After being able to live in so many big and drafty houses while growing up, I figured there was little you could do to improve the situation once a house had become leaky enough to present temperature issues.
You believe that there are just too many open holes either inside the attic or within your walls that it would be foolish to address the issue with any sense of urgency.
Sure, I knew that windows are a pressing factor for a home’s energy efficiency, and because it’s so obvious to anyone with a brain that most of the time they can be swapped out plus substituted—that means that there is something a homeowner can do to mitigate a drafty house. As you might expect there is the weatherstrip foam that you can put inside the creases of your doorways leading into your house. This becomes an hour factor in addressing drafts plus poor insulation. But, there was 1 example I saw recently that certainly surprised me. While reading through maintenance tips for central heating plus cooling systems, I was able to see a post about getting your air duct resealed from the inside out. You can have an Heating, Ventilation, and A/C tech coat the inside of your ducts with an adhesive that hardens as well as fills any air gaps, leaks, cracks, or holes. An unusual product called Aeroseal is sprayed inside of your ventilation unit and bonds to the inside surfaces of the air duct. The hour plan costs more money plus requires more product to achieve the same results as having a professional do it by hand. Anyways, if you have drafts due to leaks in old metal air ducts, this could be a gamechanger in addressing your home’s energy efficiency.
