1 Answer
The amount of **refrigerant gas** filled in a **1.5-ton air conditioner (AC)** depends on several factors such as the **type of refrigerant used**, the **manufacturer**, the **model**, and whether the AC is a **split** or **window unit**. However, typical values can be estimated.

### **Typical Refrigerant Quantity for 1.5-Ton AC**
| AC Type | Refrigerant Type | Approx. Charge Amount |
| ----------- | ---------------- | --------------------- |
| Split AC | R-22 | 1.2 – 1.4 kg |
| Split AC | R-410A | 1.0 – 1.3 kg |
| Window AC | R-22 or R-410A | 0.85 – 1.1 kg |
| Inverter AC | R-32 | 0.8 – 1.2 kg |
> Note: The tonnage (1.5 ton = 18,000 BTU/hr) gives an idea of cooling capacity, but the exact gas quantity depends on the **coil size**, **pipe length**, and **system pressure requirements**.
---
### **Things to Consider**
1. **Type of Refrigerant**: Common refrigerants are:
* **R-22** (older systems, now phased out in many countries)
* **R-410A** (widely used in modern systems)
* **R-32** (used in newer inverter ACs due to better efficiency and lower global warming potential)
2. **Pipe Length Impact**: If you install a split AC with a longer-than-standard copper pipe (e.g., more than 5 meters), the technician might need to add **extra gas** (typically about **20g per additional meter** for R-410A).
3. **Label and Manufacturer Data**: Always refer to the **technical label** on the outdoor unit, which specifies the **exact gas quantity required** for that model.
---
### How It's Measured During Servicing
* AC technicians use **pressure gauges** and **weighing scales** to ensure the right amount is charged.
* Overcharging or undercharging can reduce efficiency and **damage the compressor**.
---
### Summary
A 1.5-ton AC typically requires **about 1.0 to 1.4 kg** of refrigerant gas depending on the type used and installation conditions. Always refer to the manufacturer’s specification and use **certified technicians** for gas charging to avoid system damage.
