Boiler & Radiator Repair in Washington, DC

Last updated November 5, 2026

If one radiator in your Washington home is hot and the next is cold, the boiler may be fine and the problem may be air, a valve or the circulator. We take boiler & radiator repair calls from every corner of Washington, Brightwood included, around the clock.

How we handle it

We explain what an old boiler still has left in it and what a replacement would involve, without pressure either way.

Boilers in Northwest DC rowhouses are often decades old, and parts like circulators and zone valves wear out. We carry common parts to fix most problems on the first visit.

Washington homes

Northwest DC is mostly early 20th century brick rowhouses, semi-detached homes and converted condo buildings, with larger detached houses near Rock Creek Park.

Northwest DC has one of the highest shares of radiator heat in the region. We see original cast iron boilers next to new high-efficiency combis, and both need correct pressure, working circulators and air bled from the top floor.
