How to Identify Evaporator Coils
In order to clean your central air conditioner evaporator coils, you first need to be able to identify them.
Evaporator coils are typically located on the outside of the air conditioning unit and are easily recognizable.
The coils will look like a series of metal tubes or fins.
These tubes or fins are usually covered with insulation to protect them from the elements.
If you look closely, you may also see a small drain pan underneath the coils.
This is where condensation gathers and can be emptied periodically.
Once you have located the evaporator coils, you can begin the process of cleaning them.
Materials Needed to Clean Coils
When it comes to cleaning central air conditioner evaporator coils, there are several materials that may be necessary.
Depending on the type of coil cleaner being used, it is important to have the correct materials on hand.
Some of the most commonly used materials for cleaning coils include a brush or vacuum, a coil cleaner, a garden hose, and a ladder.
The brush or vacuum is key for manually removing dust and debris from the coils.
It is important to choose a brush or vacuum that is specifically designed for coil cleaning, as other brushes or vacuums may not be able to reach all the tight corners of the coils.
A coil cleaner is also necessary for cleaning coils.
Coil cleaners are designed to be sprayed directly onto the coils and can help break down any dirt and debris that may be difficult to remove with a brush or vacuum.
It is important to follow the instructions on the product carefully, as some coil cleaners may need to sit for a few minutes before being rinsed off.
Additionally, a garden hose is necessary for rinsing off the coil cleaner and any dirt and debris that has been removed.
A ladder is also necessary for accessing the coils if they are located in an area that is difficult to reach.
In some cases, additional materials may be needed in order to properly clean the coils.
It is important to take the time to research and prepare the necessary materials prior to beginning the cleaning process.
Manual Cleaning Steps
When it comes to cleaning your central air conditioner evaporator coils, there are two main options: manual cleaning or using a specialized coil cleaner. Manual cleaning is the most cost-effective and straightforward way to clean the coils, and can be done without any special tools or products. To begin manual cleaning, first turn off the power to the HVAC unit at the circuit breaker. Then, remove the access panel on the unit and locate the evaporator coils. Use a brush or vacuum to thoroughly scrub the coils to remove any dirt or debris. Then, use a damp cloth to wipe down the coils. Finally, turn the power back on and check the unit to ensure it is running properly.
When cleaning your evaporator coils manually, its important to take safety precautions such as wearing protective glasses, gloves, and a dust mask.
Its also important to use the brush or vacuum in a gentle scrubbing motion, as too much pressure can damage the coils.
Additionally, be sure to keep the coils wet throughout the cleaning process, as dry-cleaning can damage the unit.
Finally, be sure to check the access panel and any other parts for damage or wear before reassembling the unit.
