How could this indicate an HVAC issue? That's actually the least likely being as how common Window condensation is.This could indicate an HVAC problem. Where are you? How old is the house? How old is the heating system? What type of heating system is it?

I'm willing to bet the OP has old Pella casement windows or older double hung
Here's my 2c and please anyone feel free to correct me if my logic is flawed.
1) inside condensation is always on the bottom of the glass because that's where the any outside moisture will sit via the outer portion of the runoff sill, this area is most vaunerable because now that area has the biggest "delta T" (temp differential between outside draft and inside heat). Add outside draft to inside warm air (even if inside air is dry from heating), and you'll have condensation regardless!
What you can try is to keep ceiling fan on at night. What style of windows you have?
We've gone though a number of scenarios on this problem. It seems the OP has an excess moisture problem within the dwelling. The bottom line is that the excess moisture has to be eliminated. That can be done several ways. He indicated the prior owner took a dehumidifier with them. Perhaps acquiring another dehumidifier might solve the problem.
Perhaps opening all of the windows and airing out the house might solve the problem. (It's probably pretty cold right now in Canada, so this might be an issue)
Running fans (ceiling and box) might solve the issue.
I would also want to determine where this excess moisture is coming from.
