## How much Freon does a 3-ton AC hold?

about 12 pounds

The amount of cooling for your system can be estimated in the range of 2 to 4 pounds per ton. The 3-ton AC or Heat Pump with a 35 foot lineset will need a total of about 12 pounds of refrigerant.

**How much refrigerant does a 3.5 ton AC hold?**

The rule of thumb is two to four pounds of refrigerant per ton of your air conditioning unit.

### How much R-22 does a unit hold?

5 to 15 pounds

Typical residential air conditioning units hold from 5 to 15 pounds of R-22. Even more, according to the EPA, production and sale of R-22 be cease completely by 2020.

**How much R-22 do I need?**

A typical line set size for a 2 Ton air conditioner is ¾” and we can see that in R22 Freon systems we will need to add 0.62 ounces of Freon for each foot of line set over 15 feet. A fifty foot line set will cause you 2 Ton air conditioner to use an additional 1 pound 5.7 ounces.

## How do you calculate refrigerant capacity?

Divide the quantity of refrigerant that the heat pump moves by the time it takes to move it. If it pumps 3.6 kilograms of refrigerant in 10 seconds: 3.6 / 10 = 0.36 kilograms per second.

**How do I calculate how much Freon I need?**

No complicated math required, you simply add together the gas in the pipe, the compressor/condenser section, and the evaporator = total charge. As a result, they only capture between 30-40% of the system charge and therefore under report capacity charge.

### How many pounds of Freon does a 2.5 ton AC unit hold?

Now you have a guesstimate of total Freon in a 2.5 ton unit. These weights are base on an average of three pounds of refrigerant per ton of cooling capacity. They are approximate and should not be used to determine an exact or most effective level of refrigerant to operate any heat pump efficiently.

**How many pounds of Freon does a 4 ton AC unit hold?**

The rule of thumb is 2 to 4 pounds of refrigerant per ton of air conditioning unit.

## 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. At this point, R22 will no longer be manufactured and cannot be used as a refrigerant in new air conditioning systems.

**Why is R22 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. Because it’s so dangerous, countries around the world have been slowly phasing out this refrigerant since 2010.
