Frozen AC Coils in Palo Alto

Frozen AC coils are a common issue in Palo Alto, California, due to the region's slightly warmer climate and the prevalence of older HVAC systems in homes built between the 1950s and 1970s. These outdated systems often lack the efficiency and technology found in newer models, making them more susceptible to malfunctions. Factors such as insufficient airflow, low refrigerant levels, and dirty filters contribute to the problem, causing the evaporator coils to freeze. Homeowners should be vigilant for signs of reduced cooling performance or unusual noises from their AC units. If ice is visibly forming on the coils or if the system continues to underperform despite maintenance, it is crucial to call a professional to diagnose and resolve the issue before further damage occurs.
