Why is the furnace not working?

A no-heat symptom does not identify the failed part by itself. These common patterns help organize the visit; the technician verifies the cause at the equipment.

  • The pilot light or burner will not stay onPilot, ignition, burner, and safety checks

    A pilot that lights and then goes out can involve the pilot assembly, flame-sensing components, gas delivery, venting, or a safety control. The furnace should be inspected rather than repeatedly reset.

    We separate a pilot or ignition problem from thermostat, gas-supply, venting, and safety-control issues before recommending a repair.

    • Pilot or electronic ignition condition
    • Flame sensing and burner operation
    • Limit, pressure, and other safety controls
  • The furnace will not startThermostat, power, and start sequence

    A blank thermostat, tripped disconnect, failed igniter, open safety switch, or control problem can all present as a furnace that does not run.

    The technician follows the furnace start sequence so the recommendation addresses the failed step instead of guessing from the symptom.

    • Thermostat call and settings
    • Power, controls, and safeties
    • Ignition and burner sequence
  • The home is not warming evenlyBlower, airflow, and equipment condition

    Uneven heat can involve the blower, filter, duct airflow, controls, or the furnace itself—not only the thermostat.

    We check how the furnace produces and distributes heat, including the blower and airflow conditions that affect comfort and equipment operation.

    • Blower operation
    • Filter and airflow restrictions
    • Temperature rise and equipment condition

What to expect during furnace repair

The visit follows one clear path, from the first conversation through testing and a review of the finished work.

  1. Tell us what is happening

    Share the symptoms, address, and timing so the team can prepare for the furnace repair request.

  2. We evaluate the system

    We check the affected equipment and controls and look for the underlying cause.

  3. You review the options

    We explain what we found and the price before you approve any work.

  4. We complete and verify it

    We finish the work, test it, and go over it with you before the visit ends.

What changes the work and the price?

The exact price comes after the system is evaluated. These are the factors that most often change the work required.

  • The verified cause

    Similar symptoms can come from different failures, so diagnosis comes before a recommendation.

  • Condition and compatibility

    Age, material, equipment condition, and compatibility determine whether repair is practical.

  • Access and site conditions

    Location, clearances, finishes, and the route to the work area affect labor and restoration.

  • The approved option

    Repair, component replacement, and broader upgrades involve different amounts of work. You choose before work begins.

Our work is backed by a lifetime workmanship warranty for the typical lifespan of the installation. Terms apply.

The right next step depends on what we find

Condition, access, safety, compatibility, and the needs of the home determine which approach makes sense.

  • Repair the existing system

    Correct a serviceable component or connection when the overall system remains sound.

    • Thermostat and controls
    • Ignition, burners, and safety switches

  • Replace the failed component

    Install a compatible replacement when a component is worn, damaged, or unsuitable.

    • What the work involves and what fits
    • Expected service life
    • Access and disruption

  • Upgrade the system

    Plan a broader improvement when capacity, condition, or household needs call for it.

    • The work you approve
    • System testing
    • Care and next steps

Furnace pilot-light and repair questions, answered

Direct answers to the no-heat questions homeowners ask most often. We confirm what applies to the specific furnace.

Call 978-293-5770

  • Why does my furnace pilot light go out when I turn the furnace on?

    The cause can be in the pilot assembly, flame-sensing components, gas delivery, venting, or a safety control. Because several different faults can produce the same symptom, repeated relighting is not a diagnosis; the furnace should be checked if the pilot will not remain lit.

  • Can I relight a furnace pilot light myself?

    Only follow the exact lighting instructions on the furnace or in its manufacturer documentation. Do not attempt to relight it if you smell gas, the instructions are missing, or the pilot repeatedly goes out. Leave the area and contact the gas utility or emergency services if a gas leak may be present.

  • What is checked when a furnace pilot will not light?

    A service visit may include the thermostat call, power and controls, gas supply at the appliance, pilot or igniter, flame sensing, burner operation, venting, and safety switches. The specific checks depend on the furnace design and the symptom observed.

  • Will I know the price before furnace repair begins?

    Yes. After we diagnose the problem, we explain your repair options and the price before you approve any work.

  • Does Spencer provide furnace repair outside Peabody?

    Spencer serves homeowners across the North Shore. Availability for a specific address is confirmed when the request is reviewed.
