My handyman told me this happens when tenants put light bulbs in sockets that have too high a wattage for the lamp. 

The kits include compact fluorescent light bulbs of various wattages, LED night lights, smart power strip, whistle that attaches to your HVAC air filter and alerts you when it's time to change the filter, low flow shower heads, dryer vent cleaning brush, water temperature thermometer, refrigerator thermometer, weatherstripping, caulking, foam pipe insulators, window film, rain gauges, etc.

Also, that figure would be for the compressor and fan combined, need to estimate a "duty" cycle for the compressor which utilizes most of the wattage, but only when it is operating.
