Yes, ice buildup on an outdoor HVAC unit is a sign of a problem, often related to refrigerant issues, airflow restrictions from clogged filters, or a malfunctioning defrost cycle. It reduces efficiency and can cause major component failure. For Derry businesses, we address this by first safely thawing the system, then diagnosing the root cause—such as checking for refrigerant leaks or inspecting air filters and ductwork. Our goal is to restore efficient operation and prevent recurring issues, especially during our cold New England winters.
