How to Fix Your Air Conditioning When It Won’t Turn On

When the scorching heat of summer hits, having a functioning air conditioning system is crucial for staying comfortable indoors. However, it can be incredibly frustrating if your air conditioning won’t turn on, leaving you sweating and uncomfortable. If you’re experiencing this issue, don’t worry. With a few troubleshooting steps, you can often identify and resolve the problem without needing to call for professional air conditioning repair services.

Fix Your Air Conditioning

Check the Thermostat

One of the first things to do if your air conditioning won’t turn on is to check the thermostat. Sometimes, the issue may simply be that the thermostat is not set correctly or has malfunctioned. Make sure the thermostat is set to “cool” and that the temperature setting is lower than the current room temperature. If the thermostat clicks but no AC still turn on, try replacing the batteries if it’s a battery-operated unit.

Inspect the Circuit Breaker

If the thermostat seems to be working fine, the next step is to check the circuit breaker. A tripped circuit breaker can prevent your air conditioning system from receiving power. Locate your home’s electrical panel and check if the breaker corresponding to the air conditioning unit has tripped. If it has, reset it by switching it off and then back on.

Listen for Clicking Sounds

Sometimes, you might hear a clicking sound coming from your thermostat when you try to turn on the air conditioning. This could indicate that there is power reaching the unit but that it’s not turning on properly. If you hear clicking but the air conditioning still won’t start, there may be an issue with the compressor or another component of the system. In this case, it’s best to contact a professional for air conditioning repair.

Inspect the Air Filter

A dirty or clogged air filter can restrict airflow to your air conditioning system, causing it to malfunction. Check the air filter and replace it if it appears dirty or clogged. A clean air filter not only improves air quality but also helps your air conditioning system operate more efficiently.

Check the Outdoor Unit

If none of the above steps resolve the issue and your air conditioning still won’t turn on, it’s time to check the outdoor unit. Make sure it’s not blocked by debris such as leaves, branches, or dirt. Clear away any obstructions that could be hindering airflow to the unit. Additionally, check for any visible signs of damage or corrosion on the outdoor unit’s components.

Call for Professional Assistance

If you’ve tried the troubleshooting steps above and your air conditioning still won’t turn on, it’s time to call in the professionals. A certified HVAC technician will have the expertise and tools necessary to diagnose and repair the problem quickly and effectively. They can identify issues such as faulty wiring, a malfunctioning compressor, or low refrigerant levels that require specialized knowledge and equipment to address.


Dealing with a malfunctioning air conditioning system can be frustrating, especially during the hot summer months. However, by following these simple troubleshooting steps, you can often identify and resolve the issue without needing to call for professional help. Remember to check the thermostat, circuit breaker, air filter, and outdoor unit before seeking assistance from an air conditioning repair technician. With a little patience and know-how, you can have your air conditioning up and running again in no time, keeping your home cool and comfortable.
