Unit: Heatcraft LET090BK — Walk-in Cooler
Suction pressure is reading 18 psi on R-448A, superheat at 22°F
AId
That superheat is high for this unit. With 18 psi suction on R-448A, sat temp is about 8°F. At a target SH of 10-12°F, you likely have a restricted TXV or low charge. Check the sight glass — any bubbles?
Yeah, bubbles in the sight glass
AId
Low charge confirmed. Check for leaks at the common spots — flare fittings, schraders, evap U-bends. Want me to start a parts request for R-448A?

Everything a tech needs. Nothing they don't.

Built from years in the field, not a boardroom. Every feature solves a real problem techs face every day.

This wasn't designed by software people guessing what technicians need. It was designed by a journeyman technician who's tired of the same problems every tech faces — the paperwork, the phone calls, the time wasted not turning wrenches.
