When your air conditioning (AC) system isn’t performing at its best, it can be tempting to call in a professional right away. However, some minor issues can be easily resolved with a bit of troubleshooting. Addressing these problems yourself not only saves money but also ensures your system runs efficiently. Today, we at Ambient Heating & Air Conditioning would like to offer a quick guide on how to help you troubleshoot common AC issues before seeking professional help.

Verify Thermostat Settings

The thermostat controls your AC system, so it’s a good place to start. Ensure it’s set to “cool” mode and that the temperature setting is lower than the current room temperature. If your thermostat is programmable, check the settings to ensure they are correctly configured. Sometimes, simply replacing the thermostat batteries can resolve issues with unresponsive or incorrect readings.

Inspect Air Filter

A clogged or dirty air filter can significantly impact your AC’s performance. Locate the filter, usually found in the return air duct or the blower compartment. Remove it and inspect its condition. If it’s dirty or covered in dust, replace it with a new one. Regularly changing the air filter every 1-3 months can prevent many common AC issues and improve air quality.

Examine Circuit Breaker

If your AC is not turning on at all, check the circuit breaker. Sometimes, a tripped breaker can cut off power to the system. Locate your home’s electrical panel and look for a breaker that’s in the “off” position. Reset it by flipping it back to the “on” position. If the breaker trips again, it may indicate an underlying electrical issue that needs professional attention.

Clean Condenser Coils

The condenser coils, located in the outdoor unit, can accumulate dirt and debris over time, which impairs the system’s efficiency. Ensure the unit is off before cleaning. Remove any visible debris around the unit and use a garden hose to gently wash the coils. Be careful not to use high pressure, as this can damage the coils. Once clean, let the unit dry completely before turning it back on.

Check for Airflow Blockages

Poor airflow can be a result of blockages in the ductwork or around the AC unit. Ensure that vents and registers are open and unobstructed. Furniture, drapes, or other objects should not block the airflow. Additionally, inspect the ductwork for any visible signs of damage or disconnection. Proper airflow is crucial for the efficient operation of your AC system.

Inspect AC Drain Line

The AC unit’s drain line can become clogged with algae or debris, leading to water damage and system malfunctions. Locate the drain line, which is typically a PVC pipe near the indoor unit. Check for visible clogs or leaks. You can try clearing the line with a small plumber’s snake or a mixture of vinegar and water. If you’re unsure or uncomfortable with this task, it’s best to consult a professional.

Listen for Unusual AC Noises

Unusual noises, such as banging, rattling, or squealing, can indicate minor issues like loose components or a failing fan. While some noises might be manageable, persistent or severe noises could signal a more significant problem. If you’re not confident in identifying or fixing the issue, it’s wise to call a professional to avoid potential damage.

Verify AC System Settings

Ensure that all settings on your AC system, including fan speed and cooling modes, are correctly adjusted. Sometimes, issues arise from simple misconfigurations rather than mechanical failures.
