2022APR19 Kianoosh M. Arrived per previous estimate to shop vac out debris and disinfect duct trunk line with camera. Work took 2 hours, found 1 point of entry from pack rats that I sealed with mastic air sealant in the living area. After shop vaccine all noticeable large debris, I was likely able to remove more than 50% of the smaller debris. Cleaned out furnace cavity and blower compartment as well. Disinfected du twirl and system with hospital grade disinfectant spray and added some peppermint drops to help keep rodents and pests at bay. Wet over some additional precautions including filtration, rodent and pest points of entry, referring a good pest control company, and adding a carbon monoxide detector low to the wall.
