The evaporator coil is responsible for absorbing heat from the air in your home. Over time, the coil can become dirty and clogged, which reduces its ability to absorb heat. As a result, your air conditioner will have to work harder to cool your home, which can lead to increased energy costs and premature wear and tear on the system. Here is a guide to cleaning AC evaporator coils inside your house.

The Role of an Evaporator Coil

The evaporator coils in your air conditioner play an important role in capturing heat from inside your home and converting it into cold air that is then dispersed outside. These coils are typically found inside your ductwork system and work in conjunction with the condenser coils to complete this process. By capturing the heat from inside your home, the evaporator coils help to keep your air conditioner unit running efficiently and effectively.

If the evaporator coils in your AC unit are not working correctly, it will affect the entire unit’s ability to cool down the air. The evaporator coils also help to remove humidity from the air. They work together with the condenser coils to take in air and cool it down. When there is moisture in the air, the evaporator coils will condense it and remove the moisture from the atmosphere. This helps prevent dampness and deal with high humidity levels.

Cleaning Evaporator Coils


1. Open your unit.


You will need to remove the access panel to clean your indoor coil. Make sure the air conditioner is turned off before you remove the panel, and be sure to keep the screws in a safe place. If your unit does not have an access door, one will need to be added.


2. Select cleaning products.


There are many different types of cleaning products that can be used safely on air conditioning systems. These products typically drain away through the system’s drainage components. Only use cleaning products that are approved for evaporator coils if your evaporator coils are very dirty.


Cleaning your AC evaporator coils is an essential maintenance task to keep your unit working efficiently. Dirty coils can cause the system to work less efficiently and increase your energy bills. Cleaning the coils once a month during the summer will make the job easier each time.
