What HVAC problems are most common in Foster City?
The issues we see most in Foster City: Salt air corrosion, Humidity control, and Aging original systems. Foster City's bay location provides mild, consistent temperatures. Fog and wind can be factors. The water moderates temperature extremes. Humidity from the lagoons and bay can be noticeable.
Why won't my AC or heater turn on?
A system that runs but won't cool is often a failed capacitor, low refrigerant, a dirty coil, or a tripped safety switch, while no heat is commonly a bad igniter, flame sensor, clogged filter, or thermostat fault. A proper visit checks refrigerant charge, electrical components, and airflow before quoting any repair.
