Your air conditioning is no longer cooling.
There can be a lot of reasons your air conditioning is not cooling. I had a lot of customers in past who claimed AC not cooling. So they assumed the system might be out of Freon gas. Of course this is not right and it is a merely a miss conception. An air conditioning repair process involves to check all components. These include electrical, mechanical and all others step by step to pin point the exact problem. Some times a repair can be a simple as re-setting main circuit breaker in main panel. if this did not solve the problem then you need to call an air conditioning repair company repair specialist to do the work.
