It must be one of the hottest days of the year. You go to turn the air conditioning on and…nothing. There’s no cool air, warm air, or even any air at all. Though an air conditioning unit that goes on the fritz isn’t as worrisome as a heater that dies in the dead of winter, it can still leave your household uncomfortable and have every member scrambling for some kind of electric fan. Before you call our air conditioning experts at Summit Heating & A/C in Denver, though, here are some things you can do:

Check to See If the Unit Is Plugged In

Sometimes, the unit doesn’t work because it is not plugged in. This isn’t a cause for embarrassment. The unit may have been unplugged because it was serviced or something had to be checked, and the person simply forgot to plug it back in.

Check the Electrical Panel

Depending on their age, homes either have fuse boxes or circuit breakers. You should check your panel, and if the fuse that operates the air conditioning has blown, replace it. If your house has a circuit breaker and it has been tripped, switch it from “off” to “on.” Some outdoor air conditioning units also have a shut-off box nearby. If the fuse is blown here, it should be replaced.

Check the Thermostat

An air conditioner that won’t work because something is wrong with the thermostat is a common issue. First, check the thermostat, and make sure it is in “cool” mode. Then, set the temperature no less than 5 degrees beneath the room temperature.

Check the Filter

A clogged filter can prompt the air conditioning unit to shut down. Make sure the filter is clean or exchange it for a new one. A good rule of thumb is to change the filter every three months or so.
