Baltimore is a rowhome city on gas heat: 50% of its 295,032 housing units are single-family attached, 15% are single-family detached, 10% sit in two- to four-unit buildings and 25% in buildings of five or more (Census ACS 2020-2024, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US2404000, checked 2026-10-21), 41% of those units were built before 1940 and 82% before 1980, with only 9% dating from 2000 or later (Census ACS 2020-2024, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US2404000, checked 2026-10-21), and of the 255,668 occupied homes natural gas heats 62%, electricity 31% and heating oil 3% (Census ACS 2020-2024, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US2404000, checked 2026-10-21). The rowhome sets the install: a two-story, 14-foot-wide brick row built in the 1920s has shared party walls, no side yard for a condenser pad and a gas boiler in the basement, so the outdoor unit goes on the roof, in the back alley or on a bracket above the front stoop, and the line set runs up the back of the house. The age of the stock matters because 41% of units predate 1940 and will not clear a weatherization check on age, so the audit and the air-sealing estimate come before the heat pump quote, not after, and the installer matches the system to the envelope the audit documents rather than the square footage on the deed.

The worst day to pick a heat pump is the day the old system dies. See the number now, decide later.
