Cleaning your portable AC coils is a crucial aspect of maintaining your cooling unit’s efficiency and longevity. This comprehensive guide will walk you through the process step by step, from disassembling the unit to cleaning the coils, and reassembling the unit. We’ll also cover common mistakes to avoid, how often you should clean your coils, and the benefits of regular cleaning.


To clean portable AC coils, first turn off and unplug the unit. Disassemble the unit to access the coils, then use a soft brush or vacuum to gently clean them. For stubborn dirt, use a commercial coil cleaner or a mild detergent and water mixture. Rinse the coils gently with water, dry them off with a towel or cloth, and then reassemble the unit.

Why Clean Your AC Coils?

The coils in your portable AC unit play a vital role in cooling your space. Over time, dust, dirt, and debris can accumulate on the coils, reducing their ability to absorb heat and cool the air effectively. This not only decreases the unit’s efficiency but also increases its energy consumption. To keep your AC unit running efficiently, it’s essential to clean the coils regularly.

Getting Started: What You’ll Need

To clean your AC coils, you’ll need some basic tools and materials. These include:

  • Screwdriver or drill
  • Vacuum with a soft brush attachment
  • Garden hose with a sprayer
  • Coil comb and fin comb
  • Gloves
  • Commercial cleaner or mild detergent
  • Cleaning brush or nylon scrub brush
  • A piece of cloth
  • Protective eyewear
  • Bucket or shallow pan
  • Spray bottle
  • Flashlight

Frequently Asked Questions

What is a commercial coil cleaner?

A commercial coil cleaner is a specialized cleaning solution designed specifically for cleaning the coils in air conditioning units. It can effectively remove grime, dirt, and dust that may accumulate on the coils.

Can I use a hairdryer to speed up the drying process of the coils?

No, it’s not recommended to use a hairdryer or any other heat source to speed up the drying process. Excessive heat can damage the coils. It’s best to let the coils air dry naturally.

How will I know if I’ve damaged the fins on the coils?

If the fins on your AC coils are bent or damaged, they’ll appear uneven or distorted. This can restrict airflow and reduce your AC unit’s efficiency. If you notice damaged fins, use a fin comb to straighten them out.

Can I clean the coils without disassembling the unit?

While it might be possible to clean the coils without fully disassembling the unit, it’s not recommended. Disassembling your AC unit allows for a more thorough cleaning, ensuring that all parts of the coils are clean and free of dust and debris.

Should I hire a professional to clean my AC coils?

While it’s possible to clean the coils on your own, hiring a professional can ensure the job is done correctly and safely, especially if you’re not comfortable disassembling and reassembling the unit.
