Check the thermostat: Please ensure that the thermostat is set to the “cool” setting and that the temperature is adjusted at least 5 degrees lower than the current room temperature. Additionally, make sure the thermostat has a power source and fresh batteries if it operates on battery power.

Check the power supply: See if the air conditioner is receiving power. If it’s not turning on, inspect the circuit breaker or fuse box to determine if a circuit has tripped or a fuse has blown.

Inspect the air filters: Dirty or obstructed air filters can hinder airflow and lead to inefficient operation or system shutdown. It is important to regularly inspect and replace air filters when they become dirty. Add a reminder to your calendar to check your filter once a month, more frequently is you have pets.

Clean up around the outdoor unit: Make sure your central A/C’s outdoor unit is clear of any debris such as leaves, grass, litter, or branches. Blocked airflow can have a negative impact on the performance of the system.

Listen for unusual sounds: If you notice unusual sounds emanating from the central air conditioner, it could be a sign of a mechanical problem. Professional assistance may be necessary if you hear grinding, banging, rattling, or squealing noises.

Look to see if there is ice buildup: If you notice ice forming on either the indoor or outdoor unit, it’s important to promptly turn off the system and allow it to thaw. The accumulation of ice can arise from issues with airflow or refrigerant.

Check the condensate drain line: A blocked condensate drain line can result in water leakage, potentially causing safety mechanisms to shut down the system. If you encounter a clog, make sure to clean the drain line promptly.

Inspect the ductwork: Look over the ductwork for any discernible harm or disconnected sections that may be responsible for air leakage.

Check for refrigerant leaks: Low refrigerant levels can impede the cooling efficiency of your system. If you suspect a refrigerant leak, it is crucial to contact Williams Energy right away for a service call.

Reset the system: Sometimes, a system reset can help resolve minor issues. Turn off the power to the air conditioner, wait a few minutes, and then turn it back on.
