What to note
Measure room area in sq ft, note ceiling height, sun exposure, shade, window direction, typical occupancy, and heat-producing appliances.
Room Assessment
Start with the room before choosing equipment.
Use this path to collect the practical inputs that shape AC sizing: sq ft, ceiling height, window exposure, insulation, occupancy, appliance heat, and operating hours.
What to verify
For permanent equipment, ask a qualified HVAC professional how they calculated BTU/h, airflow, ductwork, placement, and humidity control.
