Most Peculiar

Bizarrely, every time my AC comes on, my HDMI router blinks to another source. I'll be watching something through my cable box, the AC will come on and suddenly it's switched to an unused HDMI input.

I can hear my thermostat click from where I usually watch TV. It will click, and I lose the signal. I have to grab the remote and switch it back.
