I'm getting word of a rash of energy auditor scammers and hacks who seal up mechanical vents and chimneys in an effort to cheat the blower door test then leave these vents sealed! Reports indicate fireplaces, heater flues, HRV intakes, combustion air intakes, furnace ins & outs, WH terminations, dryer vents--ALL have been found sealed and the trend seems to indicate there are some fly-by-night scammers doing this on purpose just so they can collect on their 'weatherization' and energy improvements. This is really dangerous!

Just thought you guys should be on the lookout.
