Types of Air Conditioning Systems for Commercial Spaces How Long does a commercial air conditioning system take to install? End of Lease Cleaning After Installation According to the International Labour Organisation (ILO), productivity drops above 26°C in commercial spaces. Along with proper cooling, office cleaning improves air quality by reducing dust and allergens.
For leased properties, end-of-lease cleaning ensures the space is spotless and meets lease obligations. Once the mercury reaches 34°C, it goes down by as much as 50%, which is why it is important to have a good air conditioning system installed.
Without one, you might not be complying with state legislation for specific aspects such as food storage, healthcare, or the protection of your equipment, and you certainly won’t be offering your customers as pleasant an environment to shop as you could.
However, if you have just bought a new system, you might not be aware of what is involved in the installation process, which is very different from what happens in private homes. That’s why we have put together this guide, which outlines what you should expect.
Before you can have an air conditioning system installed, you must purchase one, and when it comes to commercial spaces, there are several types available. Which one you pick will be influenced by factors like how big your floorplan is, what level of energy efficiency you are looking for, and your overall budget.
But here are some of the best options you can choose from. These types of systems are best for small offices or retail spaces and comprise an indoor unit that is connected to an outdoor compressor. Proper air compressor installation is crucial for the optimal performance of split systems in commercial environments.
Overall, they are cost-effective, relatively easy to install, and offer a localised cooling solution. 2. Ducted Air Conditioning
If you have a large space for which you require even cooling, then ducted systems are a good choice. They use concealed ducts to distribute cool air throughout the building, which can’t be seen as it is incorporated into the ceiling.
Multi-split systems are popular in medium-sized spaces because they enable several indoor units to connect to a single outdoor compressor. In doing this, they can cool different rooms at varying temperatures, which helps you to save on energy costs in rooms that are not being used. 4.
Variable Refrigerant Flow (VRF) Systems VRF systems are ideal for large office spaces or multi-story buildings such as hotels because they are very efficient and can simultaneously heat and cool different zones as required.
In areas with low humidity, such as warehouses or industrial spaces, evaporative coolers are a good, energy-efficient option because they use water to cool air. The process of putting in an air conditioning system into a commercial space is perhaps best explained in this installation guide by Alliance Climate Control .
However, it generally goes something like this: 1. Initial Consultation and Site Inspection You will need to engage the services of a professional, experienced, and licensed HVAC contractor who will book you in for an initial consultation to assess your needs.
They may also do a site inspection to evaluate the space you want to be cooled and go through what they think are the best options for you. Typically, after you send an enquiry, most contractors will aim to respond within 24 hours to arrange this visit.
The site inspection gives them a chance to analyse your premises, discuss your requirements in detail, and consider your timeline and budget. During this visit, the contractor will also provide tailored recommendations and a clear, final quote—so you’ll know exactly what to expect, without any hidden fees or surprises after the installation is complete.
Once you’ve chosen your preferred system, the contractor will create a custom-designed plan that will identify where the units, ducts (if applicable), and controls will be placed within your commercial space. This will be designed to ensure it is cooled as effectively and quickly as possible when it is turned on. 3. Pre-Installation Preparations

Practical next steps for Air Conditioner Installation Guide
- Share the property type, size, condition and access information before requesting a quote.
- Identify priority rooms, surfaces, stains, pets, furniture and any inspection or handover date.
- Separate cleaning from repairs, pest treatment, plumbing, electrical or restoration work.
- Confirm inclusions, exclusions and optional services before the appointment.
