Never! If it's low on refrigerant it has leaked.
The refrigerant (freon) in any air conditioner should last the life of the unit. If not, you have a leak.
I just had 2 pounds of Freon added to my central A/C and was charged $30 a pound.
how do you check freon on central ac and what should the guages read.
Actually no technical skills needed to check the Freon level. Home central air conditioners have a Freon scale on it. One just need to read the scale and determine whether the level of Freon is sufficient.
i would not do it.. Epa requires to you have a license to purchase and use certain type of hfc and cfc freon
The answer should seem obvious... you have a leak. It could be anywhere in the system, which is unfortunate for you. You'll probably need a tech to come and do a leak test on your system.
when the air does not comes out cold in your ac will be a good time

It would take 30 min. average time to add this charge to the system.

There are quite a few reasons why an air conditioner could be running but not cooling. One should first check the Freon lines and ensure that there is an adequate amount of Freon available.
