How long should it take for my AC compressor to kick on?

Answered by Jeremy Urbaniak

When it comes to air conditioners, the time it takes for the compressor to kick on can vary depending on a few factors. Generally, it should take anywhere from a few seconds to a few minutes for the compressor to start running once you turn on your AC.

In my experience, I’ve noticed that newer air conditioners tend to start up faster than older ones. This is because newer models often have more advanced technology and are designed to be more efficient. So if you have an older AC unit, it might take a bit longer for the compressor to kick on.

Additionally, the temperature setting on your thermostat can also affect how long it takes for the compressor to start. If you have set your thermostat to a very low temperature, the compressor may take a little longer to start as it needs to work harder to reach that temperature. On the other hand, if you have set the thermostat to a moderate temperature, the compressor may start up more quickly.

In the case of a power outage or a reset, it’s normal for the air conditioner to take a little longer to start up. This is because the system needs to go through a reboot process and regain its settings. Usually, it should take around 1-2 minutes for the compressor to kick on after a power outage or reset. However, if it’s taking longer than that, there could be an issue with the thermostat.

If your air conditioner won’t turn on at all and the compressor is not starting, it’s best to check the thermostat first. Make sure it is set correctly and the batteries are not dead. If everything seems fine with the thermostat, then there might be a more serious problem with the AC unit itself, such as a faulty motor or a refrigerant leak. In these cases, it’s advisable to contact a professional technician to diagnose and fix the issue.

To summarize, the time it takes for your AC compressor to kick on can vary depending on the age of your unit, the temperature setting, and whether there was a power outage or reset. Generally, it should take a few seconds to a few minutes. If it’s taking longer or the compressor is not starting at all, there may be a problem with the thermostat or the AC unit itself.
