Cleaning your AC window unit coils is a simple yet crucial task to improve indoor air quality. Dirty coils can circulate pollutants and allergens back into your home.
Air conditioning coils can become clogged with dirt, dust, and debris over time, reducing their efficiency and effectiveness. In fact, dirty coils can increase energy bills by up to 37% and decrease air quality by 20%.
Regular coil cleaning can help maintain a healthy indoor environment and reduce energy consumption.

Understanding AC Window Units
Window AC units are a common sight in homes, but do you know how they work? They have two sets of coils and fins: the condenser coils in the back and the evaporator coils in the front.
These coils and fins are crucial for the unit's functionality, but they can get dirty and clogged over time. You can clean the front evaporator coils by removing the filter and front grill, and using compressed air to blow away dust and debris.

Cleaning the coils and fins requires some effort, but it's a great way to extend the life of your AC unit. To do this, you'll need to remove the case, which usually involves taking out screws around the edges, and then use a vacuum or compressed air to remove surface debris.

Window Unit Setup
Before you start using your window unit, make sure to clean the coils in the refrigerated air window unit. This is especially important before summer use, as it can help improve the unit's efficiency and prevent breakdowns.
You can clean the coils by removing the plastic filter on the inside of the house and washing it. Behind the filter are the radiator coils, which are dirty and need to be cleaned. You can use compressed air to blow dust and debris from the fins, or a soft bristle brush or fin comb to gently remove debris.
It's a good idea to clear out the drain line before cleaning the coils. This will ensure that water and cleaner can drain properly as you clean. To do this, look for a hole in the drain pan at the bottom of the unit, and make sure it's not blocked or plugged.
Before you start cleaning, turn off and unplug your window unit. If you can't unplug it, turn off the circuit breaker to the unit. This will prevent any accidents or electrical shocks.
Here are some steps to follow when cleaning your window unit:
- Remove large debris from inside the unit with your hands
- Look for signs of oil leaks on the compressor housing or beneath it
- Spray the coils down with water from a garden hose to remove loose dirt
- Use a spray cleaner or 3% hydrogen peroxide to deep clean the coils and fins
Remember to be gentle when cleaning the fins, as they can bend easily. You can use a fin comb or soft bristle brush to lightly remove debris, or a vacuum or compressed air to remove surface debris.
How to Use an AC Unit
Using an AC unit effectively is crucial for a comfortable and energy-efficient cooling experience. To start, it's essential to perform a deep clean of your window AC unit if you discover mold, paying special attention to the fan blade and drip pan.
Mold is a common issue in AC units, and Drago recommends using 3% hydrogen peroxide to scrub the interior, which should kill most things. This is a simple yet effective way to prevent mold from growing back.
Cleaning the condenser coil is also important, and if your AC is installed on the first floor, you can access it from the outside. You can use the dry method or clean with water using a spray bottle or hose with a nozzle attachment.
Make sure to turn off the power to the AC and ensure the water will drain outside if you choose to use this method. If your AC is angled correctly, the water should drain outside, which is a great way to keep your unit running smoothly.

Maintenance and Cleaning
To keep your air conditioner running efficiently, it's essential to clean the coils regularly. The Department of Energy recommends cleaning your window air conditioner thoroughly at least once a year, preferably before its first use of the season.
Before you start cleaning, unplug the unit from the receptacle to avoid electrical shock. Open windows or work outside to ensure adequate ventilation while using cleaners. Wearing personal protective equipment, including eyewear and gloves, can also protect you from sharp fins and protruding screws.
The best time to clean is right before you install it for the season or right after you remove it since you can easily take the unit apart. You can use a foaming coil cleaner and let it soak for 5-10 minutes to loosen the grime. A fin comb can also help straighten bent coil fins.
Remember to clean the filter once a month and replace it every three months to maintain optimal performance.
Prepare for
Before you start cleaning your air conditioner, it's essential to prepare the area and yourself for a safe and effective cleaning process.
First, always unplug the air conditioner from the receptacle to avoid electrical shock. This simple step can prevent accidents and ensure your safety.

To maintain good ventilation, open windows or work outside while using cleaners. This will help prevent the buildup of fumes and ensure a healthy cleaning environment.
Wear personal protective equipment, including eyewear and gloves, to protect yourself from sharp fins and protruding screws. Trust me, you don't want to get poked or scratched while cleaning!
If you'll be cleaning more than the filter and grille, lift the unit out of the window to access all areas. This will give you a clear view of the coils and other components that need attention.
Here are some essential items to have on hand:
- Personal protective equipment (gloves, eyewear)
- Cleaning supplies (water, spray cleaner)
- A garden hose (for outdoor units)
- A receptacle (to unplug the air conditioner)

The Department of Energy recommends cleaning your window air conditioner at least once a year. In addition to an annual cleaning, the filter should be cleaned once a month and replaced with a new one every three months.
Before cleaning, make sure to unplug the air conditioner and open windows or work outside to ensure adequate ventilation. Wear personal protective equipment, including eyewear and gloves, to protect from sharp fins and protruding screws.
To clean the coils in a refrigerated air window unit, apply a foaming coil cleaner and soak the coils in cleaner for 5-10 minutes. Use a fin comb to clean and unbend coil fins, and then rinse the cleaner off of outdoor units with a hose.
Here's a list of steps to clean a window AC unit:
1. Unplug the unit from the receptacle before cleaning.
2. Open windows or work outside to ensure adequate ventilation.
3. Wear personal protective equipment, including eyewear and gloves.
4. Use a foaming coil cleaner and soak the coils in cleaner for 5-10 minutes.
5. Use a fin comb to clean and unbend coil fins.
6. Rinse the cleaner off of outdoor units with a hose.
If you discover mold on your window AC unit, a deep clean is necessary. Use 3% hydrogen peroxide to scrub the interior, and make sure to clean the fan blade and drip pan, which are common places where mold forms.

Cleaning the Coil
Cleaning the coil is a crucial part of maintaining your air conditioner's efficiency and longevity. It's a task that can be done yearly, and it's recommended to do it before summer use.
You'll need to remove the case of your window air conditioner to access the coils and fins. This can be done by removing the screws around the edges of the case, usually found at the bottom. Once you've removed the necessary screws, you can pull the case straight up.
Using a vacuum or compressed air can help remove surface debris from the coils and fins. You can also use a fin comb or soft bristle brush to gently remove debris from the fins.
For a deeper clean, cover the electrical components with plastic and use a spray bottle with 3% hydrogen peroxide to spray down the fins and coils. Let the peroxide sit for about 10 minutes before lightly rinsing it with a water hose.

There are different types of coil cleaners available, including foaming coil cleaners and water-less coil cleaners. Foaming coil cleaners are best used on outdoor units, while water-less coil cleaners are better suited for indoor units.
Here's a step-by-step guide to using a foaming coil cleaner:
- Apply a foaming coil cleaner to the coils while they're still wet from a hose (for outdoor units) or use a water-less coil cleaner (for indoor units).
- Soak the coils in cleaner for 5-10 minutes, or the time specified on the cleaner's instructions.
- Use a fin comb to clean and unbend coil fins.
- Rinse the cleaner off the coils with a hose (for outdoor units).
- Reassemble the unit once you've thoroughly rinsed the cleaner from the coils.
Remember to be gentle when cleaning the coils and fins to avoid bending them. It's also essential to follow the instructions on your specific cleaner and take necessary safety precautions.
