They use R410a eco friendly refrigerant gas now.
The refrigerant (freon) in any air conditioner should last the life of the unit. If not, you have a leak.
To buy ac Freon you need to be certified and to add ac Freon to central air conditioning unit is risky.The air conditioner filters are normally located in return duct grills or in the air handler. Read how to change air conditioner filters.
overcharging a central air unit system with refrigerant(freon) will cause the head pressure to be?
That sounds reasonable to me. I have in my home, a very large (22,000 BTU) through-the-wall air conditioner, designed to cool three large rooms. It uses 3.5 lbs of freon. A whole-house unit I can easily see using as much as 9 lbs.
actually this is a pet project of mine to produce a Freon-less A/C unit
$100
The recommended type of freon for a window AC unit is R-410A.
depends on freon type,quanity,hourly rate of hvac co.
As much as went in. Not trying to be a smarta**, but there is no info on unit size or lineset length which are the 2 most determining factors of unit charge amount.

Unless you are epa certified you shouldn't add any r22 to your air conditioner. And if you are, you should probably already know... It depends on what type of unit it is. Is it a central split unit or a window unit?
To put freon in an air conditioner, you need to locate the service valve on the unit, connect a charging hose to the valve, and slowly add the freon into the system while monitoring the pressure levels. It is important to follow safety guidelines and regulations when handling freon.
