00:00:05.300 hey I'm Larry janeski from dr. Energy 00:00:07.91000:00:07.920 Saver and I'm Kelly laughs ler from dr. 00:00:10.24900:00:10.259 Nancy saver and mines air conditioning 00:00:11.86900:00:11.879 and the Orlando Florida area we're here 00:00:14.65900:00:14.669 in this southern climate to talk about 00:00:17.30000:00:17.310 something that is incredibly important 00:00:19.27900:00:19.289 for homeowners here and that's air 00:00:20.54000:00:20.550 conditioning yes you know it gets so hot 00:00:23.33000:00:23.340 down here in the south and we need to be 00:00:26.96000:00:26.970 able to cool our houses to make them 00:00:28.42900:00:28.439 comfortable in fact that's really the 00:00:30.16900:00:30.179 point of a house is to make a 00:00:31.40000:00:31.410 comfortable environment for people to 00:00:33.71000:00:33.720 live and we can spend a lot on air 00:00:37.52000:00:37.530 conditioning or a little on air 00:00:38.96000:00:38.970 conditioning at the cost of running it 00:00:40.49000:00:40.500 we can make our houses more or less 00:00:42.83000:00:42.840 comfortable depending on the equipment 00:00:44.27000:00:44.280 that we use first we're going to talk 00:00:45.77000:00:45.780 about low efficiency air conditioning 00:00:47.87000:00:47.880 Kelly what do we have here what we have 00:00:50.21000:00:50.220 here is a 17 year old carrier unit it's 00:00:53.39000:00:53.400 about a 3 ton system as you can see it's 00:00:57.77000:00:57.780 been sitting here for quite a while you 00:00:59.24000:00:59.250 can see all the oxidation we have a palm 00:01:01.31000:01:01.320 tree even that's grown up behind the 00:01:02.78000:01:02.790 unit which really helps doesn't help it 00:01:05.95900:01:05.969 much it pushes it out off the back of 00:01:07.34000:01:07.350 the pad okay let's sit forward you can 00:01:10.09900:01:10.109 see down here alone the edges how this 00:01:11.63000:01:11.640 has been moved sideways and every other 00:01:13.16000:01:13.170 directions sitting right now good three 00:01:15.31900:01:15.329 inches off the pad right so so this is 00:01:17.81000:01:17.820 17 years old yes I said now what does 00:01:22.81900:01:22.829 that tell us that it's 17 years old what 00:01:24.62000:01:24.630 do we know right off the bat well what 00:01:26.23900:01:26.249 we know right off the bat is we're 00:01:27.38000:01:27.390 dealing with a lower efficiency unit and 00:01:30.26000:01:30.270 as most people may not understand even 00:01:32.20900:01:32.219 though they may have a six or eight seer 00:01:34.52000:01:34.530 unit over time these units actually lose 00:01:37.19000:01:37.200 efficiency so it could be operating at a 00:01:39.67900:01:39.689 six or four seer at this okay so now 00:01:42.13900:01:42.149 when we say seer we mean that's SCE our 00:01:45.49900:01:45.509 what does that mean 00:01:46.48900:01:46.499 what that is is that's your seasonal 00:01:48.49900:01:48.509 energy efficiency rating and that tells 00:01:50.77900:01:50.789 you basically how efficient the units 00:01:53.09000:01:53.100 running the less efficient iran's the 00:01:55.21900:01:55.229 more energy it costs to run the unit so 00:01:57.59000:01:57.600 by looking at these you can see they 00:02:00.52900:02:00.539 these homes typically are going to spend 00:02:03.02000:02:03.030 a lot more money on air conditioning 00:02:04.16000:02:04.170 than a newer home or a newer unit on a 00:02:06.10900:02:06.119 home okay so when we say how efficient 00:02:09.53000:02:09.540 it is the efficiency rating 00:02:12.32000:02:12.330 doesn't that mean how if 00:02:14.75000:02:14.760 fishing it is at turning electricity and 00:02:17.80900:02:17.819 I'm going to call that that dollars okay 00:02:20.36000:02:20.370 because we pay for electricity correct 00:02:22.42900:02:22.439 how efficient is it is it at turning 00:02:25.13000:02:25.140 dollars into cold air right yes okay so 00:02:28.42900:02:28.439 this seer rating on this when it was new 00:02:30.89000:02:30.900 might have been you said six 00:02:32.99000:02:33.000 probably a six or eight seer unit at 00:02:34.91000:02:34.920 most okay and now it's old it's running 00:02:37.75900:02:37.769 at probably a four to six years what 00:02:39.64900:02:39.659 we're running out all right so it's that 00:02:41.27000:02:41.280 the the state of the art today what's 00:02:44.21000:02:44.220 the highest seer rating that we can get 00:02:45.83000:02:45.840 in a brand-new unit the highest seer 00:02:47.27000:02:47.280 rating you can get on a brand new unit 00:02:48.83000:02:48.840 is around 19 or 20 seer so 19 or 20 seer 00:02:53.11900:02:53.129 and this thing is running at four that's 00:02:55.52000:02:55.530 a big reason to upgrade isn't it yes sir 00:02:57.31900:02:57.329 all right so Kelly ultimately the heat 00:02:59.21000:02:59.220 from the house is escaping out of the 00:03:02.39000:03:02.400 air-conditioning through these little 00:03:03.55900:03:03.569 fins or might call it a radiator people 00:03:06.47000:03:06.480 understand what that is and so the heat 00:03:09.80000:03:09.810 is coming off of here right yes sir and 00:03:11.93000:03:11.940 then if we have vines and weeds and and 00:03:15.08000:03:15.090 leaves and stuff growing up around here 00:03:18.05000:03:18.060 then what happens well what happens is 00:03:20.05900:03:20.069 just like you say a car radiator as you 00:03:22.22000:03:22.230 block air flow it builds up heat it 00:03:25.46000:03:25.470 pauses the unit to malfunction works 00:03:28.55000:03:28.560 harder so it takes more dollars to make 00:03:30.68000:03:30.690 that cold air as we said earlier okay 00:03:32.75000:03:32.760 what do we got on this side we have two 00:03:34.86900:03:34.879 refrigerant lines coming here what l us 00:03:37.58000:03:37.590 about these well what you have here is 00:03:39.17000:03:39.180 you have your your two person line your 00:03:41.24000:03:41.250 liquid line your suction line and with 00:03:44.05900:03:44.069 this as you can see over time this 00:03:45.89000:03:45.900 installation is broken down from all of 00:03:47.75000:03:47.760 the hot and humid air so it's no longer 00:03:50.90000:03:50.910 has that insulating factor that at once 00:03:52.58000:03:52.590 David so this is the cold line yes sir 00:03:54.71000:03:54.720 and so we're making our refrigerant cold 00:03:59.08900:03:59.099 we're sending it inside to another 00:04:00.74000:04:00.750 radiator that we have a blower blowing 00:04:03.50000:04:03.510 over the cold coil and then sending that 00:04:06.11000:04:06.120 cold air to the house but this has no 00:04:08.24000:04:08.250 insulation whatsoever correct you can 00:04:10.22000:04:10.230 see it's broken in a number of spots on 00:04:11.96000:04:11.970 its way in yeah and even the parts that 00:04:14.53900:04:14.549 do this is not as effective as it once 00:04:16.84900:04:16.859 was all of the outside covering as you 00:04:19.21900:04:19.229 can see is peeling away it's dry rotting 00:04:22.25000:04:22.260 on top of it okay so this is another 00:04:24.44000:04:24.450 place where we're 00:04:25.74000:04:25.750 losing efficiency yes sir okay so Kelly 00:04:28.29000:04:28.300 here we have a 17 year old evaporator 00:04:32.52000:04:32.530 coil and blower and what do you see here 00:04:34.92000:04:34.930 well what you see here is you can see 00:04:36.75000:04:36.760 just how dirty the inside of this unit 00:04:38.73000:04:38.740 is from not being maintained it it's 00:04:40.62000:04:40.630 terrible I mean look at this oh gosh and 00:04:44.91000:04:44.920 you see dirt this is just black with 00:04:48.21000:04:48.220 dirt and this is where your air supply 00:04:49.80000:04:49.810 that you're breathing is running through 00:04:51.69000:04:51.700 here correct as you can see it's it has 00:04:55.53000:04:55.540 a lot of rust over time from water just 00:04:57.72000:04:57.730 the dirt sitting on top of at night like 00:04:59.37000:04:59.380 you said your air flows through here 00:05:01.17000:05:01.180 across this cold coil and blows through 00:05:03.72000:05:03.730 the plenum to the rest of the house and 00:05:05.34000:05:05.350 that's what creates your cold air in 00:05:06.96000:05:06.970 your air conditioning in the home mm-hmm 00:05:08.70000:05:08.710 and you see oh my gosh even on the wires 00:05:11.55000:05:11.560 you got organic growth and on the 00:05:14.73000:05:14.740 insulation on the inside of the cabinet 00:05:16.50000:05:16.510 organic growth and the people in the 00:05:18.72000:05:18.730 Southside a lurch ease I guess they do 00:05:20.67000:05:20.680 the one daughter has pretty bad 00:05:22.38000:05:22.390 allergies and so does the father yeah so 00:05:24.60000:05:24.610 you know it's really no wonder you're 00:05:26.55000:05:26.560 running your entire air supply through 00:05:29.19000:05:29.200 this this really dirty infested 00:05:33.65900:05:33.669 environment constantly and that these 00:05:37.62000:05:37.630 people obviously haven't had this 00:05:39.12000:05:39.130 service and sometimes no you could tell 00:05:41.94000:05:41.950 it if it's serviced one of the things 00:05:44.46000:05:44.470 that the air conditioning companies will 00:05:45.84000:05:45.850 generally did will come in you'll clean 00:05:47.76000:05:47.770 the coils you would not have this 00:05:50.04000:05:50.050 build-up just across it the contactors 00:05:52.44000:05:52.450 would not have the corrosion that you 00:05:53.88000:05:53.890 can see along the wire because we would 00:05:55.44000:05:55.450 have replaced that and just keeping a 00:05:57.90000:05:57.910 better working state so yeah they need 00:06:01.23000:06:01.240 to have your company start a service 00:06:02.49000:06:02.500 program yes they do yeah okay so any age 00:06:06.36000:06:06.370 air conditioner needs to be maintained 00:06:09.63000:06:09.640 right yes we recommend at least once a 00:06:12.48000:06:12.490 year from the time it started especially 00:06:14.88000:06:14.890 if you have extended warranties these 00:06:16.92000:06:16.930 days the manufacturers require manual 00:06:19.62000:06:19.630 maintenance on to keep them operating at 00:06:21.33000:06:21.340 peak performance okay let's take a look 00:06:23.67000:06:23.680 at the some of the supply girls and see 00:06:26.70000:06:26.710 if they're dirty now Kelly we have our 00:06:28.95000:06:28.960 return box here and we have this central 00:06:31.89000:06:31.900 return but I see a lot of dirt on here 00:06:35.21900:06:35.229 correct oh my gosh this is terrible 00:06:38.52000:06:38.530 that's where all the 00:06:39.51000:06:39.520 and home is being pulled through and as 00:06:41.79000:06:41.800 you can see there's just a large buildup 00:06:43.32000:06:43.330 of dirt and dust and other items that 00:06:45.15000:06:45.160 again you hope that your filter will 00:06:47.70000:06:47.710 catch all but it won't catch all of that 00:06:49.37900:06:49.389 so in this case we're sucking return air 00:06:52.68000:06:52.690 from really close to the floor 00:06:54.30000:06:54.310 yes where we can have a lot of dust and 00:06:56.27900:06:56.289 so forth sucking it right into the air 00:06:57.99000:06:58.000 conditioner 00:06:59.07000:06:59.080 we have ductwork in the Attic there's a 00:07:01.52900:07:01.539 leakage in the ducts in the attic we can 00:07:03.65900:07:03.669 add dirt in that way and so all the more 00:07:09.24000:07:09.250 reason to have the system maintained 00:07:11.58000:07:11.590 regular basis is very important dirt is 00:07:14.39900:07:14.409 the number one enemy of air conditioning 00:07:16.32000:07:16.330 isn't it it is again it can clog up many 00:07:19.05000:07:19.060 items you have your standard filters 00:07:21.74900:07:21.759 there and they can only catch so much 00:07:23.33900:07:23.349 and what gets through remember gets into 00:07:25.92000:07:25.930 your air conditioning system gets into 00:07:28.20000:07:28.210 that coil as we saw previously which has 00:07:30.27000:07:30.280 very small slits and ruin the radiator 00:07:33.60000:07:33.610 fins as we say very small spaces that 00:07:36.20900:07:36.219 can clog with dirt right and again like 00:07:37.95000:07:37.960 you say it's like a radiator if you clog 00:07:39.89900:07:39.909 it up and you do not maintain it it just 00:07:42.05900:07:42.069 makes you to work that much harder it's 00:07:43.52900:07:43.539 much for less efficient all right well 00:07:45.68900:07:45.699 let's take a look at some well 00:07:47.30900:07:47.319 maintained high efficiency equipment the 00:07:49.49900:07:49.509 difference 00:07:49.98000:07:49.990 sounds good as you can see here this 00:07:53.96900:07:53.979 grill you see all the dirt around it 00:07:55.52900:07:55.539 this is the daughters and has all the 00:07:57.45000:07:57.460 allergies and and these are some of the 00:07:58.86000:07:58.870 causes you know you've got all this dust 00:08:00.71900:08:00.729 and allergens they could really use a 00:08:03.14900:08:03.159 duct cleaning as well as a new air 00:08:05.43000:08:05.440 conditioning unit you know people with 00:08:06.71900:08:06.729 asthma and allergies go to the doctor 00:08:08.61000:08:08.620 the allergist and they get prescriptions 00:08:10.98000:08:10.990 and take drugs and try to calm down the 00:08:13.46900:08:13.479 symptoms and yet the cause right in 00:08:16.62000:08:16.630 their house you're correct 00:08:18.11000:08:18.120 not good all right now Kelly you're not 00:08:21.08900:08:21.099 only doctor Energy Saver but you're in 00:08:25.20000:08:25.210 the air-conditioning business and how 00:08:26.87900:08:26.889 long have you been doing that well mines 00:08:29.37000:08:29.380 air conditioning heating has been in the 00:08:30.57000:08:30.580 business now for forty seven years it's 00:08:32.37000:08:32.380 family-owned we're third generation so 00:08:34.64900:08:34.659 you know a thing or two yes sir their 00:08:36.63000:08:36.640 conditioning and we're in Florida right 00:08:38.43000:08:38.440 yes all right so here it is this thing 00:08:41.39900:08:41.409 with sure is pretty 00:08:42.51000:08:42.520 it is a nice big unit isn't it all right 00:08:45.12000:08:45.130 so the first thing I noticed this is 00:08:47.22000:08:47.230 high efficiency air conditioning is that 00:08:49.76900:08:49.779 it stall yes tell us why the reason 00:08:52.59000:08:52.600 being is 00:08:53.19000:08:53.200 you have a much larger coil which is 00:08:55.80000:08:55.810 that radiator we spoke about earlier 00:08:57.12000:08:57.130 gives a larger surface for letting that 00:09:00.18000:09:00.190 air escape also you have inside two 00:09:02.88000:09:02.890 compressors it's a two-stage unit for 00:09:06.00000:09:06.010 more efficiency okay so so we have a 00:09:09.03000:09:09.040 bigger hot surface area to let the 00:09:11.58000:09:11.590 there's a fan in here that sucks air 00:09:13.53000:09:13.540 through the this unit here to let the 00:09:17.31000:09:17.320 heat escape correct right okay and then 00:09:20.36000:09:20.370 you said it two compressors a two-stage 00:09:25.62000:09:25.630 unit yessir knows what that means what 00:09:27.60000:09:27.610 it does is it allows the air conditioner 00:09:29.34000:09:29.350 to run at 70 percent of its total 00:09:31.68000:09:31.690 capacity when it's not required to run 00:09:34.50000:09:34.510 full-out so what happens is you can take 00:09:37.92000:09:37.930 a four ton unit like this and it'll run 00:09:40.47000:09:40.480 and roughly a three ton okay so when we 00:09:44.91000:09:44.920 say tons we mean twelve thousand beat 00:09:48.24000:09:48.250 what we mean is every time there's 00:09:49.74000:09:49.750 12,000 BTUs you're roughly forty eight 00:09:51.75000:09:51.760 thousand BTUs for a four ton unit that 00:09:54.24000:09:54.250 are required but when you're heating and 00:09:56.91000:09:56.920 cooling your house 00:09:57.78000:09:57.790 it doesn't always require it to run on 00:09:59.79000:09:59.800 the high stage to bring the temperatures 00:10:01.38000:10:01.390 down so if it's not real hot outside 00:10:02.73000:10:02.740 it's a little warm outside correct 00:10:04.77000:10:04.780 alright so we're not running you know 00:10:06.66000:10:06.670 full-out we're just running sort of on a 00:10:09.77000:10:09.780 low fuel economy so to speak okay 00:10:12.77000:10:12.780 alright so so when it's really hot out 00:10:15.36000:10:15.370 both compressors will kick in yes sir 00:10:17.04000:10:17.050 all right and what else about this unit 00:10:20.87000:10:20.880 what else you have that you'll notice 00:10:23.40000:10:23.410 also on these higher fish teams are very 00:10:25.02000:10:25.030 quiet you you don't even hear them 00:10:28.11000:10:28.120 running most of the time 00:10:30.66000:10:30.670 outside none of that with these units a 00:10:34.20000:10:34.210 lot of our customers they they'll even 00:10:36.00000:10:36.010 tell us you know I can't even hear it I 00:10:37.86000:10:37.870 have to go outside and check when they 00:10:39.00000:10:39.010 first get them to even see if they're 00:10:40.17000:10:40.180 running because I just don't believe it 00:10:41.52000:10:41.530 can be that quiet uh-huh beautiful 00:10:43.44000:10:43.450 I understand all heat pumps are air 00:10:45.99000:10:46.000 conditioners but not all air 00:10:47.22000:10:47.230 conditioners are heat pumps all right I 00:10:48.72000:10:48.730 was correct and this one is yes so what 00:10:50.76000:10:50.770 is it heat pump - what a heat pump does 00:10:52.53000:10:52.540 is it also not only does it cool your 00:10:54.54000:10:54.550 house but it will heat your house in the 00:10:56.04000:10:56.050 cold season okay so in the summer we're 00:10:58.92000:10:58.930 taking heat from inside the house and he 00:11:01.71000:11:01.720 is coming off of this and we're moving 00:11:03.81000:11:03.820 it outside so we can have cool air 00:11:05.55000:11:05.560 inside and then in the winter it's just 00:11:08.88000:11:08.890 reversing yes right we're taking heat 00:11:10.83000:11:10.840 from outside and moving it inside 00:11:12.54000:11:12.550 correct all right so it has to have a 00:11:16.20000:11:16.210 reversing valve yes it has a reversing 00:11:18.51000:11:18.520 valve in here which basically just takes 00:11:20.28000:11:20.290 it and turns everything the opposite 00:11:21.72000:11:21.730 direction and in doing so it takes that 00:11:25.80000:11:25.810 cold like you said the freon from before 00:11:28.53000:11:28.540 it goes inside a cold line it then 00:11:30.57000:11:30.580 reverses it and takes the heat off the 00:11:32.22000:11:32.230 compressors and puts that inside to the 00:11:34.11000:11:34.120 coil and allows it to blow that warm air 00:11:35.94000:11:35.950 and throughout your house so we get 00:11:38.19000:11:38.200 heating and air conditioning yes forward 00:11:41.22000:11:41.230 and reverse all right so here we are 00:11:44.19000:11:44.200 inside with this high efficiency air 00:11:46.13000:11:46.140 conditioning system heat pump right yes 00:11:48.66000:11:48.670 and we have our blower here yes and our 00:11:54.57000:11:54.580 evaporator coil our cold coil here 00:11:56.28000:11:56.290 correct we have an electronic air 00:11:57.72000:11:57.730 cleaner yes we do we have a in Florida 00:12:00.72000:12:00.730 you use would return plenums right nor a 00:12:05.34000:12:05.350 return box as you call it and we have 00:12:08.60000:12:08.610 our supply going at the top and our 00:12:11.64000:12:11.650 return coming back here yes we do all 00:12:13.47000:12:13.480 right so let's take a look what's inside 00:12:14.61000:12:14.620 that looks a lot cleaner than the last 00:12:16.44000:12:16.450 ones kill yes I bet us this one gets 00:12:19.20000:12:19.210 maintained least once the lungs are 00:12:21.03000:12:21.040 feeling better already actually there we 00:12:25.11000:12:25.120 go aha so one thing I noticed right off 00:12:31.41000:12:31.420 the bat is that this evaporator coil the 00:12:34.02000:12:34.030 cold coil is in an a shape correct 00:12:36.33000:12:36.340 that's an a coil in this one all right 00:12:38.34000:12:38.350 and what's the advantage of having an a 00:12:40.62000:12:40.630 shape instead of what it gives you 00:12:42.42000:12:42.430 gives you two sides for the air to flow 00:12:44.91000:12:44.920 across which helps with pulling moisture 00:12:48.24000:12:48.250 out of the air by having the two sides 00:12:51.00000:12:51.010 for the air to go across rather than 00:12:52.11000:12:52.120 just the one and there's more cold 00:12:54.00000:12:54.010 surface for the air to contact correct 00:12:56.31000:12:56.320 to get cool just like there's more air 00:12:58.23000:12:58.240 surface outside for the heat to escape 00:13:00.90000:13:00.910 yes okay so we've got to match the the 00:13:03.75000:13:03.760 interior evaporator coil with a 00:13:05.61000:13:05.620 condenser coil outside right yes we do 00:13:08.01000:13:08.020 okay so and then we have a variable 00:13:12.81000:13:12.820 speed blower here yes yes this is a 00:13:14.87000:13:14.880 variable speed unit what this allows you 00:13:17.91000:13:17.920 to do is for humidity control it can 00:13:19.98000:13:19.990 lower the speed of the air as it draws 00:13:22.11000:13:22.120 it across the coil to draw more air out 00:13:23.79000:13:23.800 of it out of the more water out of the 00:13:25.92000:13:25.930 air alright so in order to get water out 00:13:29.31000:13:29.320 of the air we have to cool the air 00:13:30.57000:13:30.580 correct and we have what's called 00:13:32.61000:13:32.620 residence time right worthy how much 00:13:35.22000:13:35.230 time is the warm humid air in contact 00:13:37.92000:13:37.930 with cold surfaces and the longer the 00:13:40.92000:13:40.930 amount of time it's in contact with it 00:13:43.23000:13:43.240 the more water it's going to condense on 00:13:46.82900:13:46.839 those coils correct 00:13:47.97000:13:47.980 all right so and a variable speed motor 00:13:50.37000:13:50.380 also will just run if you only need a 00:13:53.51900:13:53.529 little bit of cool air if it's not so 00:13:56.06000:13:56.070 hot out right it'll run low run at a 00:13:58.98000:13:58.990 lower speed okay all right pushes like 00:14:00.96000:14:00.970 you say it less CFM through the house 00:14:03.29000:14:03.300 providing you only what's required to 00:14:05.55000:14:05.560 cool the home instead of just an on and 00:14:07.74000:14:07.750 off right so if we didn't have a 00:14:10.14000:14:10.150 variable speed motor when the air 00:14:12.75000:14:12.760 conditioning came on it would go didn't 00:14:15.81000:14:15.820 stop I was out and with a variable speed 00:14:18.32900:14:18.339 it ramps up slowly it does and then 00:14:21.30000:14:21.310 comes down slowly getting all the cool 00:14:23.37000:14:23.380 air out of the ductwork that's exactly 00:14:25.19900:14:25.209 what it does okay so then our experience 00:14:27.66000:14:27.670 in the house is less drafts and more 00:14:30.30000:14:30.310 comfort for us yes 00:14:31.80000:14:31.810 all right so how about this electronic 00:14:34.38000:14:34.390 air cleaner what this does is it 00:14:36.48000:14:36.490 provides you with a couple of things it 00:14:39.84000:14:39.850 provides you with better filtration and 00:14:41.57900:14:41.589 a standard you know through the wall 00:14:43.71000:14:43.720 return it's four inches thick so it has 00:14:48.18000:14:48.190 much more contact surface for air 00:14:50.19000:14:50.200 particles to go through okay so that if 00:14:52.31900:14:52.329 it doesn't Peck get it on the first pass 00:14:53.64000:14:53.650 I mean it has more room to get through 00:14:55.17000:14:55.180 also 00:14:56.46000:14:56.470 it has being electronic it has a thin 00:15:00.24000:15:00.250 wire runs crosser that's electronically 00:15:01.95000:15:01.960 charged and it helps capture viruses and 00:15:05.82000:15:05.830 other things to there and over time by 00:15:08.25000:15:08.260 sitting on electronically charged wire 00:15:09.87000:15:09.880 it will actually kill them so that you 00:15:12.30000:15:12.310 don't pass through these allergens and 00:15:15.51000:15:15.520 other colds and viruses and things 00:15:17.55000:15:17.560 through the house to others and help 00:15:18.96000:15:18.970 keeping you a little bit healthier very 00:15:20.61000:15:20.620 good and so here's our return duck we 00:15:23.67000:15:23.680 return trunk our return plenum and then 00:15:27.09000:15:27.100 we're cleaning the air before it goes 00:15:29.19000:15:29.200 through the evaporator coil so that we 00:15:31.50000:15:31.510 don't get dirt clogging up all these 00:15:33.36000:15:33.370 little fins here right so the key is 00:15:35.67000:15:35.680 keep it clean and well how many seer is 00:15:39.33000:15:39.340 this unit uh this unit should be about a 00:15:42.39000:15:42.400 17 seer unit 17 seer and it's several 00:15:46.05000:15:46.060 years old this is about two years old 00:15:48.03000:15:48.040 okay um it's been running for a few 00:15:50.28000:15:50.290 years as you can see like any unit I 00:15:52.38000:15:52.390 mean you have water so you're going to 00:15:53.67000:15:53.680 have a little bit of rust and things 00:15:55.89000:15:55.900 clogged across the metal you can't help 00:15:57.66000:15:57.670 that but I don't see any dirt no sir 00:15:59.61000:15:59.620 maintained oh so now so now Kelly this 00:16:02.19000:16:02.200 is something that's important for people 00:16:04.89000:16:04.900 to know is that the cost of air 00:16:07.35000:16:07.360 conditioning our house is kind of like 00:16:09.84000:16:09.850 an iceberg yes and the part above the 00:16:12.93000:16:12.940 waterline we all know that the you know 00:16:14.55000:16:14.560 iceberg only 10% of the iceberg is above 00:16:16.59000:16:16.600 the waterline and that's the cost of the 00:16:19.32000:16:19.330 equipment itself right and the whole big 00:16:21.84000:16:21.850 part below the waterline is the amount 00:16:24.75000:16:24.760 of electricity that we're using through 00:16:28.02000:16:28.030 this equipment over the life of the 00:16:29.46000:16:29.470 equipment that is correct so with high 00:16:31.80000:16:31.810 efficiency equipment we can cut the our 00:16:34.80000:16:34.810 cost over the long term of that big part 00:16:37.98000:16:37.990 below the waterline if we'll just spend 00:16:39.69000:16:39.700 a little bit more on the equipment when 00:16:41.88000:16:41.890 we're buying air conditioning yes it's 00:16:43.89000:16:43.900 very beneficial to do that like you say 00:16:46.29000:16:46.300 over time it is upfront cost but over 00:16:49.20000:16:49.210 time it just it with the variable speeds 00:16:51.03000:16:51.040 the two stages you will cut the bottom 00:16:53.43000:16:53.440 at iceberg in half sometimes yes and 00:16:55.59000:16:55.600 especially compared to the low 00:16:57.48000:16:57.490 efficiency one we just looked at boy so 00:16:59.82000:16:59.830 if you're shopping around for air 00:17:02.10000:17:02.110 conditioning or heating for that matter 00:17:04.07900:17:04.089 and we're going to take the lowest 00:17:06.12000:17:06.130 bidder we're going to get the lowest 00:17:07.35000:17:07.360 price you know we're going to get a low 00:17:09.55900:17:09.569 efficiency unit urine and we're going to 00:17:11.36000:17:11.370 just continue to have higher monthly 00:17:13.03900:17:13.049 bills as a result correct so it's not 00:17:15.82900:17:15.839 wise to look for the lowest price when 00:17:18.76900:17:18.779 you're shopping for air conditioning and 00:17:21.40900:17:21.419 heating spend it spend more get the very 00:17:25.06900:17:25.079 highest efficiency that you can get in 00:17:27.74000:17:27.750 heating or air conditioning and you will 00:17:31.31000:17:31.320 save money in long run you will and 00:17:33.20000:17:33.210 actually sometimes the not so long run 00:17:34.99900:17:35.009 yeah like you say it's just varies 00:17:36.79900:17:36.809 depending on a fish see the unit the 00:17:38.57000:17:38.580 higher the fish see the more you'll save 00:17:40.24900:17:40.259 so it takes less time to pay it back 00:17:41.84000:17:41.850 well Kelly I think it's been fascinating 00:17:43.54900:17:43.559 looking at the actual equipment between 00:17:45.61900:17:45.629 low efficiency and poorly maintained 00:17:49.12900:17:49.139 equipment compared to high efficiency 00:17:50.86900:17:50.879 equipment I appreciate it and wish you 00:17:53.96000:17:53.970 best of luck here in Florida thank you 00:17:55.51900:17:55.529 sir
