A furnace that clicks but never lights, or one that lights and shuts off within seconds, usually points to a failing ignitor, a fouled flame sensor, or a safety switch doing exactly its job. Ignoring furnace won't ignite or keeps shutting off rarely makes the underlying issue cheaper to fix later.

Every job starts with a real diagnosis, not a guess — here's the full scope of what our Marshall, MO technicians handle.
We service central air, packaged units, and ductless mini-splits, and we size every new installation with an actual load calculation rather than matching the old unit's tonnage on a guess. Refrigerant leak detection uses electronic detectors and UV dye, not a repeated top-off that never addresses the actual leak. This is one of the most requested Hvac calls we get across Marshall, MO.
Every furnace call starts with a combustion analysis and carbon monoxide safety check before any repair recommendation, because a cracked heat exchanger is a safety issue first and a repair line item second. Heat pump-specific diagnostics cover the reversing valve and defrost cycle, components that a generalist unfamiliar with heat pumps can easily misdiagnose. Techs handling heating & furnace services carry the specific parts and tools this job calls for, not a generic kit.
Indoor air quality add-ons including whole-home filtration, UV air treatment, and humidity control are installed and serviced by the same Marshall, MO crews handling your core system.
