Commercial Air Conditioning: Ultimate Guide

Are you having difficulties keeping your business space cool during hot weather? Is your residential air conditioner having trouble cooling your office? Good news for you because, unlike residential air conditioning units, commercial air conditioning units are built to overcome the challenges of cooling large spaces. This blog will help you familiarize yourself with the concepts of commercial air conditioning together with the different systems, purposes, and factors to consider when the time comes to decide which to choose for your business.

Commercial Air Conditioning



What is Commercial Air Conditioning?

A commercial air conditioning unit is a cooling unit designed for heavy usage in large establishments. Not only does it cool the surrounding air, but it also maintains the ideal conditions needed by businesses such as accurate and precise temperatures and humidity levels for food storage.



Types of Commercial Air Conditioning:

There are different types of commercial air conditioning systems available in the market to accommodate the different needs of the industry. The following are some of the main types that may assist you in choosing the appropriate system for your business.


1. Central Air Conditioning

A central air conditioning system uses a network of ducts to distribute cold air over a wide area making it an efficient system for large buildings. A single control panel manages the entire cooling system which is a cost-effective approach for cooling an entire building.

2. Ductless Mini-Split Air Conditioner

 This type of system is ideal for buildings with small spaces because it is easier to install and provides control over individual zones. It is designed with one outdoor unit and at most 4 indoor units that can be adjusted and controlled independently. The lone outdoor unit is the one that cools the refrigerant and then pumps it to the individual indoor units to absorb the heat within its surroundings. Since the system is ductless, it is perfect for establishments without any existing ducts which makes it more energy–efficient and easier to maintain compared to central air conditioning systems.


3. Multi-Split Air Conditioner

 This system is like a mini-split, but it can connect up to 8 indoor units to a single outdoor unit which makes it ideal for medium-sized businesses. Like the mini split, each indoor unit can be accessed and controlled independently which allows customized cooling conditions for multiple rooms or zones and it also doesn’t require extensive ductwork to function efficiently.


4. VRF/VRV Systems (Variable Refrigerant Flow/Volume)

This type of system offers more advanced control and the ability to cool different areas or zones simultaneously. The system optimizes the energy consumed by adjusting the refrigerant flow to each indoor unit, only cooling the area where it is needed. This type of system is ideal for buildings that need more complex control over their temperate setting.


5. Chillers

Unlike the other systems, chillers use water to indirectly cool the air to provide cold air within a large building or establishment. Chillers are typically large cooling systems for large infrastructures where they act like big refrigerators that can provide cold air to various areas of a large building. It works by sending the chilled water to the cooling coils in air handling units which then spreads the cooled air with the help of blown air in different areas.




Applications of Commercial Air Conditioning

Commercial air conditioning is not only for keeping us cool during hot weather, but it is also an integral part of any business that relies on its cooling characteristic to meet specific conditions. The following are the different ways commercial air conditioning systems are being utilized:


1.     Offices and Retail Stores

Offices and retail stores use commercial air conditioning to create a comfortable atmosphere for both customers and employees which then raises productivity and promotes a relaxing atmosphere.


2.     Restaurants and Food Services

Accurate and precise temperature is needed in restaurants and food service industries to ensure food safety while preserving the quality and freshness of the food items.

3.     Data Centers

Since data centers contain numerous servers that operate 24/7, keeping those servers from overheating is necessary which is why commercial air conditioning units are a critical part of the IT industry.


4.     Hospitals and Clinics

Some medicines and vaccines need to be stored in cool temperatures so that they will retain their efficacy which is why temperature and humidity control in health services are important. Commercial air conditioning systems not only prevent the medicines from losing quality but also ensure the comfort of the patients.


5.     Flower Shops

Cut flowers need to be kept in a specific humidity and temperature to retain their quality and freshness longer which is why commercial air conditioning systems are critical to mimic the flowers natural habitat while preventing spoilage, rot or damage.


6.     Museums and Art Galleries

Valuable works of art may become damaged over time if left in the natural environment. Changes and temperature and humidity levels affect the quality of the artworks which can be prevented with the presence of commercial air conditioning systems.

7.     Server Rooms and Manufacturing Facilities

Server rooms in manufacturing facilities keep the operation functioning efficiently but overheating may cause disruptions that affect the flow of the operation. Commercial air conditioning keeps the server room at an ideal temperature to ensure that the servers do not overheat and affect the operations.



Factors to Consider When Choosing the Right Commercial Air Conditioning System for Your Business:

Selecting the ideal commercial air conditioning system entails more than just controlling the temperature. Consider these crucial factors to ensure you select the best option for your business:


1.     Building Size and Layout

The building size and the area of operation should be considered to determine the required cooling capacity. A small air conditioning system will not be able to provide adequate cooling while an oversized one will just increase your energy consumption. Refer to the layout of the building to identify if what you need is a single large system or multiple systems for more individualized control.


2.     The Number of Occupants

 Aside from the area of the building or office, you should also determine the number of employees or occupants because as a general rule, the more people there are, the stronger the air conditioning system must be.


3.     Desired Features

You may consider various features such as variable speed drives or heat recovery for reduced energy costs or zoning control for individual temperature adjustments for different area. There are more features like simultaneous heating and cooling systems. Choose the one that fits your business style.

4.     Budget

Commercial air conditioning systems vary in size, features, and price. Set a budget and choose the feature that is suitable for your business needs. Do not always opt for the one with the best features, rather, opt for the one that can provide you with the best efficiency and effectiveness.  Always ask for quotations and compare prices from different suppliers to make the most out of your budget.


5.     Consider the Climate

The climate in your region is one the most important things to consider because warm weather and climates need a more robust system than colder ones. For areas with high humidity levels, choose a system with dehumidification functions while for colder climates, choose a system that has a heating function.


6.     Building Codes and Requirements

Existing building codes, rules, and regulations should always be followed. Always check with the authorities to ensure that no rules are being broken before choosing the air conditioning system.

Building Codes and Requirements




Commercial air conditioning systems provide various advantages for businesses and infrastructures. The system is versatile in a way that it can cater to different industries while being designed as a heavy-duty alternative for residential air conditioning units. The factors stated above should help you choose the appropriate system for your needs. Always remember that the best air conditioning system is the one that works efficiently and effectively.
