Power Stations

[Sneakers]

However, I did get some really good data points an power usage. The window inverter a/c used 2.9kWh of power on Friday, and 2.8kWh on Sat, two days of keeping the living area at 76* day and night with outside temps in the high 80s / low 90s during the day for 5.7kWhs of use. The central air uses 5.4kW to turn on, and about 4kW to run. Ignoring the turn-on surge, that 4kWh for every hour it runs. If it were running 40% of the time on a hot day, that's 9.6 hours at 4kW = 38.4kWh x 2 days = 76.8kWh.

76.8 kWh vs 5.7 kWh to stay comfortable. The window a/c pays for itself easily.

So far, really impressed with this inverter a/c. I have it set to 75* now 24/7 and it keeps the "living area" (family room, bedroom, bathroom, den) very comfortable, and is hardly working to do it. So quiet, too, barely hear it running. The central a/c is set to 85* and only runs in the afternoon into the evening, and only infrequently, basically just to keep the humidity down. If the central a/c were the only thing running, it would be running just about non-stop in these high temps. Looking forward (ok, not really...) to the SMECO bill. I'm using far far less electric to run the window unit than central.

Down side - doesn't dehumidify as much as I would like. Averages about 65%, would like about 50-55%. This unit has also been recalled for mold accumulation. It holds water in a pan and splashes it up onto the coils to provide additional cooling. The water sits and mold can grow. I removed the drain plugs on the bottom so it doesn't retain water.
