When your air conditioner stops cooling or starts acting up, it’s tempting to immediately call for professional repair. However, many common AC issues can be solved at home with a little troubleshooting. By checking a few basic things before making the call, you can save both time and money.
1. Check the Power Supply
Sometimes, the issue is as simple as a tripped breaker or a loose plug. Make sure your AC unit is properly connected to a power source, and check the breaker box for any tripped switches.
2. Inspect the Thermostat Settings
If your thermostat is not set correctly, your AC won’t function as expected. Ensure it’s set to “cool” mode, and the temperature is lower than the current room temperature.
3. Clean or Replace the Air Filter
A dirty air filter can block airflow, making your AC less efficient. Cleaning or replacing the filter regularly improves cooling performance and extends the system’s life.
4. Examine the Outdoor Unit
Leaves, dirt, and other debris can clog the outdoor condenser unit, reducing efficiency. Clear away obstructions and gently clean the fins with a soft brush.
5. Look for Drainage Issues
Blocked condensate drains can cause water leakage. Check the drainage pipe for clogs and remove any blockages to prevent overflow.
6. Perform a Quick Warranty Check
Before calling for repairs, confirm if your AC is still covered under warranty. You can quickly perform a warranty check to see if repair costs might be covered, saving you money.
When to Call a Professional
If your AC still doesn’t work after these steps, it’s time to call a technician. Issues with refrigerant, electrical components, or internal parts require professional expertise.
