Basement cold and drafty — Chicago, Illinois
A basement that stays noticeably colder than the rest of the house or has persistent drafts usually points to insulation gaps, air leaks around the rim joist, unsealed foundation cracks, or inadequate HVAC duct coverage. An HVAC technician can assess duct routing and airflow, while a handyman or insulation contractor can seal air leaks and add insulation.

Lake effect weather creates extreme temperature swings — from -20°F winters to 95°F+ summers — meaning both heating and cooling systems work year-round. Furnace failures during polar vortex events are emergency situations, and many Chicago homes rely on aging boiler systems.
