What HVAC problems are most common in San Lorenzo?
The issues we see most in San Lorenzo: Aging post-war tract home systems, Original ductwork deterioration, and R-22 phase-out concerns. San Lorenzo experiences typical East Bay flatland weather: warm summers and mild winters. The low-lying position can trap heat. Both heating and cooling are useful for comfort.
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.
