Aeroseal is one of the most effective ways to improve your HVAC air conditioning and heating duct systems. Aeroseal will take a home that typically can have around 40 percent loss of heating or cooling energy and bring it down to as low as 2% loss.
By improving the efficiency of your system by sealing your ducts, you will actually prolong the life of your furnace and air conditioning unit. Most people find that Aeroseal lasts for at least 10 years. In fact, it’s guaranteed that long. However, we have pressure tested it for up to 40 years and have found that it’s still going strong.
Your duct sealing should last for as long as you own your home. In addition to lowering your bills, duct sealing can help give you cleaner air at home. If you struggle with allergies or asthma, this process may help you breathe better, too.
Our philosophy is simple, we always want to maintain equipment to give it the longest life possible. Next, we want to focus on repairing when something goes wrong. Then only as the last choice, we replace equipment when needed. That’s the John Owens Way.
