Step-by-Step Guide

  1. 1

    Turn off the power to the HVAC system

    Locate the circuit breaker or disconnect switch for your HVAC system and turn it off to ensure the system is not running during the cleaning process.

  2. 2

    Access the evaporator coil

    Locate the evaporator coil, which is typically located inside the air handler or furnace. You may need to remove panels or access doors to reach the coil.

  3. 3

    Clean the coil

    Use a coil cleaning brush or a vacuum with a soft-bristle attachment to gently remove any dust, dirt, or debris from the coil. Avoid using harsh chemicals or high-pressure water, as these can damage the coil.

  4. 4

    Rinse the coil (if necessary)

    If the coil is particularly dirty, you may need to rinse it with a mild, coil-safe cleaning solution and a low-pressure water spray. Be sure to dry the coil thoroughly before reassembling the system.

  5. 5

    Reassemble the system

    Once the coil is clean, replace any panels or access doors and turn the power back on to the HVAC system.
