00:00:00.060 all right I just got through pulling 00:00:01.85000:00:01.860 this evaporator so what I'm going to do 00:00:05.03000:00:05.040 is kind of give you a short overview 00:00:07.57900:00:07.589 about how to if you're at home and you 00:00:11.06000:00:11.070 want to try to clean your own coil in 00:00:12.62000:00:12.630 place how you can do it the easiest way 00:00:27.80000:00:27.810 or the best way not the easiest way but 00:00:30.52900:00:30.539 the best way to clean an evaporator coil 00:00:34.10000:00:34.110 like this one right here is to actually 00:00:35.69000:00:35.700 pull it and clean it if you're so 00:00:39.08000:00:39.090 inclined to do it at your house 00:00:47.03000:00:47.040 you see screw right there screw right 00:00:51.12000:00:51.130 there 00:00:51.60000:00:51.610 screw right there screw right there and 00:00:54.26000:00:54.270 the screws at the bottom you can take 00:00:56.88000:00:56.890 those out and this little Center 00:00:58.61000:00:58.620 triangle sheet metal piece comes out but 00:01:01.44000:01:01.450 what you got to be careful of is these 00:01:03.03000:01:03.040 little feeder tubes I had a call on a 00:01:07.49000:01:07.500 Saturday night a few weeks ago a guy had 00:01:11.55000:01:11.560 tried to pull this thing apart while it 00:01:14.28000:01:14.290 was in place and he actually rubbed 00:01:17.28000:01:17.290 against one of these little feeder tubes 00:01:18.71900:01:18.729 and ruptured it and he called me in a 00:01:22.02000:01:22.030 frantic saying help I ruptured a tube 00:01:26.60900:01:26.619 and now I will do free on everywhere so 00:01:32.28000:01:32.290 it's always best I try not to ever take 00:01:35.16000:01:35.170 this sheet metal piece off I'm a 00:01:37.35000:01:37.360 professional for you know sometimes I'm 00:01:40.53000:01:40.540 a professional but I try never to take 00:01:44.21900:01:44.229 that off just because I don't want the 00:01:45.81000:01:45.820 liability of rupture one of these tubes 00:01:48.90000:01:48.910 or causing a leak myself I always 00:01:52.41000:01:52.420 suggest that the coil just gets replaced 00:01:54.30000:01:54.310 instead getting cleaned because once you 00:01:57.69000:01:57.700 pull it and clean it you do take a 00:01:59.60900:01:59.619 chance on cause an egg freon leak now 00:02:03.16900:02:03.179 another reason you don't want to just 00:02:05.30900:02:05.319 clean it in place is if you see all this 00:02:09.21000:02:09.220 dirt right here 00:02:58.78900:02:58.799 now the reason you don't want to just 00:03:00.96000:03:00.970 clean it in place if you see all this 00:03:04.89000:03:04.900 dirt right here that's actually the dirt 00:03:08.12900:03:08.139 that's got sucked inside of the fence if 00:03:10.67900:03:10.689 you just try to clean the inside of it 00:03:14.03900:03:14.049 you'll never get all of the stuff from 00:03:18.00000:03:18.010 inside the fence now they sell stuff at 00:03:20.19000:03:20.200 Home Depot that you can use and the 00:03:22.17000:03:22.180 problem with it is it foams up and what 00:03:24.72000:03:24.730 happens is it drop step inside the 00:03:26.36900:03:26.379 blower housing and then you take a 00:03:29.33900:03:29.349 chance on shorting the motor out so you 00:03:31.64900:03:31.659 know you can try to clean it in place if 00:03:33.44900:03:33.459 you want to but the problem is is you're 00:03:35.03900:03:35.049 not going to get it clean enough to 00:03:36.89900:03:36.909 where it's working properly and in it 00:03:39.00000:03:39.010 but guys been out and he just put freon 00:03:41.67000:03:41.680 in it and he didn't check super heat 00:03:44.18000:03:44.190 then you have a situation where you use 00:03:47.28000:03:47.290 it's probably overcharged like this unit 00:03:49.46900:03:49.479 right here is probably going to be 00:03:51.08900:03:51.099 overcharged so they did have a guy come 00:03:53.09900:03:53.109 out and check the freon and he added a 00:03:55.43900:03:55.449 little so it's actually going to 00:03:57.59900:03:57.609 probably be overcharged when we get done 00:04:00.08000:04:00.090 you know and in a unit too much freon is 00:04:05.06900:04:05.079 just as bad if not enough anyway I'm 00:04:07.80000:04:07.810 going to show you the inside here what's 00:04:10.46900:04:10.479 the thing over you see 00:04:17.03900:04:17.049 and it's always best we try to clean 00:04:19.77000:04:19.780 these things when they're dry if you're 00:04:21.30000:04:21.310 going to try to do it yourself it's 00:04:25.83000:04:25.840 always best to try to do it when it's 00:04:27.39000:04:27.400 dry because when this dirt gets a dirt 00:04:30.65900:04:30.669 or when it gets wet it's like a it's 00:04:33.83900:04:33.849 like mud say got all that hair now I've 00:04:39.65900:04:39.669 got a little thin column I can use try 00:04:46.52900:04:46.539 to pull some of the stuff out of here 00:04:53.39000:04:53.400 but as you see it's not the easiest 00:04:56.12900:04:56.139 thing to do and I'm right here on top of 00:04:57.71900:04:57.729 it so imagine how long it would take you 00:05:00.89900:05:00.909 if you were trying to do this in place 00:05:03.86000:05:03.870 so it's just better sometimes just to 00:05:06.93000:05:06.940 call somebody 00:05:07.74000:05:07.750 have them pull it and clean it and you 00:05:10.98000:05:10.990 know that way they can check the charge 00:05:12.33000:05:12.340 making sure they use superheating 00:05:14.24900:05:14.259 subcooling 00:05:15.74000:05:15.750 you know that way you get a good running 00:05:20.10000:05:20.110 system after the fact look at that 00:05:25.49000:05:25.500 anyway so I'm gonna get this thing 00:05:28.11000:05:28.120 sprayed off and get it all cleaned up 00:05:34.24900:05:34.259 see how it's just pulling off and in 00:05:36.65900:05:36.669 sheets and like I said I'm standing 00:05:43.98000:05:43.990 right on top of this and I'm not trying 00:05:45.51000:05:45.520 to reach through the center of the coal 00:05:46.98000:05:46.990 to try to pull this stuff off so you not 00:05:51.65900:05:51.669 just pulling off there 00:05:55.12900:05:55.139 and it is a dirty job I don't know if 00:05:57.62900:05:57.639 you can see all that dust coming through 00:05:59.12900:05:59.139 but you know if you're standing in front 00:06:01.35000:06:01.360 of it trying to pull it off you know you 00:06:03.83900:06:03.849 can breathe breathing all this stuff in 00:06:05.87000:06:05.880 so like is that it's just better not to 00:06:08.99900:06:09.009 try to do it yourself and just call 00:06:10.43900:06:10.449 somebody that can actually pump and pump 00:06:13.89000:06:13.900 the unit down pull it out take it 00:06:17.58000:06:17.590 outside wash it 00:06:31.48000:06:31.490 all right now got my water hose out you 00:06:34.31000:06:34.320 can see that what is taking in St Kilda 00:06:39.98000:06:39.990 stuff off and here in the second I'll 00:06:43.04000:06:43.050 show what it's like to shoot from the 00:06:45.23000:06:45.240 other side that's where I'm saying you 00:06:47.30000:06:47.310 cannot get these things 00:06:50.17000:06:50.180 clean in place very well 00:06:52.44000:06:52.450 this wire is set in the furnace to pass 00:06:54.81000:06:54.820 and pulling them clean 00:06:58.18000:06:58.190 so now that you see that side right 00:07:00.55000:07:00.560 there let's see what happens now we're 00:07:04.78000:07:04.790 playing from the outside in and as you 00:07:08.59000:07:08.600 see you can't get that stuff off it 00:07:13.54000:07:13.550 so what I'm doing is I'm is I'm washing 00:07:16.71900:07:16.729 it off getting all the dirt off from the 00:07:19.71900:07:19.729 inside well he's doing it from the 00:07:21.67000:07:21.680 outside record seconds but 00:07:25.82000:07:25.830 I'm going to finish doing what I'm doing 00:07:28.55000:07:28.560 with the water hose from the inside and 00:07:30.37900:07:30.389 I'll take my coil cleaner and we'll 00:07:33.35000:07:33.360 shoot it from the outside let it foam up 00:07:35.54000:07:35.550 and we'll get this sucker clean all 00:07:42.17000:07:42.180 right so you got my coal sprayed out and 00:07:45.65000:07:45.660 see all the stuff that's coming out of 00:07:46.85000:07:46.860 it 00:07:47.39000:07:47.400 only stuff so as you can see you can't 00:07:51.98000:07:51.990 really get it clean in a place you have 00:07:54.83000:07:54.840 to all this stuff is just bubbling up 00:07:57.20000:07:57.210 from the inside of the coal so you know 00:08:00.05000:08:00.060 you can't can't get it clean from just 00:08:03.55000:08:03.560 clean it from the inside 00:08:06.46000:08:06.470 all right so we got the coal clean in 00:08:09.17000:08:09.180 place there's some stuff laying there 00:08:11.60000:08:11.610 and then some of stuff laying on the 00:08:14.05900:08:14.069 ground there but we cleaned it now we're 00:08:17.48000:08:17.490 getting ready to take it inside and wash 00:08:20.96000:08:20.970 it yeah it's pretty nasty in it and 00:08:25.18000:08:25.190 that's like I said that's that's when 00:08:27.68000:08:27.690 it's wet and I mean it's just you can 00:08:31.18900:08:31.199 see you look like spinach finish out of 00:08:35.24000:08:35.250 the candy I'm not eating there you go so 00:08:40.25000:08:40.260 it looks like almost a new coal now 00:08:44.42000:08:44.430 let's go put it in alright so the coal 00:08:46.31000:08:46.320 is in its final resting place for 00:08:48.49000:08:48.500 también anyway till it develops a leak 00:08:52.09000:08:52.100 then it will be changed getting ready to 00:08:56.48000:08:56.490 put the cover back on and then once I 00:09:00.35000:09:00.360 get to cover back in place 00:09:01.69900:09:01.709 then I'll swedge this and then I don't 00:09:04.79000:09:04.800 have a 5/16 wedge or so what I'm going 00:09:08.06000:09:08.070 to do is I'm going to take a piece of 00:09:09.13900:09:09.149 3/8 wedge it on both sides slip that 00:09:12.44000:09:12.450 over like a little coupling and then 00:09:16.13000:09:16.140 we'll get it put back in place get it 00:09:18.82900:09:18.839 braised up get it back and pulled on it
