We’ve been at this since 2018. Forty-two years means we’ve worked on the original steam radiators in Petworth rowhouses and the rooftop units above Georgetown commercial buildings. Washington’s not like Arlington or Alexandria. The Historic Preservation Office governs what you can bolt to a roof or punch through a wall. Our Emergency & Commercial HVAC team designs around those constraints every day.

Why Fireside Heating & Air Co. Is Washington’s Preferred Emergency & Commercial HVAC Company

Washington homeowners and property managers call us back because we show up when we say we will and we quote a price we stand behind. No voicemail trees. No bait-and-switch. A live person answers at 2 a.m. - including that Sunday night when your chiller goes down before a Monday opening.

Our reputation here is built on jobs done right in a single visit. Most of our Washington customers have lived in the same building for twenty years or managed the same property portfolio for a decade. They remember the last contractor who disappeared after the check cleared. We don’t work that way. The 90-Day Done Right Promise is written, not spoken. If something isn’t right, we make it right. No paperwork, no arguing.

Our response time to Washington averages under 60 minutes for emergency calls inside the District line. We know which alleys in Columbia Heights are wide enough for a service van, and we know that a “quick” rooftop repair on U Street often requires coordinating with a building manager who lives in McLean. That local knowledge saves hours on every job.

Our technicians are background-checked, uniformed journeymen who put on shoe covers without being asked. They treat your building the way they’d treat their mother’s. That’s not a slogan. It’s how we’ve operated since Glen Hartman founded Fireside in 1984.

Our Emergency & Commercial HVAC Services in Washington

24/7 Emergency HVAC

Your phone call reaches a live person, not a recording. Nights, weekends, holidays - it doesn’t matter. Washington’s summer dew points regularly exceed 70°F, and when a rooftop unit fails in that humidity, mold follows fast in these old brick buildings. We carry parts for Carrier, Trane, Bryant, and American Standard on every truck, and most emergency repairs in Washington are completed in one visit. Our $50 Off Any Repair Over $250 offer applies to emergency calls too.

Commercial HVAC

Commercial systems in Washington face a challenge rare in the suburbs: the building itself fights you. Pre-war brick rowhouses converted to offices, retail spaces with original radiator systems, multi-unit properties with no attic plenum for ductwork. We’ve retrofitted ductless mini-split systems into Capitol Hill historic townhouses, routed refrigerant lines through party walls in Shaw, and replaced entire commercial packages in Georgetown basements where no crane could reach. We give you straight talk about repair versus replace, and the price quoted is the price paid.

Rooftop Unit Service

Rooftop units in Washington take a beating that Maryland and Virginia crews rarely see. Wind-driven rain penetrates unsealed curbs. Debris from adjacent construction impacts condenser fans. And the Historic Preservation Office watches every penetration, every visible line set, every piece of equipment that faces the street. We design 50-60 ft refrigerant line runs through interior chases to reach approved rear or rooftop locations. During a severe summer thunderstorm, our crew responded to a commercial rooftop unit at a Capitol Hill historic townhouse that had lost its wind-rated curb seal. We installed a new Carrier rooftop unit with reinforced flashing and a hurricane tie-down system, rerouting the refrigerant lines 55 ft through an interior chase to meet Historic Preservation Office approval for rear-yard condenser placement.

Chiller Service

Chillers in Washington’s commercial basements and mechanical rooms suffer from the same humidity that makes the city miserable in August. Condenser water loops grow biological film. Cooling towers clog with river-basin pollen and urban particulate. We service chillers down to the tube bundle, and we’ll give you a free second opinion on any written estimate you’ve already received.

Trusted Brands We Service in Washington

Our trucks stock parts for nine major brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. In Washington, that inventory matters more than in most cities. A failed compressor in a Georgetown commercial building on a Friday evening doesn’t wait for Monday shipping. We carry Bryant and American Standard contactors, Trane TXVs, and Carrier capacitors because we’ve learned what fails most often in this climate. Fast turnaround means less downtime for your business and less humidity damage to your building.

Common Emergency & Commercial HVAC Problems We See in Washington Homes

• Wind-driven rain through unsealed rooftop curbs. Older commercial units on Washington’s flat-roofed rowhouses lose curb seals to freeze-thaw cycles and UV degradation. Water hits electrical compartments, causing short cycling and refrigerant leaks that look like compressor failure until you trace the real cause.
• Impact damage to condenser fans and coils. Construction debris, tree limbs, and wind-borne grit from nearby demolition bend coil fins and dislodge fan blades. Airflow drops. Head pressure spikes. The unit locks out on high pressure - usually at the worst possible moment.
• Loose roof fasteners under gust loads. Washington’s summer thunderstorms and occasional tropical remnants produce wind that shifts poorly anchored rooftop units. A tilted unit breaks refrigerant lines and electrical conduits. In historic districts, the repair often requires re-engineering the mounting system to meet current wind ratings.
• Humidity overload in poorly insulated brick envelopes. DC’s 70°F+ dew points overwhelm systems sized only for temperature. The thermostat says 72°F but the walls are growing mold because the equipment can’t pull enough latent load. Correct sizing and proper dehumidification sequencing solve what a bigger compressor cannot.

Our service area extends to Washington, D.C., Arlington, Alexandria, and McLean. Each jurisdiction has its own codes and its own character. Arlington permits differ from DC’s Historic Preservation Office requirements. Alexandria’s floodplain affects equipment placement. McLean’s larger lots allow simpler rooftop access. We know the differences because we’ve worked in all of them since 2018.
