How to Check AC Freon Level No TOOLS

what's up everybody i know most of you don't have one of that or whatever that it's not easy for you to tell if you have enough refrigerant in your system so today i'm going to show you three cool tricks how to tell if you have enough refrigerant in your ac thank you for watching and please subscribe because one of our subscribers will be getting this honey honeywell honeywell wifi thermostat for our next month's giveaway we're going to do is uh pretty much you're going to feel the temperature coming out with the condenser this will put your hands up in the fuel the air and what it is like you're going to feel around 10 to 15 degrees than normal temperature if you see any cold spots like in certain spots like right over here it's not too much it's kind of colder than the rest of the area you're definitely seeing some refrigerant uh this test is you cannot tell how much percentage wise uh exactly but you can still know if you all that it's pretty much coming with a harder temperature so the second test we're going to do is like uh we're still going to be outside unit and what we're looking for is the return pipe the return copper pipe that's between the units and uh you can locate it right over here we had a liquid pipe and then we got a return vapor pipe and what we're looking for is the temperature of that particular pipe sometimes you can see it visually uh every time the pipe is sweaty uh you can see some moisture condensation on it it's pretty much a good sign of kind of 95 of refrigerant level to be okay if that pipe is missing moisture like in our case uh i see it's colder but it's not a cold it's probably around 70 degrees that's mean you're missing some refrigerant uh i'll say uh 25 at least having if do that pipe uh it's frosted all around it that's mean you having definitely issues either with the restriction somewhere in the pipe or the refrigerant levels are definitely low and one more thing if you have actually two units outside you can compare the readings from one to another so here what we have is like uh the temperature gauge on one side and we got uh the temperature reader and uh we've got the second site right there and uh it's definitely showing a lot of difference as you can see the temperature of 80 degrees it's on one side and the other one is like a 60s so now i'm going to show you your third test and we're inside the house and doesn't matter uh if you have your vents up there or on the floor it doesn't matter which way you got what we're going to do is like uh we're going to use a temperature gauge you can use any 10 thermometer i'm using infrared it's like 25 dollars and you're going to see the link down below if you want to purchase one it's a cheap harbor freight one but still does work and what we're looking for is the temperature that's coming out of the the air coming out of the vent what we're seeing is like a if you have a temperature uh that's around 14 degrees and over 14 18 degrees difference between the room temperature and the vent that's mean your systems most likely have plenty of refrigerant i'll say 95 if your refrigerant if your temperature the delta the difference between the two temperatures uh less than 14 i'll say 10 to 14 degrees you're missing around 20 at least and if the temperature the delta it's uh more than that i mean uh less than 10 degrees most likely missing around 40 to uh i'll say 20 to 50 percent so it's definitely need to get it checked out and what we're doing is like uh we need a ambient temperature so we're going to just pick the wall temperature and right now it's uh 75 degrees and we're going to measure the temperatures coming out of the so what i have is uh 65 degrees so most likely uh in a 10 degree difference 10 uh degree delta and most likely we're going to be missing some refrigerant and now suspect because outside was showing like 20 and now we're seeing uh around only 10 degrees i'll say most likely 30 percent 30 to 40 most likely and stick around i'm going to show you a cool trick how to tell how many pounds or ounces i'll say you're missing of your refrigerant without even putting the gauges on so to recap just uh in the first part what we're doing is we're just checking to make sure we get some cooling done the compressor is working and you can feel some heat coming out of the outside unit in a second test what we're looking for is a condensation on the return pipe and if the no condensation you can check the temperature just to verify it's in the correct range in the third test we're trying to find the difference between the room temperature and the temperature of the cold air coming from the vent in our case uh we find out the delta is only 10 degrees so probably we estimated that we're missing 30 to 40 percent so once you know approximately what percentage refrigerant you're missing here's the easy way to turn it into a pound try to locate identification label on the outside unit similar to there that can find the amount of refrigerant and also the type of refrigerant in our case we guesstimated that we are 30 to 40 percent low so in 66 ounces in this case we probably expecting to have 20 to 27 ounces added to top it off oh that's most likely one to two pounds in the second example we're working with the r410 and the system uses approximately seven pounds so in this case if we have a thirty to forty percent missing we expect to have thirty or three to forty five ounces added oh that's approximate two to three pounds that like button if you like this video
