How to Clean an AC Unit's Outside Condenser Coil
How do you clean the condenser coils on an air conditioner?
Here's a quick rundown of everything, and we'll go over each step in
depth below. (Remember, the condenser coils are located outside your home.)
1. Unplug your air conditioner.
2. Remove the top and side covers from the condenser unit.
3. Remove the fan from the unit (this is an optional step).
4. Remove any debris from around (or within!) the device.
5. Vacuum any dust or grime from the unit.
6. Repair the condenser coil fins
7. Use coil cleaner to clean the coils.
8. Spray water onto the coils using a hose to remove dirt and dust.
9. Reassemble the air conditioner
Turn off the air conditioner's power.
Before you do anything, turn off the air conditioner and turn off the breaker. (The breaker can be found beside the unit or in a metal box near the outdoor unit.)
Please do not skip this step. It protects both you and your air conditioner. For full villa services click here.
Remove the top and side covers from the condenser unit.
Locate and remove the screws or nuts that are keeping the top cover in place (a drill can be useful here). Then repeat for the side cover. You don't have to be too delicate with these covers—they're designed to be removed for cleaning!
Make a container for all of these critical bolts and screws so you don't lose them when working outside.
Remove the optional fan from the unit.
Remove the fan from the condenser unit with a screwdriver or a cordless drill. This will allow you to have a better view of the coils and make cleaning them much easier.
By the way, if your device lacks the screws that hold the fan in place, or if the work appears too difficult, don't force it—just move on to the next stage.
Remove any debris from around (or within!) the unit.
Remove any leaves, sticks, or other debris that may be around or in the condenser unit (here is where gloves come in handy).
Remove any dust or grime with a hoover.
Remove any remaining dust or grime from the unit with a shop vacuum. Use the extension attachment on your hoover to get into all the nooks and crannies.
Install the condenser coil fins.
If the aluminium fins on the condenser coils are bent, use a fin comb to straighten them out by gently combing through the fins.
This isn't technically necessary, but it can help the unit work more efficiently and is a good idea to incorporate into the AC coil cleaning regimen.
Coil cleanser should be sprayed on the coils.
Once the unit is relatively dust-free, begin cleaning the coils. To begin, lightly moisten the coils with your hose. Set your sprayer nozzle to a broader setting to avoid excessive water pressure.
Use your common sense. You want to clean your AC coils, not pound them!
After you've wet the coils, spray the canned foaming cleanser—which we'll assume you're using—onto them and leave them for the time specified on the can (usually 5 to 10 minutes).
Spray water onto the coils using a hose to remove dirt and dust.
After the waiting period is over, rinse the coils with your hose.
For the greatest results, begin by spraying the AC unit from the inside out, beginning at the top and working your way down. This helps to keep soap residue from leaking onto clean coils.
Then, take a step back and hose the entire cabinet from top to bottom. (Avoid directing the water straight into the AC unit, as this may drive any leftover debris into the coils.)
Reassemble the air conditioner.
Allow the unit to air dry after the coils have been cleaned and soap-free. Then, replace the fan, reattach the side cover, screw everything back together, and reconnect the power to the AC unit.
Voila! A spotless outdoor air conditioner. However, you are not yet finished: Your indoor units will also require some maintenance, and there is no better time than the present.
How do you clean evaporator coils inside an air conditioner?
Now you'll learn how to clean your interior AC coils, also known as evaporator coils.
Turn off the machine and look for the evaporator coils.
Before you do anything, make sure the power to the AC unit is turned off (turn off the power at the breaker panel, not the on/off button).
Then, unscrew the screws, bolts, or other fasteners that are holding your indoor AC unit's access panel in place. The evaporator coils, which are the large, flattened tubes inside the air handler, should now be visible. They should be in an assembly that is generally shaped like the letter A. The interior of that assembly will be the dirtiest, so be prepared!
To avoid losing screws that hold your access panel in place, keep them in a plastic bag or envelope.It's also a good idea to photograph anything you disassemble so you Have a reference for reassembling everything.
Vacuum up any debris after brushing the coils.
Begin by removing any large bits of dirt or debris from the coils with the nylon scrub brush.
Starting at the top, work your way down. The purpose here isn't to get the coils absolutely clean, but rather to "jostle out" any large particles so they fall out of the coils and can be vacuumed up (use a light touch with the vacuum because the coils are delicate).
After that, use your fin brush to straighten out any flattened coils.
Clean the coils with the foam cleaner.
It's time to use the foaming cleanser to clean the coils. Spray a generous amount of cleaner into the coil assembly and let it sit for 5 to 10 minutes (as directed on the can).
After cleaning, you can lightly agitate any dirt or debris that is still clinging to the coils with your brush (or even just your gloved hand). Then, using a spray bottle, carefully rinse the coils. (Do not hose down your indoor unit. It will despise the experience, and your carpet will stink for days as a result.)
Reassemble everything after drying the coils.
To dry the coils as much as possible, use a soft cloth (a blow dryer will damage the coils). Alternatively, you can simply leave the access door open until the coils are completely dry. Either way works!
Then screw everything back together, re-start your air conditioner, and enjoy the cool blast of air from a pleased temperature control system. Is everything fine in the HVAC UAE?
