Ventura County homes deal with a familiar mix of coastal air, seasonal winds, and everyday household dust. Add pets, nearby landscaping, and the occasional remodel, and it is easy for debris to build up in places you rarely see. One of the most important hidden spots is your Sub-Zero’s condenser area. When condenser coils and intake vents get clogged with dust and lint, your refrigerator cannot release heat efficiently. The unit may still feel cold inside, but it starts running longer, running hotter, and working harder than it should. Over time, that extra strain can lead to bigger failures. Many calls for sub zero fridge repair in ventura county begin with a simple root cause: restricted airflow.
