Keep Cool: Essential AC Maintenance Tips for Coastal North Carolina Summers

Anyone else feelin’ like…

Yeah, same. And unfortunately most AC units are too. Heat advisory after heat advisory has air conditioning units struggling to keep up. To ensure it performs at its best, regular maintenance is crucial. Below you’ll find a 10 easy ways to maintain your AC during the summer months in Coastal NC.


1. Change the Air Filter Regularly

One of the simplest yet most effective maintenance tasks is changing your air filter. During the summer, your AC runs more frequently, which means the air filter can get clogged faster. A dirty filter restricts airflow, making your system work harder and less efficiently. Aim to change the filter every 1-2 months to keep your AC running smoothly.

2. Clean the Coils

The evaporator and condenser coils of your AC unit can accumulate dirt and debris over time. This buildup reduces the coils' ability to absorb and dissipate heat, leading to decreased efficiency. Regularly inspect and clean the coils to ensure optimal performance. If you're unsure how to do this, consider hiring a professional to handle it.

3. Check the Refrigerant Levels

Proper refrigerant levels are essential for your AC's cooling efficiency. Low refrigerant levels can indicate a leak and lead to poor cooling performance. If you notice that your AC isn’t cooling as effectively, it might be time to call a technician to check and replenish the refrigerant levels.

4. Clear the Condensate Drain

The condensate drain allows moisture from the air to be removed from your home. Over time, this drain can become clogged with algae and mold, leading to water damage and increased humidity levels. Regularly check and clean the condensate drain to prevent blockages.

5. Inspect the Ductwork

Leaky or poorly insulated ductwork can lead to significant energy loss and reduced cooling efficiency. Inspect your ducts for any visible signs of damage and ensure they are properly sealed and insulated. Professional duct cleaning can also improve air quality and system efficiency.

6. Keep the Outdoor Unit Clean

The outdoor unit of your AC system can accumulate leaves, dirt, and debris, obstructing airflow and reducing efficiency. Keep the area around the unit clean and clear. Trim any overgrown vegetation and ensure there is at least two feet of clearance around the unit.

7. Adjust the Thermostat

Investing in a programmable thermostat can help you manage your cooling needs more efficiently. Set the thermostat to higher temperatures when you’re not home and lower it when you return. This reduces the workload on your AC and can lead to energy savings.

8. Schedule a Professional Tune-Up

While there are many maintenance tasks you can handle yourself, scheduling a professional tune-up is highly recommended. A licensed HVAC technician can perform a thorough inspection, identify potential issues, and optimize your system for peak performance.

9. Monitor Humidity Levels

Coastal North Carolina is known for its high humidity. Excess humidity can make your home feel warmer and strain your AC system. Use a dehumidifier to keep indoor humidity levels in check, enhancing your comfort and reducing the load on your AC.

10. Use Ceiling Fans

Ceiling fans are a great complement to your AC system. They help circulate cool air throughout your home, allowing you to set your thermostat a few degrees higher without sacrificing comfort. This can lead to energy savings and reduced wear and tear on your AC.


All of this to say, maintaining your air conditioning system during the summer months, especially in Coastal North Carolina, is essential for comfort, efficiency, and longevity. By following these maintenance tips, you can ensure your AC system performs optimally, keeping you cool and comfortable all season long.
