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.
Most Milpitas single-family homes still heat with a gas furnace in the attic, garage or a hall closet. Winter nights here drop into the low 40s, so a failed furnace is felt quickly.
Hot surface igniters, flame sensors, inducer motors and pressure switches. HAXX carries frequently needed parts.
Venting, heat exchanger and carbon monoxide checks are part of every furnace call.
Bay Area Air District rules limit sales of new gas furnaces starting in 2029. Repairing an existing furnace is not affected.
