Hi WorthFlorida, I really appreciate all the info you provided here. Sorry I read that several times but I still don't understand what's the current problem(s) you discovered other than the air filter issue(which needs to be replaced). You mentioned about the A coil, then curd inside the blower...

You also mentioned about the AC coils like breplum said today, could you please tell me a bit more? Sorry I am not familiar with this but love to learn. Thanks again!

Thanks breplum! Could you please tell me a bit detail about: 1. "shop to make up a cover panel and gasket them with peel and stick material from the hardware store for better efficiency": did you mean how to cover the filter slot on the side(the leaky style)? or should I simply tape it with...

Thanks for WorthFlorida and SShaw pointing out the filter type, so what type of filter should I buy for the "bottom" one to replace the existing mess one? I used 3M Filtrete "7"(1000) 16x25x1 for the side one. The model number of the furnace is York P3HUC16N09201C. Please advise. Thanks!

I confirm they are connected there is an opening between the furnace base(riser) and the bottom of the duct: Why the airflow needs to go two paths instead of just one? I wonder why the bottom should be connected, why the airflow can't just go through the air filter(red one, 16x25x1, slide...

I attach another photo above, and I will check and confirm if the base of the furnace connects to the right duct.

Yes, that's an electrostatic filter, I found a few in the house. Are the filters used to seal to the ground? I attach another picture with a better view below:

When I opened the cover of the furnace in the utility room at the basement level, the first time after I moved in to this house built year 2000, I was so surprised to find two air filters put right under the fan(please see the picture #1 below): one 16x25x1 old filter with dust, one old style of...

Thank you so much Dana, for all the details!

I heard a big cash sound yesterday when I was working in the house but I couldn't find why, until this afternoon when I went downstairs to the basement, I felt hot then I was shocked when I saw the humidifier fell on the ground with pieces and dust everywhere in the utility room, leaving a big...

What's the R wire for? I did a test in the past couple days, by disconnecting the G(green) wire: ************* Before disconnecting the Green cable ************* 10/12, SYSTEM=OFF, FAN=AUTO: I heard the very short(<1 second) buzzing sound(not sure if "buzzing" is the right word, but the...

I found the fan starts randomly(sometimes failed to start, when I heard very short buzz sound from the attic), so I doubt its behavior is usual. I think all the sensor is on the control board.

No, there is no humidistat or humidity control with my system. Thanks!

I recently noticed an issue with the HVAC system on the 2nd floor, the fan runs for a while(around half an hour or a bit longer) then turns off, several times a day even while I set SYSTEM=OFF, FAN=auto. The other system in the basement(covers 1st floor and the basement, two zone) doesn't have...
