In this guide, I’m going to show you how to clean your AC unit inside, step by step. I’ve got plenty of tips and tricks to make the whole process smoother and more effective.
Why Cleaning Your AC Unit Inside is Important
Before we jump into the how-to, let’s talk about why it’s so important to keep your AC unit inside clean.
Over time, dust, dirt, and all sorts of debris can build up on the coils, filters, and other parts of your AC.
This buildup doesn’t just sit there it actually restricts airflow, makes your AC work harder, and can lead to higher energy bills and even damage the unit.
So, let’s start the process/steps of cleaning your AC unit inside.
Tools and Materials Needed
Before you start cleaning your AC unit inside, gather the following tools and materials:
- Screwdriver
- Soft brush or cloth
- Vacuum cleaner with a soft brush attachment
- Fin comb (optional)
- Mild detergent or coil cleaner
- Spray bottle
- Gloves and safety goggles
Step 1: Turn Off the Power
Safety first! Before you do anything else, turn off the power to your AC unit at the circuit breaker or unplug it. Trust me, you don’t want to mess around with electricity while cleaning.
Step 2: Remove the Outer Cover
Grab your screwdriver and carefully take off the outer cover or grille of your indoor AC unit. Keep those screws in a safe place you’ll need them later. Once the cover is off, you’ll see the coils and other parts that need cleaning.
Step 3: Clean or Replace the Air Filter
The air filter is one of the most important parts to clean. If it’s reusable, give it a gentle wash with some mild detergent and water.
Make sure it’s completely dry before you put it back. If your filter is the disposable kind, just swap it out for a new one. A clean filter means better airflow and a more efficient AC.
Step 4: Clean the Evaporator Coils
Next up, the evaporator coils. These guys can get pretty grimy, so use a soft brush or cloth to gently wipe away the dirt.
If there’s some stubborn grime, spray on a little coil cleaner or a mix of water and detergent, let it sit for a few minutes, then wipe it clean. This step is key to keeping your AC cooling efficiently.
Step 5: Vacuum the Interior
After you’ve cleaned the coils, grab your vacuum cleaner with the soft brush attachment and suck up any remaining dust and debris from the inside of the unit.
Pay extra attention to the blower fan and other parts that tend to collect dirt. This will help prevent clogs and keep your AC running smoothly.
Step 6: Straighten Bent Fins (Optional)
If you notice any bent fins on the evaporator coils, you can use a fin comb to straighten them out. This isn’t a must-do, but it can help improve airflow and make sure your AC is working at its best.
Step 7: Reassemble the Unit
Once everything’s clean, put the cover or grille back on and secure it with the screws you saved earlier. Double-check that everything’s in place before you turn the power back on.
Step 8: Test the Unit
Now that your AC is clean and back together, turn the power on and give it a test run. Make sure it’s running smoothly and cooling properly.
If you hear any strange noises or it’s not cooling like it should, you might need to look into some additional maintenance.
