Less hot now

Last year our air conditioner stopped blowing cold air and we had it checked out. Ended up being low on coolant so we had it refilled. The guy cautioned that if it happens again that it could be a leak. Now this year it seems to be doing the same thing again. So we had it checked, which was not cheap, and sure enough our air conditioner has a leak. The guy filled it up with coolant but we're going to have to fix it. Unfortunately the leak is somewhere in the coils, and the fix is a lot more than the test.
