How to Properly Recharge Your AC System

[@KodaGTF]

I got my first car (scion xa 2005) about 7 years ago and the A/C didn't work along with various other issues. The mechanic wanted about 3k to fix the problem (it did have a small leak somewhere, and they said I needed to replace a bunch of parts to fix it) which was almost what I paid for the car at the time. After doing this it worked until a month ago, so I followed this video again and it's still working! With your videos I've helped myself, friends and coworkers fix suspension, brakes, oil pans, alternators, fluids, door handles/other body parts, scratch repair ect. I basically ask them to pay for whatever tools/parts are needed so they're still saving a bunch and I now have a respectable selection of tools! Between the confidence your videos give me and the ease of repair for my car I've saved untold amounts of money, thank you!

Hi Chris, I owned an automotive air conditioning and radiator service shop for about 30 years. We have charged thousands of vehicles. You did a very good job of explaining how to charge an air conditioner. I have always been extra careful to bleed the air out of the hose/s like you showed. I open the shop in 1973 and sold the business to an employee in 2002 and worked for him a short time. The business is still open today.

Hey Mr Fix, I want to say thank you very much for your videos. I am an OTR ( Over The Road ) truck driver and had an A/C compressor fail. It was most like caused because of boss not pulling a vacuum on the system. I have beat my head against the wall trying to explain why this is an important step, even sent him your video to NO PREVAIL.

I got home and checked my condenser and sure enough there was a huge dent in the condenser and spray residue of AC oil everywhere. Now I'm waiting for my condenser (only $62) from Rockauto to arrive this week.

Assuming the refrigerant leaked out through the hole/leak in the condenser. 1) Once I replace the condenser, what do you do if you still see pressure on the gauges? Did you see any remaining pressure after replacing condenser? 2) Did you still add oil, or just assume the compressor still had oil? Or should you still add oil for the new condenser you put in?

​@@BizyBeee I think you still have to replace some oil with any part replace. Also supposed to replace things like the filter dryer and the strainers/etc. sometimes even flushing the system is a good idea But yeah I think you'll want to add some oil, I just don't know how much You shouldn't see any pressure when the condenser is removed, and the system should be emptied by someone who has a machine to recover it.

[@jimlechner8526]

Nice videos Chris! As a (EXTRA) precaution after pulling a vacuum on a car's a/c system and after performing a system leak check for a minimum of the 30 minutes (using a R-134A manifold gauge set ONLY) and BEFORE disconnecting the manifold gauge line set: CLOSE the HIGH & LOW valve at each port, then wait another 15-30 minutes to verify that the High & Low side a/c port needle valves (a.k.a.- Schrader valves) are not leaking. Nothing's more irritating than having a charged a/c system leak at the High or Low side port, immediately after disconnecting the high & Low side line set!

[@thetruthserum2816]

I thought this through, and I think there is a slight issue... So, let's say that the Schrader valve is leaking... Well, if it leaks into a manifold gauge that is completely sealed, then there is no leak at all (no delta)... Instead, I think one would have to close off the valves, bleed the gauges, then watch to see if they go from zero to some value while the Schrader valves are not depressed... Let me know if that is flawed thinking or not... Just realizing that a Schrader valve turned backwards is a blow off valve dependent on spring strength...

[@Worldsokayestcraftsman]

Dude this is one of the best how to videos I've ever seen on any subject. Well done! If I'm just disconnecting the condenser for a short time to do an engine swap i assume i wouldn't' have to add any oil, correct? Also if I tape off the open lines would I need to replace dryer and orifice tube?

Found it had a leak on the high side shrader valve using soap and water trick. Evac'ed the system, replaced shrader valve, vacuumed down the system for the 45-60 min, refilled with correct amount of refrigerant and the system is working great, blowing 40 degree F air again!

@@joseaponte8729 Just for other's benefit since I just did this and it's fresh on my mind: The high pressure (red) line has a valve at the gauge set. The low pressure (blue) line has a valve at the gauge set. If you open either one of these valves it opens a directly path to the yellow line immediately! You never open the valves on the gauges until you are doing a vacuum or filling refrigerant into the system! The ONLY valves you need to open to observe the pressures in the system are the valves on the AC line ends of your blue and red hoses.

[@matthewbaken7669]

I recommend replacing the Schrader valves at the high and low pressure ports. Those valves are prone to leaking o-rings after a while, and especially after a service, therefore it’s cheap insurance to just replace them. As one can see, bright green dye is visible in the ports on Chris’s high pressure port. That visible dye is indicative of a leaking schrader valve. The dye is added to refrigerant to help identify leaks on an automotive AC system.

[@BartSparrow123]

Dye also comes out a bit anytime you use your guages on the shrader valve, but I agree, they cost 50 cents each to replace!

An additional tip for car AC service: If your manifold gauge set isn't new (mine is inherited), check the condition of the rubber refrigerant hose seals. They can be replaced and should be replaced if they are old, compressed, hard, or otherwise deteriorated -- either that, or purchase a new hose set. Also, when storing the manifold gauge set, loosen the fittings a bit so the seals don't get compressed. Tighten them when you are ready to use them. Mine were so old, when I tried to remove the seals, they came out in hard, crumbly pieces.

You have to be the first guy I've seen on KZbin to actually do this job right, great demo, very informative and easy to follow. although just one tip, if changing to a brand new compressor and you need to add to oil, it's far better to tip the oil straight into the compressor rather than through your gauge lines, and then rotate the clutch on the compressor. That way when you first start the compressor it's properly lubricated and doesn't suffer any potential damage. But without a doubt a great tutorial

[@musclefixer]

Question. Should you purge the yellow hose again when disconnecting the first can, and attaching the second can?

[@strawboss59]

I had the same question. I've checked my dispenser gadget/valve that pierces the can and mine only is sealed closed in the "pierced" position. (when the tip has pierced the can's seal.)So screwing the new can back on to the gadget is fraught with danger as to have that valve closed/sealed also means the piercing tip is opening the new can before it is actually fully screwed down. So what I would do is after the first can has emptied would be to close the valve on the can first, then close both high & low pressure manifold valves on the gauge, THEN unscrew the empty can, open the valve fully so no danger of piercing the new can.....thread the new can on, THEN pierce the new can, purge/bleed the line as with the first can, then open the high & low pressure manifold valves....

[@robgautomotive]

Hey chris im a auto tech from Tx. Just wanted to mention the new ac cans have a saftey valve inserted and the Schrader valve itself wont pierce the can all the way down and wont release the r134a. Auto parts sells a 5$ adapter that goes under the valve.. Just thought id share with other DIY community.

[@PWgadgets]

You don't know what a schrader valve is as that's not what you are describing

[@SpicyBloodBean]

@@PWgadgets yes he does all the new cans are self sealing the have a schrader valve in the top of the can. this video is slightly incorrect as the can adapter needs to be screwed down in order to open the can. the pierce style fill adapters no longer work with the new cans

Great job as always! One minor point is that at 90F, according to AC standard chart, it requires 45 minimum on low and 250 minimum on high. You only got 40 and 200 PSI instead.

@@OxBlitzkriegxO You can't get an accurate weight. You have the weight of the green can piercing tool AND the yellow charge hose, sitting on the scale. Unless you remove the can from the tap and weight it. If you do that you loose gas/liquid so your weight is OFF. Very hard to get this proper by weight. What hurts us is these small 10oz cans. Our systems need more than one can. Changing cans and such you loose gas/liquid.

[@moparnutjim]

If you have a vacuum, just add the freon from the high side and the vacuum will pull the freon in. Most of the times I can get it all in with out ever cranking the vehicle. This prevents pushing the oil out of the compressor through the low side before the compressor starts pumping. I do this every day on a larger scale with Greyhound size tour buses. Some of them hold 45 lbs of freon and with a good vacuum I can get a whole 30 lb. can feon in from vacuum alone without ever starting the bus up.

[@SunsTo7]

Hi moparnutjim. I lost the charge and refrigerant by opening the low side port to atmosphere. Would there be any refrigerant left in the high side and if I pull a vacuum do I need to add any oil at this point?

[@Froggability]

Gary Bolinky. Yes you can, but it's likely to take air in simultaneously. So after sucking the oil in, start again on vacuum process, attach just to the low side otherwise much of your new oil heads for the vac pump.

[@GaelicDrummer1]

The best no BS training video on AC service ever! Thanks.

[@Froggability]

Main error I notice, at 8:05 attempting to add oil / dye? After vac and before adding gas? No. You'll never tip it down the hose in sufficient quantity OR without air getting in the yellow hose. The answer is 2 vacs. An initial vac assists in adding oil etc (if needed). Use vac to "suck" the oil up the hose. Then re-vac to 500 micron ensures no air in the system. Then add the gas. Better still add oil straight into compressor while it's on the ground. You can't do what he showed above without compromising the vac.

Fan needs to be on High and recirculate. Put temp guage in center vent. Put both cans in because of bleeding off both cans and removing both lines...plus whats left in the manifold guage lines...probably more than 2 ounces. The manifold guages and vent temp guage will let you know if system needs more/less refridgerant or is having a problem. The weight listed is more of a guide. Charge the first can upside down...second can upside down for half a can then leave upright for finish charging. The refrigerent will turn to a gas immediately when it reaches atmosphere/vacuum. Its only liquid under HIGH pressure.

[@fartbreath2884]

What about if you have cans of refrigerant from walmart (SuperTech brand) that are already pierced?

[@frequentlycynical642]

If your gauge set doesn't have a Freon bleed, just loosen the connection at the gauge set. I've never seen refrigerant/oil data on any of my cars. Good on Toyota! My latest AC repair required my official GM factory manuals to give me that information. I wonder why the valves on the port connectors are backwards in terms of closing an opening standards. Great video. I really appreciate the fast, accurate conversation w/o wandering, mumbling, trying again. It was a good refresher for me as I recharge a system tomorrow.

[@MrConspark]

Great advice for U.S. guys. Unfortunately in Aus, we need to be licensed under Ozone and Greenhouse gas regulations to even purchase this gas. Is probably why we repairers can sometimes get a bad rap for being expensive with our repairs. Cheers from Aus. P.S. A tip for replacing a compressor is to do an oil balance as per the warranty sheet with the new compressor, this will compensate for oil already in the system and will stop oil slugging the new compressor from too much oil in the system. Always replace the Filter dryer to remove any old oil/metal particles and moisture trapped in it.

[@MrMarkguth]

From Australia too, was thinking the same thing, and top ups are illegal, as you must have a leak in the system

[@MrConspark]

@@MrMarkguth Sometimes I find simple leaks like access caps missing and put that down to a leak, but yeah they make it hard for licenced repairers, if they do top ups. I depends on the customer and how much they want to pay.
