Rudd began to blow air - Is it time to add the Freon?
My house Rudd central air conditioner UAKA-024JA2 began to only blow but no cold air today. Yesterday it still blowed cold air. It was manufactured in February 2003 and has never been added Freon since it was installed.
Is it possible that it is the time to add the Freon or it is the leaking problem? If it is likely the Freon problem, is it easy to add it by oneself or had better to call the professional to add the Freon because of special tools and materials required? Thank you for your answer.
