You know you could patent that as an energy saving device. The lint would all be trapped in the tote, so only the warm air would be blowing out. You could have a three-way valve and pipe the hot air coming out of the "lint interceptor" into the return duct to save on heat bills.
can't imagine all the good nasty stuff that grows in there.... only to be expelled onto the people relaxing on the front porch.....
Wonder why they didn't just redirect since they were up there anyway.
Which makes more sense to you? CONSERVATION - turning your thermostat back and being uncomfortable. Maybe saving 5-10% ENERGY EFFICIENCY - leaving your thermostat where everyone is comfortable. Saving 30-70%
