According to ENERGY STAR, you can improve the efficiency of your heating and cooling system by as much as 20 percent by sealing and insulating your duct.
Your duct carries the warm or cool air into your home and it can be one of your biggest energy wasters in your home if it is inefficient. The average we see when we measure a home’s duct loss is about 20 percent of capacity.
When you are sealing your duct you are taking the energy of the hot or cool air that you already paid for and bringing more of that into your house and not in your crawl space or attic depending on the location of your duct. The reason for the leakage is the duct is put together for your house but it is not air tight with the metal joints, screws, and tape.
We actually use a process that seals the duct from the inside out with an aerosol product. It is not harmful for you or your duct system and, on average, we bring the leakage from 20 percent down to 3–5 percent. A big savings for you on energy and a big difference in your comfort.
Keep the heating and air conditioning that you already paid for and consultant with a professional about if duct sealing is the right option for you.
