Yes, I just had a Coil Cleaning
It was very needed. I was unable to catch my breath. Now, my other question has to do with my open door unit. I don't see an Air Handler on my Goodman Amana. The year purchased was 2014. I only have the framing on wall which connects to the A/C.
I need knowledge about this area. Do I put an Air Filter in this area? It tends to restrict the Air Flow. I really want to save her. Any ideas? Always wanting to learn! Thank You!

Is my garbage can to close to the air handler if it’s less than a foot away

Should my heat pump be on with the fan running while the air handler is operating in the wintertime?

do we need to install air handler if we move to "air packaged unit"?
