Upon my arrival I performed HH14E. I pulled and chemically cleaned the air movement system. Chemically cleaned the heat transfer media coil and the cabinet. Cleaned the outside of both air handlers. Resealed both plenums and moved a 7 inch duct to allow for better air flow to the back room. Installed Reme halo with the air switch and sealed around it. Sprayed the coil with bio fresh and turned the fan on to circulate bio protect through the house hold. Tested the system and made sure it everything was operating properly.
