Evaporator Coil Cleaning – (Step by Step Guide)

Evaporator Coil Cleaning – Step by Step Guide

If your air conditioner isn’t cooling the way it should, a dirty evaporator coil might be the reason. At HVAC Bee, we help homeowners in Woodstock, Cherokee County, and Cobb County keep their HVAC systems in peak condition. In this post, we’ll walk you through evaporator coil cleaning step by step so you can boost efficiency, improve airflow, and save on energy bills.

What Is an Evaporator Coil?

The evaporator coil is located inside your indoor air handler or furnace. Its job is to absorb heat from your home’s air and work with your condenser coil to release it outside. When the evaporator coil gets dirty with dust, pet dander, or mold, it restricts airflow and reduces cooling efficiency.

Signs Your Evaporator Coil Needs Cleaning

• Weak airflow from vents

• AC running longer than usual

• Higher energy bills

• Ice buildup on refrigerant lines

• Musty odors from vents

If you notice these signs, it may be time to clean your evaporator coil.

Step-by-Step Guide to Cleaning Your Evaporator Coil

Step 1 – Turn Off Power to the Unit
Always shut off your HVAC system at the thermostat and breaker before starting any cleaning.

Step 2 – Access the Evaporator Coil
Remove the access panel on your indoor unit to locate the coil.

Step 3 – Inspect the Coil
Check for visible dirt, dust, or ice buildup.

Step 4 – Use a Soft Brush or Compressed Air
Carefully remove loose debris with a soft brush or compressed air.

Step 5 – Apply Coil Cleaner
Spray a no-rinse evaporator coil cleaner evenly across the coil. These cleaners foam up and dissolve dirt as they dry.

Step 6 – Clean the Drain Pan
Flush the condensate drain pan with a mixture of warm water and mild soap to prevent clogs and odors.

Step 7 – Reassemble and Restore Power
Replace the access panel, turn the system back on, and check for improved cooling performance.
