Sizing disclaimer.
Planning estimates need a qualified professional assessment.
A planning estimate needs a professional check.
Every tool simplifies real conditions. The displayed range can be too small or too large for your actual home. It is not an engineering design, equipment specification, code assessment or installation instruction.
HVAC needs a qualified room-by-room load calculation and equipment/duct selection. Generators need actual simultaneous loads, motor startup, fuel ratings and safe transfer equipment. Water heating needs measured demand and manufacturer performance. Solar needs a roof, electrical, utility and production assessment. Dehumidifiers cannot repair moisture entry.
A licensed contractor must confirm final sizing and installation. Electrical work needs a licensed electrician. Follow manufacturer instructions and the locally adopted requirements.
Critical backup power.
The medical-equipment preset excludes the medical device itself. This tool cannot assess power quality, continuity, runtime or life-support reliability. Arrange an approved backup plan with the device provider and qualified professionals.
