Basement cold and drafty — Los Angeles, California
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.

LA's dry heat and poor air quality from wildfires and smog make air conditioning and filtration essential. Many homes lack ducted systems and rely on mini-splits or window units. Santa Ana winds and extreme heat events strain cooling systems to failure.
