What is a chiller and how does it work?

A chiller is a machine that removes heat from a liquid via a vapor-compression or absorption refrigeration cycle. This liquid can then be circulated through a heat exchanger to cool equipment, or another process stream (such as air or water).

How often should you service your chiller?

Industry standard is once per year, but based on use and environment, more frequent servicing may be necessary.

What are the benefits of servicing your chiller?

• Extend the life of your equipment: Proper maintenance can identify potential issues before they cause damage or breakage.
• Improve efficiency: A well-maintained chiller uses less energy, saving you money on your energy bill.
• Reduce downtime: Regular servicing can help prevent unplanned downtime due to equipment failure.

What to look for when getting your chiller serviced:

• Check the refrigerant level and make sure it is topped off: This should be done every few months as part of routine maintenance, but if you notice your chiller isn’t cooling as efficiently as it used to, this could be the reason why.
• Inspect the air filters and clean or replace them as needed: Dirty air filters can restrict airflow and cause the evaporator coils to freeze up, which reduces the chiller’s efficiency.
• Check the condenser coils for dirt and debris: If the coils are dirty, they won’t be able to reject heat properly and the compressor will have to work harder, leading to higher energy bills.
• Inspect the evaporator coils for ice buildup: Ice buildup on the coils can also restrict airflow and reduce efficiency. In severe cases, it can cause the compressor to overheat and shut down.
• Check the expansion valve for dirt or debris: The expansion valve regulates the flow of refrigerant into the evaporator coils, and if it becomes dirty or blocked, it can cause major problems.
• Inspect the condensate drain line: The condensate drain line carries water away from the condenser coils, and if it becomes clogged, water can back up and damage the coils.
• Check the float switch: The float switch is a safety device that shuts off the power to the compressor if the condensate level gets too high. If it isn’t working properly, your chiller could be at risk of flooding.
• Listen for strange noises: Any strange noises coming from your chiller should be investigated as they could indicate a problem with one of the compressors or other components.
• Check the electrical components: The compressor and other electrical components in your chiller are under a lot of stress, and if any of them are showing signs of wear, they should be replaced before they fail.
• Have a professional check for leaks: Leaks can cause the refrigerant level to drop, which reduces efficiency and can damage the compressor. A professional will be able to find and repair any leaks quickly.

Now that you know what to look for when getting your chiller serviced, you can be sure that your equipment is running efficiently and safely. Be sure to follow these tips and schedule a service appointment today!
