I’ve been looking into ways to improve the energy efficiency, air quality and comfort of my home.
I’ve read countless blogs on the best heating and cooling systems and how to optimize performance.
The standard advice is to regularly change air filters and schedule professional maintenance for the heater in the fall and the air conditioner in the spring. Various articles provide energy saving tips such as caulking, weatherstripping, installing ceiling fans and investing in new windows, insulation and thermal-lined drapes. Just recently, I ran across a website devoted to the upkeep of the duct system. According to the information I found, the majority of homes sacrifice up to 30% of heated and cooled air to imperfections in the ductwork. Small holes, gaps, leaks at the seams and improper installation allow the air to escape from the supply ducts. Flaws in the return ductwork can draw in dust, fumes, VOCs, moisture and all kinds of contaminants that pollute the breathing air. It’s recommended to have the ductwork inspected, tested and serviced every three to five years. I wondered how a contractor would access the system of pipes to make repairs. After a little more research, I discovered information about Aeroseal duct sealing. This process eliminates the need to manually locate and fix holes in the ductwork one by one. The technician first blocks off all supply and return registers. Highly pressurized air is then pumped into the ductwork. As the air leaks from any holes or gaps, adhesive polymer particles stick to the edges. They steadily buildup to create an airtight seal. The Aeroseal procedure takes a couple of hours. The results are verified by computer program and they are backed by a ten-year warranty.
