Ductwork sealing fixes comfort complaints

The house stays cleaner and smells better

Over the course of a year, I noticed that the bedrooms were consistently overheated in the summer and rather chilly in the winter. I blamed the ductwork. I figured there were leaks at the seams allowing the heated and cooled air to escape. I did some research and learned that the majority of homes sacrifice up to 30% of conditioned air to holes in the ducts. I hired a local HVAC contractor to provide duct sealing. The process was much less expensive than I expected. The technician first blocked off all of the supply and return registers and then pumped pressurized air into the system. This air contained polymer particles that are non-toxic, leave behind no residue and yet are adhesive. As the air leaked out of the various imperfections, the sticky particles collected along the edges until they gradually built up an airtight seal. The process was completed in a little over an hour. The HVAC technician then tested the ducts and verified the results by way of a computer generated report. This innovative style of duct sealing is called Aeroseal and it is guaranteed to last for ten years. I was relieved that there was no damage, no mess and no unpleasant smells. Plus, having the duct system sealed eliminated the uneven temperatures throughout the house. I have also noticed a significant savings on monthly energy bills, The air conditioner and furnace no longer need to run as long or as often. The house stays cleaner and smells better. I am now making it a point to have the ductwork professionally inspected every year.
