State-of-the-art AC Units built for efficiency, flexibility and control.
Our high-performance AC units combine inverter technology, zone-level control, and BMS integration — delivering intelligent cooling for modern buildings.
AC technology that pays off.
Optimize energy use with inverter-driven performance
Enhance indoor comfort with precise temperature regulation
Be energy efficient and cut costs
Smarter cooling for every building.
From apartment towers to executive offices and busy retail spaces, cooling needs can vary considerably — and our energy-efficient split air conditioning units are designed to meet those needs.
Equipped with modern inverter technology, they provide faster cooling, quieter operation and reduced energy consumption, all while lowering electricity bills. These systems maintain a consistent indoor climate year-round, providing performance, style and control in one sleek solution, whether it’s the height of summer or a cooler evening.
The tech behind the comfort.
Each split AC unit functions as a compact, self-contained system — ideal for targeted, zoned cooling. Indoor units are mounted discreetly on walls or ceilings and connected to outdoor condensers via slim refrigerant lines. Inverter compressors adapt dynamically to room conditions, ensuring powerful cooling at start-up and efficient operation as temperatures stabilize. The result: optimal comfort with minimal noise and energy use — all without the complexity of chilled water systems or central pumping.

Technical Features
- Inverter technology: This ensures adaptive performance with less energy waste, resulting in smoother cooling, fewer temperature fluctuations and quieter operation.
- Zoned control: Each unit operates independently, enabling precise temperature management by room or area — perfect for multi-use spaces and variable occupancy.
- Quick installation and low infrastructure impact: With no chilled water loops, pumps or large ducts required, split units are easier to install and are ideal for both new builds and retrofits.
- Smart Integration: Compatible with most building management systems (BMS) for remote control, automated scheduling and proactive diagnostics.
- Sleek, space-saving design: The indoor units can be installed in ceilings or walls to preserve architectural aesthetics and maximise usable space.
- High Seasonal Efficiency Ratio (SEER): Designed for regions with extreme temperature variations, it delivers optimal performance even in harsh summer conditions.
Frequently asked questions
Split ACs are decentralized systems that cool individual zones directly, without the need for chilled water, pumps, or extensive ducting. They're faster to install, more flexible, and often more energy-efficient for smaller or varied spaces.
Yes. All systems installed by ista comply with ESMA and QCC guidelines and use eco-friendly refrigerants. We ensure full alignment with all regional energy-efficiency laws.
Yes. The compact, modular nature of split units makes them ideal for retrofits — especially in buildings where space, infrastructure, or cooling zones are complex or limited.
We offer a full-service approach: On-site assessment, system design, compliant installation, secure mounting, and optional ongoing maintenance. Every step is tailored to your building’s needs.
Our units use inverter technology to adapt cooling output to real-time demand, reducing energy use during partial load conditions. This leads to lower electricity bills and fewer emissions, without compromising comfort.
