Complete furnace diagnosis with safety assessment included on every gas furnace service. Specific fault identified and explained. Upfront pricing. Safety and performance both verified before we leave. Every repair guaranteed.
You woke up to a cold house in Norwich. The thermostat is set where it always is but the furnace is not running, or it is running without producing heat, or it started and shut itself off after a few seconds in Norwich, NY. In cold weather, a furnace failure is not something you work around until a convenient repair date opens up in Norwich. It is an urgent situation that affects every person in the home from the moment the heat stops working in Norwich, NY. Indoor temperatures drop progressively as the home loses heat to the cold exterior in Norwich. Pipes in unheated spaces approach freezing as indoor temperatures fall in Norwich, NY.
For gas furnaces specifically, the urgency extends beyond comfort and pipe protection in Norwich. A gas furnace is a combustion appliance, and specific failure conditions create safety risks that make continued operation without assessment the wrong choice in Norwich, NY. A cracked heat exchanger allows combustion gases including carbon monoxide to mix with the circulated air and be distributed to every room in the home in Norwich. A rotten egg or sulfur odor indicating a gas leak warrants shutting the system off and calling for service immediately rather than continuing to operate it in Norwich, NY. These are not performance issues. They are safety issues in Norwich.

Every MBM gas furnace service includes a safety assessment covering visual inspection of the heat exchanger for cracks, assessment of gas connections, gas pressure measurement at the furnace inlet, venting system assessment, and carbon monoxide measurement in the circulated air where indicated in Norwich. The safety assessment is a standard component of every gas furnace service. Not an optional add-on. The safety assessment is a standard component of every gas furnace service in Norwich, NY. Not an optional add-on in Norwich.
Failed igniter. Failed flame sensor preventing the gas valve from opening. Tripped high-limit switch from a previous overheating event. Failed control board. Thermostat wiring fault or failed thermostat. Gas supply issue in Norwich, NY. MBM diagnoses no-heat situations systematically beginning with the most common and correctable causes in Norwich.
A furnace that initiates the startup sequence and shuts off within seconds almost always has a flame sensor problem in Norwich. The furnace ignites the burners, the flame sensor fails to confirm the flame within the safety window, and the control board shuts the gas valve as a safety measure in Norwich, NY. Flame sensor cleaning or replacement addresses this in most cases in Norwich.
Failed igniter running the blower without lighting the burners. Gas valve not opening despite the igniter firing. Burner ports contaminated enough that the flame is not establishing correctly in Norwich, NY. MBM diagnoses the specific combustion fault before recommending any repair in Norwich.
Contaminated heat exchanger reducing thermal efficiency. Dirty burners producing incomplete combustion and reduced heat output. Duct system leakage delivering conditioned air to unconditioned spaces. Or a system that is undersized for the home's actual heat loss in cold weather in Norwich.
The most common cause is the high-limit switch tripping because restricted airflow is causing the heat exchanger to overheat in Norwich, NY. A dirty air filter severely restricting return airflow is the most common cause of limit switch tripping in Norwich.
A persistent burning smell that does not clear, a burning plastic smell indicating an electrical fault, or a rotten egg or sulfur smell indicating a gas leak are situations requiring the furnace to be shut off and MBM called immediately in Norwich. Do not operate the furnace with any persistent or concerning smell until it has been assessed in Norwich, NY.
A banging or booming sound at startup indicates delayed ignition from dirty burners in Norwich, NY. A squealing sound from the air handler indicates a failing blower motor bearing in Norwich. A rattling sound during operation may indicate a loose heat exchanger component in Norwich, NY.
Carbon monoxide is the combustion byproduct that presents the most serious immediate safety risk from a faulty gas furnace in Norwich, NY. It is colorless and odorless in Norwich. A correctly operating gas furnace with an intact heat exchanger exhausts all combustion gases to the outside in Norwich, NY. A furnace with a cracked heat exchanger allows combustion gases to enter the circulated air in Norwich.
A confirmed cracked heat exchanger is not a condition that can be managed carefully while a convenient repair window opens up in Norwich. A cracked heat exchanger allows combustion gases including carbon monoxide to enter the circulated air with every heating cycle in Norwich, NY. MBM's recommendation for a confirmed cracked heat exchanger is to cease operation of the furnace until the heat exchanger or furnace is replaced in Norwich.
A rotten egg or sulfur smell near the furnace or gas lines indicates a gas leak in Norwich. The correct response is to not operate any electrical switches, evacuate the home, and call the gas utility from outside in Norwich, NY. Do not re-enter until the gas utility has confirmed the situation is safe in Norwich.
The flame sensor confirms a flame is present before the control board allows the gas valve to stay open in Norwich, NY. Oxidation on the sensor rod reduces its electrical conductivity over time, causing a signal too weak to satisfy the control board in Norwich. The control board shuts the gas valve as a safety measure, producing the furnace that starts and shuts off within seconds symptom in Norwich, NY.
The hot surface igniter is a fragile ceramic component that glows red-hot to ignite the gas burners in Norwich. Igniters become brittle over time from thermal cycling and crack or fail from physical shock in Norwich, NY. A failed igniter produces no glow and no ignition in Norwich.
The heat exchanger separates the combustion gases from the circulated air in Norwich, NY. A cracked heat exchanger allows combustion gases including carbon monoxide to cross into the circulated air and be distributed throughout the home by the blower in Norwich. A confirmed cracked heat exchanger means the furnace should not be operated until the heat exchanger or furnace is replaced in Norwich, NY.
A failed blower motor produces no airflow despite the combustion system operating correctly, causing the heat exchanger to overheat and the high-limit switch to trip in Norwich. A failing blower capacitor causes the motor to struggle to start or fail to start entirely in Norwich, NY.
The control board manages ignition sequencing, blower timing, safety switch monitoring, and fault code storage in Norwich, NY. A failed control board can produce a wide range of symptoms depending on which function it was managing in Norwich.
The high-limit switch shuts the furnace off if the heat exchanger temperature exceeds the safe maximum in Norwich. It trips consistently when the heat exchanger is reaching unsafe temperatures, almost always from restricted airflow in Norwich, NY. A dirty air filter is the most common cause in Norwich.
