Ductwork Sealing

Ductwork SealingeditedDuctwork sealing, at first glance, may appear to be insignificant and a low priority. When you realize that you could be losing 20%-30% of your conditioned(heated or cooled) air that moves through your duct system, you may want to sit up and take notice. It could be costing you several hundred dollars or more each year in wasted energy.

All ductwork will have some leakage at some of the many connecting points throughout your system. There may even be some additional holes or cracks that you can’t see. The older the ductwork, the more chances of leakage. If the ductwork is located in an unconditioned space like an attic, basement, or crawlspace, that can increase the problem. If the leakage is on the return air side, you are sucking in cold air in the winter which makes your system run longer to warm the house. If the leakage is on the supply side, you are paying to heat the attic or crawlspace that you don’t want to heat. In addition, if the leakage is on the return side, you are drawing in dust, moisture, and dirt from the attic, crawlspace, or basement which is not good for your system, and your indoor air quality. If you have ductwork in the garage and it leaks on the return side, in a worst case scenario, you may be drawing toxic Carbon Monoxide in to the ductwork system and distributing it throughout the house.

Why not let our trained technicians at Robert H. Ranck Inc. take care of this? To seal the ductwork that is visible we apply metal tape(not duct tape) and mastic sealant. We also repair and secure the ductwork and can wrap it for additional insulation and utility savings. We also work with a company that can seal ductwork internally with a system called Aeroseal.

Reminder – a duct system that is well-designed and properly sealed will make your home more comfortable, energy efficient, and safer. Contact us for a free inspection and estimate.
