My wife works for Vancouver Coastal Health in a large health unit with an HVAC system. Periodically, they blow a product through the ducting and many employees complain of discomfort and illness for days afterward. No idea what they use, my wife tried to find out but their product is in unlabeled containers. Sounds like they're are hiding something to me. I am aware of Microban being used in ducting but I don't know of any other epa certified product. You would think that there would be a movement to install Hydroxyl generators in buildings HVAC systems to purify air.
You are not gonna live this down for a long time @Nomad74And wanding
I couldn't help it Tom. I was wanding with his wand hooked up to his little Cleanco TM. I almost threw the wand through the wall. I'm used to the powerful suction of the SS870You are not gonna live this down for a long time @Nomad74
I hear Redding Ca is always nice.If the event had not been held in a concrete jungle, mine may have come.
Just do what you do at home. Go in the bushes.I'd be afraid of the bathrooms in California
John, I was not aware of that. I know that HVAC businesses are required to be licensed as contractors in Arizona through the Registrar of contractors, but are individual techs required by law to be certified? Who is the acceptable certifying body?only certified HVAC technicians should be cleaning the coils. At least that is the law in AZ.
