Schraeder valves should have caps on them to prevent leakage. (I work in the HVAC field) They tend to leak as they age. These cars (F10 5 series) as well tend to have slow leaks at the condensor coil seams. Faulty design. The new designed condensors do not leak. If it starts to hiss again, they have to replace the condensor. A vaccum test(leak test) won't show it leaking. They have to pressurize the system with dye tracer and then they will see condensor "sweating" (leaking) refrigerant at the seams of the coil.

Drove the car for the first time in a few months yesterday. It was 95 degrees out. The AC did not blow any cold air at all...all hot air. I did not hear any hissing noises or the condenser turning on. I haven't seen any leaking on the floor in the garage. The AC was working perfectly fine last summer and the car has been hardly driven since then.
Any thoughts? So you still I think it might be leaking are weeping? Any other blockages or issues that I should look for? Thanks. |

Many people say that solar panels are something new today. Probably I agree with you because the weather sometimes is so hot. I didn't see people who have solar panels, but it seems to be something interesting. I believe that there are people who have electricity thanks to solar panels. It's like a mining farm, and the prices for solar panels will increase a lot. I'd like to see an aircon which is based on a solar panel. Guys, who know about this thinks, is it possible to do something from air conditioner servicing singapore?

It is a good practice to run the AC regularly even during the winter if possible.

For F06 R134a: Table 1 indicates the permitted loss of refrigerant after a specific period of time. There is no leak. refrigerant oil may not be topped up. Number of years since last filling, Permissible loss [g] 0 - 1 ≤ 30 1 - 2 ≤ 60 2 - 3 ≤ 90 3 - 4 ≤ 120 4 - 5 ≤ 150 Total system capacity is 850g so even a properly functioning system will need to be topped off over the years.

Also regarding the refrigerants, R-12 damages ozone while R134a does not (it has zero ozone depletion potential). It is only a greenhouse gas. Quote:
Agreed. |

so I did a vacuum test on the hvac system. it held vacuum over the course of about 2 hours, so I thought it was fine, however I know that over the course of a week id lose my cool air. so I thought to myself it can only really be 2 things in my mind, the evaporator in the car is bad, or the condenser is bad, not wanting to replace the evaporator behind the dash and thinking its well protected, and the lines are relatively short runs and what not, I figured my condenser would be bad, after 80k miles of rocks hitting it.
the last time I lost all my refrigerant I injected uv dye. once I removed the condenser I cleaned it off because there was a ton of crap in the fins. I checked the condenser with a uv light and saw a very small crack 4 inches above the bottom of the condenser were the dye leaked out. I am very glad I changed the condenser and now have good AC. on a side note for anyone doing this job, you do not have to undo the transmission cooler, or the power steering cooler, just lift and bend them out of the way and bend them back in, be patient and it will be fine. there are a few annoying brackets that are plastic in there, I swear I fought one for an hour, but it went back in, its a spacer for all the radiators. all in all its a moderate level DIY to replace the condenser.

once you remove the valve, you will have to draw a vacuum before refilling the R134. You might get away without drawing a vacuum if the system has residual pressure when you remove the valve and quickly put in the new one. The amount of air that gets in in the mean time will be minimal and you might get away with refilling the R134 to 2 bar on the low pressure side (with AC running. For a "perfect" job, you will need a machine.

Mine was resolved not only by a drain and recharge of R134a gas, but also a replacement of the aircon suction pipe, T-joint connector and refilling of aircon compressor oil. Parts plus labor was USD130.

I had the same issue with the hissing coming out of the vents. My condenser was damaged. Bmw charges me low $2k to replace it and install. Prior to this they checked for leaks. Recharged. The recharge would actually work for a short period time.
