Estimate monthly AC energy and cost from average electrical input, daily runtime, load factor and electricity rate.
Results are for information and preliminary estimation. For critical technical work, manufacturer data, local codes and qualified professional review take precedence.
Monthly energy ≈ electrical input (kW) × daily hours × days × average load factor. Inverter AC input varies continuously, so this is a scenario estimate.
A 1.1 kW average input used 8 hours/day at a 60% load factor uses about 158.4 kWh over 30 days.
HVAC capacity depends on more than floor area. Volume, solar gain, insulation, glazing, occupants and equipment loads all matter; critical selections require a proper heat-load assessment.
No. BTU/h is thermal capacity; electrical input depends on equipment efficiency.
The compressor modulates speed to match demand, so the average load factor strongly affects consumption.
What AC capacity does my room need?
→How many kW or tons of cooling is a BTU/h rating?
→How much airflow does a room need in m³/h?
→How much electricity does a heat pump use for a given heat load?
