Capitol Hill's Victorian rowhouses, most of them built between 1865 and 1900 around Eastern Market and Lincoln Park, run on heating systems that don't fail gently. When a cast-iron steam or hot-water boiler goes cold at 2 a.m., a whole rowhouse loses heat fast, and a stuck zone valve, a tripped low-water cutoff, or a failed circulator can leave you shivering until morning. We dispatch around the clock so you're not waiting on a callback when the radiators have gone silent, and our trucks carry the parts these older boiler-and-radiator setups actually need rather than whatever fits a brand-new furnace.
Summers here bring the opposite emergency. So many Hill homes added cooling after the fact, central AC squeezed into tight chases or ductless mini-splits hung on the walls of rooms that never had ductwork, and that retrofitted equipment is exactly what tends to quit on the hottest, most humid afternoons. We handle the full range of after-hours calls: a condenser that won't start, a frozen evaporator coil, water pooling under an air handler in a finished basement, or the smell of gas near an old boiler that means you stop and call right away. Renters and landlords get the same urgency, because DC's habitability rules don't pause for a weekend or a holiday, and neither do we.
Capitol Hill note: Because Capitol Hill sits inside a historic district, exterior equipment like condensers and mini-split line sets often has placement and screening limits, so our after-hours techs prioritize getting your existing system running again rather than improvising a visible change that could draw a violation, then scope any compliant fix for daylight.

What It Costs
For emergency calls, our diagnostic fee runs roughly $75 to $200 depending on the system and the complexity of the problem, and that visit gets you a firm, upfront repair price before we proceed. After-hours service (overnight, weekends, and holidays) carries a surcharge of about $40 to $80 per hour on top of standard rates, which we always state plainly when you call. Because every situation is different, the best way to know your number is to call for a free estimate over the phone.
