@acservicetech: Craig & @love2hvactalk about EEV (Electric Expansion Valves), discuss their role in HVAC systems like mini split units, and give an up-close demonstration of how an EEV opens and closes to allow refrigerant into a system! Watch the full video on YouTube by looking up, "HVAC Metering Device Types: EEV, TXV, TEV, Piston, Capillary Tubing! Function, Location, Problems!" . . . #hvac #hvacr #hvactech #technician #hvacservice #hvacrepair #hvactraining #hvaclife #acservice #acservicetech #minisplit #mini #hvactechnician #EEV #expansionvalve #meteringdevice #demonstration #refrigerant #watch #youtube

The piston was the best metering device - never had problems.

making things electronic doesn't always mean that it's better. I was always taught, if it isn't broken don't fix it.

Great untill a sensor fails or the evc board fails then closes the valve. Piston was fine and better for the consumer.

Everything is becoming more and more electronic to become more efficient but it’s less efficient when all these parts fail

more failures will happen now do to the circuit board. This is why the systems don't last as long anymore OEM parts will not be available because the unit will be out dated by the time it's installed .
