Regular maintenance is the key to extending the lifespan of your AC while ensuring optimal performance. To help you beat the heat, we’ve gathered some AC maintenance tips straight from the pros. Read on to stay cool this summer!

1. Clean or Replace Filters:

Dirty filters hinder airflow, reducing the effectiveness of your AC. Regularly clean or replace your filters to keep your air conditioner running smoothly. Clogged filters not only lead to increased energy consumption but also have a negative impact on the air quality in your home.

2. Check the Thermostat:

A faulty thermostat can result in an unreliable cooling experience. Make sure your thermostat is accurate and functioning correctly. Consider upgrading to a programmable thermostat that allows you to adjust temperature settings to save energy and money when you’re not at home.

3. Inspect the Condenser Unit:

The outdoor condenser unit of your AC is susceptible to dust, debris, and vegetation buildup. Regularly inspect the unit and remove any leaves, dirt, or obstructions around it. Ensure that there is enough clearance for proper airflow, as restricted airflow can lead to poor cooling performance.

4. Clean the Condenser Fins:

The condenser fins, located on the exterior of the unit, are responsible for releasing heat from the system. Over time, these fins can accumulate dirt and grime, reducing their efficiency. Gently brush away any visible dirt or debris using a soft brush or vacuum cleaner. Be cautious not to damage the delicate fins.

5. Rinse the Evaporator Coil:

The evaporator coil, located inside your AC unit, can become dirty and affect its performance. To clean the coil, turn off the power supply and remove the access panel. Use a soft brush to remove dirt and debris, then gently rinse the coil with a mixture of warm water and mild detergent. Be sure to let it dry completely before replacing the access panel.

6. Clean or Replace the Drainage Line:

The drainage line removes the condensation created by your AC. Over time, it can become clogged with mold, algae, or debris. Ensure proper drainage by pouring a mixture of bleach and water down the line to remove clogs and prevent odors. If the line is damaged or severely clogged, it may need professional attention.

7. Inspect the Air Ducts:

Leaky air ducts can lead to energy wastage and uneven cooling throughout your home. Inspect your air ducts for any cracks or gaps and seal them with duct tape or proper sealing materials. Additionally, consider having your air ducts professionally cleaned to improve indoor air quality and ensure efficient airflow.

8. Schedule Professional Maintenance:

While regular DIY maintenance is crucial, it’s wise to schedule professional AC maintenance at least once a year. HVAC professionals have the expertise to thoroughly clean and inspect your system, identify any potential issues, and optimize its performance. Regular maintenance can help prevent costly breakdowns and increase the overall lifespan of your AC.


Maintaining your air conditioning unit is essential to beat the summer heat. By following these tips from the pros, you can ensure your AC performs at its best while keeping your energy bills in check. Remember to clean or replace filters regularly, inspect and clean the condenser unit and fins, rinse the evaporator coil, clean or replace the drainage line, inspect and seal air ducts, and schedule professional maintenance. Stay cool and enjoy the summer!
