How to lower the cost of running a window air conditioner

Window air conditioners cool a single room and are far cheaper to run than central AC when you only need one or two rooms cool. Wattage scales with capacity: small 5,000 BTU units draw around 450–500W, a 10,000 BTU unit around 900W, and large 15,000+ BTU units 1,300–1,500W. ENERGY STAR models with inverter compressors can use 20–35% less. The compressor cycles with the thermostat, so enter the hours it actually runs.

  • Pick the right size — an oversized unit cycles constantly and dehumidifies poorly.
  • Seal the gaps around the unit with foam strips to keep hot air out.
  • Clean the washable filter every two weeks in peak season.
  • Summers in Nebraska are relatively mild, so cooling costs are concentrated in a few hot weeks each year.
