Beat the Heat: What to Do if the Air Conditioner is Not Working?


As the temperatures rise, a malfunctioning air conditioner can quickly turn your home into an uncomfortable sauna. In this blog, we’ll guide you through a step-by-step process on what to do if your air conditioner is not working, helping you troubleshoot common issues and restore the cool comfort you crave.

Check the Thermostat Settings:

Start with the basics. Ensure that your thermostat is set to the desired temperature and mode (cooling). Sometimes, a simple adjustment can solve the problem.

Inspect the Air Filter:

A clogged or dirty air filter can restrict airflow, causing your AC to work inefficiently. Regularly check and replace air filters to maintain optimal performance.

Examine the Circuit Breaker:

A tripped circuit breaker can interrupt power to your air conditioner. Check the circuit breaker box and reset any tripped breakers related to the AC unit.

Inspect the Condenser Unit:

Head outside to check the condenser unit. Ensure there are no obstructions like debris or overgrown plants blocking the airflow. Clean the fins gently with a soft brush.

Assess the Refrigerant Levels:

Low refrigerant levels can affect cooling efficiency. If you notice ice on the evaporator coils or reduced cooling, it may be a sign of a refrigerant issue. Contact a professional technician to assess and recharge if necessary.

Test the Capacitors:

Faulty capacitors can cause your AC to stop working. Use a multimeter to test the capacitors, and if they’re not functioning properly, consider contacting a professional for replacement.

Examine the Evaporator Coils:

Inspect the evaporator coils for dirt and debris. If they are dirty, it can impede heat absorption, affecting the cooling process. Clean the coils carefully or seek professional help.

Inspect the Ductwork:

Leaks or blockages in the ductwork can compromise airflow. Check for visible issues and consider contacting a professional duct cleaning service to address hidden problems.

Ensure Proper Insulation:

Insufficient insulation can result in cooled air escaping, reducing the effectiveness of your AC. Check and improve insulation in key areas, such as windows and doors.

Call a Professional Technician:

If you’ve tried the above steps and your air conditioner is still not working, it’s time to call in the professionals. A trained technician can diagnose and fix complex issues, ensuring your AC operates efficiently.


Facing a malfunctioning air conditioner can be a source of frustration, especially during the hot summer months. By following these troubleshooting steps, you can address common issues and potentially restore your AC to proper working order. Remember, for more complex problems or if you’re not comfortable performing these checks, seeking the assistance of a professional technician is the best course of action to ensure your comfort is restored promptly.
