AC Chemical Wash: What to Expect During the Professional Service

AC chemical wash comes in handy when your air conditioner stops cooling like it used to.

Usually, when the AC’s inefficiency persists and is accompanied by other signs, such as a weird, musty smell, simple cleaning is not enough.

Importantly, chemical wash is not just a quick wiping out of dirt. During a chemical wash, professionals use chemicals that break down built-up grease, mold, and mineral gunk hiding deep inside your AC’s most important parts.

Therefore, in this post, we’ll explain what you should expect during a professional chemical wash and the reasons the procedure is necessary.

What Happens During a Real Chemical Wash?

​A chemical wash isn’t some quick job, but a careful, step-by-step process that only trained AC technicians should handle. Below is what you should expect during a chemical wash.

​1. Inspection and Preparation

First, the tech gives your system a thorough inspection to check refrigerant, airflow, coil condition, and the drain. If they spot tough buildup, they shut everything down and open up the units to access all the places grime likes to hide.​

2. Spraying the Unit’s Exposed Parts With Chemicals

This is the main and most important step. They spray high-quality, professionally recommended chemicals onto the coils, allowing them to seep into every crack and fin.

3. Wait For the Chemical to Work

They let the chemical sit to break down grease, dirt, mold, and minerals. Notably, the chemical solution is safe to use, and you shouldn’t worry about it corroding or damaging the metal components.

3. High-Pressure Rinse

Once the chemicals have loosened up the mess, it’s time for a high-pressure rinse. To rinse the loosened dirt, the technicians use just enough force to blast away the buildup without damaging the delicate fins.

Importantly, the technicians ensure they set up barriers to keep dirty runoff from reaching your floors or walls.

​4. Thoroughly Clean Everything Else

They don’t just stop with cleaning the coils. They thoroughly clean all other components, including the blower wheel, drain pan, and housing.

Importantly, they flush out all the dirt using the right chemical solutions to prevent mold from forming.​

5. Reassembly and Testing

Once everything’s sparkling clean, they put your AC back together and power it up. Then they conduct a full system test. During the test, they check refrigerant pressure to ensure the evaporator cools as it should, test the water drain, and double-check all safety controls.

Reasons Regular Cleaning Sometimes Doesn’t Do the Trick​, and You Need Chemical Wash

Usually, AC units accumulate more than just dust over time. The coils, both inside and outside, end up coated in a sticky mess as moisture and dust mix.

Notably, while you can swap filters and wipe things down, that stubborn layer stays put. Importantly, the consequences of this accumulated dirt are costly and difficult to ignore.

Some of the common consequences of foregoing chemical wash to remove stubborn dirt, and reasons chemical wash is necessary include:

• The air conditioner struggles to run: The accumulated layer of dirt acts like insulation, trapping heat and forcing your AC to work way harder than it should.
• Increased electricity bills: An inefficient AC unit can drive up electricity costs.
• Costly, frequent repairs: When not properly cleaned, your unit’s parts wear out faster, requiring costly, frequent repairs.
• Your house feels stuffy and uncomfortable to stay in. Also, sometimes the trapped moisture can lead to mold or mildew, especially around the drain pan or coils, causing musty smells and worse air quality.

Conclusion

Since a chemical wash is sometimes necessary, you should have the basic knowledge of what to expect during the procedure.

Mainly, and you have noticed in this post, the procedure is necessary and safe as long as a qualified professional company performs it.
