Check your fuel supply — oil tank level or gas service
Igniter failure is one of the most common causes of a furnace not starting
Clogged fuel filter prevents ignition on oil systems
No-heat scheduling depends on weather, demand, location, and access
Frequently Asked Questions
Why won't my furnace turn on?
Common causes include a faulty igniter, tripped high-limit switch, clogged fuel filter, failed draft inducer motor, or thermostat issue. We diagnose the specific cause and repair it in one visit whenever possible.
My furnace tries to start but won't ignite. What's wrong?
Usually a failed igniter (hot surface or spark type), dirty burner, or fuel delivery issue. Igniter replacement is one of the most common furnace repairs we do.
Can I restart my furnace myself?
You can reset the furnace by pressing the reset button on the burner assembly — but do this only once. Multiple resets without professional diagnosis can create a fuel buildup safety hazard. If one reset doesn't fix it, call us.
How quickly can RG Mechanical respond to a no-heat furnace call?
Availability depends on weather, demand, location, access, and parts. Call promptly for current scheduling and safe interim guidance; no specific response time is guaranteed.
