Minimum furnace run time?

Daox · 12-31-12, 09:54 AM

I've always read that your furnace shouldn't short cycle. But, I was hoping that we can help further define short cycling. Is it 10 minutes, 5 minutes?

I just checked my TED usage and it seems that my furnace kicks in for a little over 30 minutes at a time to maintain temperature (ambient is fairly cold right now, say ~15F). I'd say 30 minutes is plenty long, but I'm not 100% sure. It then doesn't run for about an hour, and then turns on again for a little over 30 minutes.

So, what would you guys say is short cycling? What should be the minimum run time we should look for? What are other variables that we should be looking at to answer these questions to our best?
