A furnace that won't ignite, short-cycles, or keeps tripping its limit switch needs more than a reset in Alton winters. A CO check happens on every call, standard, not an upsell.

The most common furnace failure points.
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.
