Not helpful
I fogged my house and HVAC system and used Concorbiun spray in my crawlspace. Less than five weeks later I noticed mold around my HVAC supply vent and called biocide. They were not helpful, gave wrong information about other products, and after 30 minutes of a sales pitch basically hung up on me when it was clear I wasn’t going to spend $1000 on more products right then on the phone. It’s unclear how much the fogging helped, I understand mold remediation is very tricky, but I expected better support on next steps. Very disappointed.
