When a furnace fails in cold weather, the cause is almost always one of a handful of known issues. Here are the problems our clients call us about most.
The most common cause is a cracked or burned-out igniter that can no longer reach the temperature needed to light the burner. Without ignition, the furnace runs through its startup sequence and shuts down without producing heat. We test the igniter first, confirm the control board is sending the correct signal, and replace the igniter with the right specification for your unit.
This almost always points to a dirty flame sensor coated in carbon residue, which prevents the sensor from confirming that the burner has lit. The furnace control board reads this as a failed ignition and shuts the gas valve within a few seconds as a safety measure. We clean or replace the flame sensor and test through a full start cycle to confirm stable burner operation.
When the furnace appears to be running but rooms stay cold, the blower motor may have failed, preventing warm air from circulating through the ductwork. A failed gas valve can also cause this if the burner never ignites despite the system going through its startup sequence. We check both the air delivery side and the combustion side before confirming the cause.
A carbon monoxide alarm triggered near the furnace should be taken seriously and can indicate a cracked heat exchanger allowing combustion gases to enter the living space. This is an immediate safety situation: evacuate the home and call for emergency service before re-entering. We perform a full safety inspection, confirm whether the heat exchanger is compromised, and explain the repair or replacement options before any further work proceeds.
A furnace that starts and shuts off repeatedly every few minutes is usually triggering the high-limit switch due to overheating, which is most often caused by a clogged air filter blocking airflow. Pressure switch failures from condensate line blockages and control board faults can also cause this pattern. We diagnose the specific trigger, clear any blockages, and test for complete cycle stability before finishing the call.
A gas odour near the furnace indicates a potential gas leak in the supply line, at the valve connection, or within the unit itself. This is an immediate safety situation that requires shutting off the gas supply and leaving the home before calling a professional. Our licensed gas technicians locate the source of the leak, repair the affected section, and test the system for proper gas containment before restoring heating.
A pressure switch fault usually means the inducer motor is not creating the negative pressure needed to confirm safe venting before the gas valve opens. Common causes are a blocked condensate drain, a cracked inducer housing, or a failed pressure switch diaphragm. We check the entire venting and drainage path before testing the switch itself to avoid replacing a component that is not the root cause.
A loud bang when the furnace fires up is almost always a delayed ignition issue, where gas builds up in the combustion chamber before finally igniting all at once. This puts stress on the heat exchanger and can cause it to crack over time if left unaddressed. We adjust the ignition timing, clean the burners, and confirm the system lights cleanly on every startup cycle.
When the thermostat appears unresponsive and the furnace is silent, the issue is often a tripped furnace breaker, a blown fuse on the control board, or a communication fault between the thermostat and the unit. These are quick to diagnose but easy to misread as a major failure. We test the full control circuit from the thermostat through to the furnace board to find where the signal stops.
Our furnace died at 11pm during a cold snap and Gas Services Edmonton had someone here within the hour. Turned out to be a failed igniter and it was fixed before midnight. Genuinely grateful for the fast response.
The technician found a cracked heat exchanger and explained the carbon monoxide risk clearly before recommending replacement instead of repair. No pressure, just an honest safety explanation. We felt genuinely looked after.
Our blower motor needed a specific part that wasn't on the truck so it took an extra day. Gas Services Edmonton left a portable heater with us in the meantime which really helped. Repair has worked perfectly since.
We were without heat for a few hours during a deep freeze and the technician talked us through shutting off the water supply while we waited. Nothing froze thanks to that advice. Repair itself was quick once he arrived.
I called worried about our furnace running rough but the dispatcher explained our situation could safely wait until the next business day and saved us the after-hours rate. Gas Services Edmonton earned our trust with that honesty.
The technician recognized our Carrier furnace's fault code immediately and had the exact igniter needed already on the truck. Whole repair took under an hour on an emergency call. Impressive knowledge of the specific brand.
