Your system sounds like a pretty typical forced air system with a central return. Other than the noise, it sounds like it’s operating like it should. It may,however, need some adjustments.

Where are the heat registers in the bedrooms, and where is your thermostat? Can you adjust the flow thru the registers?

The system is going to cycle based on the temperature at the thermostat. If the furnace comes on when the bedrooms are comfortably warm, it may be necessary to partially close the registers in rooms closer to the furnace in order to increase the flow of warm air to registers further away. This will balance the flow of warm air throughout the house, and – hopefully – get the thermostat in sync with what you want for comfort.

As far as the noise issue, I would definitely call the HVAC folks back. Restricting flow at the return line probably isn’t the best solution, but they might be able to do something to cut the noise.
