Dirty coils in the plentumona Goodman CKL30how to clean the coils myself.

If the coil has only small dust particles attached to it a degreaser such as Simple Green can be used in a spray bottle very generously applied to the coil from the top down, preferable from both sides of the coil. If damage is avoidable, a water hose may be used to wash the coil, though this is a very messy avenue to take. Many times special access holes in the plenum will have to be cut as the coil is not always accessible. For heavier buildups of larger particles mechanical cleaning is required. Great care must be taken not to bend or break the coil fins. We use specialized fin combs and brushes, but a stiff paintbrush can be used though it is much more time consuming. From time to time coils become completely clogged with dust particles. I have been known to pump down systems and completely remove coils, taking them to self-serve car washes to clean them. Depending on the severity of your coil, a professional cleaning may be necessary as we have access to specialized chemicals which facilitate the process. If you choose to clean the coil yourself make sure that you flush the drain line afterwards with plenty of water.
