A chipmunk brought down our air conditioner a few weeks ago. Where the A/C line runs underground, there was just enough space (about an inch) for the little bugger to burrow in and chew the insulation off the thermostat wire.

A repair tech advised me to fill the void with some spray foam insulation. Otherwise my wee rodent friend will come back to munch, and I’ll need to call the repair service again.

Amazing to think how much sabotage can be wrought by varmints that crawl in through little gaps in our lives. Makes me wonder what other “voids” in my life are leaving me vulnerable–and how I need to secure them.
