Indoor Coil Blower Section

Indoor Coils Require a Little More Care and Work To Clean. Even Though It Is Very Possible For You To Clean The Coil There Is a Very High Risk of Damage That Could Be Very Costly To You The Home Owner To Repair

Step 1

Start by selecting a good cleaner. This has to be something that will not damage the coils, some research on your part will be unnecessary. Once you have found and purchased your cleaner solution make sure to follow the direction on how to use it.

Step 2

Start by turning main power to the condensing unit. There should be a service disconnect with in 6 feet of the unit. Open the door to the disconnect and remove the pull handle. If you still are not sure your power has been turned off to the unit, go to the main break panel on your house and turn the power off there.

Note: If Power Is Not Off There Is A Risk of Personal Injury or Unit Damage

Step 3

After turning off power and mixing if not a premix solution. Apply the cleaning chemical to the coil. Avoid spaying the fan and service panel on the unit. Spay a nice layer of cleaner all around the coil.

Step 4

With a garden hose with no attachment rinse the coil very thoroughly. Do not use a no rinse cleaner. There is no such thing as a no rinse.

Step 5 

Repeat steps 3 and 4. After you have repeated the process wait about 10 mins for coils to dry enough.

Step 6

Turn the power to the condensing unit back on. Then go to the thermostat and have it call for cooling to make sure the unit comes back on. Depending on how you turned the power on the system maybe in delay so don’t panic. If the system has not come on after 10 mins then recheck the thermostat and that you have turned the main power on.

Do NOT open the top section of your unit to spray the coil from the inside out. You will very likely damage the fan blade, or create a refrigerant leak.
