Know-How To Clean Ac Coils Without Technician

Are you worried about how to clean ac coils?

On a hot, humid summer day, there’s nothing quite like stepping into a cool, comfortable home. Willis Carrier invented modern air conditioning in 1902, and we’ve been enjoying it ever since. It isn’t easy to imagine life without it for the vast majority of people. 

However, just like any other mechanical device, an air conditioner and its numerous components require routine cleaning and maintenance to function properly. When you buy a new car, you know that the oil changed, and the wheels balanced and rotated is essential to keeping it running at its best. 

Cleaning your ac condenser coil is essential for the system’s long-term health when it comes to central air conditioning. Cleaning the coils on your air conditioner can save you money, keep it running efficiently, and extend the system’s life.

In this article, I will guide you to clean your ac condenser coil on your own without spending on the technician. But for that, you need to understand the operation of your AC.

I often feel we put off some “tasks” because we don’t understand why they are necessary and, as a result, we prioritize them incorrectly. Perhaps gaining a better grasp of how air conditioning works would drive us to keep up with this maintenance and help us see why it is worthwhile.

An Air Conditioning System Has Three Primary Components

An Air Conditioning System Has Three Primary Components.
An Air Conditioning System Has Three Primary Components.
  • Condenser: This is the exterior unit that keeps the entire process running. As the gaseous refrigerant returns to the condenser, it goes through all those coils covered in fins and around the compressor, containing the heat it has taken from the house.
  • Evaporator: This is the interior component of your furnace or air handler placed on the top. The liquid refrigerant travels through some measuring mechanism when it enters the coil. In a nutshell, the device regulates the quantity of refrigerant that enters the coil. The tubing diameter has been raised.
  • Line set: The two copper tubes that transport refrigerant between the condenser and the evaporator are known as the condenser and evaporator tubes.

Why Is It So Important To Clean Air Conditioning Coils?

Dirt, dust, debris, and other pollutants may accumulate on the coil surfaces due to the close spacing between the coil fins, surface wetness from the cooling process, and the volume of air that travels over them. This accumulation limits the system’s capacity to transmit heat into and out of the house over time, limiting its capacity to offer summer cooling.

Dirty coils may also obstruct or restrict the airflow critical to the whole process in severe circumstances. Because of the decreased energy efficiency, this might lead to a less pleasant household and higher electricity expenses.

Worse, dirty coils force the system to work harder than it should, resulting in a shorter system life and possibly high maintenance costs. The cleaner the air conditioning coil is, the more effective the system will be.

Dirty coils may cause a variety of issues, including:

  • Temperatures of operation have been raised. 
  • Comfort has been compromised. 
  • Cooling efficiency has suffered as a result of this. 
  • Costs of cooling have increased. 
  • Corrosion on the system has increased. 
  • Repairs or replacement of the system.

When the ac condenser coil becomes dusty, it obstructs heat transmission, which is necessary for effective cooling. It makes the compressor work harder, raising the total operating temperature of the machine and, over time, limiting its lifespan.

Is it OK to spray water on your air conditioner?

The good news is that if your air conditioner requires cleaning, you can spray water on it, and nothing negative will happen. Spraying water on the condenser of your air conditioner can also help it operate more effectively. Spritzing your condenser frequently is required for it to continue to function properly.

Can you clean AC coils yourself?

The professional will most likely remove heavier debris by hand or with a special brush before using a self-rinsing evaporator oil product to clean your interior evaporator coil in ac. When the system is switched on, this solution will clean the coil properly and rinse it throughout the cooling process.

Does cleaning AC coils really help?

Surprisingly, dirty ac condenser coil often outperforms clean ones. For the coils we examined, condenser coil heat transfer performance varied from a 7% rise to a 7% reduction. There was no change on average.

Can I use vinegar to clean AC coils?

Yes, vinegar can be used as an AC coil cleaner. Fill your spray bottle with water, vinegar, and your spray bottle. Inside the bottle, combine 12 oz. Water and 12 oz. Vinegar.

Apply the solution to the evaporator and condenser coils after thoroughly shaking them. Vinegar is a very powerful cleaning that does not hurt the components.

How Do I Know If My AC Coil Is Dirty?

An overall decline in system pressure is the most visible indicator of a filthy evaporator coil in ac. You should identify whether the present pressure is below the typical pressure for your system if you know what that level is. If that’s the case, a clogged evaporator coil is most likely to blame.

Cleaning the condenser coils on your air conditioner regularly will allow it to run cooler and use less energy, making you feel more comfortable. Cleaning your air conditioner in the spring, just before you need to use it for the first time of the year, is the optimum time to do it. If you notice any issues with your air conditioning equipment while cleaning it, call a trained professional to get them fixed.

If you can’t afford to buy ac cleaning kit, the methods below will still help you improve the health of your air conditioner by describing how to disassemble the unit and what you can do with what you already have.

To clean your air conditioner’s coils, you’ll need the following items in your ac cleaning kit.

  • Hose
  • Drill or Hex Driver.
  • Using a toothbrush or a soft paintbrush is a great way to get
  • Bottle for spraying
  • Coil Cleaner
  • Zip ties and wire ties are two different types of ties that may be used.
  • Cuts from the side
  • Comb made of coils
  • Gloves that are not absorbent

Here are the steps to follow in cleaning your ac condenser coil

Shut off the power to the condensing unit and turn off the air conditioning at the thermostat

  • The handle should be disconnected
  • The disconnect handle has been removed.
  • Fuse holders are located on this disconnect. Let’s not lose sight of where they are located. Those are simple to swap out.
  • The panel of Circuit Breakers, One of them, should be set aside for your air conditioner.
  • Panel for accessing the condenser. You’ve removed the disconnect and turned off the thermostat, so there’s no electricity.
  • First, switch off the air conditioning at the thermostat and cut off the electricity to the condensing unit. 
  • It may be accomplished by disconnecting the stab connection or fusing the disconnect installed on the home near the device. 
  • The terminal should come out if you pull the handle that you see. 
  • Shut off the electricity at the breaker panel if you don’t have a disconnect for whatever reason. 
  • Your air conditioner should have its circuit breaker.
  • If your A/C disconnect has fuses, they are quite inexpensive and simple to repair.
  •  Make certain that the fuses you purchase are the same amperage as the ones you already have. 
  • Installing a fuse with a larger amperage capacity will not safeguard the machine as well as it should. In domestic air conditioning systems, the most common fuses are 20 and 30 amp fuses.

Take off the Condenser’s top

  • Remove the bolts that hold the top of the unit together. It will be made easier with the use of a drill.
  • A drill may not fit between the unit and the house in certain circumstances, so you’ll need to use another piece of equipment to get between the two.
  • Now that the nuts are removed, the top should be able to come off. You don’t know how much wire slack you have yet, so proceed with caution.
  • Electrical access panel for the condenser.
  • I’m sure there’s some cleaning up to be done within the panel.
  • I needed some more wire slack, so I will cut the wire tie to acquire it.
  • I’ll be able to feed the additional line toward the fan now that the wire tie has been severed, allowing me to lay it on the ground or another firm surface without having to disconnect it.
  • When you’re through with the work, remember to tie the wires back up. Only use a wire tie that is entirely made of plastic.
  • It is a nice area to position the top and fan after you have the slack you need.
  • There are many options for obtaining the slack you want. Just make sure the wires aren’t rubbing against any rough edges as mine are.
  • Remove the bolts that hold the top of the unit together. It will be made easier with the use of a drill.
  • Remove the top of the condenser while the electricity is turned off. 
  • Remove bolts that connect the lid to the remainder of the condenser, but leave the bolt, hold the fan to the lid in place. As illustrated in the photographs, keep the fan connected. 
  • These bolts, which are normally 1/4″, 3/8″, or 1/2″ in diameter, may be removed using a hex driver or drill.
  • Remove the fan-attached cover and set it aside. If you don’t have enough slack in your wiring, it’s most likely because the slack is wrapped up within the access panel.
  • You should extract the slack you want if you remove the access cover and cut the knot on the wires. 
  • Again, there is no risk of shock since the power is turned off; just be careful not to damage or nick the wires when cutting the knot.
  • As you rotate the lid around to a firm resting location, be sure the metal on the device does not cut or nick the wires. 
  • Cleaning up the webs and debris within the access panel with a paper towel or paintbrush is a good idea at this point.

Remove the Caging

  • Remove the fasteners from the cage’s bottom.
  • The cage should come off quite easily but proceed with caution.
  • Our coils are now visible, and we can see how dusty and damaged they are.
  • Remove the fasteners from the cage’s bottom.
  • We should be able to remove our shackles now that the top has been removed. 
  • Even if a metal shell or cabinet surrounds your condenser, the principle remains the same. 
  • Remove the nuts that connect the unit to the cage at the bottom of the unit, and it should come apart rather easily. 
  • Again, take caution because we don’t want to break any more of those fins than we already have.

Remove any debris from the unit’s base

  • It is the mess we need to clean up around the compressor at the bottom of the unit.
  • It is completely unsuitable for our flat.
  • That’s a squeaky-clean compressor and foundation.
  • It is the mess we need to clean up around the compressor at the bottom of the unit.
  • Clear the debris from the compressor’s location at the bottom of the device. When the unit is not in use, leaves and other natural gifts fall into the top of the unit. 
  • When they become wet and decay in the unit, they encourage corrosion and, in the summer, they create a layer of insulation beneath the compressor, reducing the airflow needed to keep it cool.

Comb out the smashed fins

  • Your efficiency will be harmed if your fins are smashed. 
  • On the other hand, areas this severe may not be combable and should be avoided if they are.
  • As you comb through the fins, gently move the comb tool from side to side.
  • Your efficiency will be harmed if your fins are smashed. On the other hand, areas this severe may not be combable and should be avoided if they are.
  • We’ll start by opening up the fins so we can clean the area between them. It is when the small air conditioner coil comb comes in handy. 
  • If you don’t utilize the side of the comb with the right spaced teeth, you’ll end up causing more harm than good.
  • Also, if any spots are resistant to the comb, do not push them through them. These very tiny metal bits will be ripped apart by you.
  • As you work your way through a dented area, wiggle the comb a little.
  • Finally, if you don’t have this comb, a butter knife or something similar might be used. The only disadvantage is that it is a little more time-consuming.

Prepare the Unit for Soaking

  • Inhale deeply and spray from the inside out.
  • Even if you have a self-cleaning product, give the condenser a good rinsing. 
  • Grass likes to grow on the coils’ outside edges.
  • Inhale deeply and spray from the inside out.
  • Go ahead and hose down that thing. 
  • To push back what was attempting to be drawn in, spray from the inside out. 
  • While you should avoid spraying directly at the disconnect or the electrical components within the access panel, a splatter here and there won’t harm. 
  • Aside from that, she’s free to do as she pleases. Water won’t hurt it since it was designed to be outdoors. 
  • Pay special attention to the unit’s exterior base, where higher grass deposits are likely to accumulate.

Using your cleaner mix, spray the coils down.

  • Clean the coil’s outside using a generous amount of cleanser.
  • And from the inside, there’s still another excellent helping hand.
  • Clean the coil’s outside using a generous amount of cleanser.
  • Apply a generous coil cleaner to the coils in the front and rear, from bottom to top. Allow the cleaner to rest for a few minutes before rinsing it off. For mixing ratios and stand time, refer to the instructions supplied by the coil cleaner’s manufacturer. 


I hope by following this guide you can easily get an ac cleaning kit and, with a variety of kitchen items, can make coil cleaner to clean your AC this summer without investing in the professional.
