“I don’t get it why would we want to make the house so tight that you would need ventilation?”


I was asked this question by a potential customer. I think that this is certainly valid question. I answered it to the best of my ability within the short amount of time. I explained that the mantra of our industry is to seal it tight and ventilate it right. I explained the positive impact on IAQ and reducing the amount of infiltration from the dirty attic. I said our goal was make the house safe and comfortable and we would naturally become more efficient. That our repairs would work 24 hours a day hot or cold rain or shine.
I explained that the house was already tight and our measures would make it tighter and ventilation was necessary if the work was to be performed. ”but I keep windows open all the time” she replied. I explained that the ventilation would still be needed in case the windows were not open. And that filtered fresh air is a good thing. I explained that this is not a new thing as commercial buildings have been employing ventilation needs for decades. I also explained that current codes here in California have ventilation codes.
“Well I could see it if I had small children but I just don’t see the benefit.”  Our customer base is sometimes willing to listen and sometimes defiant. The fact is that these principals for a performance home are difficult for some folks to accept.  They do not understand nor see the benefit. Nor do they want change.
It is easy for most to grasp the concepts of insulation, duct sealing, windows (as misguided as much of the information is) high efficiency HVAC systems and Photovoltaic’s.  The highest hurdle for most of our customers to understand is Ventilation. The fact that we state we can save you energy and then require a device to be installed that was not currently in the home is counter intuitive. You can’t visibly see stale air or infiltration.
While good ventilation might have the highest positive impact it is in my opinion the hardest concept to sell.
