Repaired implies fixed!!!
As that seems not to be the case, my guess is the right word would be charged.
Story:
We were helping Saundra's uncle in his last days. Summer started with it's typical heat. Well the service needed to be called to "fix" the ac. All that was needed was a charge. This had gone on for years. Well having a father in the business I had opportunity to learn from him.
Watching the tech I noticed he didn't put a cap on the port. When I asked about the cap he told me it wasn't necessary. I told him to indulge me and put one on.
You see freon is the big profit in the business, so I broke the profit cycle. Guess you might be "fixing" the cycle soon!!!
Of course the system may have a legitimate leak in that case get another ac man.
