How to Keep Your AC Running Strong During Heat and Humidity

Summer heatwaves can be brutal, especially when combined with high humidity levels. In such sweltering conditions, the last thing you want is for your air conditioning (AC) unit to falter. To ensure your AC keeps running strong and effectively cools your space, it is vital to follow a few essential maintenance tips. By taking proactive measures, you can avoid potential breakdowns, extend the lifespan of your AC, and maintain a comfortable indoor environment. Let’s explore some key strategies to keep your AC operating efficiently even during the harshest heat and humidity.

1. Regularly Clean and Replace Air Filters

Air filters play a crucial role in maintaining clean and fresh air indoors. Over time, these filters can become clogged with dirt, dust, and pollen, hindering the airflow and putting added strain on your AC system. To prevent this, it is necessary to regularly clean or replace your air filters.

Clean your filters once a month or according to the manufacturer’s recommendations. If you have washable filters, rinse them thoroughly with water and allow them to dry completely before re-inserting. For disposable filters, replace them with new ones after cleaning your unit, ensuring a constant flow of clean air throughout your space.

2. Clear the Area Around the Outdoor Unit

The outdoor unit of your AC system needs proper airflow to function efficiently. Make sure to remove any debris, leaves, or overgrown vegetation around the unit. Keep a distance of at least two feet between the outdoor unit and any obstructions such as bushes, tall grass, or trees. This will prevent restricted airflow and allow the unit to cool the air effectively.

3. Check and Clean Condenser Coils

The condenser coils of your AC system are responsible for releasing heat from your home into the surroundings. Over time, these coils can accumulate dirt, dust, and debris, reducing their efficiency. Regularly inspect the coils for any signs of dirt buildup and clean them if necessary.

To clean the coils, turn off the power to the outdoor unit and use a soft brush or a vacuum cleaner with a brush attachment. Gently remove the dirt and debris, taking care not to damage the delicate fins of the coils. Regular cleaning of the condenser coils will enhance the cooling capacity of your AC system, allowing it to combat heat and humidity effectively.

4. Keep the Drainage System Clear

As your AC unit operates, it produces condensate, which needs to be drained away efficiently. Any blockages in the drainage system can result in water backing up and potential damage to your AC system. Ensure that the drainage pipes are clear and not clogged with dirt or debris.

If you notice water pooling around the indoor unit or suspect a clogged drain, use a wet-dry vacuum or a pipe cleaner to remove any blockages. Maintaining a clear and unrestricted drainage system will prevent water damage and ensure your AC system runs smoothly even in humid conditions.

5. Schedule Professional Maintenance

While regular maintenance by the homeowner is essential, it is equally important to have your AC system professionally serviced at least once a year. Scheduling annual maintenance visits from a qualified technician can help identify and resolve any underlying issues before they escalate.

During a professional maintenance visit, the technician will inspect and clean various components of your AC system, check refrigerant levels, verify electrical connections, and ensure optimal performance. They can also provide recommendations for any necessary repairs or upgrades to keep your AC running strong all summer long.

6. Optimize Your Thermostat Settings

Your thermostat plays a pivotal role in maintaining a comfortable indoor temperature. Setting your thermostat to a reasonable and energy-efficient temperature can help your AC system work more effectively while still keeping you cool.

During hot and humid days, it is advisable to set your thermostat at a slightly higher temperature than you normally would. Aim for a temperature that still provides comfort but doesn’t strain your AC system excessively. Consider using a programmable or smart thermostat to optimize your cooling schedule based on your daily routine.


With the scorching heat and high humidity, it is crucial to keep your AC running at its best during the summer months. Regularly cleaning and replacing air filters, clearing the area around the outdoor unit, cleaning condenser coils, maintaining a clear drainage system, scheduling professional maintenance, and optimizing thermostat settings are key steps towards ensuring your AC performs at its peak efficiency. By following these maintenance tips, you can enjoy a cool and comfortable indoor environment even in the most extreme weather conditions.
