It is not 1 guage, it is a dual guage that measures high and low side pressures that are used in conjuction with the indoor and outdoor temp, unit size, and blower capacity to determine if you have the correct amount of refrigerant in your system.
not dure if this will help but when i charge a unit either low or complete charge,the jug is weighed before the charge and after to see the weight of freon
Yes, Freon is toxic at certain levels. Overexposure causes central nervous system depression and possibly cardiac arrhythmia. Depending on the type of freon, it is also extremely cold and can cause severe burns if handled improperly.
Freon under pressure, much like LP and butane are liquid. At sea level pressure, freon becomes a gas. For freon to work in a refrigeration system, it must be able to transform from liquid to gas to liquid. So, to fill a system, it must be put into that system in liquid form. To do this, the bottle containing freon must be tipped, otherwise only freon the gas would be expelled.
Freon is harmful to the environment because of the chemicals that it is made from. These chemicals are bad for the environment and ozone layer.

how do you check freon on central ac and what should the guages read.
The 1988 Pontiac Bonneville originally used R12 freon, this freon is no longer available due to government regulation. Your A/C system must have it's A/C service ports replaced. Then the system filled with the correct amount of R134a freon.
I just had 2 pounds of Freon added to my central A/C and was charged $30 a pound.
overcharging a central air unit system with refrigerant(freon) will cause the head pressure to be?
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.
yes
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 have a '92 and it is Freon 12. There are a couple of ways to tell. 1. There is a sticker under the hood that will tell the type of freon and the amount. 2. The best way is to look at the freon input connection. Freon 12 is a 1/4" flare fitting and freon 134A is much larger. A freon 12 system can be converted to 134a with a kit that is very available. They make these kits because freon 12 is unavailable and is now illegal to sell.
Freon is a dangerous and deadly gas that can be fatal. However, the amount of Freon in a refrigerator is usually minimal, but it is still dangerous.
Automotive Freon is R-12 (or the new R-132 and R-134). Central air freon is R-22. They are not compatible because of their different boiling points. R-22 is being phased out through the year 2010, but there is no standard replacement.
low on freon
