What are the most common HVAC problems here?

Most calls are either no-cooling or no-heat. No-cooling is often a failed capacitor, low refrigerant, or a tripped safety switch; no-heat usually traces to ignition, a dirty flame sensor, or a thermostat fault. Local conditions matter too—Mediterranean with coastal fog influence—so a proper visit always checks refrigerant charge, electrical connections, and airflow before we recommend any repair.
