Performed air duct cleaning and sanitation on a 3 Bedroom single system house. All vents and ductwork are clear of dust and debris at this time. Unable to test system as the air handler was not functioning upon arrival. Customer said it hasn’t worked in a few weeks. Recommend duct cleaning every 3-4 years. Thank you for your business! There is a small chip in the floor that was noted upon arrival. Pic included.
