Thermostat, power, gas supply, ignition and control-board testing to find why the furnace will not fire.
Furnaces that click, light and shut off are often a dirty flame sensor or a failing hot-surface igniter.
Limit switches, pressure switches and inducer motors checked in order.
Overheating from restricted airflow, a dirty filter or an oversized furnace.
Banging, squealing or a burning smell checked before the next cold night.
Venting, heat-exchanger visual check and carbon monoxide concerns raised in plain language.
December and January nights in Yountville average near 38°F, so a failed furnace is felt fast. Most problems trace to a few parts.
Dirty flame sensors and worn hot-surface igniters are the most common causes of a furnace that starts and shuts off.
Clogged filters, weak blower motors and failed capacitors cause overheating and lockouts.
Venting, gas connections and the heat exchanger are inspected during the visit.
