Guideline for your explicit consideration:
Purpose of the coil:
Air conditioner coils are of two types- evaporator coil & the condenser coil. The evaporator coil holds the primary responsibility of cooling air, whereas, condenser holds the secondary position of cooling.
There is a misunderstanding of people that the air conditioner does nothing for cooling air. The story occurs on the opposite, i.e., AC removes the heat from the flowing air.
Well, the fact is the evaporator do the work of extracting heat from the air and release it outside the building. Then a refrigerant cools the heatless air. The fan on top does the job of blowing hot air over condenser coils, and as a result, the coolant would lose some of the heat.
The optimal condition of these two coils is mandatory for your air conditioner to work correctly.
Operation between the AC unit & dirty coil:
Some people think, let it be. Does it matter if I use a dirty coil? Yes, it does.
The first and foremost disadvantage you will undoubtedly face is the reduction of the air’s coolness as the AC will not fully extract hot air. So, make sure to have contaminant-free AC coils.
In the long run, the dirt will be a substantial barrier to air and a drainage problem. But you have a plus point of easy recovery of such damages.
So, don’t perform the mistake of operating uncleaned coils with your air conditioner system.
What makes an AC coil cleaner good?
The most common question among the buyers is what it takes for a cleaner to be the beast of dirt. Let get some critical points that you must notice or ask the sellers during purchasing.
Typically washing component comes in acid-base nature. Although acid works excellent as a cleaning agent, the grime can be even stubborn & in the process, acid might damage the material of the coil.
Many will advise using only water, but an alkaline cleaner can also do the work of cleaning excellently.
The product needs to be easy-to-use and effortless. Many cleaners come in an aerosol container or may have an extra sprayer. Those are comfortable to use while spraying, and you don’t even need to rush for buying a sprayer.
Any product having USDA certification is safe to use as it means that they are safe near food. The certification also means that the cleaner doesn’t have any harmful particles causing the breathing problem.
The cleaners that are specially made for AC are expensive comparing to the general filter. Luckily, a little amount is enough for the long run.
All the cleaners in this article are budget cleaners and effective in works as well.

Instead of buying cleaners for specific parts, look for the versatile one. Both of them work the same. Besides, it will be worth it to buy a versatile one for washing any parts.
Zero harmful additives:
Though the chlorinated solvents speed up the process of cleaning, it is not suitable for your health as well as for the environment. It is a bit hard to look for a completely green cleaner. So, you should buy something ozone-friendly.
The steps of using the coil cleaners:
As I said above, it is something that needs too much care. So, let’s start the process according to the safety guidelines of the manufacturer.
At first, ensure that you have switched off the circuit breaker, and no power is flowing. Take the coil cleaner of your choice; just ensure that it is a quality product and a self-rinsing one.
1. For cleaning the indoor-service unit, the front panel needs to be opened over that position where it stops.
2. Separate the air filters.
3. Now slide the right-rotary-shaft to the left side & release it. Again do the same thing with the left-rotary-shaft to its opposite side and release it.
4. Then, unfasten the center shaft along with right and left shaft for removing the blade.
5. Take out your grille by removing the screws & hooks.
6. All is ready; it is spraying time. Shake the coil cleaner well before removing the cap.
7. Spray on the dirty surfaces.
8. Give some time to soak and perform foaming on the dirt.
9. After the foam has emulsified the harsh grime particles, rinse it off.
10. The technique to clean the outdoor unit is quite the same as the indoor one. First, unmount the outdoor unit setting & then spray the cleaner on dirt residual of the evaporator coil.
The rest of the process is the same as before- let it soak & rinse it off. I think that I have made the cleaning process pretty much clear. Even after that, if you are quite unsure regarding how to do then, don’t panic.
There are several tutorial videos on YouTube. You can go through any one of them, and you will be pretty clear about the process. Trust me; it’s not that critical.
