On a cold day, a furnace that will not start can quickly become a problem for the whole household. ARP Heat And Air provides furnace repair in Moore, including residential areas around Veterans Memorial Park.
The issue: The thermostat calls for heat, but the furnace will not light
If the thermostat is set to heat and the house remains cold, the cause may involve the thermostat, the power supply, the ignition system, a control, or another component. A furnace that will not light should be diagnosed rather than restarted over and over.
Our team asks what the homeowner has observed and checks the equipment’s startup sequence. Those details help us determine whether the furnace is responding to the thermostat and where the heating cycle is stopping.
Finding the cause and completing the repair
One possible cause of a no-heat call is a failed igniter. If our testing shows that the igniter needs replacement, we explain the finding and the recommended work. Once the homeowner approves, we replace the part and check the furnace through a heating cycle.
Not every furnace that fails to start needs an igniter. Our repair recommendation depends on the actual diagnosis, and we check operation after completing the work.
Before your appointment
Check that the thermostat is set to heat and above the current room temperature. If the filter is easily accessible, check whether it is visibly dirty. Leave electrical, gas, and internal furnace work to a qualified technician.
If you smell gas, leave immediately without operating switches or devices, then call 911 and your gas utility from a safe location. If a carbon monoxide alarm sounds, go outside to fresh air and call 911; do not reenter until emergency responders say it is safe.
