Refrigerant Analysis

Advantages of Refrigerant Analysis

  • Measurable Cost Savings - Proper identification of problems in refrigeration systems helps you avoid costly equipment failures, as well as reductions in energy efficiency.
  • Robust and Versatile - MRT provides information on key refrigerant characteristics, all carried out according to AHRI-specified methods, with 24-hour and expedited turn-around service available to all customers.

Refrigerants must be closely monitored to ensure they are not degrading. Excess water, lube oil contamination, and acidity are all common, but potentially serious, problems seen in any refrigeration unit. These problems are often intertwined, as excess water allowed to persist in a refrigerant will eventually create highly corrosive organic and inorganic acids. These acids can cause significant damage to a refrigeration system, resulting in costly maintenance.

High acidity can also be a strong indicator of compressor burnout, as the high temperatures generated in these conditions greatly accelerate acidic build-up. Refrigerant analysis is particularly useful when the refrigeration oil is tested in tandem, as this can provide vital information on the root cause of any detected issues.

We offer an in-house Standard Test Package of refrigerant analysis which includes four of the seven tests in the AHRI 700 slate, which is the most widely utilized test slate to certify new and recycled refrigerant. Our Standard Test Package accommodates our commercial HVAC maintenance clients who test in-service refrigerants on a semi-annual basis.
