HVAC stopped working? Before you panic, there are a few quick things you can check.
First, check your thermostat and make sure it’s turned on. Then switch the fan from Auto to Fan to see if it’s running.
Next, head outside and take a look at your condensing unit. If the outdoor fan is running, that information can help our technicians know where to start troubleshooting when they arrive.
