Discussed issues with Walter and Stephanie. Home remains a constant humidity level between 50 and 60% during summer and sometimes can climb in the low 60s during heavy rains. Issues are with smell they are expereincing with unit when switching from heating to cooling which is indicitive of dirty sock syndrome. There is currently an Aprilaire carbon filter on the system and an Apco air scrubber. The other issue they have is with the zoning. The 2nd floor was not cooling properly and the first floor would overcool. Tested zoning to ensure each zone is operating properly and each damper is set for correct bleed. They did say it was working better since Dan made some adjustments but was not able to test under heavy load due to weather. Suggested running it again in summer and there is additional small adjustment that can be made to 2nd floor damper bleed. (can be opened a little more.). Need to look into the coil cleaning chemicals needed as there are sensitivities around using ch
