I put a new one in return last night
I've heard something in crawlspace under house lately. Think clear now and blocked off. Animal might knocked some trunk lines loose.
Hard to get to indoor unit part down there.
If filter on it that needs replaced they've never told me what to use
Ceiling fans in 2 bedrooms.
78 in house. Bearable not comfortable. It's doing something or be worse.
If the filters were causing it, after you replace it, you need to turn it off for 8 hours to half a day or just run the fan to always be on, to thaw out the system. If blocked filters are causing it, your AC gets frozen and has to thaw out. Replacing the filter won't fix it, until you let it thaw out.
