How do I know how much refrigerant I need?
The only way to really know how much refrigerant is in your system (and therefore how much we should put in) is by checking the system’s pressure with a pressure gauge. To check your system’s pressure you will need to know location of your low side port on your A/C.

Does Freon dissipate over time?
Freon (which is really just a particular brand of refrigerant) lasts forever. It’s not like gas in car; it does not get “used up.” You see, your air conditioner’s refrigerant system is a “closed/sealed system,” meaning that it does not allow refrigerant to escape in any way.
How do you calculate refrigerant tons?
Some commercial and industrial refrigeration systems are rated in Tons of Refrigeration (TR, tons). A ton is the amount of heat removed by an air conditioning system that would melt 1 ton (2000 lbs.)Converting between Btu/h and Tons of Refrigeration. Btu/h Refrigeration Ton kW 48000 4 14.1 54000 4 1/2 15.8 60000 5 17.6.
How much Freon is in a can?
One can of R-134a typically holds 12 oz. of refrigerant.
Is R-22 Freon still available?
The U.S. government has placed restrictions on R22 and has issued the requirement that R22 refrigerant must be eliminated from use in cooling systems by the year 2020. R22 is being replaced by R-410A, a safer material which is the current, compliant standard refrigerant in air conditioning equipment.
Why is R22 so expensive?
Why is Freon R-22 so expensive? The reality is you are a victim of supply and demand due to the shortage of Freon R-22. You see, nearly 30 years ago the EPA (Environmental Protection Agency) ruled that Freon R-22 should be phased out as it contains ingredients that have been shown to deplete the ozone.
What happens to old R22 refrigerant?
According to the Federal government, the refrigerant can no longer be used. The government seeks to eliminate its use by the ear 2020. Manufacturers will no longer use R22 at this point. The replacement may come with several consequences for homeowners with older air conditioning systems in Massachusetts.
What side do you charge AC on?
Every auto air conditioning system has two service ports: one on the high pressure and one on the low pressure side. When recharging with AC Avalanche refrigerant, for safety, you will charge through the low side service port. Never charge through the high side port.
