I’m juggling a 24 fan-coil VRF retrofit in a 3-story building next month and, as the GC/HVAC lead, I need a practical commissioning checklist that keeps HVAC, electrical, and controls on the same page. If you’ve got a phone-friendly template or daily start-up log techs use, I’ll swap our punch list and homeowner handoff packet that cut callbacks about 30%.
I use a QR-coded Google Form per fan coil so HVAC, electrical, and controls all sign the same phone checklist; required fields cover vacuum microns/hold, phase/voltage, comm address, condensate test, and BMS point-to-point. Top line reads “no power, no comms, no refrigerant” so charging can’t start early — treat it like a pre-flight so nobody plays thermostat roulette. If cell service is spotty, print the QR and carry a one-page paper backup.
Quick example from a 24‑FCU VRF: we use a one-screen ‘Daily Start‑Up Card’ in Notes — each coil needs a micron screenshot after a 10‑minute hold, a pic of L1‑L2‑L3 at the ODU, and the comm address label on the panel before power-up; keeps subs marching to the same beat without another app. If cell service is trash, we mirror it on a laminated card and upload pics later; @KaraControls could drop a trend‑point stub so controls can verify EEVC/thermistor sanity during the walk.
