Some people run their AC system while leaving their windows open to let in fresh air.
This is a bad idea for a number of reasons.

You Wear Down Your AC Unit

Is It Bad To Leave My Windows Open When I Have My AC On?Leaving your windows open results in your AC system needing to run continuously, dramatically shortening its lifespan. AC systems are installed with a load in mind related to the size of your home. When you leave windows open, you increase the load. Your AC system has to work much harder to maintain the temperature you set on the thermostat as cool air escapes out the open windows.

Dust Enters Your Home

When you leave a window open while running your AC system, dust comes into your home and then enters the return register. The dust clogs up your system’s air filter and can end up covering the evaporator coil. You’ll need to change air filters more often as otherwise, your system will have to work much harder to cool your home. A dust-covered evaporator coil results in a slowed cooling process, which ends up increasing your energy bills.

Open Window Alternatives

Rather than leaving windows open to bring in fresh air, you’re better off having an energy or heat recovery ventilator installed in your home. These ventilators draw in fresh air while expelling stale air without losing the indoor air’s temperature. While these ventilators use electricity, it’s a far smaller amount than what it costs to leave your windows open while running the air conditioner.
