Variable Frequency Drive — controls motor speed to save energy. Affects CT sizing and baseline modeling.
VFD present — CT and power measurements may need special consideration.

Sensor Accessibility
Can you reach the supply air plenum downstream of the coil to mount a wireless sensor?
Can you reach the return air path upstream of the coil?
Subcooling & Refrigerant Access
Thinner of the two copper lines at the condenser, carrying warm high-pressure refrigerant to the evaporator. Best spot: right at the condenser outlet. Sensor needs ~3 inches of exposed bare copper (no insulation or paint) to strap onto.
Used to measure saturated condensing temperature. Ideal spot: a return bend ~1/3 to 1/2 down the condenser coil where refrigerant is actively condensing. Second best: the hot gas discharge line right where it enters the top of the condenser. Needs ~3 inches of exposed bare copper to strap onto.
Small brass valve (like a tire valve) on the refrigerant lines near the compressor. Usually two of them — low-side on the suction line, high-side on the liquid or discharge line. Often capped.
Cold Environment
Helps plan gateway placement for wireless sensor range.
Diameter of chilled water supply/return piping for future flow meter sizing.
