The answer to 'how to clean evaporator coil' is to regularly clean the evaporator coil on your HVAC system. The evaporator coil is responsible for absorbing heat from the air inside your home and transferring it outside. Over time, the coil can become clogged with dust, dirt, and other debris, reducing its efficiency and leading to higher energy bills and potential system breakdowns.
To clean the evaporator coil, you'll need to access the indoor unit of your HVAC system, typically located in a closet, attic, or basement. Turn off power to the unit, then use a coil cleaning brush or compressed air to gently remove any visible debris from the coil. You can also use a coil cleaner solution, following the manufacturer's instructions carefully. Be sure to protect yourself with gloves and eye protection, and work in a well-ventilated area. After cleaning, replace any filters and turn the power back on to the unit.
