okay everyone thank you once again fortuning into our YouTube channel and the purpose of this video is if you haveinstalled a mini-split unit yourself or if you have bought one and it didn’tcome with enough refrigerant or maybe while you were putting in the flaredcopper lines on the inside and you had some refrigerant leak out of the systemjust like you see in this case here it’s starting to freeze up what you want todo first is you want to make sure that your refrigerant levels are up to parand what we’re going to do is connect this blue hose with these gauges on tothe connector down below now a standard connector like this one will not work soyou need to buy an adapter and that’s what we have here and I’ll post a linkon how you can get these as well but first you want to tighten it you want touse a little wrench make sure that it’s nice and tight and then you want to goahead and put this down at the bottom so we can get a reading so we’re going todo that next okay so as you can see down here I’vealready got my adapter in there and I made sure I tightened it well not onlyhere but here as well and what we’re gonna do is you open your low side andyou can tell if you’re doing this for the first time or you don’t know how totell it’s on your low side so some gauges will tell you low and high I meanthat’s as simple as it gets but it’s basically your blue hose you connect itto the access port don’t get confused with these two things here these arejust to open and close when you’re releasing the refrigerant so if you lookin there after you take these out you’ll see that you have a space for an Allenwrench that’s not for that for for what we’re doing here this is the part andyou’ll tell because if you were to remove this inside there’s like a littlepin that looks like a tire gauge it’s a straighter pal and that’s why you’regoing to connect your blue hose to so the sweet spot when you’re measuringyour psi down here you want it to be around the 117 120 range and you can seethis is about half so obviously it needs refrigerant so that’s how you can tellif your unit is not cooling very well or if you see some freezing like if you seesome freezing up here icing up and on the coils on the inside of your unitwhen you’re running in cooling mode that’s not a good sign so in this caseit obviously needs refrigerant so we’re going to go ahead and add it and to dothat we’re going to do another video and if you go ahead and click on the videothat will pop up on the screen it’ll take you straight to that so you can seehow we add refrigerant to it
Allright today I wanted to go over the five most common problems with air conditioners say you’re going to turn you’re air conditioner or heater on on cool or heat and the car and you lower your temperature down and let’s say nothing happens. The unit does not turn on the blower in turn at all first thing you want to check is the burners it can be a barrier breaker you often have a condenser breaker and then an offender to the fan himself these people here for the fan. So make sure your burners are oncoming dial. Sometimes if they do tripped they will travel halfway, and when you reset it you need the breaker to turn all the way off and then the crusher turns all the way back. Next thing to look at is the door switch Often there is a service by switch on the air conditioner heater unit it’s usually right here what you want to do is order press left to see if it will get that switch involved. So if you have it on heat or cool and motor already.There are many times what the problem will be Sometimes you may need to add a screw. Like this one a screws were added to make sure it was held in place. Or you can lock the tape from the door. If you add a screw you want to make sure the screw is not going to penetrate anything. Like any pipe or anything like that like a refrigerant hose behind it that you want to make sure you pick a spot which is good, and you don’t want a screw that is too long you don’t want to put it in anything it is not supposed to.Okay number three most common problem with air conditioners. So one we had Called an offender, two, the service by switch. The third most common cause of a non-working air conditioner Is open here when it comes to hatching sometimes Let’s say it is not unsafe it is this is like a mailbox bolt that Hooks the door in place and If that came open and it hatches fall open A lot of times that happens, your evaporator coil will freeze in a block of ice So, while you are there you are filtering and your filter makes sure you have a good air flow that a lot of the times that will happen are that will turn around a block of ice and you won’t even be able to pull the air filter off of it what you want to do is come over here to your thermostat and just turn cool down and just turn up the home fan so the fan turns up and down and put the switch down here in the way you can defrost the air conditioner and you also kind of want to look to make sure you condensation line does not overflow get built up with too much water from the ice melt something like that keep an eye on it, but keeping the fan up will help melt the ice faster and dry everything you know comes back to normal it take a while and ashes you will be able to put it to cool and motor again and you will close the door again and again if you need to you will add a screw or you can add some tape to make sure its held in place and do not open up to you again. Number four most common problem with HVAC heaters and air conditioners is a fan car that will not start. Often you can just replace the fan starts capacitor. I have a video showing you how to do it, “First thing to try” before you just walk out and the place of the car is to try to replace it the fan starts capacitor and it’s not really a start cap it’s actually a run cap but replace that capacitor that capacitor helps get the fan going And give it that initial kick to start without it can’t start it will just sitting there and humming and sometimes you can even start printing it with a pen or something you know “very careful” And the fifth most common cause of loss of your heating or air conditioning is a faulty thermostat so you can click on to my video on how to fix a faulty thermostat. In any case, these are the five most common problems with heating and air conditioning that you will come across what gives you call a new call or heat, and I have videos on everyone so you can check them out.I will try to fix the links here or correct on this video so you can Click on those to watch. And that’s it the five most common problems with the indoor side of HVAC heating and air conditioning. .
