How long to recharge freon in a ten-year-old Toyota?

Assuming this is the cause of an "inadequate cooling"
complaint?
The blower works.

TIA

Takes 10 minutes to gas it up. To find the leak repair it and charge it properly well.....

The two estimates she got several years apart were '5 minutes' and '1 hour' so I'm leaning toward telling her "about 10 minutes" to refill & check & repair leaks.

Thanks.

Could take 10 hours to find the leak, could take 10 hours to repair the leak, and it takes 10min to ~1hour to charge it up.

EDIT: didn't realize this is a car. Just gas it up.

At $20 a year for 134 I'd gas and let her go also

I think 'll tell her:
"Less than 1 hr to recharge and wait to see if it leaks. For very slow leaks just keep recharging once in a while."
Thanks.

Follow up:
"I had the coolant put in this morning. It took a little less than an hour. The system was checked for leaks. Total cost: $[xxx].-
Yesterday I contacted my mechanic (whom I trust). He told me the same thing. So now I am enjoying the COOL RIDE!"
so I guess she is a happy camper.

Thanks, all, for your help. :)
