Furnace Repair in Petworth, Washington, DC

Last updated November 5, 2026

Gas furnaces in Petworth rowhouses work hard from November to March, and the weak points show up on the coldest nights. That is exactly when our phones are answered. We take furnace repair calls from every corner of Petworth, Upshur Street included, around the clock.

Systems we find in Petworth

A lot of Petworth rowhouses still have their original hot water boiler and radiators, while renovated homes usually switched to a basement gas furnace or a heat pump with a closet air handler. Rooftop condensers are common because rear yards are small.

Petworth furnaces usually sit at the back of a narrow basement beside the water heater, and many still vent through an old chimney liner that needs checking. If the liner is cracked or blocked, exhaust can spill into the basement, so we test draft before calling any furnace repair finished.

Signs you need furnace repair

• Board flashing a fault code
• Rumbling or booming when the burners fire
• Pilot or hot surface igniter not glowing
• Furnace runs nonstop but rooms stay cool

How we handle it

Diagnosis comes first, a written price second, the repair third. If the furnace is old enough that repairing it makes little sense, we tell you that plainly and show you both numbers.

Before calling about a Petworth furnace, check the basement door to the back yard: if the furnace room shares space with laundry, lint on the return grille can starve the blower and trip the high limit switch.

What we run into in Petworth

The calls we see most in Petworth: boilers that will not hold pressure, radiators cold on the top floor, and condo heat pumps whose closet drains back up in summer.
