Depends entirely on the system, but in general it should not be too oversized so that it runs for just a short time. Longer, slower heating cycles are more efficient.

Answer 2

Yes especially if its a heatpump.  Its normal but also could be issue depending on your service record on it.  If everything is good then don't worry heatpumps are more efficient than strip heat down to -5 course thats under perfect weather conditions. 

Answer 3

30 degrees F? yes. quite normal

Answer 4

Invest in a cheap digital room thermometer. Then you will have an accurate figure to work on.

Answer 5

Fahrenheit or centigrade? 30 degrees F is below freezing, so yes, but 30 degrees C is a hot summers day so no heating should be necessary.
