Tricks nobody tells you!.
A few days ago I came across a thread on a home repair forum that caught my attention. A user was sharing his method for cleaning his split air conditioner without calling technicians or spending money. The interesting thing is that he wasn’t an expert, just someone tired of breathing dusty air every summer.
Here’s the most useful thing I learned from that post and other comments.
How to clean a split air conditioner without complications
The guy explained that he started noticing his unit was cooling less and making a strange noise. He looked up tutorials and decided to do it himself. His first discovery: you don’t need expensive products.
With just warm water, mild soap and a soft-bristled brush, he cleaned the filters. The trick is to let them air dry before putting them back. Many commented that this alone improves performance by 50%.
But what really made the difference was cleaning the evaporator fins with an old toothbrush. However, he warned: you have to do it carefully so as not to bend the fins.

In that same thread, another person shared their experience with window units. It turns out the process is similar but with one crucial extra step: always unplug the unit before starting.
The dirtiest part is usually at the back. He used a vacuum cleaner to remove the thick dust and then a mixture of white vinegar and water to disinfect. Something curious he mentioned: the air distribution louvers tend to accumulate invisible mold.
For these, he recommended a cloth dampened with isopropyl alcohol. Several users confirmed that this eliminates that “stuffy” smell that sometimes comes out when you turn on the air.
The mistakes almost everyone makes (and how to avoid them)
Several common mistakes kept coming up in the comments. The most serious one: using pressurized water on split units. It seems logical for removing dust, but it can damage the internal electronic components.
Another frequent mistake is forgetting to clean the drain. A user told how his air conditioner started dripping inside the house because of this oversight. The solution was simple: run a flexible wire through the drain pipe to remove obstructions.
There was also debate about frequency. Some said every 3 months, others before each hot season. The general conclusion: better safe than sorry.
Is it worth doing it yourself or calling a technician?
The discussion got interesting here. Several professional technicians chimed in to clarify that a deep annual cleaning does require experts, but basic maintenance anyone can do.
The original user calculated that in 5 years he had saved about $600 on cleaning services. His final advice: “If you’re afraid, start with just the filters. You’ll see the difference and lose the fear.”
And you? Would you dare to try it or would you rather leave the job to the professionals? 🛠️❄️
P.S.: All of this comes from real experiences of normal people, not technical manuals. Sometimes the best solutions come from trying simple things.
