I've been designing my own ERV system for the house and have been weighing all the options, so I had this list in my head. Nothing dramatic, just the reality. We have allergies and like sleeping in a cooler bedroom.

As dramatic as having a runny nose and sneezing all day, having to overuse your asthma inhaler.

Is that really dramatic, or just the reality that needs to be considered in a cost-benefit analysis? Are you a hay fever truther?
