Forced Air Rumbling
I just bought a house that has propane heated forced air. I have a couple of questions. Is it supposed to kick in every few minutes even when the thermostat has reached the required temperature. The temperature however never goes past the desired level. (Does it do this to maintain heat level?)
The other question that i have is every so often when the furnace is on, i can hear rumbling coming from it. Not sure if this is supposed to be occuring.
Help would be great

Several Possibilities
Hi: Morgation
One of several possible reasons for the furnace to be cycling so often could be do to the heat anticipator setting inside the thermostat.
It's on the thermostat's body just under the front cover.
It looks like a rheostat indicator and usually has a pointer arrow.
The anticipator is used to balance the temperature swings between the desired room temperature and the actual temperature.
If the anticipator swing temperature is set too far, the room temperature will drop too low before the furnace cycles on.
Conversely, the furnace will remain on too long after the thermostats selected room temperature is reached.
Set too short, the cycles will happen all to often.
To obtain the all around best selected average room temperature, set the thermostats room temperature selection and then adjust the anticipator to one of the highest or lowest settings.
