Best Commercial Air Conditioning Systems for UK Business Use
Choosing the best air conditioning system for your business can be challenging. With many systems available, selecting the right one can feel overwhelming, if not impossible. Yet, whether you run an office, a restaurant, a school, or a care home, a quality AC system doesn’t just keep you comfortable. It ensures everything runs smoothly for you and your business.
At Asbury, we understand the importance of choosing the right air conditioning solution. With over 60 years of experience in Dorset, Hampshire, and Wiltshire, we’ve gained valuable insights into what works and what doesn’t.
In this guide, we’ll walk you through the different systems available. So, you can make a more informed choice that balances comfort, energy efficiency, and long-term savings.
What to Think About Before You Choose
Before you compare the different air conditioning systems, consider a few essential points. These will help you choose the right system for now and for years to come.
Building Size & Layout
The layout and size of your building are key in deciding which system best suits your needs. In larger, open areas like showrooms or school halls, ducted systems are ideal. They cool the space evenly using discreet, hidden vents. Smaller spaces, like offices or medical rooms, can benefit from multi-split systems. These systems let you control the temperature in different areas separately.
Energy Efficiency & Costs
In our climate, energy-efficient systems are more important than ever. Many businesses are now opting for inverter technology or Variable Refrigerant Flow (VRF) systems as energy bills go up. These options lower energy consumption and support compliance with the UK’s Building Regulations Part L. This way, you can save money while staying within the rules.
Aesthetics & Space Requirements
For businesses with heavy customer foot traffic, such as restaurants or care homes, appearance is as important as function. Ceiling cassette systems work well in these areas. They offer effective cooling while keeping wall and floor space free. These systems are discreet, visually appealing, and perfect for open-plan spaces.
Noise Levels & Comfort
If you manage a busy office, school, or care facility, quiet operation is essential. VRF and split systems focus on low noise levels, so your staff or residents won’t be disturbed by loud units.
Ongoing Maintenance
An air conditioning system is a valuable investment. To maximise its lifespan, you need to maintain it well. Proper care also boosts its energy efficiency. At Asbury, we provide maintenance contracts that help stop problems before they start. Maintenance helps cut down on expensive breakdowns and keeps your system running well year after year.
What Are the Main Types of Commercial AC Systems?
Now that you know the key factors, let’s look at the best commercial air conditioning systems for your business. Different businesses have different needs, and the right system for you will depend on your space, budget, and efficiency goals.
Split & Multi-Split Systems
Split systems are one of the most common air conditioning solutions for smaller businesses. They are straightforward, easy to install, and effective at cooling individual rooms. With one indoor unit connected to an outdoor condenser, they are ideal for offices, small retail shops, and care homes. These systems are particularly appropriate wherever zoning and minimal installation disruption are priorities.
Multi-split systems function similarly, but they allow you to connect multiple indoor units to one outdoor unit. This system suits medium-sized businesses, such as restaurants, schools, and offices with a few rooms. It allows for independent temperature control in different areas. Their flexible design is appealing when you need both cost savings and good performance.
VRF (Variable Refrigerant Flow) Systems
VRF systems are a wise choice for larger commercial properties, including hotels, multi-storey office buildings, and mixed-use developments. These systems heat and cool different areas of a building at the same time. To achieve this, they use a refrigerant that moves to various indoor units.
VRF systems are energy-efficient because they recover heat. They take heat from one space and transfer it to another. For businesses that have changing heating and cooling needs, VRF systems are a flexible and lasting solution. They work well in different rooms at different times of the day. Plus, they are discreet and quiet, making them ideal for environments where comfort is paramount.
Ducted Systems
Ducted air conditioning systems present a smart, integrated way to cool spacious, open areas. Hidden in the ceiling, ducted systems distribute cool air through ducts placed throughout the space. They are a great choice for businesses that need cooling without being obvious. Examples of this include large offices, retail shops, and restaurants.
Ducted systems have a key advantage: they can cool larger spaces without the visual clutter of wall-mounted units. They can also connect to building management systems and help manage temperature zones, which helps save energy and improve efficiency.
Ceiling Cassette Units
If you run a space with limited floor and wall space, like a boardroom, reception area, or showroom, ceiling cassette units could be the perfect fit. These units install directly in the ceiling and blow air in four directions, providing even cooling throughout the space.
Ceiling cassette systems work well in rooms with high ceilings or mixed-use spaces. They offer a cool and quiet solution that keeps employees and customers comfortable. Plus, since they are in the ceiling, they don’t use any floor space. This makes them ideal for businesses that want both performance and style.
