During winter, if comfort in the house seems inconsistent, it may be necessary to take extra steps to heat frigid rooms that are stubbornly cool.
A particular room may not acquire enough yearly daylight exposure, or insufficient attic insulation can cause that section of the house to not hold heat efficiently.
Obviously, rooms located on a wing, separated from other residing spaces, plus not getting their fair share of heat will remain cold. There are many reasons why a room or rooms may not perform well when it comes to comfort. It applies to the vents in the colder rooms, and all other rooms in the house. When registers are closed in particular rooms plus left open in others, the oil furnace airflow through household ductwork may be unbalanced, resulting in some rooms receiving insufficient heat. Replace worn weatherstripping if necessary if frigid air is intruding around windows. Check for cracks at the joint between the walls plus ceiling or along the baseboards that may allow unconditioned air in. Silicone caulking can be used to seal these cracks. Depending on where the method temperature control is located, other parts of the house may have chronically low hot plus cold temperatures if it is located in a section of the house that is respectfully warm. If necessary, relocate the temperature control to an section where the temperature is representative of the entire house, rather than close to a heating vent or in direct sunlight. Consider adding a room-to-room ventilator if an adjoining room is usually warm, however the next door room is cold. They install into the wall between 2 rooms plus transport heat from the warmer room into the colder 1. With a temperature control so they only run when needed, room-to-room ventilators can be installed for as little as $100.
