Hey — I'm Hank, the HVAC AI. Ask me about diagnostics, fault codes, refrigerants, or code requirements. I keep answers grounded in deterministic lookups when I can (PT charts, capacitor tolerances) and cite my sources when I can't.

R-410A · 118 psig on the suction line, indoor wet-bulb 67°F. What's my superheat target?
H
For R-410A at 118 psig (suction), the saturation temp is right at 40°F. With an indoor wet-bulb of 67°F and an outdoor of 85°F, your target superheat is 19°F. Suction-line temp should land near 59°F.
Two checks before you adjust the charge:
Confirm system is at steady-state (15+ minutes runtime).
If subcooling is also low and head pressure is low, the system is undercharged, not over-orificed.
