A cold draft near the front door makes the whole house feel colder than the thermostat says, and plenty of people respond by turning the heat up a few degrees. The cheaper fix is finding where the cold air is getting in. On a windy day, hold a stick of incense near window frames, door edges, outlets on exterior walls, and the attic hatch. If the smoke pulls sideways or gets sucked toward the gap, you’ve found a leak. Weatherstripping, door sweeps, and foam gaskets behind outlet covers cost very little and go in with basic tools. Sealing those gaps lets your furnace keep the house warm with less runtime and makes the rooms by the door a lot more comfortable. If you still have spots that won’t warm up after that, we can check whether airflow is the issue.
