Frequently Asked Questions
Does duct cleaning improve heating and AC efficiency?
Air duct cleaning may improve heating and AC efficiency when significant dust and debris buildup restricts airflow. Removing these obstructions helps air circulate more freely, reducing strain on the blower and supporting efficient heating and cooling. However, duct cleaning does not replace cleaning dirty coils, changing air filters, or regular HVAC maintenance. Helt can assess your ductwork and recommend cleaning when needed.
