A furnace that won't ignite, short-cycles, or keeps tripping its limit switch needs more than a reset in Mount Prospect winters. A CO check happens on every call, standard, not an upsell.
Furnace failures in Mount Prospect cluster around a handful of parts — ignitors, flame sensors, gas valves, heat exchangers. We test with real equipment, not parts-cannon guessing.
What doesn't change from visit to visit.
Every repair includes a CO check, not optional.
We bump no-heat calls ahead of routine visits when it's cold.
Ignitor or heat exchanger, the price is quoted and approved before work begins.
Both fuel types get the same trained tech, 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.
We test actual response and pressure output rather than replacing an expensive part on a hunch 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.

Tell us what the furnace is doing and we'll get someone moving.
Truck arrives stocked with common ignitor, flame sensor, and control parts ready to diagnose and often repair same visit.
Safety and diagnostic checks come first, then a flat-rate quote.
Most repairs finish same visit, with a final CO check before we leave, backed by warranty.
