A furnace that won't light or keeps shutting off needs real diagnosis, not another reset. A CO check happens on every call, standard, not an upsell.

A short list of components causes most Furnace Repair calls: ignitor, flame sensor, gas valve, heat exchanger. We test with real equipment, not parts-cannon guessing.
Safety and accuracy on every heating call.
Every repair includes a CO check, not optional.
We bump no-heat calls ahead of routine visits when it's cold.

Our techs are trained equally on gas furnaces and electric heat strips, no exceptions.

These two parts are behind most no-heat visits, usually a same-visit fix.

A cracked heat exchanger can leak combustion byproducts into the airflow — we inspect with a scope and analyzer rather than assuming based on age.
We test both before condemning the control board.
We still service older standing-pilot systems that newer ignition doesn't have.
We rule out wiring issues first to avoid overcharging for parts you don't need.

Feedback from completed furnace repairs.
Pilot light kept going out on our older furnace every few days. Tech identified a failing thermocouple that two other companies had overlooked.
