Danny, thank you very much for putting these videos of the ac system up. I have been following you step by step for a complete ac system replacement on my son's 2008 Civic. Your videos are awesome and extremely helpful. I've used quite a few of your videos as I get this car in shape. Your videos have saved me approximately $1500 in dealer labor in the past few weeks! I only wish you had an Accord as I need to go through my 20013 Accord with 210,000 miles. That Accord has not had a single repair or replacement other than tires and battery so I have some work ahead.

Everything good, the bad step done in your video is to warn the viewers about the burn on the skin if the gas touches your skin as it did while you purge the air in the line. I did that following other video and i got the brown spots on my hands

[@SuperMan-uj7dh]

2013 Toyota Venza V6 my ac was cold, but not cold enough. I know theres no leaks because the AC still works just need some time to get cold. I evacuated and recharged by weight, and even adjusted for the freon in the lines (find the volume of pipe). The result? 100 degress outside, and almost immediately my AC blows 38 degrees. I also have a 2016 CRV, much newer but cannot blow this cold especially on a hot day!

3:16 mine stays stuck at -19 psi and loses the vacuum slowly. I have replaced both hoses and valves and the condenser is still good. What could be causing this?

[@MrSamPhoenix]

Did you ever figure it out?

[@Stonehopper1067HMG]

@@MrSamPhoenix turns out the front condenser had a hole in it. Replaced it and added the correct amount of AC oil. My AC gauges are inaccurate and need to be calibrated or replaced with a better set. It’s what happens when you deal with tools from Harbor Freight. So my AC manifold and hoses were fine, just the gauge is cheap and not as accurate. But a really good set can cost several hundred dollars. The HB set only cost $75.

Question, I need your help, before replacing, the compressor worked?, or this part help to active the compressor, because my car everything work, has Freon , relay replaced, still not work the compressor,

[@olenaerhardt7725]

@7:36 May I know what were the final readings on gages after everything done? I think it is important. I believe I've read somewhere (I think someone on Amazon wrote) that we can go not by the weight of the refrigerant added, but rather by readings on the gauges. In many films I see they put those cans w/refrigerant on scales. This part is a bit confusing to me. Thank you.

[@dannysdiygarage]

I don’t remember the final reading sorry

[@olenaerhardt7725]

@@dannysdiygarage That is O'k, thank you for reviewing my comment. Actually I think it might depend on a particular car. I found what those readings should be fm/Shop Manual (3 huge books) for the car (2001 Saturn SL2) I'm working on, they depend on temperature and humidity. The car requires 24oz of R-134a, so I think I'll go w/this amount, but keep eye on gauges, not to go over the limits for advised in the book pressure.

[@alanw5812]

about low 32psi and high about 220 psi, your air cond pump older may need more gas, some models new pump only need 22psi. use scale, because every cars gas have there own quantity, is old school, exe if this air cond still have problem like block somewhere, put this quantity will damage the system!

[@olenaerhardt7725]

@@alanw5812 Thank you for the detailed explanations. I fixed out 2001 Saturn SL2 HVAC system and it works great, but it is always good to know more details.

[@robertlewis3752]

Hi Danny how were you able to measure the exact amount of freon? Considering that you had 2 12oz can and the system called for 14oz

[@dannysdiygarage]

Great question, I added slowly the 1st can which should be 12oz, then I monitored the outlet middle vent while slowly adding more Freon from the second can until it reached its lowest temperature reading, when you add more Freon and the temperature starts to climb stop, and that’s the amount, I used a full can and approx 6oz out of the other, which is normal because some Freon is left in the 1st can and some was left in the hose, if you have a scale, that would be best Hopefully I explained this correctly

[@seabass22]

@@dannysdiygarageI read it takes 17-19 oz. So would make sense you added another 6 oz. Mine drops down to 39 F on the road. Think I’m good or should it be lower? It was over 90 degrees outside.

The temperature will probably only go higher from there, 39 is exceptional, stop, you’re good

What is the purpose of the “H” line? Is it only opened when purging the system of air and moisture? Newbie to AC systems here!

[@dannysdiygarage]

High side and low side readings helps determine proper balance of Freon or pressure, most cars are charged by the low side

[@jasonpeachrick2037]

⁠@@dannysdiygarage Thanks Danny. Another question: when you evacuated the old freon, how did you collect it? I want to do this entire procedure on my 1996 Camry, but the collection of the old R134a intimidates and confuses me… Edit: I want to add that out of all of the videos on KZbin that I have watched on performing this job, yours is the easiest to understand!

[@lendondattoo5566]

In total ,how long did the job take, 1 day or two? Good job, very good video capture of all essential elements to do the job. I am thinking of attempting this to replace the evaporator as I believe it is leaking.

[@dannysdiygarage]

To replace the expansion valve, if you go slow it should take 4 hours, it took me about 7 with filming, recharging the system 2 to 3 hours due to filming. Hope this helps, if I did it again, probably 4 hours start to finish

[@LT11859]

I have 2007 civic hybrid and I’m replacing the evaporator, expansion valve, condenser, and compressor. How much oil should I put and where to put it? And when recharging with Freon, do have the ac on high(blower)? Thanks!

[@seabass22]

AC on high. You should be able to look up the amount of oil for each component and add it to the component when you install.

[@troyhenry3267]

Danny, I want to just vacuum and top off or add any refrigerant to my 2010 Accord that I may be low on. So, if I haven't replaced a component and my system has freon already in it, then what would my procedure be then? There are no leaks, and it blows fairly cold, however, like you, I want to get my temperature as low and cold as possible. Any advice appreciated,

[@dannysdiygarage]

Over the years your ac system can develop a small leak and not cool as good as it could, unless you own ac machine that will properly remove recycle and evacuate the system, you’ll be limited to adding Freon, monitoring the air ducts temperature while adding a little Freon can help, just don’t add to much, go slow, you can always add more, check out this video at around 10 minutes kzbin.info/www/bejne/jZOzeImchs90i5osi=HI_inFKT_7lgxU94 Good luck, buy Freon with die and never buy anything that says it will seal leaks, I should have a link for Freon in one of my ac videos description

[@fernandoherrera6410]

Hi Danny hopefully you see my comment I have a 2005 Jeep grand Cherokee I was not having any reading so I replaced the compressor and clean the system no leaks now I have static pressure I add Freon when I am adding Freon everything looks good but once it stop. Low pressure drops negative and high pressure stays on static even though compressor is running. What can it be? Thank you

Sounds like a possibility of blockage

Sir, please could you tell how to purge the car AC system with dry nitrogen after solvent flushing? Is it very complicated procedure? Probably it is, since nothing on YT on this subject (including this rather detailed film, purging w/N_2 was not done though.
