The AC model
Refrigerant type
Installation conditions.
A 1 ton AC typically uses 0.68 to 0.91 kg (1.5 to 2 lbs) of refrigerant.
How Much Gas Filled in 1 Ton AC?
Depending on the design and type of gas, several contemporary models run effectively on 400 to 600 grams. There is no single fixed quantity for all 1 ton ACs. Different refrigerants require different charge levels:
R22 (older models): Higher quantity due to lower pressure
R410A: Usually around 800 to 1,100 grams
R32 (newer models): Around 400 to 600 grams
The gas type directly affects pressure, cooling efficiency, and charge weight. Every company has a unique design for their air conditioner. The amount of gas required by the system depends on coil size, compressor type, and inverter technology. For this reason, the gas consumption of two 1-ton air conditioners may differ. Correct gas filling matters because;
Undercharging raises electricity costs and decreases cooling.
The compressor and internal parts can get damaged by overcharging.
Inadequate gas levels degrade efficiency and shorten the life of ACs.
Always refer to the user manual or the manufacturer's label on the outdoor unit. It specifies the precise type and weight of refrigerant that is needed. For accuracy and safety, you can also consult a HVAC technician.
