Washington, D.C.'s signature brick rowhouses create unique airflow challenges that worsen uneven heating and cooling. Shared party walls eliminate heat loss on two sides but concentrate all thermal transfer through the front and rear walls. Homes with southern exposure absorb significant solar heat through front facades, making front rooms 6 to 8 degrees warmer than rear rooms during summer afternoons. Original ductwork was often sized without accounting for this solar load variation. Three-story designs with mechanicals in the basement fight stack effect, where warm air naturally rises to upper floors regardless of where you need cooling. Narrow floor plans limit return air pathways, creating pressure imbalances that starve upper bedrooms of conditioned air while over-serving the main level.
