Where are the air filters?

Roof mounted air conditioners have a thin mesh filter on the inlet air screen. The inlet air screen can be removed usually by depressing the clip on the edge of the screen. Here is a you tube video, ignore the first minute.

I don't believe the furnaces have any filters on the inlet air system; some owners have added outlet air register filters (after market).

Hope this helps,

Unless things have changed...the return air for the heater does not have one. A few years back, we were advised not to install one. It will restrict the air flow o the heater. On the new models, the A/C might a filter. On our older model, its a piece of foam at the return air in the ceiling.
