In Ontario, California, understanding what constitutes an emergency versus a repair that can wait is crucial for managing HVAC system issues effectively. While a complete loss of cooling during a heatwave or a furnace failure in frigid temperatures clearly demands immediate attention, minor performance degradations might allow for scheduled service.
