HVAC Repair in Foggy Bottom, Washington DC

Same-day HVAC repair, installation, and maintenance for Foggy Bottom's historic rowhouses, GWU-area condos, and high-rise apartments — licensed, insured, and available 24/7.

Foggy Bottom is one of Washington's oldest pockets, and its heating and cooling needs are just as layered as its history. Tucked between George Washington University, the State Department, and the Kennedy Center, the neighborhood pairs surviving 19th-century brick rowhouses — including the tiny preserved alley dwellings around Snows Court and Hughes Mews — with mid-century institutional buildings and newer condo towers near the waterfront. Each of those building types asks something different from an HVAC system, and we work on all of them.

The older rowhouses here were never designed for central air, and many still run on aging boilers feeding cast-iron radiators or steam heat. We repair those original systems, balance uneven radiator heat, and — where homeowners want quiet, efficient cooling without tearing into plaster walls — install ductless mini-splits that fit the tight footprints these homes demand. For furnace and heat pump systems we handle furnace repair, heat pump service, and full AC replacements sized correctly for compact District floor plans.

Foggy Bottom also has a large share of condos and apartments serving GWU students, faculty, and longtime residents, where shared walls, rooftop units, and limited mechanical access make a knowledgeable technician essential. Whether you're a homeowner on a leafy side street or a resident in one of the high-rises along New Hampshire Avenue, we show up fast, diagnose honestly, and quote upfront flat-rate pricing before any work begins — backed by a satisfaction guarantee and 24/7 emergency service when the heat or AC quits.

FAQ

Foggy Bottom HVAC Questions

How much does HVAC repair cost in Washington, DC?

Most HVAC repairs in Washington, DC run between roughly $150 and $500, with simple fixes like a capacitor or fan motor on the lower end and major component work going higher. Expect a diagnostic or service-call fee of about $75 to $200, plus labor of roughly $75 to $150 per hour. Rates in the District tend to run higher than the national average, so always get an itemized, upfront quote before authorizing work.

Do you offer 24/7 emergency HVAC repair in DC?

Yes. We offer 24/7 emergency service for situations like a complete AC failure during a heat wave or no heat in winter, including nights, weekends, and holidays. A true emergency is generally a no-heat, no-cool, gas-smell, or active water-leak situation that can’t safely wait until normal business hours. Call us any time and we’ll dispatch a technician fast.

What counts as an HVAC emergency versus a repair that can wait?

Treat it as an emergency if you have no heat in freezing weather, no cooling during dangerous heat, a gas or burning smell, sparking, or water actively leaking near electrical components. These pose safety or health risks, especially for infants, elderly residents, or anyone with medical conditions. Issues like a slightly noisy unit, weak airflow, or a higher energy bill are real problems but can usually wait for a scheduled appointment.

How long does an HVAC repair usually take?

Most AC and furnace repairs are completed the same day, typically in one to four hours. Diagnosis usually takes 30 to 60 minutes, simple repairs like a capacitor or fan motor run one to two hours, and more complex jobs can take three to four hours. The main thing that stretches a repair into multiple days is when a special-order part is needed for an older or less common system.

Why is my AC running but not cooling my house?

The most common causes are a clogged air filter, an incorrect thermostat setting (such as the fan set to ON instead of AUTO), or a dirty outdoor condenser coil blocked by leaves and debris. You can safely check the filter, confirm the thermostat is on COOL, and gently rinse debris off the outdoor unit. If those don’t fix it, the problem is likely a refrigerant leak, frozen evaporator coil, or failing compressor, which require a licensed technician.
