How to charge your Mini Split with 410a Refrigerant

R410A is not charged as a liquid because it's faster. It because when charged as a gas, it fractionalizes and you end up with two refrigerants instead of a blend.
A device called a Quick Charge will allow you to charge as a gas on the suction side, bur the bottle still has to be turned upside down.

Using a cheap pair of channel locks priceless.

If you didn't use any sealing treatment on the line connections (both ends, both lines) it's pretty much a guaranteed leak. I use Nylog Blue which from what I've heard is one of the best on the marked. The very first one I put in I didn't use the Nylog, even though I made sure to really tighten the lines 2 years later it was low on gas. I went back and resealed the lines with Nylog no problems since or with any other systems I've installed.

Believe it or not, the Schrader valve, where the hose hooks up to charge, leaks. It’s always good practice to check for leaks there after hooking up lines to charge. Spray some soapy water or give it the ole spit test before capping..

[robertcherry]

Where do you get these guys? You do not charge R410A as a vapor. Blends need to be charged as a liquid to prevent fractionation. Blends have different refrigerants that have different saturation points.They have a saturation range instead of point.the more volatile refrigerant will boil off first, therefore changing the percentage/composition of refrigerant…. Understand??

A customer that hovers over you is the most annoying experience for a tech.

Just so you have a good outcome always remember to let the refrigerant in slowly . Just a little bit at a time . That way you don't hurt your compressor. Always good to use torque wrench on your service port caps. This is just in case a Schrader valve fails. This also applies to the other caps such as your valve port caps. Proper tools will also save your butt in the long run and hope this helps

Thanks for the tip really appreciate it so far. This one’s been working great thank you for watching.

First thing he should have done is to check for leak, do a leak test sense there was some Freon in the system , then if don't want to go deep he should pump in a die in and complete the charge, next time need a charge or a day or tow later go back and test for leak with sniffer and light leak tester that will show the leaky spot in green or red depending the collar of the die leak test you pumped in .

ATF has the best anti-corrosive components you'll find anywhere and it's made specifically for the newer aluminum transmissions used today. Any brand is perfect. It'll put an end to your coil fins getting gunked up in that environment, no doubt about it.

If you have a refrigerant problem - you might want to check the flare fittings behind the inside unit

If you've ever installed one - you probably remember how tough it was to hook up the lines while mounting the unit (unless they were connected before, pipes wrapped and the entire length fed through the wall). I was also gunshy about bending the pipes and kinking them - it put me off of wanting to tighten them too much but needs to be at the proper torque

Guy tore up ur fittin with the channel lock

[TomLeeman]

Thanks I appreciate that info and thanks for watching

[skypros]

The thing I noticed was he did not purge the Blue line with So did the unit get a full blue line of oxygen ?

[MalcolmJack-dd]

Need to add freon slowly it's a vapor compressor if liquid add too fast you will overcharge it and possibly damage the compressor

FYI, that extra length of tubing that is rolled up behind the condenser should be layed horizontally and not vertically. Refrigerant can settle in the low spots of the tubing

It is good to keep in mind that this guy is NOT GIVaING A TUTORIAL. He is being filmed and asked questionS with an interested home owner. The cheap shots and the derrogatory comment do not serve anyone!! Keep it real guys, you have also use the channel locks backwards more than once.... You guys with the tips and suggestion... Now that is good content!. Cheers

Who is the AC guy? I live in Pompano Beach and need a decent minisplit guy.

[richardreyes]

Does the unit need to be running while one is checking the refrigerant level and adding refrigerant? Also, should one evacuate the unit first and again, should the unit be on or off? Thanks.

[matthewnovik]

where does one buy cheaper r410a? can you use other refrigerant? ex: r134?
