Quoted customer a total of $185 which included service call charge and an additional $50 to patch over an old supply run that is not in use. Customer had us out to clean air ducts and sanitizing on 06/17/22. The patch is secure and no air is leaking. Did not remove the old ductwork. It is just an abandoned run at this time. Homeowner is aware. Homeowner started ac system to test for air leakage. Please note the ac system is a 1996 Lennox style system and still functional. ***Note that homeowner has an estimate scheduled in August to provide an estimate to add 2 indoor ductless units for 2 rooms on the 2nd floor.***
