Common Furnace Problems in San Marcos
With San Marcos winters dropping to 40°F, a struggling furnace needs prompt attention. These are the most common heating problems technicians see in San Marcos and San Diego County.
Furnace Not Heating
When your furnace won't heat in San Marcos's Mediterranean climate, pros start with thermostat settings, power supply, ignition components, and safety switch status.
Short Cycling
Short cycling in San Marcos's cold winters is a warning sign. Dirty filters causing overheating, failing flame sensors, and limit switch problems are the most common causes.

Strange Noises
Rattling, booming, or squealing can indicate loose parts, motor/belt issues, ignition problems, or duct expansion.
High Heating Bills
Rising heating costs in San Marcos despite regular use often point to dirty burners, restricted airflow, aging components, or duct leakage reducing system efficiency.
