What St. Augustine's climate means for your Rational appliances
Every Rational lineup in St. Augustine lives through months of heat and damp air, and that leaves a mark over time. Salt air is hard on igniters, burner caps, and exposed steel, so corrosion tends to show up faster here than it does inland. These conditions can affect components differently, so the exact fault still requires diagnosis.
