Complete system failure, dangerous CO readings, extreme cold with no heat -- these can't wait until morning. Our emergency technicians are dispatched immediately, any hour, any day in Washington and across Washington, DC.
Typical emergency response: under 2 hours. No appointment needed.
Leave the building immediately, do not operate any switches or appliances, and call 911 from outside. Once emergency services have cleared the space, call us at +1-866-805-8548 for immediate HVAC system assessment and repair.
HVAC systems fail at night. They fail on the coldest weekend of the year. They fail during heat waves when every HVAC company in Washington is already booked solid. That's not a coincidence -- systems fail under strain, and extreme weather is exactly when they're working hardest. All Year HVAC exists to be the company that actually picks up the phone and shows up when those calls come in.
Our emergency dispatch is not an answering service that takes a message for the morning crew. When you call +1-866-805-8548 at 2am with no heat and temperatures dropping, you reach a live dispatcher who immediately checks technician availability and routes the closest available emergency tech to your location. Most emergency calls in Washington result in a technician on site within two hours. We maintain emergency-ready staffing year-round, with additional coverage during peak seasons when demand spikes.
The hazard profile of an HVAC emergency varies significantly by the type of failure. A complete cooling loss during a heat advisory creates dangerous conditions for elderly residents and young children within hours. A complete heat loss during a winter cold snap in Washington, DC can push indoor temperatures below safe levels overnight and can result in frozen pipes that cause their own cascade of damage. A gas furnace that locks out on safety may be indicating a cracked heat exchanger and potential carbon monoxide intrusion -- that's a scenario that requires immediate response and cannot wait for a next-day service window.
Our emergency technicians carry the same diagnostic equipment and parts inventory as our daytime crews. They're not sent out with a flashlight and a voltmeter to assess the situation and schedule a real repair for the morning. They come equipped to complete the repair on the spot for the vast majority of emergency failures -- a capacitor, a control board, a failed igniter, a refrigerant undercharge. When the repair requires parts not on the truck, we tell you immediately and either source the part for overnight delivery or arrange a temporary solution to stabilize your home until the repair can be completed the following morning.
Every scenario below is a genuine emergency. We dispatch for all of them, day or night, without extra fees for evening or weekend calls.
A total heat loss during a winter cold snap in Washington, DC is not an inconvenience -- it's a health emergency. Indoor temperatures can drop to dangerous levels within hours, and water pipes in uninsulated spaces can freeze and burst. Our emergency technicians arrive with diagnostic equipment and a full parts complement, ready to restore heat in a single visit for the majority of furnace failure scenarios including igniter failure, gas valve faults, and control board lockouts.
A CO alarm triggered by a furnace or boiler is a life-safety event. Even when the alarm seems intermittent or low-level, it demands immediate investigation. Our emergency technicians carry calibrated CO detectors and combustion analyzers to verify whether combustion gases are entering the living space, identify the source, and determine whether the system can be safely operated. We do not clear systems for operation without confirming the cause of the CO event and addressing it.
When outdoor temperatures peak and your AC fails completely, indoor temperatures in a closed-up home can become dangerous within a few hours for vulnerable occupants. We treat complete cooling loss during heat advisory conditions as the same priority as heating failure in winter. Our emergency cooling response addresses compressor failures, electrical faults, refrigerant loss, and control failures for central air systems and ductless mini-splits.
A gas smell in or near your HVAC system is always treated as an emergency. If you can smell gas, evacuate and call your gas utility's emergency line and 911 before calling us. Once the utility has confirmed the space is safe, our emergency technicians assess the HVAC system's gas supply connections, valves, heat exchanger, and burner assembly to determine the source and whether any components need replacement before the system can be safely returned to service.
A burning smell from an HVAC system or a breaker that trips every time the system tries to start indicates an electrical fault that should not be ignored or bypassed. Overheated motor windings, failing contactor coils, and short-circuited control boards can all present this way. Our emergency technicians isolate the faulted component, confirm there is no risk of fire, and either repair the fault or make the system safe until a full repair can be completed.
A blocked condensate drain or failed condensate pump can cause the secondary drain pan to overflow, resulting in ceiling water damage or interior water intrusion. While not a health-safety emergency in the same category as CO or extreme temperature loss, water damage escalates quickly and can result in mold growth within 24 to 48 hours. Our emergency response clears the drain blockage, checks the secondary pan integrity, and confirms the system is draining properly before leaving.
Our emergency line is answered by a real dispatcher, not an answering machine. You get a technician ETA within minutes of your call.
Emergency trucks carry expanded parts inventories for the most common after-hours failures. We repair, not just assess and schedule.
CO, gas, and electrical emergencies follow a defined safety protocol. Our technicians carry calibrated detection equipment and never clear an unsafe system.
You receive a written repair quote before work starts, regardless of the hour. We don't adjust prices based on the urgency of your situation.
From your call to a restored system -- here's exactly what to expect when you reach our emergency line.
A real person answers your call, gathers the situation details, and confirms whether this is a life-safety event requiring specific pre-arrival steps. You get a technician ETA before you hang up.
Our emergency tech arrives with diagnostic instruments, CO and combustion detection equipment, and a full emergency parts inventory. This is a repair dispatch, not a site assessment.
For CO, gas, or electrical scenarios, we complete a safety assessment before diagnostic work. You'll know immediately whether the space is safe and what specific hazard we identified.
After completing the repair, we run the system through a full operational cycle, verify it's performing correctly, and document the repair. You sleep in a comfortable, safe home.
"CO alarm went off at 11pm. Called All Year HVAC, they were at my door in 90 minutes. Found a hairline crack in the heat exchanger. They locked out the system, kept my family safe, and had a full repair crew back the next morning. Cannot thank them enough."
"Furnace died at 10pm on the coldest night of the year with two little kids in the house. Tech was here in under two hours, found a failed igniter, had one on the truck, and heat was back on by midnight. Absolute lifesavers."
"AC completely failed on a Saturday during a heat wave with my elderly mother visiting. All Year HVAC answered on the first ring, dispatched immediately, and had us cooling again by early afternoon. Professional, quick, and they didn't gouge on the emergency pricing."
