Refrigerant shortage (low suction pressure)

Likely causes

Leak (flare joints, valve packing, weld points)

Check: Measure low-side pressure — confirm normal range for refrigerant type

What to do: Measure low-side pressure — confirm normal range for refrigerant type → Inspect all piping for leaks (electronic detector or soapy water) → Repair leak (re-flare or weld) → Evacuate system and recharge to specified amount → After charging, confirm bubbles disappear from sight glass

Natural reduction from long-term lack of inspection

Check: Inspect all piping for leaks (electronic detector or soapy water)

What to do: Inspect all piping for leaks (electronic detector or soapy water) → Repair leak (re-flare or weld) → Evacuate system and recharge to specified amount → After charging, confirm bubbles disappear from sight glass

Insufficient charge after service work

Check: Repair leak (re-flare or weld)

What to do: Repair leak (re-flare or weld) → Evacuate system and recharge to specified amount → After charging, confirm bubbles disappear from sight glass

Field tip

Never add refrigerant without first repairing the leak
