Furnace not working in San Marcos? No heat on a cold morning is one of the most common calls we take, and one of the fastest to fix. Our technicians reach San Marcos homes the same day, find why the furnace will not turn on and restore heat, usually in a single visit.
Call (855) 459-5498A furnace that will not run is usually stopped by a safety control doing its job: a limit switch tripped by restricted airflow, a pressure switch that cannot prove the inducer is running, a flame sensor too dirty to confirm ignition, or a door switch not fully engaged. Sometimes it is simpler still, such as a dead thermostat battery or a tripped breaker. We check the simple things first and only replace what is actually failed.

Our restaurant rooftop unit died on a Friday lunch. They came out that afternoon and had us cooling again before the dinner rush. Lifesavers for a business in San Marcos.
Robert M., San MarcosHad them out for an AC tune-up before summer. Thorough inspection, cleaned the coils, and they found a weak capacitor that would have failed in July. Smart move.
James W., San MarcosInstalled a ductless mini split in our garage conversion. Neat work, quiet unit, and they walked us through the remote and app. Very happy.
Patricia H., San MarcosMake sure the thermostat is on heat and set above room temperature, the furnace breaker is on, the furnace switch on the unit is on, the filter is not clogged and the furnace door is fully closed. If it still will not run, call us.
The burners are not lighting or are shutting off early. A dirty flame sensor, bad igniter or tripped limit switch is the usual cause.
