My AC wasn’t cooling the house down. It was 85 degrees inside the house. I used this video to clean my AC Unit outside and it fixed the issue. Thank you!

While cleaning out the leaves, dirt, twigs, etc. from the bottom, also check that the drain holes are open and remove anything that will prevent free flow of water thru those holes/openings. Doing so will help to prevent premature rust formation in the bottom because it will be able to dry out. Also, check visually that the blades in the fan are not bent or out of balance or alignment as this will create unnecessary wear on the bearings and excessive vibration. Just give it a spin with your hand and watch the blades. You will notice any misalignment.

It makes tremendous sense and logic to clean the fins from the inside out. The air has dirt in it and other contaminants as evidenced by air filters for motor vehicles. As the fins become more and more imbedded with dirt, grass, twigs, leaves, etc. the airflow is reduced accordingly and the cooling efficiency suffers/drops off. The system works longer, harder, to bring down the air temperature in the house and more $ as well to get the desired cooling.

Thank you so much this was really helpful to me I'm a single woman taking care of my mother and a house trying to keep up with everything, and keep the AC running well this really helped me thank you so much 😊👍

Thank you so much for this video. Super helpful and well-presented. Your time and effort is most appreciated!

Great content, well done. I came here seeking help for an AC unit that just couldnt keep up. Following this tutorial my AC went from running all the time and not being able to hit the desired cooling temperature to running sporadically and holding the temperature as set. Thanks!

Good info but let me suggest a couple of tips. If the coil is not too dirty, skip the cleaner. Also, while you have the unit open AND POWER OFF, check the fan and make sure it moves freely. If it doesn't spin freely, motor may need lubrication or replacement.

I used 3 cans of cleaner. Had to unplug and removed fan assembly. Covered every fin area inside & out with foam about half of a side at a time. Didn't spray foam both sides, inside & outside, at the same time. First inside, rinsed then outside. Rinsed thoroughly till it ran clear. Rinsed from the side that had the foam. When you get it clean you can see your progress by looking through the fins. As a tech stated elsewhere, about 15% of the dirt is inside, the overwhelming majority is outside. I tried two Lowes brands, much preferred the Arm & Hammer to the brand in the video. Better and more powerful spray pattern.

[johnathanhardin]

I cover mine with a tarp during the winter months, I have never had to clean it and still looks new. I do periodically during the summer give it a good rinsing.

[DOMINYPAUL]

Good info at least for me on the outside unit, I'm going to do this. Thanks be blessed. P.W.D.
