We all know that air conditioning units can get dirty, especially without regular air conditioning repair and maintenance. Dirt, dust, pet hair, and other particles will accumulate over time, which in turn reduces the efficiency of your AC.

But what most people don’t realize is that you can clean this dirt and debris without voiding your warranty!

In this article, we at Top Air Cond Services will share the secrets to cleaning your air conditioner without voiding its warranty – so read on if you’re interested in learning more about how to keep your AC running efficiently for years to come.

Unplug Your AC Unit 

Your first step is to unplug your AC unit. This will help keep you safe if the power goes out while cleaning because the system won’t start up before it’s been inspected for safety.

To unplug your AC unit, you need to find the circuit breaker and turn off the power to your unit.

This is usually located in a box outside of your house or garage, but can also be indoors near where you plugged the AC into an outlet.

Find it by looking for exposed wires that are connected to what looks like a big metal cube (this should be marked “circuit breaker”)

Once done, remove the outer covers of your unit and use a vacuum cleaner to remove any dust found on the surface.

Take out AC Unit Filters 

The next step is to take out the AC unit filters. These will need to be cleaned or replaced periodically, so this is a good time to make sure they are clean and in place.

If it’s not too dirty you can just use your vacuum cleaner again with an attachment for dusting furniture; if that doesn’t work you may want to purchase a replacement filter at an appliance store as these are usually very inexpensive (just don’t forget to take out the old one!).

You should also check for any visible damage on the fins of your AC unit – if there’s anything wrong with them, then replace them ASAP because it could affect airflow and efficiency!

Remove and Clean AC Directional Fins 

When you take out the filters, inspect your AC directional fins.

If they have any dirt or dust on them that won’t come off with a vacuum cleaner then use water and soap to remove it from these surfaces – this will help keep particles from spreading throughout the system.

Remember, when cleaning your directional fins, you should be aiming the hose at an angle so that water and soap will run over all of them.

After this, you should dry these fins with a rag or towel, then re-install them into place on your AC unit’s body.

Be Sure to Clean the AC’s Rotary Fan Blades 

Next, use your vacuum cleaner to clean the rotary fan blades on top of your AC unit.

This is important because these are an essential component for air circulation and any dust or dirt that gets stuck in them can affect efficiency.

You’ll also want to check the surface area around this blade as there could be a build-up of debris nearby – just make sure you don’t get too close with your vacuum or else you might inhale those allergens!

Brush The AC Unit’s Cooling Fins 

When cleaning your cooling fins, you need to use a brush to remove any dirt or dust from the surface.

Remember that these have fins in them and they should be thoroughly brushed with water so that it will rinse off of those surfaces effectively.

You’ll want to use long strokes on each one, then rub your fingers over the top (without touching) – this will help you feel for areas where there’s still some left behind.

If something is getting stuck during this process, just continue brushing until all debris is gone!

Finally, when you’re done cleaning, make sure everything has been put back into place and plugged in before turning on the power again!


The importance of understanding how to clean your AC unit without voiding the warranty is huge.

There are many people who don’t know about this and it could be a costly mistake!

This post has offered some great tips, such as using a damp cloth or vacuum cleaner attachment on an air filter that isn’t too dirty.

Remember, if you’re not sure what will happen with your warranty after you have cleaned the unit yourself then call in for advice before proceeding.
