Your AC is running. The fan is spinning. But the room itself is not cool. Sound familiar? The majority accuse the thermostat or the refrigerant. But honestly? In nine out of ten dirty coils are the actual problem. One of the least considered maintenance procedures is referred to as AC coil cleaning, and it is silently killing your cooling performance every day. We’re here to change that. Here at the AC Maintenance UAE, we have provided you with the step-by-step guide on what to do, what to use, and what not to do to ensure your system runs smoothly as it is expected to do.
Why AC Coil Cleaning Matters for Your Cooling System
Missing out on AC coil cleaning is as though you never wash your car filter and wonder why the engine is not running well. Dirty coils cause your system to work harder and consume more electricity and cool worse. It is such a little thing that can make a lot of difference.
What Happens When You Skip AC Coil Cleaning
Due to neglecting the routine process known as AC coil cleaning, the coil itself becomes covered with dirt and dust, and functions as a blanket that traps heat within the system. Your air conditioner will not expel or absorb heat efficiently, meaning it will run longer, work harder to no avail in cooling your space.
This will cause larger issues over time. Compressor damage. Refrigerant issues. Complete system failure. None of those is a cheap fix. That little cleaning is a lot of money saved.
How Dirty Coils Affect Your Energy Bills
This is what the majority of people do not consider. Your AC can take longer cycles to bring the temperature to the desired level using dirty coils. The longer cycles imply increased electricity. An increased amount of electricity translates into increased bills each and every month.
It has been found that soiled coils may add up to 30 per cent to energy use. That’s not a small number. Frequent cleaning will ensure your system is running smoothly and your bills are kept in check.
What You Need Before You Start Cleaning AC Coils
Remember to prepare the right tools and products before lifting anything. Going unprepared is how individuals destroy their coils or fail to hit spots altogether. This part is very easy to get right, and therefore, the entire process becomes easier.
Essential Tools and AC Coil Cleaning Chemical to Gather
You will need the following before starting:
- Screwdriver kit: to take down AC panels.
- Soft bristle brush: against loose dirt and debris.
- Garden hose or spray bottle: to rinse.
- Fin straighten up: straighten Fin.
- AC coil cleaning chemical: This is the most significant item on this list.
- Gloves and goggles: keep safe
- Towel or dry cloth: to dry off after rinsing.
Forget not to put in the ac coil cleaning chemical. Simple water is not going to dissolve the grease and dirt that accumulate over time. A proper cleaner will give a proper result.
How to Choose the Right AC Coil Cleaning Solution
Not all the ac coil cleaning solutions do the same. It has two major forms; self rinsing foams and rinse-off sprays. Self-rinsing systems are simpler for novices. Rinse-off sprays are more thorough, but additional work is required.
Always check the label. An ac coil cleaning solution must be non-acidic, aluminium fin safe, and must work with evaporator and condenser coils. We also at AC Maintenance UAE believe that it is always good to test a new product on a small part and then proceed to apply it to the entire coil.
How to Clean AC Coils Step by Step
It is at this point that the majority become confused. They either hurry it over or tend to avoid crucial steps altogether. Do this step by step, and you will reap some real results. The following is how to clean ac coils the correct way.
Step 1: Turn Off the AC Unit Safely
It is not necessary to leave the AC on any longer than that. Not just from the remote. Turn it off on the main power source or circuit breaker. It is unsafe and pointless to work on a live unit.
Allow the system 15 to 20 minutes to cool and then begin. This safeguards you and the internal components within the unit.
Step 2: Remove Debris from the AC Unit Coil
Unscrew the outer panel and inspect the ac unit coil. There is a good chance that you will find dust, dirt, leaves, or other debris resting on and around the coils. Removal of the larger pieces should first be done with a soft brush or your hand.
Do not run a vacuum with a powerful vacuum on the fins. They are easily bent, and when bent, their air flow is limited. Gentle is the word here.
Step 3: Inspect the Coils for Damage or Buildup
Before you apply anything, have a decent look. Inspect the fins, corrosion, or any evidence of refrigerant leaks, such as an oily residue around the coil area. But you can see when it gets serious, then you had better call in the experts before starting.
Cases of minor build-up are expected. That is what the ac coil cleaner is supposed to do. However, in case the coils appear physically damaged, cleaning will not help that.
Step 4: Apply the AC Coil Cleaning Solution Evenly
Shake your ac coil cleaning solution and use it. You should spray it all over the coil surface with care, not missing out any of the fins. Soak not one part and leave the other. Even coverage makes even results.
With foam-based cleaners, you will see it begin to bubble and enlarge. That’s it, working. When dealing with spray solutions, apply evenly and proceed to the next step.
Step 5: Let the AC Coil Cleaner Sit and Break Down Dirt
It is at this point that most individuals become impatient. Wait the time advised on the label of the ac coil cleaner. Usually 5 to 15 minutes. The grease, grime, and collected dirt on the coil surface require time to be broken down by the cleaner.
Don’t rush this. Cleaning it before the full extent of the dirt is loosened leaves you with a half-clean coil. Patience here is a real factor in the end product.
Step 6: Rinse the Coils Thoroughly with Water
After the cleaner has worked its job thoroughly, rinse out the coils with clean water. Use a gentle spray. Not a high-pressure jet. The pressure can flex the fins and force dirt further along into the coil rather than be washed away.
Rinse the inside out, according to the direction of the fins. Ensure that all the cleaning solution is removed. Remnant chemical debris may result in corrosion.
Step 7: Straighten Any Bent Coil Fins Carefully
When the coils remain accessible, check the fins once more. Bent fins prevent airflow and diminish the cooling capacity of even a recently cleaned coil. Strauss any curvature carefully with a fin comb.
Work slowly and gently. Fin combs cost very little and can be found in most hardware stores. This little measure is felt in the degree of efficiency of air passing through the cleaning of ac unit coil.
Step 8: Reassemble the AC Unit, Dry and Check for Leaks
Make sure that coils are reasonably dry before replacing the panels. Wipe the surface of any remaining water with a clean dry cloth. Next, reconnect the unit with all the screws and panels in their positions.
When reassembled, give a quick inspection around the unit to see if there is evidence of water leaks or loose connections. It all ought to appear clean, dry and safe before you proceed to the last stage.
Step 9: Test the System and Monitor Cooling Performance
Switch the power back on and operate the AC for about 10 to 15 minutes. Go up to the vents and touch the air. It must be a lot colder and heavier than it was. The AC coil cleaning worked.
Should cooling remain weak following a good clean-up, then it may be a refrigerant problem or a mechanical problem. In such an event, the team at AC Maintenance UAE is ready to assist with a complete system check.
Common AC Coil Cleaning Mistakes to Avoid
Despite the good intentions that people have in cleaning coils, there are always mistakes that they will make that will only prove to be more harmful than beneficial. The two largest of these we see every day.
Using the Wrong AC Coil Cleaning Chemical
This is likely to be the number one error. All types of coils cannot be safely cleaned with an ac coil cleaning chemical. Aluminium fins can be corroded with highly acidic cleaners. Non-brand household cleaners have a residue that attracts more dirt.
Always utilise a product that is designed to be used in AC coils. See the label and its compatibility with your coil material. Always consult a professional when you have any doubts about something.
Skipping the Rinse Step After Applying the Cleaner
Others use the cleaner and leave out the rinse because they believe that the foam will drip off. It won’t. The cleaning solution will remain on the metal and corrode gradually. Always wash back and forth regardless of the kind of cleaner you are using.
This is one of those steps which seem to be optional but in fact are not. The difference between a good clean and one that, in the long term, will be damaging to your system is a good rinse.
