Gas Smell or a Carbon Monoxide Alarm? Leave First
If you smell gas, suspect a gas leak or hear a carbon monoxide alarm, get everyone outside immediately. Call 911 from a safe location. For a suspected gas leak, also contact your gas utility’s emergency line. Do not operate switches, use a phone inside, light a flame or try to restart the furnace. Stay outside until emergency responders say it is safe to return.

Furnace Types We Repair
The type of fuel your furnace uses affects how it makes heat, and so it affects what our technician checks first. Tell us whether you have a gas, oil or electric furnace when you call. That helps us prepare for the right inspection.
Gas Furnace Repair
Does your gas furnace click, try to light and then shut off? Or run for a few minutes and stop? One symptom can have several possible causes. It could be a dirty flame sensor, which tells the furnace the burner has lit. It could be a worn igniter, a gas valve problem or a blocked vent that trips a safety control. Our technicians inspect the ignition sequence, safety controls and venting to find the root cause before we recommend a repair. If your gas furnace isn’t heating your Northern Virginia or Maryland home, schedule an inspection. If you ever smell gas, leave the home first and call 911 from a safe place.
Oil Furnace Repair
Is your oil furnace running without heating, giving off smoke, or leaving soot around the unit? The cause could be in the fuel supply, such as a clogged filter or nozzle or a worn fuel pump. It could also be in the burner controls that start the flame and confirm it’s burning. Before you call, check that your tank has oil and whether the burner’s reset button has tripped. Avoid pressing the reset button more than once. If the furnace still won’t run, our technicians can inspect the system and explain the repair options.
Electric Furnace Repair
Is your electric furnace blowing lukewarm air or tripping its breaker? Electric furnaces have no flame. They make heat with electric heating elements that switch on in stages. Weak heat may come from a failed element, the part that switches the elements on, a limit switch or an airflow problem. First, check the thermostat setting, the air filter and the furnace breaker. If the problem continues, schedule an inspection. Our technicians will find the underlying cause before recommending a repair.
Emergency Furnace Repair
Some heating problems shouldn’t wait, like a complete loss of heat in freezing weather, a burning smell or a furnace that keeps shutting down. We provide emergency furnace service across Northern Virginia and Maryland 24 Hours, 7 Days a Week, 365 Days a Year. When you call, have your ZIP code, furnace fuel type and a short description of the problem ready. After we diagnose the system, we’ll explain the proposed repair and its cost before any work begins. Call Virginia: 703-457-9028 or Maryland: 301-686-7129. If you smell gas or your carbon monoxide alarm sounds, get everyone outside and call 911 first.
Tell Us Which Furnace Problem You Are Seeing
The furnace produces no heat
Tell AVS whether the thermostat is blank, whether you hear the furnace start and whether air comes from the vents. A furnace no-heat call can involve controls, ignition, power or another equipment fault; the symptoms help guide the inspection.
The furnace is blowing cold air
Air movement does not necessarily mean the burners are operating. The thermostat’s fan setting, an ignition problem or a system shutdown may be involved. Let us know whether the air stays cold or becomes cold after the furnace has been running.
The furnace starts, then quickly shuts off
Furnace short cycling can leave rooms cold even when the equipment starts repeatedly. Report the pattern and any visible error code without removing access panels or bypassing a safety switch.
The furnace clicks or tries to ignite without staying on
A furnace ignition problem needs inspection of the relevant ignition and safety controls. Repeatedly resetting the equipment does not establish why it is failing to run.
Airflow is weak, rooms heat unevenly or noises have changed
A blower issue or restricted airflow may affect heat delivery. Note which rooms are cold and whether a new rattling, scraping or banging sound occurs at startup or during operation. Persistent unusual odors also warrant attention; use the emergency guidance above for a gas odor or CO alarm.
What a Furnace Inspection May Include
Your furnace’s fuel type, design and symptoms determine the appropriate checks. A diagnosis may involve the thermostat, ignition system, flame sensor, blower motor, control board and airflow. For fuel-burning equipment, the condition of the heat exchanger, venting and combustion operation may also be relevant.
Ask the technician to distinguish a failed component from the condition causing it to fail. An airflow restriction, for example, deserves attention alongside a shutdown that it may be triggering.
If a heat-exchanger or combustion-safety concern is identified, ask to see the findings and have the recommended next step explained. Safety concerns should be resolved before the equipment returns to service.
What Affects Furnace Repair Cost?
Furnace repair cost in Northern Virginia and Maryland depends on the fault and the equipment. An igniter or flame-sensor issue has a different scope from a blower motor replacement, control board repair or heat-exchanger evaluation.
The estimate can also be affected by equipment access, part availability, related damage and applicable parts coverage. Ask whether the diagnostic fee is separate and what the quoted repair price covers.
If the technician recommends more than one repair, ask which work is needed to restore safe operation and which items address other concerns. That helps you understand the decision without relying on a generic online price range.

Furnace Repair or Replacement: What Should Guide the Decision?
Repair may be a practical choice for a serviceable furnace with an isolated, repairable fault. Compare replacement when there is a significant safety concern, repeated breakdowns, a major repair or continuing difficulty heating the home.
Equipment age provides context, but it does not replace an inspection. Review condition, repair history, coverage, parts availability and the total work needed. When replacement is being considered, ask how the proposed system addresses your home’s heating and airflow needs.
You can explore furnace installation and replacement after the repair findings are clear.
