A lot of people have bought crappy AC to help cope with the five to ten days of heatwave a year. They're not running often.

I've been running mine for about a month. Depends on your house, how much it traps heat, etc.

Really it's besides the point - you might not need a plunger to unclog the toilet or a fire extinguisher or a first aid kit often, but when you do, you really need it!
