Inspection of cooling fins

The cooling fins, located on the outdoor unit, play a vital role in heat dissipation. Over time, these fins can become bent or dirty, hindering airflow and reducing the unit’s efficiency. Inspecting the cooling fins before summer allows you to identify any bent fins and straighten them using a fin comb. Additionally, cleaning the cooling fins with a soft brush or vacuum can remove any accumulated dirt, ensuring maximum heat transfer.

Testing the system’s performance

Before the summer season arrives, it is essential to test the performance of your A/C system. Turn on the unit and observe its cooling capability. Check if the air flow is consistent and the temperature reaches the desired level. If you notice any issues, such as weak airflow or inadequate cooling, it may be necessary to call a professional to diagnose and address the problem before the summer heat sets in.

Over-Summer A/C Maintenance

Continual air filter checks

During the summer season, air filters can become clogged more quickly due to increased usage and higher pollen levels. Continually checking and replacing air filters throughout the summer is crucial to ensure optimal airflow and cooling efficiency. Neglecting to change dirty filters can strain the A/C system, leading to decreased performance and potential issues.

Maintaining a clear outdoor unit

As the summer progresses, it is important to regularly maintain a clear outdoor unit. Periodically check for any debris that may have accumulated around the unit and clear it away. Falling leaves, grass clippings, and other outdoor debris can block airflow, reducing the effectiveness of your A/C system. Ensuring a clean and unobstructed outdoor unit allows the system to operate efficiently.

Inspecting for refrigerant leaks

Refrigerant leaks can significantly impact the performance of your A/C unit and lead to decreased cooling capability. Throughout the summer, it is essential to inspect your unit for any signs of refrigerant leaks, such as ice buildup or decreased cooling efficiency. If you suspect a refrigerant leak, it is important to contact a professional to identify and repair the issue promptly.

A/C Maintenance: Your Essential Seasonal Checklist

Verifying thermostat accuracy

The accuracy of your thermostat is crucial for maintaining a comfortable indoor climate and optimizing energy efficiency. Over time, thermostats may become less accurate, leading to temperature discrepancies and potentially excessive energy consumption. During the summer, it is recommended to periodically verify the accuracy of your thermostat by comparing the displayed temperature with an external thermometer. If there are significant differences, it may be necessary to calibrate or replace the thermostat.

Pre-Fall A/C Maintenance

Cleaning the evaporator coil

As the summer season comes to an end, it is important to clean the evaporator coil of your A/C unit. The evaporator coil can accumulate dirt and debris over time, hindering its heat absorption capabilities. Using a soft brush or vacuum, gently remove any accumulated dirt from the coil’s fins. Cleaning the evaporator coil ensures the efficient transfer of heat, allowing your A/C system to operate optimally.

Checking for any necessary repairs

Before the cooler weather arrives, it is crucial to inspect your A/C unit for any necessary repairs. Look out for worn-out components, loose connections, or signs of corrosion. Addressing any needed repairs promptly can prevent issues from worsening and ensure that your A/C system operates reliably when needed.

Looking out for any unusual noises or smells

Unusual noises or odors coming from your A/C system can indicate underlying issues that require attention. As the summer season ends, listen for any unfamiliar sounds, such as grinding, rattling, or screeching. Additionally, pay attention to any unusual odors, such as a burning smell or musty odor. If you detect any of these signs, it is important to have a professional inspect your A/C system and determine the cause.
