Types of Air Conditioning Systems

Aug 30, 2023 | HVAC

Air conditioning is crucial for Texans in the summer. Not only is the Texas heat uncomfortable, but it’s also dangerous for employees. Having the right type of air conditioning system in your commercial building is crucial for employees’ comfort and safety.

At CS Mechanical, we understand the importance of having the right air conditioning system in your commercial building. Our technicians have experience with a variety of models that include the following. Here’s a look at some common air conditioning systems we often install in facilities.

Central Air Conditioning

Central air conditioning uses a system of ductwork to move air throughout the building. It combines supply and return ducts to spread conditioned air and return it to the system. Along with producing cooler air, central air conditioning units also remove moisture from the air.

Reducing air moisture is crucial for everyone’s comfort during hot, humid summers.

We often recommend this air conditioning system for our clients with smaller commercial buildings.

Ductless, Mini-Split Air Conditioner

Buildings with smaller, enclosed areas often use ductless, mini-split air conditioners. The system typically uses a single outside and indoor unit connected by electric cables and refrigerant tubing.

The interior unit is mounted on a wall or placed in a window space to produce warm or cool air.

These types of air conditioning systems eliminate the need for ductwork. However, the system is often more expensive than a central air conditioning unit. Businesses can save money on installation costs since ductwork is not necessary.

Disadvantages of Mini Split Systems

Our technicians will recommend the best solution and highlight its advantages and disadvantages. As we noted earlier, mini-split systems are ideal in enclosed rooms. However, the system cannot cool or heat larger, open spaces. The costs associated with purchasing enough units to adequately condition the air are often too prohibitive for smaller company budgets.

Multi Split Air Conditioner

Multi-split air conditioning systems are similar to mini-split units. The primary difference is the ability to connect multiple indoor units to a single one outside. We often recommend this type of air conditioning system for businesses, restaurants, and offices with open spaces. Since only one outside unit is required, a multi-split air conditioning system doesn’t detract from the building’s aesthetics.


VRF (variable refrigerant flow) and VRV systems are typically employed in larger buildings. For example, large workplaces, hotels, and retail centers.

Using a combination of heat pumps and recovery systems, the units can send conditioned air to large, open spaces or multiple rooms simultaneously. Using the heat recovery system, these systems can also heat one area and cool another during a single cycle.


We can install all types of chillers. After inspecting your commercial building, we recommend the best system to meet your needs.

Air-cooler chillers use a heat exchanger to remove heat from the atmosphere. Water-cooler chillers are another option. Often less expensive than air-cooler chillers, these systems use a refrigerant stored in a cooling tower to produce cool air.

In mid-sized and larger buildings, we may recommend an absorption chiller. A type of water-cooled chiller, it is energy-efficient and works with your central air conditioning system.

Outdoor HVAC Unit

Outdoor HVAC units are often the most commonly used type of air conditioning system found in large commercial buildings. The unit is often installed on the roof but can also be located on the ground.

The system removes heat from the indoor air and transfers it to the refrigerant. From there, the air is sent to the outdoor HVAC unit and into the building.


What are building automation systems in HVAC?

A building automation system (BAS) is a network connecting a building’s utilities into a centralized location. It allows you to control the HVAC system remotely using a connected device.

How often should a home have its HVAC system replaced?

We follow the Department of Energy’s guidelines and recommend replacing your HVAC system every ten years. Some HVAC systems can function optimally for 15 years or more with proper maintenance.

What is involved in HVAC maintenance?

When you schedule HVAC maintenance with CS Mechanical, you can expect our experienced technicians to perform a thorough inspection. We will replace the filters and clean the evaporator and condenser coils. We also lubricate any moving parts and perform safety and operational tests.

What is the proper tonnage per square foot for HVAC?

We recommend an average of one ton of cooling capacity for every 1000 sq. ft. of office space.
