- Thermostat and controls
- Ignition, burners, and safety switches
- Blower, airflow, and equipment condition
Family-owned · Serving North Shore homes since 1981
If a furnace will not start, will not stay lit, or is not heating the home evenly, Spencer can diagnose the cause. We check the thermostat, ignition or pilot system, safety controls, burners, blower, and airflow, then explain the applicable repair options and pricing before approved work begins.

Start with what you are seeing
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.
What we check
We separate a pilot or ignition problem from thermostat, gas-supply, venting, and safety-control issues before recommending a repair.
One clear service visit
The visit follows one clear path from the first conversation through testing and review of the approved work.
Share the symptoms, address, and timing so the team can prepare for the furnace repair request.
The technician checks the affected equipment or piping and looks for the underlying cause.
We explain the findings, scope, and applicable pricing before you approve work.
The approved work is completed, tested, and reviewed with you before the visit ends.
Compare the next steps
Condition, access, safety, compatibility, and the needs of the home determine which approach makes sense.
Correct a serviceable component or connection when the overall system remains sound.
Install a compatible replacement when a component is worn, damaged, or unsuitable.
Plan a broader improvement when capacity, condition, or household needs call for it.
Cost and scope
The exact price comes after the system is evaluated. These are the factors that most often change the work required.
Similar symptoms can come from different failures, so diagnosis comes before a recommendation.
Age, material, equipment condition, and compatibility determine whether repair is practical.
Location, clearances, finishes, and the route to the work area affect labor and restoration.
Repair, component replacement, and broader upgrades have different scopes. You choose before work begins.
Common questions
Direct answers to the no-heat questions homeowners ask most often. A technician confirms what applies to the specific furnace.
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.
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.
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.
