We do both. Our Emergency & Commercial HVAC team has responded to Silver Spring homes and businesses for decades, from the brick rowhouses along Sligo Avenue in ZIP 20910 to the commercial corridors near Georgia Avenue and Colesville Road.

Call (866) 561-3358 for a free estimate or immediate service.
Silver Spring is not a cookie-cutter suburb. The southern ZIPs hold Montgomery County’s densest concentration of pre- and post-WWII housing stock, while the northern reaches blend 1960s ranches with newer construction. That age diversity means an HVAC company working here must understand gravity hot-water systems, steam-to-forced-air conversions, and the specific challenges of retrofitting ductwork into homes that were never designed for it. We have done this work in Silver Spring since 2018.
Why Fireside Heating & Air Co. Is Silver Spring’s Preferred Emergency & Commercial HVAC Company
Over 8 years, we have built our reputation in Montgomery County one job at a time. Silver Spring homeowners know our trucks, and they know our technicians put on shoe covers without being asked. Glen Hartman founded this company in 1984 on a simple standard: treat every home like your mother’s. That has not changed.
Our response time to Silver Spring is typically under two hours for emergency calls placed during business hours, and we maintain overnight and weekend crews for true heating emergencies when temperatures drop into the teens, as they regularly do here on the northern fringe of the DC urban heat island. We know the difference between a 20910 rowhouse with original steam radiators and a 20904 split-level with a 1990s furnace swap, and we size our trucks accordingly.
We are not a franchise operation sending trainees with a script. Our technicians are trained journeymen, background-checked and uniformed, who carry parts for Carrier, Trane, Lennox, and American Standard on every truck serving Silver Spring. The 90-Day Done Right Promise backs every repair and installation in writing: if it is not done right, we make it right, with no paperwork and no arguing.
Our Emergency & Commercial HVAC Services in Silver Spring
24/7 Emergency HVAC
A dead furnace in a 1950s Silver Spring brick rowhouse is not just uncomfortable; it can freeze pipes and force a family into a hotel. Our phones are answered by a live person at 2 a.m., every night of the year. We carry common ignition modules, blower motors, and heat exchanger parts for the nine major brands we service, and our Silver Spring emergency crew knows which downtown streets have limited parking and which garden apartment complexes require vendor badges. Most no-heat and no-cool emergencies are resolved in a single visit.

Commercial HVAC
Silver Spring’s commercial base runs from small retail along Fenton Street to mid-rise office buildings and medical suites near the Silver Spring Metro. We service packaged rooftop units, split systems, and VRF installations for property managers and business owners who cannot afford downtime. Our commercial technicians understand Montgomery County’s enforced IECC requirements and will not spec equipment that fails inspection. We offer scheduled maintenance agreements to catch compressor wear and refrigerant leaks before they shut your building down on the hottest day of August.

Rooftop Unit Service
Rooftop units in Silver Spring take a beating. The DC urban heat island effect pushes ambient temperatures higher here than in Germantown or Gaithersburg, and RTU compressors work harder for longer hours. We perform full diagnostic checks on economizers, exhaust fans, and refrigeration circuits, and we stock replacement compressors and control boards for Carrier and Trane units common in Silver Spring’s commercial inventory. When a rooftop unit fails, we assess repair versus replacement with honest numbers, not a sales pitch.

Chiller Service
Commercial buildings with chilled-water systems in Silver Spring rely on consistent performance through humid mid-Atlantic summers. We service scroll, screw, and centrifugal chillers, addressing common failure points including refrigerant leaks, tube scaling from WSSC’s moderately hard water supply, and control system drift. Our chiller work includes full load testing and seasonal startup protocols to prevent the catastrophic failures that strand tenants.

HVAC Inspection
Before you buy a 1940s-1960s home in Silver Spring’s inner ZIPs, get an HVAC inspection from someone who knows what original steam and gravity systems look like when they are failing. We document remaining service life, estimate conversion costs to forced air or mini-duct systems, and flag the common shortcuts that fail Montgomery County inspection. An inspection from Fireside gives you real numbers for negotiation, not vague warnings.

Annual Maintenance
Our $89 Seasonal Tune-Up includes combustion analysis, refrigerant pressure check, electrical connection torque, and filter assessment. For Silver Spring homes with original equipment still running, maintenance often reveals failing heat exchangers or cracked boiler sections before they become carbon monoxide hazards or mid-winter emergencies.

Common Emergency & Commercial HVAC Problems We See in Silver Spring Homes
- Original steam or gravity hot-water systems fail catastrophically in older rowhomes. We see this most in ZIP 20910 and 20901, where 1940s-1960s brick rowhouses and garden apartments still run original boilers. When the cast-iron section cracks or the wet-base corrodes through, there is no patching it. The home has no heat, and the only permanent solution is a full conversion to forced air, high-velocity mini-ducts, or a modern hydronic retrofit.
- Oversized single-stage oil furnaces short-cycle when swapped with modern equipment. Many Silver Spring Cape Cods and split-levels in 20904 and 20906 still have ductwork sized for the original oil furnace. Drop in a new gas furnace or heat pump without a fresh Manual J load calculation, and the system short-cycles, fails to dehumidify, and flunks Montgomery County’s IECC inspection. We have fixed this mistake after other contractors made it.
- WSSC hard water destroys humidifiers and condensate neutralizers within two heating seasons. Silver Spring’s water runs moderately hard, and calcium scale builds fast on evaporator pads and neutralizer media. Technicians who install these components without water treatment or self-cleaning designs are booking their own repeat calls. We account for this on every installation.
- Heat pumps undersized for Silver Spring’s winter lows. The urban heat island helps in summer but does not save you in January when temperatures hit the teens. Heat pumps without properly sized backup heat strips or dual-fuel gas backup leave homeowners cold and calling for emergency service. We size for the design temperature, not the average.

FAQs - Emergency & Commercial HVAC in Silver Spring
Yes, and we do it regularly in ZIP 20910 and 20901. Most conversions use a high-velocity small-duct system or a multi-zone mini-split, running supply lines through closets and ceiling chases rather than tearing out plaster walls. We responded to a no-heat call in a 1950s brick rowhouse on Sligo Avenue in ZIP 20910. The original steam boiler had cracked beyond repair, and the home had no existing ductwork. Our crew installed a high-velocity small-duct Carrier system with a gas furnace and heat pump, running fresh supply lines through closets and ceiling chases - a conversion common in this vintage stock. Costs typically align with our AC installation range of $3,500-$7,500 depending on zones and equipment. Call (866) 561-3358 for a free in-home assessment.
Commercial emergency calls in Silver Spring are typically dispatched within two hours during business hours, and our after-hours line connects you to a live person who can mobilize a crew overnight. We stock replacement compressors and control boards for common Carrier and Trane RTU models. Call (866) 561-3358 now for immediate dispatch.
The ductwork was likely sized for an oversized single-stage oil furnace, and the new equipment was installed without a Manual J load calculation. Modern variable-speed or two-stage systems need properly sized ducts to run their full cycles; restricted airflow causes rapid on-off operation, poor dehumidification, and premature compressor failure. This also fails Montgomery County’s enforced IECC inspection. We correct this by testing static pressure and resizing or adding return pathways. Call (866) 561-3358 for a diagnostic - estimates are free.
For many Silver Spring homes, yes. Winter lows here regularly reach the teens, and a standard heat pump without properly sized backup heat strips or a gas furnace backup will struggle on the coldest nights. Dual-fuel systems automatically switch to gas when temperatures drop below the heat pump’s efficient operating range, which in Silver Spring’s climate is typically around 35°F. We size every system for the local design temperature, not regional averages. Call (866) 561-3358 to discuss whether dual-fuel makes sense for your home.
Almost certainly. WSSC water in Silver Spring runs moderately hard, and calcium scale builds rapidly on evaporator pads and in condensate neutralizers. Technicians who install these components without addressing water quality or selecting self-cleaning designs find themselves on repeat service calls within two heating seasons - a failure pattern veterans here know well and new entrants consistently underestimate. We specify water treatment or scale-resistant designs on every humidifier installation in Silver Spring. Call (866) 561-3358 and we will diagnose the root cause and fix it permanently.
