Capitol Hill is one of DC's oldest and largest residential historic districts, and its housing tells the story. The brick and frame rowhouses lining the streets between the Capitol, Eastern Market, and Lincoln Park were mostly built between the 1860s and 1900, which means heating and cooling them is rarely a plug-and-play job. Many of these homes still run on the original steam or hot-water boilers and cast-iron radiators they were designed around, and keeping that equipment safe and efficient takes a technician who actually understands old-system heat, not just modern forced air. Our licensed crew works on Hill boilers, radiators, furnaces, heat pumps, and central AC every week.
The cooling side is its own puzzle. Most Victorian rowhouses were never built with ductwork, so homeowners here juggle a mix of retrofitted central air, window units, and increasingly ductless mini-split systems that cool the house without tearing into original plaster and trim. We help Capitol Hill residents repair what they have and plan smarter upgrades, whether that means nursing an aging boiler through another winter, adding a high-velocity or ductless system to a home that never had AC, or sorting out a third-floor bedroom that bakes in July while the parlor stays cool.
Because the Hill sits inside a protected historic district, even something as routine as placing an outdoor condenser comes with rules and tight spaces to work around. We're used to fitting equipment into narrow side yards, rear courtyards, and shared alleys, and to working cleanly inside finished homes where the woodwork and floors matter. From a no-heat call on a freezing January night to a mini-split install before the first heat wave, we show up with upfront flat-rate pricing, a satisfaction guarantee, and the kind of care these century-old homes deserve.
