If your air conditioner won’t turn on, it’s probably because something is preventing it from getting power. Maybe a circuit breaker has tripped, or a fuse has blown. Or, it could be something more serious, like a compressor failure.

In any case, you’ll need to troubleshoot the problem to determine what’s causing it. This article will show you how to do that.

  1. Check the thermostat settings: First, make sure that the thermostat is set to “cool” and that the temperature setting is lower than the current room temperature. If both of these things are true, then the problem is likely with the air conditioner itself and not the thermostat.
  2. Check the power: Next, check to see if the air conditioner is getting power. This can be done by checking the circuit breaker or fuse box. If the unit’s breaker has slipped, reorganize it and see if that resolves the issue. But, if you are finding the fuse blown, you’ll need to replace it with a new one.
  3. Check for obstructions: Another possible reason why your air conditioner isn’t turning on is that something is blocking the airflow. This could be a piece of furniture, a curtain, or anything else that’s preventing air from flowing freely around the unit.
  4. Check the filters: Dirty or clogged filters can also prevent your air conditioner from turning on. Try removing and cleaning the filters, and then see if the unit will start up.
  5. Check for leaks: Check for any leaks in the air conditioner’s ductwork. If there are any, they’ll need to be repaired before the unit will work properly.
  6. Check whether the HVAC unit’s switches are in the right position: If your air conditioner is still not turning on, then it’s possible that the unit’s switches are not in the correct position. The switches should be in the “on” position for both the furnace and the air conditioner. If they’re not, then simply flip them to the “on” position and see if that solves the problem.

Conclusion:

If your air conditioner won’t turn on, don’t panic. There are several possible reasons why this could be happening, and most of them are relatively easy to fix. Just follow the troubleshooting tips in this article, and you should be able to get your AC unit up and running again in no time.
