in here and get you a
good view it's not much on there but it definitely is son so get in there with the coal cleaner and
and I'm going to spray this down this is indoor pool cleaner itself rinsing pool cleaner well
you don't have to rinse it off if you're gonna run it in air conditioned mode afterwards we're
still running a little bit of heat from time to time so I'm actually going to take water and back
spray this coal back home once I finish to make sure it's all good let me get my light in here
but I'm trying not to do this on a test stand or something so you can see real deal how it's
doing at your house everybody house is a little bit different sometimes people are lucky enough
to have these things in basements and they're easy to get to but most cases they're not just
like this one got to get on your knees and get at it but it's really important to keep this thing
clean you can't get good pressure readings and test your full refrigerant if the coil stopped
up and also this drain just cleaner going to go down three my drain and help clean my drain
cleaner but don't use a real horse indoor cleaner it will foam up that bone you go cut your air
handler own if you don't rinse it off that phone will get in your motor and your motor is gonna
be toasted so don't do it don't buy some heavier outdoor cleaner and stick in here cuz I've seen
people do it before and you gotta burn in your motor did you think they'd do that and the brand
I'm using here is Triple D I've used Triple D the years and years and years and it's always
done a good job and it's happy enough if you mix it highly-concentrated you can use it for outdoor
cleaner - all right and that's already dirty and there's the bottom of the core there and you can
see this cleaner is running right off and straight down into my drain and i want cleaning my drain
out at the same time anyway that's that and i'ma empty out my cleaning jug here and I'm gonna get
some water and I'm gonna rinse it off and then I'll show you what to do on the blower section
what do on it and I got the indoor unit clean indoor cool spotless actually and I'll put this
on here years ago this is actually a pretty cool feature it's a lid that you can lift up and you
can clean your drain line out and it comes with a little flap you can put this flap in here and
point it one way put your air tank on it and blow it out or put the flap the other way and
blow it other direction case it gets clogged so pretty cool little deal if not they make a
trap with a brush that's clear that you can use that I've used them too so anyway both of them
work real good that's clean you can strap that back and here make sure your power is off and
get you a cleaning rag and two things you want to do in the blower section make sure you will
and all that's clean and just grab your your blower motor go side to side with the wheel if
it goes side to side and you feel bumping then you've got some bearing where if it don't then
you're good it will have some up and down play in here on the bottom or the top it comes on how
you're positioned but just take your rag and go ahead and clean all your well let's go watch oh
because they're gonna get moldy and they're gonna be nasty and just wipe it down just trying to do
this in one hand so it might be a little shaky hit the bottom your motor as well and you can see what
came off of there but some of them I go to hasn't been done in years the motor would actually get
clogged with dirt and debris and that's how the motor is cooled by the air look at your drain
pan on the inside and wipe it now you see if I can get this we grab everything wipe all this
down real good you can see what's coming off of it everything sucks air and everything is gonna
collect dust it's wet and damp and everything else so wipe your whole machine down blower motor Bowl
wheel everything next thing you want to do is come into your little second section check your wires
check your incoming and I've got the power off check the incoming power wire make sure they're
tight check your state cons on your terminal boards make sure nothing is discolored from
running in the heat mode they can get discoloured take control board on the bottom or top whichever
position it is make sure there's no corrosion on it from any mildew or water from last year
and then the last thing you'd want to do or you can do it before then and don't really matter I
use just drain pan tablets get you a tablet and normally I break them in half and put them let
me get this where you can see what's going on in this pan here now you can see the pan and normally
I just take one and I throw it on one side of the pan and then put one on the other side place
it in a position where it's a good position and that's going to help keep the drain line clear
all next summer one thing don't do is don't stick it right here by your drain line because it can
get in there stop you hole up now I'm gonna put my panels back on and endure your handler is serviced
