O General 2.0 Ton (24,000 BTU) – ARGH24CMTA-U / AOGH24CBTA-U
Product Overview: The ARGH24CMTA-U is a 2 Ton (24,000 BTU/h) ducted split AC, well-suited for cooling larger bedrooms, living rooms, or offices (~30–35 m²). It offers a step-up in capacity while retaining the slim form factor (240 mm height indoor unit) and single-phase convenience of the smaller model. This unit provides a strong cooling punch for its size – rated 22,000 BTU/h at T1 conditions – and is popular for medium-sized spaces in villas and apartments. The outdoor unit (AOGH24CBTA-U) remains compact yet robust, featuring enhanced heat exchange to handle the higher load. Users will enjoy the same quiet operation and feature set across the range: inverter efficiency, adjustable airflow, and smart controls. With a slightly larger fan and coil, the 24k model ensures quick pull-down times (fast cooling from startup) and stable temperatures even with multiple rooms ducted.

Key Features:
- Powerful cooling with 6.45 kW capacity (T1) that can ramp down to ~2.0 kW at minimum load for energy savings.
- It has a wide operating range, maintaining ~19,400 BTU/h at T3 (46 °C ambient).
- The 2 Ton model still operates on 230V single-phase, making it suitable for most residential supplies.
- Noise levels are low – about 38 dB(A) on high fan (indoor) which is very quiet for a 2 Ton ducted unit.
- Installers will appreciate the identical chassis size to the 18k unit (it shares the 1,000×700 mm footprint) and only a modest increase in weight.
- This model is often chosen for master suites, small open-plan areas, or two connected rooms.
- Optional extras include the wired controller, Wi-Fi adapter, long-life filter, and fresh-air intake kit (to introduce ventilation air into the return duct if needed).

Usage Note: The 24,000 BTU unit can handle a medium-sized living room or a couple of bedrooms joined by ducts. It’s a popular choice for apartments due to the single-phase power and compact size. Ensure adequate electrical provisioning of ~9 A plus a safety margin on the circuit.
Duct design tip: use a good return air path and consider sound attenuators if running at high static in noise-sensitive areas (though the unit is quiet, air rush noise can occur at high flow). Regular maintenance (cleaning filters and checking the outdoor coil for dust) will keep the efficiency high.
