Yep - all good suggestions. Not a one is incorrect above.
- definitely get that thermostat setting up into the 72-74 range.
- if the daytime temps are up in the 90s, put the AC(s) on high vice auto still with the temp setting in the 70s. Wear on the AC really happens when it cycles.
If these don't work, have you replaced your thermostat at all? I did - to a digital MicroAir version. The front AC fan would shut off before the compressor so I'd get a humm. Weird. Removed it and replaced with the old 5-button setup which you don't have with a 2021 and the problem went away. My point is, if you did any mods, something to consider!
