Step 1: Dry the AC

Before cleaning your AC, it’s important to dry it thoroughly to remove any moisture inside. Running the AC in fan mode for 30-40 minutes can help evaporate any accumulated moisture.

Step 2: Remove and Clean the Air Filters

The air filters in your AC can accumulate dust and debris over time, reducing airflow and efficiency. Remove the front panel of the indoor unit to access the air filters. Clean the filters using water and a mild detergent if necessary. Allow the filters to dry completely before reinserting them into the AC unit.

Step 3: Clean the AC Fins

The cooling fins of your AC can also become blocked with dust and debris, hindering airflow. Use an air blower or compressor to blow out the dust from the fins. Be sure to move the blower vertically to avoid damaging the fins.

Step 4: Use an AC Cleaning Solution

Using an AC cleaning solution, such as Blueoxy, can help kill bacteria and remove any remaining dust or debris from the AC unit. Spray the solution on the metal fins and allow it to sit for five minutes before wiping it off.

Step 5: Reassemble and Test the AC

Once the filters and fins are clean, reassemble the AC unit and plug it back in. Set the AC to maximum cooling and run it for 15-30 minutes to ensure that it is functioning properly. If you encounter any issues you will want to contact your local AC service for additional assistance and information. They will be able to help you diagnose any potential issues.

Additional Tips for AC Maintenance

Something that you will want to do is regularly check and clean the outdoor unit of the AC to ensure proper airflow. If you don’t do this, there are clogs that can form and debris can get in the way of proper airflow. You will also want to replace the air filters at least every 3-6 months. The reason is that you want to make sure that you have proper airflow through the filters. If they are looking grey or feeling heavy, then it is probably time to change them out since the accumulation of dust has gotten to be too much.

Another major part of maintenance is making sure that the AC unit is free of any debris around it. From trash to grass, you want to make sure that the unit is cleared around the vents for proper ventilation. If there is any airflow obstruction, this will cause your AC to run inefficiently and make it difficult to maintain energy savings as well as the temperature of your home.

Finally, there are technological advancements that you can use with your AC unit to make better use of energy-saving features as well as prevent the overuse of the unit. One thing that you can do is invest in a programmable thermostat that will alternate temperatures by the time of day. There are also units that are capable of altering the temperature in individual rooms. Those are also a great investment!


Performing DIY AC services at home can help improve the efficiency and performance of your air conditioner. By following the steps outlined in this article, you can keep your AC running smoothly and extend its lifespan. However, it’s important to note that while these DIY tasks are beneficial, professional AC services are still recommended periodically to ensure the long-term health of your air conditioner.

In conclusion, performing regular DIY AC services is a cost-effective way to maintain the efficiency and longevity of your air conditioner. By following the simple steps outlined in this article, you can keep your AC running smoothly and avoid costly repairs. However, it’s important to remember that while DIY maintenance is beneficial, it should not replace professional AC services. A professional HVAC technician can inspect your AC system thoroughly, identify any potential issues, and perform maintenance tasks that require specialized tools and expertise. By combining DIY maintenance with professional servicing, you can ensure that your AC remains in optimal condition, providing you with cool and comfortable air for years to come.
