Around 7 or so in the evening I start to hear a rattling noise coming from the furnace. It kind of sounds like something is in the duct and is floating in the air flow bouncing off the ducting walls. Anyone know what could be going on?

I'd ask the installer or an HVAC guy to look into it.

My daughter's house has the same make and they run it constantly using the same installer's questionable advice. I was alone at their house recently and they were at work. The place was cold and I wished I had had a sweater. We both have Lennox units. Comments?

I never received any such suggestion from my installer. He did mention the two main reasons for AC units to fail is setting the temperature too low and having a unit too small for the home.
I don't run AC when I'm not at home. I have a nest and away mode triggers. I turn it on around the time I get home and let it run until I hit the targeted temperature.
When I was away for a week, I set my thermostat on eco mode and AC was completely off all that time. The same happens in Winter, so it's not a big deal.
