The fan on the condensing unit of an air conditioner is often the first thing that needs to be repaired. The fan is protected by a cage that is meant to keep out birds and rodents. However, the cage does not protect the fan from water, dirt and other debris that could ruin its functionality. After some time, your fan blades can get rusty. Also, the output vent leading to the fan compartment can get blocked. This article explains how to clean your fan blades and remove blockages from the vents. These repairs are more preventative. If you perform these regular maintenance tasks, you can ensure that your fan remains fully operational over the years.
Cleaning the Fan Blade
To access the fan compartment you need to remove the bird guard. This is very easy to do with a basic screwdriver. You might need a power drill to get the screws off though, especially if they are rusted. Use a powerful flashlight so you can have full visibility when working inside the compartment. If your fan blades show any signs of rusting, you will need to clean them with a rust remover. Then, coat them with a metal rust protection solution. Both of these products are sold at home improvement stores. When you are cleaning your fan blades, inspect the main rod and bearings. Rusty bearings can cause your fan to spin incorrectly (and be noisy). Greasing the bearings is a great way to ensure that the blades spin as smoothly as possible.
Cleaning Vent Blockages
While the bird guard is removed from the unit, vacuum out the bottom of the compartment. Clean the floor of the compartment out so there is no debris. Then, from the outside of the unit, remove the hose coupling on the exterior side of the output. By loosening a hose clamp, you can easily remove the hose. This is where you are likely to find the most serious blockages. Shake the hose and listen for any debris inside it. Any debris that you remove will ultimately increase the productivity of your fan. By increasing the airflow into your home, you can usually adjust your thermostat by a couple of degrees.
