I need an honest mechanic like you in my life! I paid over $500 for a RE tune-up. Only to find out that they never touched a thing. My check engine light, vcs and traction off lights are forever on. And AC (ha!) they “fixed” all right. That was another cost that I’m embarrassed to speak on. (Dealership did that one.)

Anyway, again, I am learning and watching videos to make sure that people are doing the right things. Thank you, Sir!

Great video man. Thank you for this. My 2010 Nissan rogue progressively blew less and less cold air. I went to refill the freon and the pressure was already maxed out. The compressor is also shaking a bit and it's constantly running 🤔... I guess I gotta take it in so I can be charged for this and 17 other things I "need." 😐

[jamiemorales]

Great! All I need is a $3000 machine...🤪😏

Amazing video, thanks for sharing!

My car is charged with Freon, the compressor turns on, but the AC is not cold at all, the metal hose under the hood going to towards the inside of the car is super cold though, I do not get what's going on.

Nice sharing my friend watching from Malaysia

Another great video RB!
What's the approx cost for this service?

AC isn't blowing cold on my 2002 Honda Accord V6 282K Automatic

To check for a leak, I pulled vacuum with a pump and using a manifold gauge. Disconnected and let system sit for about 8hrs. Reconnected gauge and system still had same vacuum readings. To check for blockage, I pulled vacuum from low side, and lost vacuum when I opened high side. Did the same for high side. To check low pressure switch, clutch didn't engage when system was empty. I pulled vacuum to ensure there was no air in system, then I charged with 1 can of only R-134a 12oz. The compressor clutch engages and condenser fan runs when ac is switched on. When I disconnect the low pressure sensor switch, the clutch and fan stop. The manual says capacity 15.9oz to 17.6oz OR 21.2 to 22.9oz depending on my condenser, so my 1 can is low but it is enough to exceed low pressure switch and engage clutch. Doesn't even blow cool air with 1 can and clutch engaging. Blend door works. Ambient temp is about 90F, engine warm, manifold pressure gauge shows around 100psi on both low and high when off. When on, clutch engages but no pressure change. Low doesn't drop and high doesn't rise. I'm leaning towards a bad compressor. I could add a 2nd can to bring up to spec but I don't want to waste it if that's not the issue and a part needs to be replaced. Especially since the clutch engages already, I feel like there should be at least slight cooling. I would prefer not to replace the compressor and find out it's the evaporator core and expansion valve. Your thoughts? Thanks in advance.

What is the name of your shop? Maybe I live near your area and I could swing by with the same problem thank you.

[christianbaza]

hey i have a 2014 camaro and did this service the beginning of summer i had a problem were the hot air would work and when i tryed cold air it would only blow neutral or sometimes a bit hot when i did the service my ac was back blowing really cold air but now a few days ago it started doing the same thing, also checked blend air door and its good, do you have any idea what it could be? thanks!

[johnny]

I bought a can of Freon and tried filling it. But gauge said it was filled enough already. AC line is not cold at all. So, these “do it yourself cans”, are useless without vacuuming the system first? Otherwise I’m putting Freon on top of hot air?

[johnkapel]

I never heard of charging an ac system with the vehicle off. Isn't it supposed to be running when you charge the system?

[gamingwithbre]

My a/c compressor on my 02 f150 keeps shutting on and off it’s brand new and has Freon but not blowing cold air out the vents

[sebastianbreier]

2014 Camero, AC compressor kicks on, has pressure in the system. But the air is semi cold. Not as cold as it should.

[Cryptosporidium-zusc]

Trying to charge the system on a 2007 Suzuki forenza, it was leaking from high side line at compressor so changed it and verified its sealed now, put a vacuum on it, charged with a can and the compressor comes on and stays on does not disengage at all and absolutely no cold air. I'm guessing it needs charged properly

[MsLaunt]

Hello! Just recently got Freon put in my car on Thursday; it worked Friday as well, come Saturday morning? no cold air anymore...

[DanteKurosaki]

My 2010 Honda Accord A/C slowly stopped blowing cold air, went to add Freon and it already had pressure. So, my question is, what would be the cheapest and best step to take next? Also, my air compressor doesn't seem to turn on to help circulate the air, it makes no sounds at all, maybe my compressor is out?

[raipier]

2007 Acura TSX.
A/C has been getting less cold over the last 2 years and really struggled last summer. Now it doesn't blow any cold air. Clutch engages and fans turn on properly. AC lines stay warm.

I used the gauge from an AC can and it shows ALERT and 60 psi on low pressure side. I have NOT added any freon from can or ever had it serviced, so it cannot be overcharged. When engaged it doesn't seem to put a noticeable load on car anymore.

Bad compressor? Low freon with air in line due to leak? Something else?

[JorgeGonzalez-ex]

2010 dodge caliber . Gauge shows its fully charged compressor is spinning but the lines are not getting cold. Do i nees to vaccum it?

[joseildefonzo]

I have a 2009 Nissan Murano and recently changed the ac compressor I recently added about 6oz of Freon then it started making a noise whenever I turned on the ac and the air wasn’t cold to assumed there was too much pressure so I released some and it was working fine for about a week now I have the same issue ac making noise and not blowing cold air

[jubyloo]

So dont you have to worry what caused the issue in first place? Like a leak? Because problem will return
