Dirty Air Handler

Had a tenant for 2 years that just moved out...shocked and horrified to just noticed he never bothered to use a filter for the AC. The slot where the filter goes - nothing there and I looked up and it's filthy.





These "filaments" are very delicate, and I have a water heater right below this opening. Any tricks of the trade you can recommend on how to clean this up?

Thanks in advance.

It's going to have to be sprayed with coil degreaser/cleaner and rinsed clean.

It's going to be a messy job.

Is it done "in place" or do you have to remove it and do it outside?

It is usually cleaned in place. It's pretty hard to remove with the system charged.

What might help is if you first used a stiff brush and carefully comb along the direction of the fins.
A hand wire brush works well.

Often the dirt is on and near the surface and much will be remove this way.
