At A&S Ltd, we provide tailored commercial air conditioning installation solutions for offices, retail, industrial, healthcare, and education environments. As a trusted M&E subcontractor, we specialise in designing, installing, and maintaining efficient systems that ensure year-round comfort, energy efficiency, and regulatory compliance.
Whether you need a single split system for a comms room, a multi-split solution for multiple offices, or advanced VRF and HVRF systems for large commercial spaces, our experienced engineers deliver projects on time and to the highest standards.
Split Systems
Ideal when: You need cost-effective cooling for a single room or IT/comms suite.
Best for: Small offices, server rooms, reception areas.
Key benefits: Simple installation, reliable protection for equipment, flexible unit styles.
Split air conditioning systems are a cost-effective and straightforward solution for single-room cooling, making them a popular choice for IT suites, comms rooms, server rooms, and small offices. They consist of one indoor unit connected to one outdoor unit, providing efficient climate control without the need for ductwork.
These systems are ideal when only one area of a building requires cooling, offering precision temperature control and improved comfort for both people and equipment. In particular, split systems are widely used to protect sensitive IT infrastructure, preventing overheating that can cause costly downtime.
At A&S, we install a full range of split system units, including wall-mounted, floor-standing, and ceiling cassette models, ensuring the solution integrates seamlessly into your commercial environment. With fast installation times, lower upfront costs, and minimal disruption, split systems are a practical choice for smaller spaces or targeted cooling requirements.
For businesses looking to balance performance with affordability, split systems offer an entry point into commercial air conditioning that can be easily expanded later with multi-split or VRF technology.
Multi-Split Systems
Ideal when: You need comfort across multiple rooms with limited outdoor space.
Best for: Offices, shops, hospitality venues, medical practices.
Key benefits: Zonal temperature control, one outdoor unit for multiple rooms, and energy efficiency.
Multi-split systems are designed to deliver flexible comfort across several rooms or zones while using only one outdoor unit. Capable of supporting up to five indoor units, they are an excellent choice for commercial environments.
This type of system allows for independent temperature control in each room, meaning that different areas of a building can be cooled or heated according to usage and occupancy. For example, a meeting room can be kept cooler than a reception area, improving comfort while reducing wasted energy.
A&S specialises in designing and installing multi-split systems that integrate a mix of indoor unit styles (such as wall, ceiling, and floor-mounted models) to suit the unique layout and design of your premises. These systems are particularly valuable for buildings with limited outdoor space, as they require fewer external units than individual split systems.
The result is a cleaner, more efficient installation that reduces both running costs and maintenance demands, making multi-split systems a versatile option for businesses looking to upgrade their commercial air conditioning installation without investing in a larger-scale VRF system.
Sectors we serve:

VRF Air Conditioning
Ideal when: You need precise, energy-efficient control in larger or multi-zone buildings.
Best for: Offices, hotels, hospitals, schools, multi-storey sites.
Key benefits: Simultaneous heating/cooling, scalable design, excellent energy savings.
Variable Refrigerant Flow (VRF) systems are at the cutting edge of commercial air conditioning technology, offering precise climate control across multiple zones in medium to large buildings. A VRF system uses advanced inverter-driven compressors that adjust refrigerant flow to match the exact cooling or heating demands of each area. This allows for simultaneous heating and cooling in different zones; perfect for buildings with varied occupancy levels throughout the day.
VRF air conditioning is renowned for its energy efficiency, making it a smart investment for organisations looking to reduce operational costs and meet sustainability targets. With accurate temperature control, the system ensures optimum comfort.
Another key benefit is scalability: VRF systems can be designed to support small office fit-outs through to large multi-storey buildings. At A&S, we consult closely with contractors and building managers to specify the right VRF configuration, ensuring seamless integration into your mechanical and electrical infrastructure.
By choosing VRF, businesses benefit from reduced energy consumption, quieter operation, and longer system lifespan, delivering excellent long-term value.
Hybrid VRF (HVRF)
Ideal when: Sustainability and compliance are key project drivers.
Best for: Large offices, hospitals, hotels, universities.
Key benefits: Lower refrigerant use, safer water-based delivery, reduced carbon footprint.
Hybrid VRF (HVRF) technology represents the next step in sustainable commercial air conditioning. By combining refrigerant and water-based systems, HVRF delivers all the performance of traditional VRF while significantly reducing the amount of refrigerant required within occupied spaces. This not only lowers environmental impact but also reduces the need for expensive leak detection systems and associated maintenance.
HVRF systems are designed to provide simultaneous heating and cooling, making them ideal for large commercial buildings with diverse occupancy patterns. The water-based distribution within indoor environments enhances safety and compliance, particularly in sensitive applications where refrigerant use must be carefully controlled.
We design and install HVRF systems that balance sustainability with performance, helping businesses meet both operational and environmental goals. With their ability to offer zonal control, energy savings, and reduced carbon footprint, HVRF systems are increasingly chosen for projects where efficiency and compliance are top priorities.
For organisations seeking a future-proof solution, HVRF represents the best of both worlds; combining the flexibility of VRF with the environmental responsibility of water-based delivery.
Ventilation System: A new ventilation system was designed, with extract grilles installed within the toilet areas and a supply grille in the lobby area to maintain aesthetic and functional integrity. Read more.
