A furnace that won't light or keeps shutting off needs real diagnosis, not another reset. Every visit includes a carbon monoxide safety check, standard, not an upsell.

Furnace failures in Janesville cluster around a handful of parts — ignitors, flame sensors, gas valves, heat exchangers. Each gets tested with a multimeter and combustion analyzer, not replaced on a hunch, not parts-cannon guessing.
What doesn't change from visit to visit.
Every repair includes a CO check, not optional.
No-heat calls in Janesville get priority routing over routine work during cold snaps when it's cold.
Ignitor or heat exchanger, the price is quoted and approved before work begins.
Our techs are trained equally on gas furnaces and electric heat strips, no exceptions.
Six repairs that cover most of our winter calls.
Cracked ignitors and carbon-fouled sensors cause a large share of no-heat calls, usually a same-visit fix.
Gas valve testing confirms the fault before we recommend replacing it.
We inspect carefully with proper equipment rather than assuming based on age.
Short-cycling or mid-cycle shutdowns often trace to the limit switch or a struggling blower before condemning the control board.
We still service older standing-pilot systems that newer ignition doesn't have.
Zero response from the furnace can mean a wiring fault, not a furnace failure to avoid overcharging for parts you don't need.

What happens from your call to heat restored.
Describe the symptom and we route the nearest tech and we'll get someone moving.
A stocked truck arrives ready to diagnose and often repair same visit.
Combustion analysis happens before any repair is quoted, then a flat-rate quote.
Most repairs finish same visit, with a final CO check before we leave, backed by warranty.
Recent reviews from winter heating calls.
Pilot light kept going out on our older furnace every few days. Tech identified a failing thermocouple that two other companies had overlooked.
