Tech arrived to give quote on duct repairs and potential work. Homeowner had duct work that was chewed through with rodents in crawlspace and in need of cleaning. Checked ductworkt and found several ducts torn apart, and several ducts old as the house. Ductwork is in need of replacement and additional repairs. Homeowner agreed to replace ductwork for downstairs which includes 5 6 inch supplies and 2 10 inch returns. Also installed ApcoX Ultra for same system. After repairs, verified operations and airflow. Adjusted airflow down on system with dip switch settings. System is operational at techs departure. Thank you for letting TE CERTIFIED service your home.
