Agree with Jayare, the most common problem will be low refrigeration.
If you don't have gauges available to you, if your system has 134, just pick up a can and install it yourself, read the directions, not hard to do.
And if it works for a day or so and then stops again, you have a leak you need to find..
Did this on my wifes E420, after I figured out it was leaking, tried it the second time with dye. Unfortunately the green dye came out of the HVAC box, the dreaded evap leak.
I bit the bullet and had the dash taken out to get to the evap, expensive, but done for the life of the car. I remember Jayare posting years back about a sealer that worked for him on his 400..
