Now, that’s not to say that sealing your home is a bad thing. Using LEED glass in your windows does keep heat in and increase heating efficiency. Air filters do help eliminate pollutants and pathogens from the outside than can make you sick. Good insulation and intact ductwork do help keep your home comfortable and efficient in both the cold and hot months.
So, sealing your home is not a bad idea. The trick is to not go overboard and seal it up so tightly that you are crossing the threshold from having a healthy home to having a giant Petri dish. You want to have a home that is insulated, but not vacuum sealed. You want a home with filtered air, but still plenty of air exchange with the outside world. Thankfully, mechanical ventilation is a way to both keep your home energy efficient and keep your indoor air from getting stale.
To help you with this endeavor, there are guides available online, such as at the ENERGY STAR website. In addition, it is a good idea to consult with a professional and ask plenty of questions when building a new home or making improvements to your current one. A qualified Redmond HVAC technician will know how to insulate and ventilate your home properly to protect your family’s health.
