Columbia Heights heats two very different kinds of buildings, and a furnace problem here rarely looks the same twice. In the brick rowhouses off 13th, 14th, and Park Road, we're often working on older gas furnaces tucked into a basement or a tight utility closet — units that have been retrofitted from boilers, share decades-old ductwork, and tend to fail on the first genuinely cold night when they're asked to run hard. A few blocks east near DC USA and the newer mixed-use mid-rises, the equipment is modern and compact: condo air handlers, sealed-combustion units, and smart thermostats that throw a fault code instead of a strange smell. We repair both, and we diagnose each on its own terms rather than guessing from a symptom.
A no-heat call in this neighborhood usually traces back to a handful of culprits — a worn igniter or a flame sensor coated in soot, a blower motor that won't spin, a control board that's lost the thermostat, or a system that's short-cycling because it's overheating against a clogged filter or closed-off vents. The repair we will never rush past is a cracked heat exchanger, because a hairline crack in an old rowhouse furnace can leak carbon monoxide into living space. We test for it, we're honest about what we find, and if a unit isn't safe to run we tell you plainly. Most furnace repairs in Columbia Heights land between $150 and $650, and you'll see the flat-rate price before we pick up a tool — no surprises after the fact.
Columbia Heights note: Many Columbia Heights rowhouses sit in or near the Mount Pleasant and Fourteenth Street Historic Districts, where exterior changes face review — so when an aging furnace needs venting or flue work, we keep the solution inside and code-compliant rather than touching the protected facade. In the newer condo buildings, we also coordinate around shared mechanical chases and HOA access rules so a single unit's repair doesn't stall on a locked utility room.
