Common AC Problems and How to Troubleshoot Them
-
Clogged Filters
One of the most common causes of poor cooling performance is a clogged air filter. Over time, dirt and debris accumulate in the filter, restricting airflow. This not only reduces efficiency but can also lead to overheating or freezing of the system.
Steps to Troubleshoot:
– Inspect the filter: Turn off your AC and remove the filter. Hold it up to the light; if you can’t see through it, it’s clogged.
– Clean or replace the filter: Wash reusable filters with water and mild soap, then let them dry completely before reinserting. For disposable filters, replace them with a new one.
– Schedule routine maintenance: Regularly checking and replacing filters (every 1-3 months) can prevent future issues.
-
Refrigerant Leaks
A refrigerant leak is another common problem that can cause your AC to blow warm air or stop cooling altogether. Unlike clogged filters, this issue isn’t always visible, but there are signs to watch for.
Signs of a Refrigerant Leak:
– Hissing or bubbling noises near the unit.
– Ice forming on the evaporator coils.
– Reduced cooling performance, even at lower thermostat settings.
Steps to Troubleshoot:
– Check for ice: If you notice ice on the coils, turn off your AC immediately to prevent further damage.
– Monitor performance: If your AC struggles to cool, it might indicate a refrigerant issue.
– Call a professional: While identifying a leak is possible, fixing it requires professional equipment. Smoky Best AC is always here to help if this issue arises.
-
Thermostat Issues
An improperly working thermostat can result in inconsistent temperatures or no cooling at all. Fortunately, thermostat issues are usually straightforward to resolve.
Steps to Troubleshoot:
– Check the power: Ensure your thermostat has working batteries or is receiving power.
– Verify settings: Set the thermostat to “cool” mode and lower the temperature to see if the system responds.
– Calibrate if needed: An older thermostat might need recalibration for accurate temperature readings.
– Upgrade to a programmable thermostat: If troubleshooting doesn’t help, consider upgrading for better efficiency and control.
