Making sure the TXV is metering the right amount of refrigerant into the evaporator and is not overfeeding the coil is one way technicians can help their customers’ refrigeration and air conditioning systems operate safely and more efficiently.

Technicians should pull the necessary vacuum to ensure the system they are working on is properly evacuated.

Washington state is currently figuring out how to implement legislation that establishes maximum GWP thresholds for HFC refrigerants used in new stationary refrigeration and air conditioning equipment.

Liquid line restrictions cause the evaporator, compressor, and condenser to be starved of refrigerant, causing performance problems in refrigeration systems.

Locating the source of a refrigerant leak in a self-contained reach-in cooler or freezer and repairing it may be difficult, but technicians should always attempt to find the source.

An evaporator can be cold but inactive, causing warm refrigerated space temperatures.

Prices of HFCs are increasing, which makes leak detection and mitigation an important strategy for food retailers.

There’s nothing better than a comfortable, air conditioned home during summer. Unfortunately, that may be in jeopardy, as electric grid operators around the country warn of possible shortages.

When adding refrigerant to a refrigeration system, there are several different methods a technician can use to determine the correct amount needed.

The condenser is the most underrated component in an air conditioning or refrigeration system.
