Commercial Chiller Services in Greater Los Angeles

Avoid Downtime. Protect Your Operation.

Chillers support key building systems. When they fail, operations stop. That can mean lost product, system errors, or serious delays. Reliable service keeps your system online.

We repair, install, and maintain commercial chillers for office buildings, manufacturing plants, hospitals, and data centers throughout Southern California.

How Is a Chiller Serviced?

Service includes a complete check of all system components. That means cleaning coils and tubes, testing refrigerant pressure, calibrating sensors, and confirming control panel settings. On water-cooled chillers, we inspect tower operation, water treatment quality, and pump flow.

The goal is to maintain steady performance and prevent costly shutdowns.

What Types of Chillers Do We Service?

• Air-cooled chillers
  Mounted on rooftops or outside the building. Use ambient air for cooling.
• Water-cooled chillers
  Used in larger buildings with cooling towers. Require water flow and tower support.
• Centrifugal chillers
  Built for high-load settings like hospitals or campuses.
• Scroll chillers
  Used in smaller setups, often for light manufacturing or server room cooling.
• Reciprocating chillers
  Common in moderate-load environments. Reliable for basic building cooling.
• Rotary screw chillers
  Found in continuous-use operations like food production or industrial sites.

We inspect, repair, and help maintain all major chiller types.

FAQ: Chiller Service

How is a chiller serviced?
Technicians inspect, clean, and test the system. That includes refrigerant levels, coil condition, sensors, and pressure checks.

How often should a commercial chiller be maintained?
Most systems should be serviced every 3 to 4 months. High-demand or critical setups may need more frequent visits.

What’s the difference between air- and water-cooled chillers?
Air-cooled units use fans and refrigerants to reject heat. Water-cooled systems use towers and pumps to transfer heat through water loops.

Can you repair older chiller models?
Yes. We work on legacy systems and can help plan replacements if needed.
