10 signs that your A/C may have been affected by a storm

It is important to know the signs of a damaged air conditioning unit to ensure you and your family safe. Keep in mind that the troubleshooting steps below are intended for minor issues, and it’s crucial to consult a qualified HVAC professional for proper diagnosis and repair of storm-damaged air conditioning systems.

Loss of power

If your air conditioning system suddenly stops working after a storm, it could indicate electrical damage caused by power surges or lightning strikes.

How to troubleshoot:

  • Check if the circuit breaker for your AC unit has tripped. If so, reset it.
  • Ensure that the power switch or disconnect switch near the outdoor unit is in the “on” position.
  • Make sure there are no power disruptions in your neighborhood as a result of the storm.

Reduced airflow

Inspect your vents for decreased airflow. Debris or damage to the outdoor unit from the storm may restrict the proper circulation of air.

How to troubleshoot:

  • Inspect and clean your air conditioners air filters. Clogged filters can restrict airflow, and it may be best to replace them if necessary.
  • Clear any debris or obstructions around the outdoor unit that may be blocking airflow.

Strange noises

Unusual rattling, grinding, or banging noises from your unit could indicate loose or damaged components caused by the storm.

How to troubleshoot:

  • Turn off the A/C and inspect the unit for any visible damage or loose parts. Tighten loose screws or bolts if safe to do so.
  • If the noise persists, it’s best to call Chas Roberts to have one of our technicians come out to diagnose and repair the issue.


Storm damage may result in water infiltration, leading to leaks or excessive moisture around the A/C unit or in the indoor area.

How to troubleshoot:

  • Check the drain pan and drain line for clogs or blockages. Clear any debris or buildup.
  • If you notice refrigerant leaks, do not attempt to fix them yourself. Refrigerants used in cooling systems can be hazardous to your health and the environment if mishandled. They may contribute to ozone depletion or greenhouse gas emissions, and improper handling can lead to personal injury, environmental damage, and legal consequences. Secondly, repairing refrigerant leaks requires specialized knowledge and equipment possessed by HVAC professionals who are trained to handle these substances safely. They understand the complexities of cooling systems and can address underlying issues that may cause leaks, preventing further damage.

Tripped circuit breakers

If the circuit breaker related to your air conditioning system keeps tripping after a storm, it suggests an electrical issue that needs attention.

How to troubleshoot:

  • Locate the breaker panel in your home and visually inspect it. Look for the breaker that has shifted to the “off” position or is in a position between “off” and “on.”
  • To reset the breaker, firmly switch it to the “off” position and then back to the “on” position. You should feel a definite click when it engages. If it doesn’t stay in the “on” position and immediately trips again, there may be a more significant issue.

Ice formation

Storm damage can disrupt the refrigerant cycle, causing the evaporator coil to freeze. Ice formation on the coil is a clear indication of a problem.

How to troubleshoot:

  • Turn off the air system to allow the ice to melt.
  • Check the air filters for dirt or blockage. Clean or replace them if necessary.

Unresponsive thermostat

If the thermostat is unresponsive or not functioning correctly after a storm, it could be due to damage to the wiring or control system.

How to troubleshoot:

  • Ensure your thermostat has power and is set to the appropriate settings.
  • Check for any loose or damaged wiring connections.

Burning smell

A strong burning smell emanating from your air conditioning system post-storm indicates electrical damage and requires immediate professional assistance.

How to troubleshoot:

  • Turn off the system immediately and disconnect the power.
  • Do not attempt any repairs yourself as it could be very dangerous.

Debris damage

Inspect the outdoor unit for debris accumulation, bent fins, or physical damage caused by flying objects or fallen tree branches during the storm.

How to troubleshoot:

  • Remove any debris or obstructions around the outdoor unit.
  • Gently straighten bent fins using a fin comb or seek professional assistance for more severe damage.

Inconsistent cooling

If your air conditioning system is struggling to maintain a consistent temperature or the cooling is inadequate, storm damage could be the culprit that’s affecting the system’s performance.

How to troubleshoot:

  • Check the thermostat settings to ensure they are properly configured.
  • Clean or replace dirty air filters.
  • If the issue persists, contact a Chas Roberts professional technician to assess and repair the system.
