Get an EEV Open (Like Magic)
Most ductless systems and some high efficiency unitary systems have electronic expansion valves.
If you find one that is stuck closed you may be able to get it open temporarily by putting a strong magnet on the valve body and turning it counter clockwise.
This is likely only temporary so valve replacement is still a good idea but it can help get the customer running while you wait to get a part.
Pretty cool Ulises.
