I seem to get a lot of dust inside the home since the very beginning when the unit was first installed about 10 years ago. It' a very old house but I have checked the unit and it is completely sealed, so I do not believe it is picking up dust in the attic. I have tried electostatic filters and several other kinds (Not the cheap one), but the problems continue. We clean house today, change the filter, and tomorrow there is dust again. The inside coil is in the attic and I would like to clean it in place. Is this possible, a good idea or not? I have also heard that it is worrisome to use bleach because it must be rinsed out completely off the coil or it will cause damage to the coil. Is there something specific for cleaning the coil? Has anyone had a similar problem and if so, was it resolved, how?
Thanks
