Performed air duct cleaning and sanitation on a 3 bedroom 2 system home. All vents and ductwork are clear of dust and debris at this time. Both systems are functioning properly at this time. Recommend duct cleaning every 3-4 years. Thank you for your business! Neither system is optimal for an air cleaner. Recommend a u.v Reme halo u.v for the main system. Unico system would need to to have something fabricated to install the uv light as it is all flex.
