When it comes to making your HVAC system more efficient, you might be worried about your antiquated furnace or that rickety air conditioner more than you are about your vents. However, leaking vents can send carefully heated or cooled air into wall voids or rooms where you won't use it, which can waste a ton of energy. I had this problem a few years ago, and it was driving up the price of my monthly gas and power bill. This blog is all about improving your HVAC system by carefully sealing up damaged ventilation lines. You never know, sealing a junction gap or a simple leak could help you to lower expenses and keep your home more comfortable.
