How Much Freon Should a 2 Ton Air Conditioner Take? The picture here is the nameplate to a split system air conditioning system. This label states that this 2 Ton outdoor air conditioner requires 3 pounds and 14 ounces of R22 refrigerant.
Most air conditioners range between 1 and 5 tons. Since an air conditioner uses an average of 2 to 4 pounds of refrigerant per ton, a 3-ton AC will need an average of 9 pounds.
Two to four pounds of refrigerant per ton of air conditioning unit is a good rule of thumb. The majority of residential air conditioners now weigh between one and five tons.
For every 1 degree F increase in temperature above 68 F (20 C), add 2 oz (60 g) of R22 refrigerant per ton of cooling capacity.
The size of an average residential air conditioning unit runs between one and four tons. Units above four tons are considered commercial units. Here's the kicker: you can expect to use one to four pounds of R-22 refrigerant per ton.

The general guideline used when calculating the amount of Freon in a residential A/C unit is 2-4 pounds per ton of cooling. For example, if you install a new A/C system rated for a five-ton load, the system will require 10-20 pounds of refrigerant.
In general for 1 Ton 1.2 to 1.3 kg is required. So for 2 Ton it will b around 2.5 Kg.
NEVER Exceed Refrigerant Recovery Tank Limits
By law, a tank can only be filled to 80% capacity and must be kept under 122°F. It is recommended to fill to 2 lbs less than the 80%. For example, a 30 lb cylinder can hold 22 lbs of refrigerant and a 50 lb cylinder can hold 38 lbs of refrigerant.
Each make and model of air conditioner needs a slightly different amount of AC refrigerant. According to PG&E, most central air conditioning systems use two to four pounds of refrigerant per ton of cooling capacity.
A ton of refrigeration is a rate of heat transfer, not an amount of heat. One ton is equal to the heat absorbed in melting 2,000 pounds (1 ton) of ice at 32°F in 24 hours (1 day). This equates to 12,000 Btu/hr or 12,000 Btuh.
R-22 Freon is not even available for purchase unless you're an EPA-licensed technician. So, you can't buy Freon from Home Depot for your HVAC needs. The good news is that you can still get it, though.
Why is R-22 refrigerant so expensive? R-22 refrigerant is so expensive because there's such a limited supply of it left. You see, R-22 is an “ozone-depleting substance” and is extremely harmful to the environment.
Refrigerant gases can be reused after cleaning and separation, and there is a robust nationwide industry providing refrigerant reclamation services for big users.
The can should be stamped with an empty weight. Also, you can fill only to 80%, so 40 pounds in a 50 pound tank. Take the empty weight and add 40 pounds, and that is all a recovery tank should weigh when full.
Tare weight (TW) is the weight of the empty tank. The total weight of the tank is everything inside the tank plus the tare weight. Scales only measure the total weight, so you must remember to include tare weight when determining your maximum recovery fill.
This is what he told me: For a 1.5-ton AC, 700 to 900 g of gas is required whereas around 400 to 600 g of gas is required for a 1-ton AC. However, you need to check which gas you're filling as R22 requires 60 to 65 PSI, R32 requires 110 to 120 PSI, and R410A requires 110 to 120 PSI.
The pressure values of R22, R407c, R410a and R417a are 1097 Kpa (159 psi), 1248 Kpa (181 psi), 1734 Kpa (252 psi), and 995 Kpa (144 psi), respectively, at a 300˚K (540˚R) bubble point. ...
If your unit is low on refrigerant, you will need 2-4 lbs. per ton of AC cooling to refill the refrigerant to optimum levels. Most houses have air conditioning units that range between a half-ton to 5 tons.
Under EPA regulations, only a certified professional can recharge your home's HVAC system.
In 2010, the U.S. stopped the sale of newly manufactured residential air conditioning units and heat pumps that use R-22 because of its particularly harmful impact on the ozone layer when released into the air. On January 1, 2020, the U.S. Environmental Protection Agency (EPA) banned the production and import of R-22.
