Frozen AC Coils in San Carlos

Frozen AC coils are a common issue in San Carlos, California, primarily due to the region's unique climate conditions. Homes situated in the hill areas can experience temperatures that are up to 10 degrees cooler than downtown, leading to inconsistent heating and cooling needs. When the air conditioning unit struggles to maintain the desired temperature, humidity can build up, causing the coils to freeze. This is particularly prevalent during warmer months when the system is overworked. Homeowners should be vigilant for signs of reduced airflow or unusual noises from the unit. If you notice these symptoms, it’s important to call a professional to diagnose and resolve the issue before it leads to more significant damage or costly repairs.
