When it comes to maintaining a comfortable environment in your workplace, having the right commercial air conditioning system is crucial. Whether you’re running a small office, a large retail space, or a multi-floor building, selecting the correct commercial air conditioning unit can make a significant difference in energy efficiency, comfort, and long-term costs.
This guide will help you navigate the various options available for commercial air conditioning, understand the different installation methods, and determine what might work best for your specific needs.
Types of commercial air conditioning units
Commercial air conditioning units come in various forms, each suited to different types of spaces and needs. Understanding the different options is key to choosing the right system for your business.
1. Split system air conditioners
A split system is one of the most common types of commercial air conditioning units in the UK. These systems consist of two components: an indoor unit and an outdoor condenser. The indoor unit cools the air, while the outdoor condenser dissipates the heat.
- Installation costs: installation for a basic split system typically ranges from £1,500 to £2,500, depending on the size of the unit and the complexity of the installation. If extra work like rewiring or upgrading electrical systems is required, costs may rise.
- Maintenance costs: regular servicing is essential to keep split systems running efficiently. Expect to pay around £100-£150 annually for basic maintenance.
- Running costs: split systems are generally energy-efficient, with average running costs for a small to medium office around £300-£600 annually, depending on usage.
2. Multi-split air conditioning systems
For businesses with multiple rooms or larger spaces, a multi-split system could be more suitable. This system allows you to connect several indoor units to a single outdoor unit.
- Installation costs: installing a multi-split system can be more expensive than a basic split system. Costs typically range from £2,000 to £5,000, depending on the number of indoor units required and the complexity of installation.
- Maintenance costs: maintenance for multi-split systems is more involved than a single split system due to the increased number of indoor units. Annual servicing usually costs between £150-£300.
- Running costs: multi-split systems allow you to control individual rooms, potentially lowering overall running costs. A small business might spend between £500 and £1,000 annually, depending on usage and system size.
3. VRF/VRV systems
Variable Refrigerant Flow (VRF) or Variable Refrigerant Volume (VRV) systems are designed for larger commercial buildings such as hotels, shopping centres, and hospitals. These systems are highly efficient and allow for individual climate control in multiple areas of a building.
- Installation costs: VRF systems are more complex to install, and the costs reflect that, typically ranging from £5,000 to £10,000 or more, depending on the size and scope of the project. Large buildings with complex requirements may see costs above this range.
- Maintenance costs: maintenance for VRF systems is also more expensive, with costs generally between £300 and £600 per year. Given the complexity, it’s advisable to have a comprehensive maintenance contract.
- Running costs: despite the higher upfront and maintenance costs, VRF systems are highly efficient, with annual running costs often ranging from £1,500 to £3,000, depending on the building’s size and usage.
4. Ducted air conditioning systems
Ducted air conditioning systems are an excellent option for larger spaces that require a more discreet and aesthetically pleasing solution. These systems consist of a centralised unit that distributes air through ducts concealed in the ceiling or walls.
- Installation costs: installing ducted systems is more labour-intensive, with cost varying greatly depending on the size of the building, complexity of the ductwork and people needed.
- Maintenance costs: maintenance involves both the unit and ductwork, making it more costly than simpler systems. Expect to pay an extra annual fee for servicing, with additional costs if duct cleaning is required.
- Running costs: ducted systems are effective for cooling large spaces but can have higher running costs, depending on usage and the energy efficiency of the system.
Key considerations for commercial air conditioning installation
When planning a commercial air conditioning installation, there are several factors to take into account to ensure the system is effective, efficient, and compliant with UK regulations.
1. Energy efficiency
Energy efficiency should be a top priority when selecting a commercial air conditioning unit. Modern systems come with various energy ratings, and choosing a high-efficiency system can significantly reduce your long-term running costs.
The Energy Performance of Buildings (England and Wales) Regulations require all non-domestic buildings to meet certain energy standards, so selecting a system with a high energy rating can also help you stay compliant.
2. Installation complexity
Some commercial air conditioning units are easier to install than others. Split systems, for example, are relatively straightforward, while VRF and ducted systems may require more complex installations that can take longer and cost more.
It’s essential to work with a professional contractor who specialises in commercial air conditioning installation to ensure the system is set up correctly and operates efficiently.
3. Ongoing maintenance
After your commercial air conditioning installation, regular maintenance is crucial to keeping the system in optimal condition. Scheduled servicing can prevent breakdowns, prolong the lifespan of your equipment, and ensure it continues to run efficiently.
Think about your needs and talk to an expert
Choosing the right commercial air conditioning unit can have a significant impact on your business’s comfort and energy costs. Whether you’re looking for a simple split system for a small office or a more advanced VRF system for a large building, it’s essential to consider factors like energy efficiency, installation complexity, and ongoing maintenance.
