When repairing and refilling an air conditioning system, getting the exact amount of coolant in the system right is essential if you want it to work properly.  This is where A/C charging scales come into their own.  These handy tools work in conjunction with your AC coolant recycling equipment to refill the AC system properly and get it completely correct.

The more accuracy that you can work with when adding the coolant to an AC system, the better it will work, and the less likely it is for anything to go seriously wrong with it in the near future.  A/C charging scales are designed to provide a pre determined amount of coolant such as Freon into the system in order to get the system filled up as efficiently as possible.

An A/C charging scale is a tool that is designed to help you to get the right amount of coolant prepared for loading the AC.  In general, an air conditioning system will be rated to contain a specific amount of refrigerant in order to work correctly.  This is done by weight rather than volume, as this can vary greatly dependent on temperature.

When the refrigerant has been purified correctly, it can be weighed using an A/C charging scale to gauge the correct amount.  Then it can be injected back into the air conditioning at the correct pressure to make it work correctly.

There are a number of important EPA guidelines to consider whenever you deal with CFC coolants such as Freon.  These chemicals are very volatile, and have been linked with doing serious damage to the ozone layer.  This important part of the atmosphere is the main protection for the planet from ultra violet radiation from the sun.  The ozone layer protects our lives, and since the 1980s, when concerns about the effect of CFCs on the ozone layer first became important, governments aro
