For a long time our energy bills were just too high. I instantly was ready to blame our HVAC equipment. It was old, destructiond as well as dirty. No wonder our bills were so high. I had a HVAC corporation over to the house to do some cleaning, tightening as well as repairing. There was a small loose part as well as another one that was covered in rust. After the repairs I was ready to experience lower energy bills. Nope, everything stayed the same. I started googling what was the problem. I was closing the curtains in the Summer to avoid the hot light coming in. In the Winter I put towels under the doors to stop air from leaking out. I even caulked around all the windows. So what was the problem? I called our HVAC corporation back as well as told him about our energy troubles. He instantly knew what was up. The guy inserted a camera into our air duct to take a peak. He found a easily small tear along a seam of our air duct. That small tear meant all the treated air our HVAC created was leaking outdoors. How the guy performed air duct sealing was entirely cool. He took what looked love a squirt gun as well as shot it into our air ducts. It was air that had sealant particles in it. The sealant can repair major holes to minor tears love mine. After messing around with that, he checked the camera again as well as fixed the tear. I noticed a difference in our energy bills instantly afterwards. It is amazing how much of a change it was.
