Well it would cost no more than $10 to buy one of those cans of R-134a with the built-in gauge. I recommend buying one, using the gauge to check your pressure. If you don't need to add any refrigerant, then you can return the can to the store, get your money back, and then take it to get checked out. That way you can rule that out first.
