Chiller Service

Saving Time and Money on Complex Mechanical Systems

Few mechanical service companies have reliable technicians who work on complex chiller systems. When a chiller emergency strikes, you need a dependable partner to get you back up and running. We’re available 24/7 for all your service needs.

Dean E. Norris, Inc. experienced technicians respond quickly so you minimize downtime and keep operations moving smoothly.

  • Fewer breakdowns
  • Increased efficiency of system reducing your energy consumption
  • Longer equipment life
  • Lower operational costs

Chillers Service Includes (not limited to):


Our knowledgeable technicians check all components for wear or damage, especially belt tension and reservoir water levels. As spring and warmer weather approaches, we check that pads are being uniformly wetter to set up the system for improved cooling efficiency.

Tube Brushing

Mud, sand, algae, and hard mineral scales increase thermal resistance and cause chillers to work harder, which consumes more energy.  Most chillers have several miles of condenser and evaporator tubing, so our technicians keep these chiller tubes as clean as possible to help you save money.

Oil Analysis

Technicians determine where the chiller is experiencing a harmful problem, if there is an oil breakdown, or if contaminants are affecting performance.

Oil Change

Oil changes reduce downtime, minimize costly repairs, and extend your chiller’s life.

Vibration Analysis

Technicians repair, align and balance to get peak chiller performance.

Refrigerant Analysis

We adhere to Air Conditioning and Refrigeration Institute (ARI) standards to test acidity, moisture, oxides, and percent oil, so your chiller is operating at design specifications or better.

Eddy Current Testing

This cost-effective, non-destructive testing determines the condition of condenser and evaporator tubes by measuring the remaining wall thickness of tubes and detecting pitting, cracks and bulges that can result in tube leaks.

Power Washing Condenser Coils

Keep condenser coils clean to reduce downtime and costly chiller breakdowns.
