Preserve the useful detail
Measure room volume, clearances, air or duct path, condensate route, panel capacity, access, household demand, and nearby rooms.
The decision on display
Do not transfer the hazard
Use current manufacturer, permit, and incentive documents. Do not promise a rebate, savings, or recovery performance.
Make the proposed work comparable
Require model and sizing, circuit, condensate, pan, ducting, restraint, valves, permit, commissioning, modes, instructions, and haul-away.
