the heat was on... whats weird is that it looks like it consistently happened in the early morning 4am-6am. Check out the image they sent me below:

I know the heater usually works, we use it all the time. I haven't noticed the temperature decline while the heater was on during those early morning hours because I was asleep. What could be causing this? Do i need to get an heating/cooling guy over to check it out?
