Air conditioners are complex appliances with many working components. When the system won’t turn on at all, there are three different areas we check first.

1. A Malfunctioning Thermostat

Your air conditioning system takes commands from the thermostat. When the thermostat breaks, your air conditioner doesn’t know there’s anything it should be doing. One sign that the issue may be your thermostat is if the display screen on your air conditioner is blank. You can try to turn the switch on the display or change the temperature buttons to see if this lights the screen up. Another easy fix would be if the batteries on the display are dead, you can replace the batteries and see if that lights the display up. If these simple tricks don’t work, it likely means you need a new thermostat. This is a task you’ll need a professional HVAC technician to handle for you as it could be an electrical issue. Your technician will inspect the thermostat, replace it if it’s broken, and then calibrate the system to ensure it’s working before they leave.

2. A Clogged Filter

Your system’s air filter catches dirt and debris, improving your home’s air quality. These filters need changing as part of a regular maintenance program. When this doesn’t happen, the filters can build up dust and become clogged. The cold air circulates inside the unit, becoming very cold, and can cause the air conditioner’s coils to freeze up. The unit will then refuse to turn on.

In this case, turn the air conditioner off. It would be best to have an experienced HVAC technician handle the repair because this will be a multi-step process. Your technician will change the filter, clean other areas that may have fallen into ill repair due to the clog, and repair the coils.

3. Your Air Conditioner Isn’t Getting Power

Sometimes, this may be as simple as a cord coming unplugged or a power switch in your home switched off. Another common issue is a tripped circuit breaker in your home. The main electrical panel for your home will show the tripped breaker.

If the issue is with the air conditioner then it is likely that your outside air conditioning unit has blown a fuse. A professional technician will safely take apart the unit and replace the electrical component.
