Chiller Overview

Chillers are essential devices used to cool liquids, typically water, in a variety of applications. They work by extracting heat from the liquid and transferring it to a separate medium, such as the surrounding air or another water loop. Chillers utilize refrigeration cycles, often based on vapor-compression or absorption, to achieve the cooling process.

By maintaining a specific temperature, chillers enable efficient cooling for air conditioning systems in buildings, industrial processes, refrigeration systems, and more. They play a vital role in ensuring comfortable and controlled environments while supporting the proper functioning of numerous industries and processes.

R&R does not only service chiller systems. We provide a full installation - from estimating to the installation and removal of an existing system. R&R has been in the business since 1958 and our expertise in fit and finish will meet your expectations.

How Can We Help?

Repair and Troubleshooting

In case of chiller malfunctions or breakdowns, skilled technicians can diagnose the issue, perform repairs, and replace faulty components to restore functionality.

Retrofit and Upgrades

Upgrading existing chillers or retrofitting them with newer and more efficient components can improve performance, energy efficiency, and reliability.

Refrigerant Recharging

If a chiller's refrigerant levels are low, technicians can recharge the system with the appropriate refrigerant to ensure efficient cooling.


Professional installation of chillers ensures proper placement, connection to the system, and integration with other HVAC components.

Cleaning and De-scaling

Over time, chillers can accumulate scale, sediment, or biological growth, which can impact efficiency and performance. Professional cleaning and de-scaling services help remove these deposits and maintain optimal operation.

System Upkeep and Monitoring

Ongoing monitoring and regular check-ups can help identify potential issues early on, prevent major failures, and ensure the chiller operates at peak performance.

Preventive Maintenance

Regular maintenance is crucial to keep chillers in optimal working condition. This includes inspecting and cleaning components, checking refrigerant levels, lubricating moving parts, and verifying electrical connections.

Performance Optimization

Chiller service providers may analyze the chiller's performance through data logging, monitoring, and analysis. They can identify opportunities for optimization, such as adjusting control settings, improving water flow, or enhancing system integration.
