5 Ways to Check Your AC System

Nov 13, 2020

Check the Filter

When your air conditioner doesn’t seem to be cooling your home as efficiently as it should, one of the initial steps you should take is to check your AC system’s filter. A filter filled with dust or debris can significantly hinder airflow, reducing your AC system’s cooling capacity. To do this, locate the air filter. This is typically found near the return air duct or inside the air handler unit. Once located, remove the filter and carefully inspect it for dust, dirt, and debris. A filter caked in grime requires immediate cleaning or replacement.

Clean the Condenser Fan Blades

Your AC system’s condenser fan blades, located in the outdoor unit, play a significant role in its overall operation. Over time, these blades can accumulate various types of debris, including dirt and leaves, which can negatively impact their ability to function properly. To clean the fan blades, first ensure the power to the outdoor unit is turned off. Next, gently remove the fan grille or housing to access the blades. Use a soft brush to sweep away any visible dirt or debris. If necessary, a soft cloth or mild detergent solution can also be used to clean the blades thoroughly. Remember, always wear safety glasses and gloves for your protection.

Inspect the Unit’s Exterior

Conducting regular inspections of your AC unit’s exterior can help you spot any potential problems before they develop into more serious issues. Look for signs of leaks, damage, or blockages around the unit. If you spot refrigerant leaks, hear unusual noises, or feel excessive vibrations, it’s crucial to contact a professional HVAC technician as soon as possible. Furthermore, weather conditions in your region can also impact your unit. For example, following heavy rain, check for standing water or excessive moisture inside the unit as it can lead to mold growth and affect your AC’s performance.

Replace the Thermostat

If your thermostat isn’t turning on or accurately regulating the temperature, it’s probably time to replace it. An improperly functioning thermostat can lead to uneven cooling or even a complete lack of cooling. When installing a new thermostat, it’s important to ensure it’s compatible with your specific AC system. Follow the manufacturer’s installation instructions carefully. Regular maintenance of the thermostat, including cleaning the vents around it every few months to prevent dust accumulation, is also crucial. A dirty filter can strain the system and affect the thermostat’s performance, so always remember to check your filter regularly. For more information, visit our AC Repair page.

Change the Refrigerant Charge

Unusual smells from your home or a lack of cooling efficiency from your AC system may signal a change in the refrigerant charge. The refrigerant plays a crucial role in heat absorption and release to provide cooling. Over time, refrigerant levels can diminish due to leaks or other problems. To resolve this issue, a qualified HVAC technician should inspect and recharge the refrigerant in your system. This process involves removing the old refrigerant, repairing any leaks, and adding the correct amount of new refrigerant to ensure optimal cooling performance.

By following these simple steps and regularly checking your AC system, you can ensure it operates efficiently, providing the cooling comfort you need. However, if you’re dealing with persistent issues or feel uncomfortable performing any of these maintenance tasks yourself, it’s always best to seek assistance from a licensed HVAC technician.
