A Guide to Buying Commercial AC Units

Different commercial sites have different air conditioning needs. There are small-sized office spaces to multi-storey buildings with different layouts, structures, and sizes. This wide variance requires you to have all the vital information to get a suitable commercial ac unit for your site. You cannot optimise its use without efficient planning and choice of the right system. And the absence of a properly functioning AC unit may cause interruptions in business, and you may even face the risk of losing customers. Here is a guide that could help you begin your search.

Type of system

The type of AC unit you need for your business is probably the first thing you must consider. The four types of systems are:

Single split system: Single split systems are the best choices for small spaces like cafes, server rooms, clothing stores, or small offices. These systems comprise an outdoor and indoor unit. You can easily install them without needing any ductwork, making them an affordable choice for many. Some of the benefits of single split systems are that they are compact, offer effective heating and cooling, and are available in different sizes and styles.

Ducted multi-split system: Ducted systems can efficiently heat and cool larger commercial spaces with multiple rooms as it works through a ventilation system. The complexity of installation makes ducted systems more expensive than single split systems. A ducted system can save space in your office building and increase the aesthetic appeal.

Rooftop packaged system: Rooftop packaged air conditioning systems are mounted on the roof of a building and are best suited for spaces lacking wall or floor space. These large systems are designed specifically for heating and cooling multiple rooms.

Variable refrigerant flow (VRF): VRF systems can adjust according to the operating conditions. The versatility of this system to maintain individual zone control on each floor and room makes it an energy-efficient choice for heating or commercial cooling spaces.


Determining the size of your commercial ac unit can be quite tricky. It depends on insulation, location, square footage, and other factors.

Commercial ACs are usually larger and more powerful as they heat or cool large areas. The cooling capacity of in-house air conditioners ranges between 2 and 25kW. The capacity for large and more complex commercial sites may vary between 10 and 100 kW or even higher.


Large commercial spaces are more complex due to segmented departments and office spaces with different heating or cooling needs. Due to such complexity, installing air conditioning systems requires more planning before purchasing. Also, keep in mind that commercial ACs are intricate, and maintaining them requires expert technicians familiar with such systems.


Commercial air conditioners are usually placed on the roof of the building due to the size and generation of noise. The placement also facilitates easy access to service while keeping it out of the way of the general public. You can also customise your commercial ac unit according to your space and install most of the AC components outside the building. This way, you can do your repairs and maintenance with minimal interruptions.

Instead of relying on popular brands, it is better to research the features and quality of different air conditioning systems to get the best deal for your purchase. No matter what type of air conditioning you buy, make sure it is installed by professional and experienced contractors. Also, don’t forget to check with the contractor for regular servicing and maintenance post-installation.
