IMPORTANT NOTE: You need to purge a little refrigerant through the hose connected to the refrigerant tank *before* connecting to your gauges. You do *not* want to get any air into the system! If you don’t purge the hose, you’ll inject all the air in it into the system.

I am grateful for these videos. I'm a widow in N.Ca. and the contractors are constantly trying to gouge me. For a single ductless minisplit (21-24seer 18-21 btu) unit I've been quoted 6000-10,000. Costco has a mrcool 21seer/18but for $1,500 now I need to get a friend to help me install. I already had the electrician (his bid for a lot of work was 3.8K where most bids are at 7-10K for electrical work) install the 240/40amp circuit & outlet.

Thank you so much for your video I tried it on my Senville two air handler mini split. Aura model 18000btu. It worked like a charm but only after the third try. I must stress to everyone please bleed the lines. Make sure the air conditioner is running when you’re hitting this psi Mark. Again bleed the lines, bleed the lines on the gauges. If you ever have trouble DM me. I can explain to you in detail what I did. I don’t make KZfaq videos much at all. My leaks were s result of loose connections. All my refrigerant leaked out so I charged it from empty. Lord bless.

Multizone senville minisplit. Had a leak and will be removing all the remaining (likely very little left in the system). Removing it by using an evacuation pump into a separate cylinder. This will remove 410A from the compressor as well all line sets. Note: This multizone system has a manifold with a set of “king valves” at the top of it. One king valve for the vapour line and one king valve for the liquid line. The vapour line king valve has a 5/16” port on it. These king valves are the separation from the compressor behind the manifold and the rest of the system. Lower on that manifold are the line sets and each line set zone has“service valves” that when opened, allow flow thru to each connected line set. So, the king valves AND the service valves are open during the evacuation step noted above. After that, pressure test with nitrogen and locate /repair any leaks. Vacuum test down to 200 microns and confirm it holds it there. At that point, the system is tight and ready for fresh unused 410A to be added. My system factory charge calls for just under 6 pounds, according to the label on the side of the unit. My question is…do I close the king valves and add into one of the line set’s suction port as it is weighed in…and will the line sets hold all the 6 pounds of 410A, then open the king valves which then the 410A will make it to the compressor and I then start the unit up to circulate all thru? The last step and if the king valves should be open or closed during all the steps is what I am unclear about. Very much appreciate if you can enlighten me on this. Thank you…

Thank you for the video. My 410a was delivered today and I just got done recharging my 24k BTU Mr Cool. PSI was at 75 and wouldn’t get my garage below 80. It was basically blowing warm air. Turned the AC to 73 and went outside to recharge it. Took about 5 min, As soon as I walked into the garage I could feel the cold air again.. Since I installed the split system myself I had all the tools already. $75 for a bottle of 410a is way better than $500 for a service tech to do it.

Glad to help. However, you may have a really small, slow leak if you need recharge every two years, and should try to find out where the source is. It may be at the ends. Try this, it works extremely well, and use it when you have to add refrigerant again, and you may never have to add refrigerant, as it's a closed loop system.... amzn.to/3edDJsX

Great video 👍 My multizone minisplit lost most of its 410A. Repaired the leak and will fully evacuate what may be left in the entire system including the compressor. Pressure test with nitrogen/ then vacuum down to 200 microns and hold/ once that is done, I will add just under 6 pou ds of fresh 410A via one of the line sets. Question: Do the king valves (these are not the line set service valves but are at the top of the multiple zone manifold) need to be closed and then opened only after the line sets have taken the 6 pounds or are the to be open while adding? Not sure if the two line sets (less than 50’) can hold all the 410A. At what point is the system turned on? I dont think it should be running while initially no 410 is in the lines.

Purging........ On the yellow hose, 1-connect to tank, and gauges. Slowly open the valve on the REFRIGERANT tank as to slowly release some refrigerant 2-On the gauges, slowly unscrew yellow hose at manifold until you hear air out, should just take a second. Quickly tighten. On the blue (suction) hose, 1-Fully tighten hose on the HVAC unit, and on the gauges. 2-Slowly loosen connection on manifold, the remnants of air in the line will bleed out at the connection to the gauges, (you will hear the sound of air coming out) at the manifold connection, and you can quickly tighten immediately after. It is a split second thing!

Please bare with me as Im not a HVAC tech. Here goes. I just purchased a LG 22000 btu 1 zone mini split system. The unit comes pre-charged for a 25 foot line set, but I need a 35 foot line set to reach my living room,so I purchased one.. I believe after watching your 2 videos I would do this.....1) Install the system with the 35 foot line set. 2) Vacuum out the line set down to -30psi , wait a while and check for pressure leaks. If there are no leaks, my next step 3) would be to release the R410A which came pre-charged in the unit into the system. 4) Then I would check the pressure in the line set with the vacuum gauge to see what the psi is and then add as much R410A..... which I would have to purchase separately, to get it to between 117psi and 120psi.. Im pretty sure there is no need to purge the system. Does this procedure sound correct....thanks PS the manual says to add 0.38 oz/ft. So that should be about 3.80 lbs.

Yes, sounds like you should be fine. It will be very critical, to use the sealer, amzn.to/367xEf2 to ensure no leaks at the connections. Hope you have your refrigerant already. Ebay seems to still have it, but there's an industry push to eliminate sales on the web. You can get 11 pounds for $107 delivered to your door, and that's not bad considering retail market prices.... rover.ebay.com/rover/1/711-53200-19255-0/1?ff3=4&pub=5575339965&toolid=10001&campid=5338199104&customid=&mpre=https%3A%2F%2Fwww.ebay.com%2Fitm%2FR410a-R-410a-R-410a-Refrigerant-11lb-tank-New-Factory-Sealed%2F202661144956%3Fhash%3Ditem2f2f8ba97c%253Ag%253Au0YAAOSwz4Zc%257Er2V%253Asc%253AFedExHomeDelivery%252133990%2521US%2521-1%26LH_BIN%3D1

Failed recharge. sigh. I recently installed a new Senville 18K btu unit. Did a 1.5 hr vacuum test, no problem. Finished setup and started the system running. (note: It's winter!) It started heating just fine. Then I got a call and had to leave for six hours. Came back - and it wasn't heating anymore. Turned it off, and checked the Freon pressure. it was 0. Apparently the system developed a nasty leak somewhere. Since I had shortened the lineset (I only need about 20'), I assumed my flaring job wasn't good enough. Due to shipping snafus, I had a spare lineset (25'), so I just replaced my shortened one with a factory built one (and looped it). Since I had to wait for the Freon to arrive, I did a VERY LONG (4 day) vacuum test. It held vacuum. It's 36 deg F outside. Since there was no freon and I didn't want to run the compressor when empty, I did a slow fill to 100psi. Then powered up the system, and was able to fill it to 115psi. Wouldn't go higher. (freon too cold??) Yes, it's in Cooling mode - as I do have an alternate heat source in the house. Let it run for 15 minutes - no cooling, blower running inside, the fan on the outside unit is NOT running, but I can hear the compressor running. Pressure hasn't changed. Tried flipping it to Heat mode, and waited 15 minutes. No heating inside, inside blower running, outside fan and compressor running. No heat. Pressure hasn't changed. Gave up and shut it all down. Any suggestions?

Did you open the valves from the compressor to the lines? Towards the beginning of the video, he said don't try and add refrigerant to these ports. Ask me why I know? Been there, done that. Once you have the lines all connected, take the caps off and open the valves on both the high and low, you should hear a hissing sound as the preloaded refrigerant goes from the compressor to the lines. Open the valves all the way until the stop and then see if you get the heating and cooling desired. This is somewhat off the top of my head recalling from a couple of years ago, but I think there was also set of a master valves on top of the individual ports on my unit as well, so you might want to check that as well.

Thank you for for sharing . The best practice for mini split is to start from zero ... Pull the vacuum and add refrigerant by weight. Anyway, I also top up my 9000 BTU gree inverter.. During topping up, I keep monitoring psi on the gauge, current from the clamp meter , temperature on suction line , temperature from supply vs return air on evap unit. I turn my ac to turbo mode or max cool... run for a while ...and adding refrigerant... My sweet spot Gauge psi.. 125-130 Current getting close to RLA (it is ok for mini split to ramp up to RLA on turbo mode... We are not gonna keep using turbo mode all the time in real life, right?... The current will go down when on normal operation. Super-Heat keeps fluctuating in the range of 5 +-3, which is normal Delta T or return air temp minus supply air temp on the evap indoor unit is between 15-20 degreeF

Thanks for the tutorial! The AC guy told me that the freon is 1-2 lbs lower than normal two weeks ago. I followed your instruction and made sure all the hoses were securely connected. However, the gauge shows a low side pressure of 0 (the AC is running fine). But it stayed at 210 psi when I release the refrigerant into the unit (is it the tank's pressure?) Do I need to open the service value to get the pressure readings?

I found pressure to be really unreliable on a mini split, especially if it's something with an electronic expansion valve, as they will adjust both the subcooling and superheat on the fly for optimal condition... Mine doesn't have electronic expansion valves, just capillary tubes, but I did it by pressure and feels like I might have overcharged it, as the compressor started becoming harder and harder to start, and dropping the charge (recovering refrigerants) fixed it. When this is done, the AC is cooling better but also the compressor hard start problem disappeared. However on the R22 system the pressure is reading to around 40 psi (which corresponds to a saturation temperature of about -10C), and it would never go above that, but any attempt to try and go over that either resulted in weakening the compressor or even seizing it up. I think saturation temperature adjusts itself based on various operating conditions as well as fan speed (you really want a ton of airflow over the evaporator to get accurate reading). If you look inside a mini split condenser there's a capillary tube leading from the condenser coil before it comes out to the valves. I do not know why this exists but there is likely a reason for it. This does not exist in standard AC units with a TXV. I know some even do it by current draw, but again, it seems unreliable. Weight seems to be the most accurate way to do it. It feels like a mini split needs to be completely recovered and then have the charge weighted out.

Yes, I got the sniffer and await the arrival tuesday of the 410a (5 lb can) I also ordered the flare washers, though I also have the nylog blue(my first thought) and a good husky flare tool if needed. . My HVAC guy said I could just pull a vacume (then change out the yellow tube from the vacume pump to the refrigerant, purging that line as per you, and then it would pull the 2.65 pounds(I have a scale to get exact amount though likely to lose a bit in the hose and the dissconnect process) in without running it (with the refrigerant upside down of course), much like the original release on initial install. If I pull a vacume, I will be unable to purge the blue line(with refrigerant) as it will be holding that vacume (valve closed after using the vacume pump).I suppose I could do all this with the vacume and the unit off as per HVAC guy, and then do your method of "sucking it in" via running it on cool if the vacume does not suck it in . My plan was to seal the joints at the lower unit, particularily the 1/4' line that seem to have oil around it, fill up the unit and check all the joints with soapy water and my sniffer as well as inside the coil in the air handler and other wise see if it hold pressure over time. Hopefully it is not the coil outside and I could sniff that out..

Just had a big snow storm up here in CT so it will be a while before I can run it in AC, but the system has had that water running sound along with gassing sounds after cycling off. Fwiw, its been doing that since I sucked it down, released the precharge and started using it last summer. No leaks according to nitrogen test or electronic leak detector since then.

@@Celohyoudee For future reference, that is DESIGN pressure, meaning the pressure that the system can safely withstand before catastrophically rupturing somewhere. Design pressure is NOT the normal operating pressure of the gas. Operating pressure will be lower. Manufacturers do not specify operating pressure because there are too many variables. That's why they specify charge weight.

When the fan is running the pressure is at 120 and when the fan stops the pressure is at 68. I’m still getting the CH 35 error code for low pressure when running the unit. The pressure doesn’t seem to be changing. Any advice? Thank you

CH35 means you are seeing the low pressure sensor error. This error can be caused by any of the following causes: Overload operation (outdoor fan constraint, screened, blocked) Refrigerant leakage (insufficient) Bad connection of the pressure sensor Bad compressor sensor Bad PCBA You should check for any leakage, or if there are any blockages on the unit. If you are still not able to fix it, we recommend a local contractor to have it diagnosed. lghvac.com/professional-locators/contractor-locator/.

All valves closed except the blue one. Best practice is to vacuum out the lines, done before video). Weight the refrigerant on a scale, according to what the label on your unit says, Example, 1.5 pounds. Slowly, open the blue valve, and let the unit run on cool, and open the blue valve and allow some refrigerant, and let the unit stabilize for 15 minutes. Adding refrigerant is a step that requires patience, and the proper tools. Unfortunately not many have either, lol.
